Fake Minecraft Sites Are Still Spreading WeedHack After C2 Takedown

Security Affairs

Despite a recent takedown of its command-and-control servers, the WeedHack malware is still being distributed through fake Minecraft client websites. McAfee Labs reported that there are currently ten active malicious sites, along with several file-hosting accounts, that continue to spread this infostealer. The attackers are using SEO poisoning techniques to ensure these harmful downloads appear at the top of Google search results, making it easier for unsuspecting users to find them. This ongoing campaign puts Minecraft players at risk, as they may unknowingly download software that compromises their personal information and gaming accounts. The persistence of these sites even after efforts to disrupt the malware's infrastructure underscores the need for users to be vigilant about where they download software from.

AI supply chain risk is showing up in developer workflows first

Help Net Security

In a recent interview, Dr. Jaushin Lee, CEO of Zentera Systems, pointed out that AI supply chain risks are primarily affecting developer workflows and open-source package repositories. He noted that while some issues like poisoned model weights and compromised servers are mainly seen in research settings, the real-world impact is felt in the everyday work of developers. Dr. Lee emphasized that companies might gain more risk reduction from proper segmentation of their systems than from investing heavily in new tools. He also mentioned the shortcomings of self-hosting AI models and suggested that software teams could benefit by adopting certain semiconductor isolation practices. This conversation brings attention to the evolving risks in AI development and the need for better security practices in software development environments.

New TCG guidance gives buyers a way to test PQC-ready TPM claims

Help Net Security

The Trusted Computing Group (TCG) has released new guidelines for Trusted Platform Modules (TPMs), which are essential components that secure a device's cryptographic keys and firmware integrity. These guidelines specifically address how TPMs can be deemed quantum-safe, a growing concern as quantum computing technology advances. Now, buyers can request proof from vendors that their TPMs meet these new standards, ensuring they are prepared for future quantum threats. This is significant for companies looking to protect their data from potential quantum attacks, as it provides a way to verify the security claims made by manufacturers. The move aims to enhance the overall security landscape as businesses transition to quantum-resistant technology.

Developer alleges Alibaba uses audio fingerprinting for web tracking

SCM feed for Latest

Matt Callaghan, a software engineer, has raised concerns that Alibaba's website may be using audio fingerprinting techniques for tracking users. He found that the site employs obfuscated audio scripts that create a waveform and analyze its output, which could allow the company to monitor user behavior in a way that bypasses traditional tracking methods. This discovery raises significant privacy issues, as it suggests that users may be unwittingly tracked through audio signals emitted from their devices. The implications are serious, especially for individuals who value their privacy online. The use of such techniques could lead to increased scrutiny from regulators and may prompt users to reconsider their interactions with the site.
