Just days after we uncovered a campaign targeting Google Ads accounts, a similar attack has surfaced, this time aimed at Microsoft advertisers. These malicious ads, appearing on Google Search, are designed to steal the login information of users trying to access Microsoft’s advertising platform.

Microsoft does purchase ad space on its rival’s dominant search engine; however, we found Google sponsored results for “Microsoft Ads” (formerly known as Bing Ads) that contained malicious links created by impostors.

Through shared artifacts, we were able to identify additional phishing infrastructure targeting Microsoft accounts going back to a couple of years at least. We have reported these incidents to Google.

**Fake Microsoft Ads caught on Google Search**

Microsoft made an estimated $12.2 billion in search and news advertising revenues (including Bing) in 2023, which pales in comparison to its rival, Google, holding a much larger share of the search engine market.

Since the advertising ecosystem allows for an open competition between brands, Microsoft is trying to get traffic and earn clicks from Google searches. During our investigation, we saw sponsored results for Microsoft Ads and Bing Ads that managed to slip through Google’s security checks:

**Redirection, cloaking and Cloudflare**

The threat actors are using different techniques to evade detection and drop traffic from bots, security scanners and crawlers. Unwanted IP addresses (_e.g._ VPNs) are immediately redirected to a bogus marketing website (_Figure 2_). This is also known as a “white page”, meaning it looks innocent and hides its maliciousness.

Figure 2: Cloaking page

Users that appear to be genuine are presented with a Cloudflare challenge to verify they are human. This is a legitimate instance of Cloudflare, unlike the “ClickFix” type-of-attacks that have become very common place and trick people into pasting and executing malicious code.

Figure 3: Cloudflare verification

**Rickroll for the cheaters**

After a successful Cloudflare check, users are redirected to the final phishing page via a special URL, that acts as some sort of entry point for the malicious domain _ads\[.\]mcrosoftt\[.\]com_. You can see the network requests related to this redirection chain in _Figure 4_ below.

Figure 4: Network traffic for full redirection

If you were to visit that domain directly instead of going through the proper ad click you’d be greeted with a rickroll, an internet meme designed to make fun of someone. The sandbox for the web urlscan.io has several examples of crawl requests for URLs on that server (_37.120.222\[.\]165_) that all went to the rickroll.

Figure 5: Rickroll redirect

**Phishing page**

After much subversion, real victims finally see the phishing page for the Microsoft Advertising platform. The full URL in the address bar is meant to imitate the legitimate one (_ads.microsoft.com_).

Figure 6: Microsoft Advertising phishing page

The phishing page gives user a fake error message enticing them to reset their password and seemingly tries to get past 2-Step verification as well. Handling 2FA has become a standard feature in most phishing kits, due to the rise in user adoption of this additional security layer.

Figure 7: Phishing steps

**Larger campaign**

Going back to _urlscanio_, we fed it the special entry URL and it was able to navigate to the phishing page. From there, we can look at the various web requests and find something to pivot on in order to identify additional infrastructure.

The _favicon.ico_ file is one starting point and we can query for any scans that match its hash, excluding the official Microsoft domain. The results show that in the past week, there were several other domains that appear to be related to the theft of Microsoft Ads accounts.

But this campaign appears to go back further at least a couple of years and maybe more, although it becomes somewhat tricky to know if the malicious infrastructure is tied to the same threat actors. It’s worth noting that several of the domains are either hosted in Brazil or have the ‘_.com.br_‘ Brazilian top-level domain.

What we discovered may only be the tip of the iceberg; by starting to investigate compromised advertiser accounts we may very well have opened Pandora’s box. This isn’t only Google or Microsoft ad accounts we are talking about, but potentially for Facebook, and many others. Of course, our scope so far has been Google Search, but we know that other platforms are rife with such phishing attacks.

These recent malvertising campaigns highlight the ongoing threat of phishing through online advertising. While tech companies like Google work to combat these issues, users must remain vigilant. Here are some key steps you can take to protect yourself:

*   **Verify URLs:** Always carefully examine the URL in your browser’s address bar before entering any credentials. Scrutinize URLs for inconsistencies or misspellings.
*   **Use 2-Step verification wisely:** it adds an extra layer of security to your accounts, but you still need to pay attention to requests before granting them access.
*   **Regularly monitor your accounts:** Check your advertising accounts for any suspicious activity such as changes in administrator accounts.
*   **Report Ads:** If you encounter a suspicious ad, report it to for the benefit of other users.

