Top Malware Reported in the Last 24 Hours
Advanced fileless malware campaign detected
A sophisticated malware campaign was seen employing a VBA macro to download and execute a 64-bit Rust binary, facilitating fileless injection techniques. Leveraging CLR hosting, the malware loads a malicious AgentTesla payload into memory without writing files to disk. It patches APIs like “EtwEventWrite” and disables Event Tracing for Windows, followed by a shellcode download containing the payload. The shellcode dynamically resolves APIs, decrypts the payload, and executes it in memory.
Python RAT delivered via Fake job offers
A new cyber campaign dubbed "Dev Popper" tricks software developers with fake job interviews, leading them to download a Python RAT. Orchestrated by North Korean threat actors, the attack employs multi-stage social engineering tactics. Victims are instructed to run code from GitHub during the interview, unknowingly activating the RAT. Once installed, the trojan gathers system data and enables remote access.
New Windows ransomware menace
KageNoHitobito, a newly discovered ransomware, has surfaced to target Windows users worldwide. Believed to spread via file-sharing services, and wrapped as legitimate software or game cheats, it strategically avoids critical system files to ensure system functionality. Victims are directed to a TOR site for negotiation, utilizing the AbleOnion chat platform.
