We’re tracking widespread #ClickFix activity using compromised legitimate websites to deliver fileless malware, lowering suspicion and delaying detection.
⚠️ Finance, banking, healthcare, manufacturing, and tech are among the most exposed industries.
❗️ The activity looks low-risk until fileless execution and outbound C2 traffic are already established. Attackers inject a lightweight inline JavaScript loader into compromised sites, which retrieves a second-stage payload directly into the victim’s browser from external infrastructure.
The attack chain blends into normal web traffic, relies on PowerShell and in-memory execution, and later shifts C2 communication into the legitimate system process svchost.exe, making malicious activity harder to distinguish from routine system behavior for SOC and MSSP teams.
⚡️ #ANYRUN Sandbox helps teams validate suspicious activity faster and contain fileless attacks before they escalate. Analysts can observe the full execution chain in real time:
Inline JS loader ➡️ User-executed PowerShell (IEX/IRM) ➡️ Hidden second-stage PowerShell and loader retrieval ➡️ Fileless in-memory execution inside powershell.exe ➡️ Follow-on .NET payload delivery ➡️ svchost.exe injection ➡️ Custom TCP C2 🚨
