Plus: Microsoft fixes 78 vulnerabilities, VMWare plugs a flaw already used in attacks, and more critical updates from June.

Summer software updates are coming thick and fast, with Apple, Google, and Microsoft issuing multiple patches for serious security flaws in June. Enterprise software firms have also been busy, with fixes released for scary holes in VMWare, Cisco, Fortinet, and Progress Software’s MOVEit products.

A significant number of security bugs squashed during the month are being used in real-life attacks, so read on, take note, and patch your affected systems as soon as you can.

Apple

Hot on the heels of iOS 16.5, June saw the release of an emergency iPhone upgrade, iOS 16.5.1. The latest iPhone update fixes security vulnerabilities in WebKit, the engine that underpins Safari, and in the kernel at the heart of the iOS system.

Tracked as CVE-2023-32439 and CVE-2023-32434, both issues are code-execution bugs and have been used in real-life attacks, Apple said on its support page.

While details about the already exploited flaws are limited, security outfit Kaspersky revealed how the kernel issue was used to perform “iOS Triangulation” attacks against its staff. Impactful because they require no interaction from the user, the “zero click” attacks use an invisible iMessage with a malicious attachment to deliver spyware.

Apple has also issued iOS 15.7.7 for older iPhones fixing the Kernel and WebKit issues, as well as a second WebKit flaw tracked as CVE-2023-32435—which was also reported by Kaspersky as part of the iOS Triangulation attacks.

Meanwhile, Apple released Safari 16.5.1, macOS Ventura 13.4.1, macOS Monterey 12.6.7, macOS Big Sur 11.7.8 , watchOS 9.5.2 and watchOS 8.8.1.

Microsoft

Microsoft’s mid-June Patch Tuesday includes security updates for 78 vulnerabilities, including 28 remote code execution (RCE) bugs. While some of the issues are serious, it is the first Patch Tuesday since March that doesn’t include any already exploited flaws.

The critical issues patched in the June update include CVE-2023-29357, an elevation of privilege vulnerability in Microsoft SharePoint Server with a CVSS score of 9.8. “An attacker who has gained access to spoofed JWT authentication tokens can use them to execute a network attack which bypasses authentication and allows them to gain access to the privileges of an authenticated user,” Microsoft said.

“The attacker needs no privileges, nor does the user need to perform any action,” it added.

Meanwhile, CVE-2023-32031 and CVE-2023-28310 are Microsoft Exchange Server remote code execution vulnerabilities that require an attacker to be authenticated to exploit.

Google Android

It’s time to update your Google Android device, as the tech giant has released its June Security Bulletin. The most serious issue fixed by Google is a critical security vulnerability in the System component, tracked as CVE-2023-21108, that could lead to RCE over Bluetooth with no additional execution privileges needed. Another flaw in the System tracked as CVE-2023-21130 is a RCE bug also marked as critical.

One of the flaws patched in June’s update is CVE-2022-22706, a vulnerability in Arm components that the chipmaker fixed in 2022 after it had already been used in attacks.

Stalkerware-type app LetMeSpy has been hacked, with the attacker taking user data with it, the service has announced.



(Read more...)




The post Spyware app LetMeSpy hacked, tracked user data posted online appeared first on Malwarebytes Labs.

Stalkerware-type app LetMeSpy says it has been hacked, with the attacker taking user data with it.

From the message posted to the login screen on the LetMeSpy website:

> On June 21, 2023, a security incident occurred involving obtaining unauthorized access to the data of website users.
> 
> As a result of the attack, the criminals gained access to e-mail addresses, telephone numbers and the content of messages collected on accounts.

To be clear, much of the data that was stolen is the data from the phone which has the tracking app on it, which has likely been installed without the phone owner's knowledge. That's because LetMeSpy is often invisible to the phone's owner. 

So as long as someone can get quick access to install an app on your Android phone, they can monitor you. Once the app is on your phone, you often can't tell it's there. However, in the background, it is maliciously uploading all your calls, texts, and location to the LetMeSpy servers, which is what has now been hacked.