 Microsoft advertisers phished via malicious Google ads 

Managing third-party risk in the SaaS era demands a proactive, data-driven approach beyond checkbox compliance.

COMMENTRY

In June 2023, the MOVEit supply chain attack served as a harsh reminder of the vulnerabilities in our software-as-a-service (SaaS) ecosystem. Third-party risk management (TPRM) in today's world of SaaS applications is no longer just about ticking boxes on a checklist. The old methods, with their static questionnaires and outdated ISO 27001 and System and Organization Controls (SOC) — SOC 1, SOC 2, and SOC 3 — reports are simply not efficient anymore. With cyber threats, such as supply chain attacks and third-party integration exploits, becoming more sophisticated, organizations need a dynamic approach to managing SaaS vendors. Embracing automation, real-time visibility, and targeted assessments are crucial steps to stay ahead of potential risks.

Let's explore how organizations that rely heavily on SaaS apps can evolve their TPRM strategies to face modern security challenges head-on.

**The Growing Complexity of SaaS Oversight**

SaaS adoption is growing rapidly, bringing organizations convenience and flexibility. According to B2BSaaS estimates, the SaaS market was valued at $273.5 billion in 2023 and is expected to grow to $1.2 trillion by 2032. However, this growth also comes with an expanded attack surface and more complex data flows. For organizations handling sensitive customer data and navigating strict regulations, these challenges are critical.

Two trends amplify these challenges:

*   Explosion of SaaS apps: Companies use hundreds of SaaS and cloud apps, many introduced without official approval, complicating security oversight. Shadow IT often results in blind spots, making it harder to assess overall security.
    
*   Evolving threat landscape: Attackers increasingly target third-party vendors. Generative AI (GenAI) has further complicated the landscape, enabling attackers to enhance tactics and exploit integration points, misconfigured cloud services, and stolen credentials. The Okta breach of 2023 demonstrated the potential scale of damage from a supply chain attack.
    

These challenges highlight the inadequacy of relying solely on traditional security questionnaires and annual SOC 2 reports. Continuous visibility into vendors' security practices is essential for effective risk management.

**The Problem With Traditional Third-Party Risk Reviews**

Traditional risk reviews involve substantial manual effort and fall short in addressing modern threats:

*   Inefficient manual processes: Manually sending, tracking, and analyzing vendor questionnaires consumes excessive time and energy and delays the resolution of security issues.
    
*   Superficial questions: Generic Yes/No queries (e.g., "Do your developers follow secure coding practices?") fail to assess the effectiveness of vendors' security measures. More specific questions, tied to real-world scenarios, often yield actionable insights.
    
*   Outdated reports: Reports like ISO 27001 and SOC 2 quickly become obsolete in evolving SaaS environments. The emergence of GenAI has further accelerated the pace of change, necessitating updated, dynamic assessments.
    

**Evolving TPRM to Handle Modern SaaS Challenges**

To tackle these issues, organizations must adopt agile, data-centric approaches to vendor security:

1.  Embrace real-time assurance through trust centers. SOC 2 reports are a starting point, but critical vendors should offer ongoing visibility through automated trust centers. Tools like Sprinto, Drata, and Vento provide real-time insights into security controls and compliance, enabling proactive decisions.
    

1.  Make questionnaires smarter. Replace generic questionnaires with tailored assessments that probe deeper. Focus on how controls are implemented and monitored. For example, shift from "Do you secure ABC?" to "How do you secure ABC, and how do you verify its effectiveness?" Questions that examine metrics and outcomes help uncover the true state of security.
    
2.  Address talent gaps and boost technical expertise. Invest in developing skills in cloud security, SaaS configuration, and API management. Training internal teams or partnering with specialized vendors can bridge expertise gaps. The SolarWinds breach of 2020 underscores the need for visibility into supply chain vulnerabilities. Workshops and certifications can enhance team capabilities, keeping them informed of evolving risks.
    
3.  Include shadow IT and "free" tools. Review unpaid apps, open source tools, and browser extensions — often overlooked but risky. Shadow IT tools, while offering productivity, introduce unknown risks. Assessing these apps before they integrate into workflows reduces unexpected exposure. Include them in audits to ensure they meet baseline security standards.
    
