Silver Fox Deploys ABCDoor Malware via Tax-Themed Phishing in India and Russia

The threat actor group Silver Fox has launched a targeted phishing campaign against users in India and Russia, using fake tax-themed documents to deliver a new malware strain called ABCDoor. The sophisticated campaign exploits people's concerns about tax compliance to trick victims into opening malicious attachments that install the backdoor malware. Once deployed, ABCDoor gives attackers persistent remote access to compromised systems, allowing them to steal sensitive data and maintain long-term control of infected networks.