These sorts of apps have been used by people wanting to monitor their partner's movements, along with parents and employers.

Polish site Niebezpiecznik first reported the breach. In the database file which was later dumped online, the blog said there was:

*   26,000+ email addresses of the tool's "operators" along with hashes of their passwords.
*   16,000+ text messages, including passwords and codes for various services
*   Telephone numbers of people who had contacted the tracked phones
*   Telephone numbers of the people whom the tracked phone owner had called (along with the names associated with them in the contacts list)
*   Database dump in SQL format, containing more data, including locations

Spokesman Adam Sanocki for the Polish data protection authority UODO confirmed to TechCrunch that it had received a breach notice from LetMeSpy. When many breaches happen, the affected company should inform users that their data has been breached. But the users of the service here are the ones tracking people, and, sadly, it's unlikely they're going to let the people they are spying on know that their data has been taken.

**How to prevent spyware and stalkerware-type apps**

*   Set a screen lock on your phone and don't let anyone else access it
*   Keep your phone up-to-date. Make sure you're always on the latest version of your phone's software.
*   Use an antivirus on your phone. Malwarebytes for Android shows you exactly what information you're sharing with each app on Android, so you can keep an eye on your privacy. Malwarebytes detects the LetMeSpy app as Android/Monitor.LetMeSpy.

Spyware app LetMeSpy hacked, tracked user data posted online

Apple's emergency patch, AI-generated art and more security headlines from the past week.

Thursday, June 29, 2023 14:06

Welcome to this week’s edition of the Threat Source newsletter.

AI-generated art is causing drama across the internet over the past few months, from Marvel TV show opening credits scenes to predatory YouTubers who claim YOU can make millions by having AI tools create children’s books for you.

There are all sorts of ethical and legal implications that AI-generated art has that I don’t have the space here to cover, but I did think it was worth noting that these tools are already being used in cyber attacks and online scams.

These tools can create extremely convincing deepfake art that could lead to the spread of misinformation or disinformation, especially concerning major news events and political figures. I’ve written about this in the newsletter before.

There are also dozens of apps that promise to create convincing AI art or portraits of people serving another malicious purpose. As McAfee pointed out in this blog post, some Android apps offered to “zhuzh up” users’ profile pictures with AI filters but were actually trojanized apps with hidden information stealers. And at the end of the day, they were all using the same basic filters. Many of these apps could also be stealing and re-using the pictures users submitted to these apps (remember the saga of the app that showed what it would be like when you got old?).

I have more to get to this week, so I’m not going to go much deeper into the subject, but as always, be vigilant of apps’ privacy policies and do a quick background check on their creators before downloading something hoping to create a Skrull version of yourself.

I’m also excited to show off this new video featuring a behind-the-scenes interview with Talos.

This video from Cisco Secure shines a spotlight on the evolution and future of ransomware. Watch it below or over on Cisco.com here to find out how our threat hunters identify new and evolving threats in the wild, and how their research and intelligence help organizations build strong defenses.

**The one big thing**

Apple released an emergency patch last week for all its operating systems for two zero-click vulnerabilities that could allow an attacker to completely take over a targeted device. The two vulnerabilities, identified as CVE-2023-32434 and CVE-2023-32435, were used to reportedly compromise phones in Russia. The issues were part of the so-called Triangulation spyware discovered on iPhones of employees of Kaspersky, a Russia-based cybersecurity company, but the malware was removed from phones after a device reboot.

**Why do I care?**

The chances of being targeted by the Triangulation spyware is slim-to-none based on what the security community knows to this point, but either way, the existence of a zero-day vulnerability in iOS is always big news. Apple encouraged users to upgrade to iOS 16.5.1 and iPadOS 16.5.1 for users of those devices. The company also said that CVE-2023-32434 "may have been actively exploited against versions of iOS released before iOS 15.7."