4.  Use modern tools, not spreadsheets. Transition from spreadsheets to SaaS security posture management (SSPM) tools, which monitor misconfigurations, excessive permissions, and suspicious activities. AI-powered tools can further analyze vendor responses and highlight inconsistencies. Leveraging these tools saves time and enhances accuracy.
    

**What Can You Do When Revamping Your TPRM Strategy**

Evolving TPRM processes isn't easy. Avoid common pitfalls:

*   Avoid risky inaction: Delaying updates to vendor management increases exposure. Start with small, impactful improvements and scale gradually.
    
*   Avoid overcommitting resources: Implement changes incrementally, prioritizing high-impact areas. This ensures resource efficiency without overwhelming teams.
    
*   Set realistic expectations for AI: Leverage AI where it adds value while recognizing its limitations. AI tools should complement, not replace, human oversight.
    
*   Ensure team alignment: Align team skills with new vendor security goals. Equip teams to manage technical assessments effectively. Feedback loops can ensure continuous improvement and alignment with organizational objectives.
    

**What We Can Take From This**

Managing third-party risk in the SaaS era demands a proactive, data-driven approach. Organizations must go beyond checkbox compliance by leveraging real-time assurance, tailored assessments, and automation. Modernizing TPRM is essential to address the complexities of SaaS security.

While challenging, particularly for smaller organizations, the benefits of preventing breaches and protecting reputations outweigh the costs. Organizations can manage expenses effectively by prioritizing critical vendors and adopting phased changes while enhancing third-party risk management. The commitment to proactive strategies ensures resilience against an ever-evolving threat landscape.

The Old Ways of Vendor Risk Management Are No Longer Good Enough

Apple has released a host of security updates for iOS, iPadOS, Mac, Apple Watch, and Apple TV. Update as soon as you can.

Apple has released a host of security updates across many devices, including for a zero-day bug which is being actively exploited in iOS.

Apple said:

> “A malicious application may be able to elevate privileges. Apple is aware of a report that this issue may have been actively exploited against versions of iOS before iOS 17.2.”

Devices affected are those that run:

*   iPhone XS and later
*   iPad Pro 13-inch, iPad Pro 12.9-inch 3rd generation and later, iPad Pro 11-inch 1st generation and later, iPad Air 3rd generation and later, iPad 7th generation and later, and iPad mini 5th generation and later
*   macOS Sequoia
*   Apple Watch Series 6 and later
*   All models of Apple TV HD and Apple TV 4K

If you use any of these then you should install updates as soon as you can. To check if you’re using the latest software version, go to **Settings** (or **System Settings**) > **General** \> **Software Update**. It’s also worth turning on Automatic Updates if you haven’t already, which you can do on the same screen.

**Technical details about the zero-day**

The zero-day vulnerability patched in this update is tracked as CVE-2025-24085. It is described as a use after free (UAF) issue in Apple’s Core Media framework that would allow an attacker to elevate privileges.

The Core Media framework handles multimedia applications like photos, videos, and real-time communication applications. UAF is a type of vulnerability that is the result of the incorrect use of dynamic memory during a program’s operation. If, after freeing a memory location, a program does not clear the pointer to that memory, an attacker can use the error to manipulate the program. Referencing memory after it has been freed can cause a program to crash, use unexpected values, or execute code. In this case, successful exploitation could provide a malicious app with privileges on the affected device that it shouldn’t have.

 Apple users: Update your devices now to patch zero-day vulnerability 

The firewall specialist has patched the security flaw, which was responsible for a series of attacks reported earlier this month that compromised FortiOS and FortiProxy products exposed to the public Internet.

Fortinet has patched an actively exploited zero-day authentication bypass flaw affecting its FortiOS and FortiProxy products, which attackers have been exploiting to gain super-administrative access to devices to conduct nefarious activities, including breaching corporate networks.

Fortinet characterized the flaw, rated as critical and tracked as CVE-2024-55591 (CVSS 9.6), as an "authentication bypass using an alternate path or channel vulnerability" that "may allow a remote attacker to gain super-admin privileges via crafted requests to Node.js websocket module," according to a FortiGuard Labs security advisory last week.

Fortinet observed threat actors performing various malicious operations by exploiting the flaw. These activities included: creating an admin account on the device with a random user name; creating a local user account on the device with a random user name; creating a user group or adding a local user to an existing SSL VPN user group; adding and/or changing other settings, including firewall policy and/or firewall address; and logging in to the SSL VPN to get a tunnel to the internal network.

