Attackers launched a campaign distributing trojanized installers for WinSCP and PuTTY in early March 2024, as clicking malicious ads after searching for the software leads to downloads containing a renamed pythonw.exe that loads a malicious DLL.
The DLL side-loads a legitimate DLL and injects a Sliver beacon using a reflective DLL injection technique, where the attackers then establish persistence, download additional payloads, attempt to steal data, and deploy ransomware, which shows TTPs similar to those used by BlackCat/ALPHV in the past
