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.

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.