Fortinet recommended that customers using affected products follow the recommended upgrade path on its website to mitigate the flaw. It also offered workaround options in its advisory.

**First Signs of Fortinet Zero-Day Exploitation**

The first signs that something was amiss came earlier this month, when researchers at Arctic Wolf revealed that a zero-day flaw was likely to blame for a series of recent attacks on FortiGate firewall devices with management interfaces exposed on the public Internet. Attackers were targeting the devices to create unauthorized administrative logins and make other configuration changes, create new accounts, and perform SSL VPN authentication.

Fortinet quietly informed its customer base of the issue before revealing the patch and extent of the situation late last week; this low-key revelation is how Arctic Wolf got wind of it, according to a blog post analyzing the flaw by watchTowr Labs published on Jan. 27. However, security researchers did not yet know exactly what the flaw was or what the exploitation entailed.

That's become clearer now. The flaw resided within the jsconsole functionality, which is a graphical user interface (GUI) feature to execute command line interface (CLI) commands inside FortiOS's management interface, according to watchTowr Labs. "Specifically, the weakness in this functionality allowed attackers to add a new administrative account," according to the post.

Jsconsole is a WebSocket-based Web console to the CLI of the affected Fortinet appliances. "This CLI is all-powerful, since it is effectively the same as the actual provided CLI that is used by legitimate administrators to configure the device," according to watchTowr Labs. Therefore, if an attacker gains access to the Web console, the appliance itself should be considered compromised.

The researchers took a deep dive into the vulnerability and found that it was actually a chain of issues combined into one critical vulnerability that allowed attackers to follow four key steps to achieve super administrative access.

Those steps are: creating a WebSocket connection from a pre-authenticated HTTP request; using a special parameter local\_access\_token to skip session checks; exploiting a race condition in the WebSocket Telnet CLI to send authentication before the server does; and picking the access profile that an attacker wishes to assume, which in the case of the researchers' proof-of-concept was to become a super administrator.

**Mitigation & Protection Against CVE-2024-55591**

Fortinet devices are a popular target for threat actors, with vulnerabilities found in the products often widely exploited to breach not only devices but also act as a point of entry to attack corporate networks.

Related:The Case for Proactive, Scalable Data Protection

Organizations using the devices affected by the flaw are advised to follow the appropriate update path or apply the workaround provided by Fortinet.

Fortinet also noted in its advisory that an attacker generally would need to know an admin account's username to perform the attack and log in to the CLE to exploit the flaw. "Therefore, having a non-standard and non-guessable username for admin accounts does offer some protection, and is, in general, a best practice," according to the advisory.

However, the company added, since the targeted WebSocket is not itself an authentication point, attackers still have the possibility of brute-forcing the username to exploit the flaw.

Actively Exploited Fortinet Zero-Day Gives Attackers Super-Admin Privileges

Cisco Talos discovered an ongoing malicious campaign operated by a financially motivated threat actor targeting users, predominantly in Poland and Germany.

Tuesday, January 28, 2025 06:00

*   Cisco Talos discovered an ongoing malicious campaign operated by a financially motivated threat actor since as early as July 2024 targeting users, predominantly in Poland and Germany, based on the phishing email language. 
*   The actor has delivered different payloads, including Agent Tesla, Snake Keylogger, and a new undocumented backdoor we are calling TorNet, dropped by PureCrypter malware.  
*   The actor is running a Windows scheduled task on victim machines—including on endpoints with a low battery—to achieve persistence.  
*   The actor also disconnects the victim machine from the network before dropping the payload and then connects it back to the network, allowing them to evade detection by cloud antimalware solutions.  
*   We also found that the actor connects the victim’s machine to the TOR network using the TorNet backdoor for stealthy command and control (C2) communications and detection evasion. 

**The campaign **

The intrusions start with a phishing email as the initial infection vector. The actor is impersonating financial institutions and manufacturing and logistics companies by sending fake money transfer confirmations and fake order receipts, respectively. The phishing emails are predominantly written in Polish and German, indicating actor’s intent to primarily target users in those countries. We also found some phishing email samples from the same campaign written in English. We assess with medium confidence that the actor is financially motivated, based on the phishing email themes and the filenames of the email attachments.  

The phishing email has attachments with the file extension “.tgz”, indicating that the actor has used GZIP to compress the TAR archive of the malicious attachment file to disguise the actual malicious content of the attachment and evade email detections. 

Sample phishing email in Polish. 

