eScan Antivirus Update Servers Compromised to Distribute Persistent Malware

The update servers of eScan Antivirus, a solution developed by the Indian company MicroWorld Technologies, have been compromised by unknown attackers. Legitimate updates were hijacked to distribute a persistent downloader and a multi-stage malware targeting enterprise systems and end-users. The official eScan infrastructure was used as an infection vector. No specific date or additional technical details (such as malware families or indicators of compromise) are mentioned.
