UAC-0145 Deploys ClickFix CAPTCHAs to Deliver Data‑Stealing Malware to Ukrainian Targets
What Happened — Russian state‑sponsored group UAC‑0145 (a Sandworm sub‑cluster) has been observed injecting malicious ClickFix CAPTCHAs into Ukrainian web services. When users solve the CAPTCHA, a hidden payload installs data‑stealing malware on the device.
Why It Matters for Compliance & Audit Readiness
- The attack exploits a classic social‑engineering vector that bypasses technical controls; SOC 2 access‑control criteria (CC6.1 – Security Awareness) require documented training and testing against such tactics.
- Continuous evidence of security‑awareness program effectiveness (e.g., phishing simulations, training completion) serves as audit‑ready proof that the organization mitigates credential‑compromise risk.
Who Is Affected – Primarily Ukrainian government agencies, critical‑infrastructure operators, and any local enterprises exposed to the compromised web services.
Recommended Actions –
- Incorporate CAPTCHA‑based phishing scenarios into your security‑awareness curriculum and conduct regular simulations.
- Verify that MFA is enforced for all privileged accounts to limit impact of credential theft.
- Map the incident to SOC 2 CC6.1 and collect evidence of training, test results, and remediation steps for audit readiness.

Technical Notes – The campaign uses a “ClickFix” technique: a malicious CAPTCHA widget that, once solved, triggers a drive‑by download of a custom data‑stealer. No public CVE is associated; the vector is social engineering rather than a software flaw.