Sample phishing email in German. 

When a user opens the compressed email attachment and manually unzips it and runs a .NET loader executable, it eventually downloads encrypted PureCrypter malware from a compromised staging server. The Loader decrypts the PureCrypter malware and runs it in the system memory.  

In a few intrusions in this campaign, we found that the PureCrypter malware drops and runs the TorNet backdoor. The TorNet backdoor establishes connection to the C2 server and also connects the victim machine to the TOR network. It has the capabilities to receive and run arbitrary .NET assemblies in the victim machine’s memory, downloaded from the C2 server, increasing the attack surface for further intrusions. 

**.NET loader implants PureCrypter **

Talos found that the compressed attachment files contain a large .NET executable file. The actor has instrumented the .NET executable to either download the next-stage malicious executables from a remote staging server or to reflectively load an embedded malicious binary.  

Some of the loader samples we analyzed in this campaign download the AES-encrypted binary of the PureCrypter malware hosted on compromised websites in paths “/filescontentgalleries/pictorialcoversoffiles/” and “/post-postlogin/” using a hardcoded URL. The encrypted PureCrypter binaries were stored with the arbitrary filenames using different file extensions, including .pdf, .dat, .wav, .vdf, .mp3 and .mp4. The loader decrypts the PureCrypter binary and loads reflectively.

In a few other loader samples, we found that the encrypted PureCrypter sample was embedded in the loader, which is decrypted using the AES algorithm and reflectively loaded into the victim machine’s memory.  

Snippet of the loader with embedded PureCrypter binary. 

**PureCrypter drops the TorNet backdoor **

The PureCrypter malware found in this intrusion is a Windows dynamic-link library obfuscated with Eziriz’s .NET Reactor obfuscator. It has resources of encrypted binaries of legitimate DLLs, including Protobuf-net and Microsoft task scheduler DLL along with the TorNet backdoor.  

PureCrypter initially creates a mutex on the victim machine and executes the command to release the currently assigned DHCP IP address of the victim machine, establishes persistence, performs various anti-analysis and detections tasks, drops and runs the payload, and finally executes a command to renew the IP address of the victim machine.  

Cmd /c ipconfig /release 
Cmd /c ipconfig /renew 

The threat actor is likely using this technique to evade detections from the cloud-based anti-malware programs by disconnecting the victim machine from the network and connects back to the network after dropping and running the backdoor.  

The PureCrypter malware performs various anti-debugger, anti-analysis, anti-VM, and anti-malware checks on the victim machine as described below: 

*   It checks if the process is debugged using the function “CheckRemoteDebuggerPresent”. 
*   It checks for the Sandboxie and Cuckoo sandbox environments by enumerating processes to look for “sbieDLL.dll” and “cuckoomon.dll”. 
*   It checks if the DLL is running in the virtual environment by executing the WMI queries and searches for the strings “VMware”, “VIRTUAL”, “AMI”, and “Xen”.  

Select \* from Win32\_BIOS 
Select \* from Win32\_ComputerSystem 

*   It also checks if the process running is associated with “vmGuestLib.dll” to detect the VMWare environment. 
*   It checks if the victim machine username is “john” or “anna” or “xxxxxxxx”.  
*   It checks for the strings “amsi.dll” and “amsiscanbuffer” in the running processes modules of the victim machine.  
*   It checks if the Event Tracing for Windows (ETW) is configured for the victim machine by attempting to check if any processes point to the function “EtwEventWrite” of “ntdll.dll”.  
*   It modifies the Windows Defender settings by executing the PowerShell commands to add its process and the path of the dropped backdoor to the exclusion lists.

Add-MpPreference –ExclusionPath 
Add-MpPreference –ExclusionProcess 

After the evasion checks, PureCrypter decrypts the encrypted backdoor from its resource and drops it to the user profile application temporary folder with a random file name. It also decrypts another file resource using a custom string decryption algorithm, generating the arbitrary filename strings and the task name strings for the Windows Task scheduler.  

PureCrypter establishes the persistence in the Run registry key by adding the path of the loader. It also creates a Windows task using a task name gained by decrypting the strings from the resource file and executes the loader every two to four minutes with no execution time limit. The task can run if the machine switches to battery power and will not stop if it runs on a low battery power. The threat actor has instrumented this technique to possibly ensure an uninterrupted infection avoiding the victim machine operating system to deprioritize the process when a victim machine is running on low battery power mode.