**So now what?**

All Apple users should update these affected products as soon as possible. The U.S. Cybersecurity and Infrastructure Security Agency also released an advisory telling “users and administrators to review \[Apple’s\] advisories and apply the necessary updates.”

**Top security headlines of the week**

The self-identifying hacktivist group “Anonymous Sudan” is **more active than initially thought.** While researchers are still unsure as to the group’s connections to any nation-states, the group says it’s advocating on behalf of Sudan. It first came onto the scene earlier this month, taking credit for a distributed denial-of-service attack against Microsoft that affected Outlook. Now, researchers are saying their activities actually started prior to that with attacks targeting Israel, Sweden and other nations earlier this year. Microsoft confirmed last week that a Layer 7 DDoS attack was responsible for outages affecting Azure, Outlook and OneDrive, saying that, “these attacks likely rely on access to multiple virtual private servers (VPS) in conjunction with rented cloud infrastructure, open proxies, and DDoS tools” and that there is “no evidence that customer data has been accessed or compromised." (Bloomberg, Bleeping Computer)

**The list of companies affected by the MOVEit breach continues to grow.** Clop, the threat actor behind the attacks, added Schneider Electric and Siemens Energy — two major electric corporations — to its leak site this week. The University of California Los Angeles (UCLA) also confirmed it discovered on June 1 that it was the target of the campaign, though it quickly engaged the college’s incident response team and patched the issue. Since the attack went public, Clop’s leak site mainly called out seven U.S. state and local governments, including the nation’s largest public-employee pension fund — the California Public Employees’ Retirement System. And the New York City public school system was also affected, with more than 45,000 students having their personal data stolen, including sensitive information like Social Security numbers. (The Record by Recorded Future, CyberScoop)

**The FBI seized the domain belonging to the infamous hacking site BreachForums,** three months after arresting its creator. Users of BreachForums were known for sharing and selling stolen personal data from a variety of websites and companies. BreachForums was quiet for several weeks after the admin, known as “Pompompurin,” was arrested. However, the site’s newest admin decided to launch the site on new servers earlier this month. In addition to the usual display of the law enforcement agencies’ logos who were involved in the takedown, BreachForums’ homepage now also displays an image of the avatar Pompompurin used in handcuffs.

Mobile Security / Malware

Cybersecurity researchers have shared the inner workings of an Android malware family called **Fluhorse**.

The malware "represents a significant shift as it incorporates the malicious components directly within the Flutter code," Fortinet FortiGuard Labs researcher Axelle Apvrille said in a report published last week.

Fluhorse was first documented by Check Point in early May 2023, detailing its attacks on users located in East Asia through rogue apps masquerading as ETC and VPBank Neo, which are popular in Taiwan and Vietnam. The initial intrusion vector for the malware is phishing.

The ultimate goal of the app is to steal credentials, credit card details, and two-factor authentication (2FA) codes received as SMS to a remote server under the control of the threat actors.

The latest findings from Fortinet, which reverse-engineered a Fluhorse sample uploaded to VirusTotal on June 11, 2023, suggest that the malware has evolved, incorporating additional sophistication by concealing the encrypted payload in a packer.

"Decryption is performed at the native level (to harden reverse engineering) using OpenSSL's EVP cryptographic API," Apvrille explained. The encryption algorithm is AES-128-CBC, and its implementation uses the same hard-coded string for the key and initialization vector (IV)."

The decrypted payload, a ZIP file, contains within it a Dalvik executable file (.dex), which is then installed on the device to listen to incoming SMS messages and exfiltrate them to the remote server.

"Reversing Flutter applications statically is a breakthrough for anti-virus researchers, as, unfortunately, more malicious Flutter apps are expected to be released in the future," Apvrille said.

Mobile Security / Privacy

Android-based phone monitoring app **LetMeSpy** has disclosed a security breach that allowed an unauthorized third-party to steal sensitive data associated with thousands of Android users.

