AsyncRAT AsyncRAT is a Remote Access Tool (RAT) designed to remotely monitor and control other computers through a secure encrypted connection. It is an open source remote administration tool, however, it could also be used maliciously because it provides functionality such as keylogger, remote desktop control, and many other functions that may cause harm to the victims computer. In addition, AsyncRAT can be delivered via various methods such as spear-phishing, malvertising, exploit kit and other techniques.AsyncRAT as delivered by MintsLoader includes a PowerShell module with a DGA. The DGA is similar to MintsLoader's DGA, but generates more domains and uses more than one TLD. No Attribution https://malpedia.caad.fkie.fraunhofer.de/details/win.asyncrat

AI detected suspicious PE digital signature
Source: Initial sample Joe Sandbox AI: Detected suspicious elements in PE signature: Multiple critical red flags: 1) Certificate claims to be from Valve/Steam but is issued in China (C=CN) which is highly suspicious as Valve is a US company 2) Compilation timestamp is set to year 2072, which is clearly impossible and a common malware technique 3) Signature is invalid and cannot build trust chain to root authority 4) Organization name in issuer is 'SHA384' which appears to be using a hash algorithm name as an organization, highly irregular 5) While the certificate validity dates (2024-2035) are within reasonable range, the combination with other factors suggests this is a fraudulent attempt to impersonate Valve/Steam