PureCrypter drops a Visual Basic script in the Windows startup folder with the instructions to load and execute the dropped backdoor. 

Code Snippet showing the command to drop and execute a VB Script.

After establishing persistence, PureCrypter loads the dropped backdoor by accessing it through a URL scheme “file\[://\]<Path of the dropped backdoor>” and injects the backdoor into the .NET runtime executable process in the victim machine. The threat actor is using this technique to possibly masquerade the file access activity as a web request in the victim machine logs and to bypass detections for loading a file from suspicious file paths on the victim machine.  

Code snippet showing the process injection.

**Payload TorNet creates a backdoor on the victim machine **

Talos discovered a new .NET backdoor as the payload in the recent intrusions of this campaign, which we call TorNet. TorNet backdoor is also obfuscated with Eziriz’s .NET Reactor obfuscator and has hash values for the compilation time. This could be the artifact that was created when the samples were compiled in Visual Studio with the “/deterministic” parameter. When Visual Studio is configured to generate deterministic binaries, the compiled date/time field of the binaries will be replaced by a hash of the compilation options. Talos had previously seen, and reported this technique used by other threat actors to disguise the actual compilation time of the malware binaries.    

TorNet initially decodes a base64-encoded string to obtain the C2 domain, port number, and an alphanumeric string of 16 characters (5e7a81857a353068). It then performs the anti-debugging, anti-malware, anti-VM, and sandbox evasion checks similar to PureCrypter we discussed in the previous section.  

Code snippet showing the base64 string decoding to obtain the string, C2 domain, and port number. 

After the evasion checks, TorNet establishes a TCP socket connection to the C2 server by resolving the IP address of the C2 domain decoded from the base64-encoded string. The connection uses one of the port numbers 8194, 7890, or 8410. We observed that the C2 domains used by the backdoor were resolving to the IP address 104\[.\]168\[.\]7\[.\]37 during the period of our research. 

TorNet backdoor sample connecting to the C2 using the domain and port number.

After establishing the connection to the C2 server, TorNet sends the gained string “5e7a81857a353068” by decoding the base64-encoded strings to the C2 server, creating a hexadecimal byte stream of length 20 and writes it to a memory stream by compressing it using the GzipStream function.  

HEX stream: “3A 12 12 10 35 65 37 61 38 31 38 35 37 61 33 35 33 30 36 38” 

ASCII equivalent: “:<2-byte place holder>\\n5e7a81857a353068” 

TorNet then generates an MD5 hash value of the string “5e7a81857a353068” and uses it as a key to encrypt the compressed 20-byte hexadecimal data stream using the triple DES algorithm. Using the Bitconverter function, TorNet splits the encrypted byte stream and sends it to the C2 server by writing it to the TCP stream through the socket.

The C2 server may send an arbitrary encrypted .NET assembly as a response to a TorNet’s request. TorNet will decrypt the arbitrary binary and reflectively run it. During our research, we were unable to receive a response from the C2, still analyzing the TorNet binary allowed us to assess that the received response will be an arbitrary .NET assembly code, enabling the attack surface for further attack.

TorNet also connects the victim machine to the TOR network. It downloads the TOR expert bundle from the TOR Project archive site, unpacks it and runs the “tor\[.\]exe” as a background process to connect to TOR.

Once TOR is running, TorNet connects to the TOR network using the TOR SocksPort (127\[.\]0\[.\]0\[.\]1:9050), and with the “socket.Poll” function, it routes all traffic from the backdoor process on the victim machine through the TOR network. The threat actor is leveraging the TOR network to anonymize the C2 communication and evade detection.

Amid ongoing fears over TikTok, Chinese generative AI platform DeepSeek says it’s sending heaps of US user data straight to its home country, potentially setting the stage for greater scrutiny.

The United States’ recent regulatory action against the Chinese-owned social video platform TikTok prompted mass migration to another Chinese app, the social platform “Rednote.” Now, a generative artificial intelligence platform from the Chinese developer DeepSeek is exploding in popularity, posing a potential threat to US AI dominance and offering the latest evidence that moratoriums like the TikTok ban will not stop Americans from using Chinese-owned digital services.

DeepSeek, an AI research lab created by a prominent Chinese hedge fund, recently gained popularity after releasing its latest open source generative AI model that easily competes with top US platforms like those developed by OpenAI. However, to help avoid US sanctions on hardware and software, DeepSeek created some clever workarounds when building its models. On Monday, DeepSeek’s creators limited new sign-ups after claiming the app had been overrun with a “large-scale malicious attack.”

