QEMU Hijacked as Stealth Backdoor for Credential Theft, Ransomware

Attackers are exploiting QEMU virtual machines as stealth backdoors for credential theft and ransomware staging, hiding their operations within invisible environments that evade most endpoint security. This technique, observed in campaigns like STAC4713 and STAC3725, involves running tools inside a Linux VM to harvest credentials, move laterally, and deploy ransomware with minimal artifacts left on the host system.