"As a result of the attack, the criminals gained access to email addresses, telephone numbers and the content of messages collected on accounts," LetMeSpy said in an announcement on its website, noting the incident took place on June 21, 2023.

Following the discovery of the hack, LetMeSpy said it notified law enforcement and data protection authorities. It's also taking steps to suspend all account-related functions until further notice. The identity of the threat actor and their motives are currently unknown.

The work of a Polish company named Radeal, LetMeSpy is offered as a monthly subscription ($6 for Standard or $12 for Pro), allowing its customers to snoop on others simply by installing the software on their devices. An Internet Archive snapshot from December 2013 shows that it's billed as a tool for parental or employee control.

LetMeSpy comes with a wide range of features to collect call logs, SMS messages, and geolocations, all of which can be accessed from the website. In an attempt to evade detection and removal, the app's icon can be hidden from the device's home screen launcher.

As of January 2023, the stalkerware app has been used to track 236,322 phones across the world, harvesting over 63.5 million text messages, 39.7 million call logs, and 43.2 million locations.

Polish security research blog Niebezpiecznik, which first reported the breach and analyzed a dump of the stolen data, said it includes about 26,000 email addresses, 16,000 SMS messages, and a database of victims' locations.

A further review of the leaked information by TechCrunch has revealed that the data goes all the way back to 2013, when LetMeSpy became operational. The records also contain data from at least 13,000 compromised devices. A majority of the victims are located in the U.S., India, and parts of Africa.

CVE-2023-34834: MCL-Collection V4

With at least 13,000 compromised devices in the data leak, it is still unknown who the threat actor is or whether or not victims will be personally notified.

LetMeSpy, an Android phone-tracking company that has been used to track more than 236,000 phones, was hacked on June 21, resulting in threat actors gaining unauthorized access to its users' data dating as far back as 2013.

The hack was discovered by a Polish security research team at Niebezpiecznik, which contacted the maker of the spyware app — but the researchers instead received a response from the threat actor, suggesting the person had taken over the LetMeSpy domain. It is unknown who the threat actor is or what the motives are. 

The phone-tracking app, designed to be hidden from the home screen of a phone in order to remain undetected, was created for and marketed toward parents to control the phone usage of minors and for employers to monitor employees. But the app can also be used in more malicious and threatening "stalkerware" ways, such as an abusive spouse planting the app in a partner's phone, allowing access to any data the stalker deems necessary. Once the app is downloaded, it uploads information — including texts, call logs, and location data — so that an individual can be tracked to a precise location.

**Target for Leaks and Hacks**

Because they have a deep level of accessibility into phone, these types of apps are targets for leaks and hacks.

"The database we reviewed contained current records on at least 13,000 compromised devices, including detailed phone records, though some of the devices shared little to no data with LetMeSpy (LetMeSpy claims to delete data after two months of account inactivity)," stated TechCrunch, which obtained a copy of the leaked data.

LetMeSpy has stated that it has notified law enforcement and its local data protection authority, UODO, but it is unknown as to whether or not it will be notifying victims who have compromised phones.

Searching the source via JADX-GUI revealed the de-facto list of vulgar words & the regex word filter accomplished via client-side filtering\* so I proceeded to edit that wordlist.

APK Easy Tool was effective in providing a turn-key solution to decompile, sign & recompile the 'Hello Cup'(v1.3.1) Application.

The first step was to retrieve the Smali resource files that is essentially specialized assembly language code that is used to represent the Dalvik bytecode of Android applications & specific to the Android runtime environment.

Because I quit ‘Pokemon GO’ only the string 'pogo' will be restricted & everything else previously banned such as 'ugly' (really?) will no longer be filtered.

As a result the message 'UGLY POGO STICK' previously rendered as '\*\*\*\* POGO STICK' will now display 'UGLY \*\*\*\* STICK'.

Although modifying the application was trivial, it served as an interesting illustration bypassing client-side filtering.