While DeepSeek has several AI models, some of which can be downloaded and run locally on your laptop, the majority of people will likely access the service through its iOS or Android apps or its web chat interface. Like with other generative AI models, you can ask it questions and get answers; it can search the web; or it can alternatively use a reasoning model to elaborate on answers.

DeepSeek, which does not appear to have established a communications department or press contact yet, did not return a request for comment from WIRED about its user data protections and the extent to which it prioritizes data privacy initiatives.

As people clamor to test out the AI platform, though, the demand brings into focus how the Chinese startup collects user data and sends it home. Users have already reported several examples of DeepSeek censoring content that is critical of China or its policies. The AI setup appears to collect a lot of information—including all your chat messages—and send it back to China. In many ways, it’s likely sending more data back to China than TikTok has in recent years, since the social media company moved to US cloud hosting to try to deflect US security concerns

“It shouldn’t take a panic over Chinese AI to remind people that most companies in the business set the terms for how they use your private data” says John Scott-Railton, a senior researcher at the University of Toronto’s Citizen Lab. “And that when you use their services, you’re doing work for them, not the other way around.”

**What DeepSeek Collects About You**

To be clear, DeepSeek is sending your data to China. The English-language DeepSeek privacy policy, which lays out how the company handles user data, is unequivocal: “We store the information we collect in secure servers located in the People's Republic of China.”

In other words, all the conversations and questions you send to DeepSeek, along with the answers that it generates, are being sent to China or can be. DeepSeek’s privacy policies also outline the information it collects about you, which falls into three sweeping categories: information that you share with DeepSeek, information that it automatically collects, and information that it can get from other sources.

The first of these areas includes “user input,” a broad category likely to cover your chats with DeepSeek via its app or website. “We may collect your text or audio input, prompt, uploaded files, feedback, chat history, or other content that you provide to our model and Services,” the privacy policy states. Within DeepSeek’s settings, it is possible to delete your chat history. On mobile, go to the left-hand navigation bar, tap your account name at the bottom of the menu to open settings, and then click “Delete all chats.”

This collection is similar to that of other generative AI platforms that take in user prompts to answer questions. OpenAI’s ChatGPT, for example, has been criticized for its data collection although the company has increased the ways data can be deleted over time. Regardless of these types of protections, privacy advocates emphasize that you should not disclose any sensitive or personal information to AI chat bots.

“I would not input personal or private data in any such an AI assistant,” says Lukasz Olejnik, independent researcher and consultant, affiliated with King's College London Institute for AI. Olejnik notes, though, that if you install models like DeepSeek’s locally and run them on your computer, you can interact with them privately without your data going to the company that made them. Additionally, AI search company Perplexity says it has added DeepSeek to its platforms but claims it is hosting the model in US and EU data centers.

Other personal information that goes to DeepSeek includes data that you use to set up your account, including your email address, phone number, date of birth, username, and more. Likewise, if you get in touch with the company, you’ll be sharing information with it.

Bart Willemsen, a VP analyst focusing on international privacy at Gartner, says that, generally, the construction and operations of generative AI models is not transparent to consumers and other groups. People don’t know exactly how they work or the exact data they have been built upon. For individuals, DeepSeek is largely free, although it has costs for developers using its APIs. “So what do we pay with? What do we usually pay with: data, knowledge, content, information,” Willemsen says.

As with all digital platforms—from websites to apps—there can also be a large amount of data that is collected automatically and silently when you use the services. DeepSeek says it will collect information about what device you are using, your operating system, IP address, and information such as crash reports. It can also record your “keystroke patterns or rhythms,” a type of data more widely collected in software built for character-based languages. Additionally, if you purchase DeepSeek’s premium services, the platform will collect that information. It also uses cookies and other tracking technology to “measure and analyze how you use our services.”

A WIRED review of the DeepSeek website's underlying activity shows the company also appears to send data to Baidu Tongji, Chinese tech giant Baidu's popular web analytics tool, as well as Volces, a Chinese cloud infrastructure firm. In a social media post, Sean O'Brien, founder of Yale Law School's Privacy Lab, said that DeepSeek is also sending “basic” network data and “device profile” to TikTok owner ByteDance “and its intermediaries.

