Venom Stealer is an active MaaS infostealer campaign targeting Windows endpoints via ClickFix social engineering and fake Avast antivirus sites, enabling continuous credential harvesting, browser data exfiltration, and cryptocurrency wallet draining with no associated CVE and no patch-based remediation path. Organizations should prioritize behavioral detection for browser processes spawning PowerShell, DPAPI-based credential decryption from non-standard processes, and persistent harvesting indicators including scheduled task and registry run-key creation. Immediate mitigations include blocking fake AV domains at DNS and proxy layers, enforcing PowerShell execution restrictions, and mandating MFA across credential-sensitive systems to limit the blast radius of harvested credentials.
