Exploits were delivered through phishing campaigns or compromised download repositories, targeting both individual users and business networks.
Observed Attack Campaigns
Forensic analysts found evidence of the vulnerability being actively exploited to deploy information stealers, remote access trojans, and file encryption ransomware. Several well-publicized incidents occurred in Eastern Europe, where business endpoints were compromised en masse through malicious email attachments referencing financial or legal documents.
The Russian dark web community circulated proof-of-concept code with instructions for malware developers to customize payload delivery for maximum impact.
Vendor Response and Required Actions
WinRAR issued a high-priority patch, urging all users to update immediately. Incident response teams recommend re-imaging systems impacted since July and implementing strict policies disallowing downloads of compressed archives from untrusted sources.
Security professionals warn that persistence mechanisms installed through the exploit may survive even after patch deployment, necessitating thorough compromise assessment.