The final category of information DeepSeek reserves the right to collect is data from other sources. If you create a DeepSeek account using Google or Apple sign-on, for instance, it will receive some information from those companies. Advertisers also share information with DeepSeek, its policies say, and this can include “mobile identifiers for advertising, hashed email addresses and phone numbers, and cookie identifiers, which we use to help match you and your actions outside of the service.”

**How DeepSeek Uses Information**

Huge volumes of data may flow to China from DeepSeek’s international user base, but the company still has power over how it uses the information. DeepSeek’s privacy policy says the company will use data in many typical ways, including keeping its service running, enforcing its terms and conditions, and making improvements.

Crucially, though, the company’s privacy policy suggests that it may harness user prompts in developing new models. The company will “review, improve, and develop the service, including by monitoring interactions and usage across your devices, analyzing how people are using it, and by training and improving our technology,” its policies say.

DeepSeek’s privacy policy also says the company will also use information to “comply with \[its\] legal obligations”—a blanket clause many companies include in their policies. DeepSeek’s privacy policy says data can be accessed by its “corporate group,” and it will share information with law enforcement agencies, public authorities, and more when it is required to do so.

While all companies have legal obligations, those based in China do have notable responsibilities. Over the past decade, Chinese officials have passed a series of cybersecurity and privacy laws meant to allow state officials to demand data from tech companies. One 2017 law, for instance, says that organizations and citizens should “cooperate with national intelligence efforts.”

These laws, alongside growing trade tensions between the US and China and other geopolitical factors, fueled security fears about TikTok. The app could harvest huge amounts of data and send it back to China, those in favor of the TikTok ban argued, and the app could also be used to push Chinese propaganda. (TikTok has denied sending US user data to China’s government.) Meanwhile, several DeepSeek users have already pointed out that the platform does not provide answers for questions about the 1989 Tiananmen Square massacre, and it answers some questions in ways that sound like propaganda.

Willemsen says that, compared to users on a social media platform like TikTok, people messaging with a generative AI system are more actively engaged and the content can feel more personal. In short, any influence could be larger. “Risks of subliminal content alteration, conversation direction steering, in active engagement ought by that logic to lead to more concern, not less,” he says, “especially given how the inner workings of the model are widely unknown, its thresholds, borders, controls, censorship rules, and intent/personae largely left unscrutinized, and it being already so popular in its infancy stage.”

Olejnik, of King's College London, says that while the TikTok ban was a specific situation, US law makers or those in other countries could act again on a similar premise. “We can’t rule out that 2025 will bring an expansion: direct action against AI firms,” Olejnik says. “Of course, data collection may again be named as the reason.”

DeepSeek’s Popular AI App Is Explicitly Sending US Data to China

CISOs are planning to adjust their budgets this year to reflect their growing concerns for cybersecurity preparedness in the event of a cyberattack.

NEWS BRIEF

In 2025, chief information security officers (CISOs) will be directing their attention to becoming more cyber prepared in the event of an attack, by enhancing their crisis simulation capabilities.

That's according to a study conducted by researchers at Hack The Box, which found that out of 200 US- and UK-based CISOs, 74% said they plan to up their crisis simulation budgets this year.

These changes likely stem from rising concerns about the growing number of cyberattacks, the lack of incident-response planning, and inadequate stress-testing of crisis scenarios. Major cyberattacks and cyber incidents have impacted organizations such as NHS, 23andMe, and a host of businesses impacted by the CrowdStrike faulty update in 2024, affecting enterprises on a global level. CISOs are trying to reassess their organizations' capabilities in order to manage the chaos when it inevitably arises.

A full 77% of those surveyed said they would allocate greater budgets for cyber-crisis simulations if the exercises themselves were more realistic and actionable. 

"Preparedness is the foundation of resilience, and crisis simulations play a crucial role in testing organizations security and workforce performance when it's most critical," said Haris Pylarinos, CEO and founder at Hack The Box, in a statement. "Organizations are right to prioritize crisis simulation, and must ensure that these are implemented in the right way."

Also, 73% of survey respondents reported that crisis simulations and incident-response exercises for both their technical and non-technical teams were their top business priority this year.

Pylarinos highlighted that crisis simulation will continue to evolve, pairing artificial intelligence with expert knowledge in order to provide tailored and realistic scenarios that reflect challenges that security teams and management will face on digital front lines. "It will unite previously disparate business units as one," he said, "and allow real-world performance to be benchmarked in a controlled environment."
