Hackers are distributing the MEDUZASTEALER malware via Telegram, posing as Reserve+ technical support from the Ministry of Defense of Ukraine.
The Cyber Emergency Response Team of Ukraine (CERT-UA) has issued an alert regarding spoofed phishing attacks that distribute MEDUZASTEALER.
The malware is being spread through suspicious messages prompting users to install 'special software' and containing an archive named 'RESERVPLUS.zip'.
Once executed, the malware exfiltrates files with specific extensions and deletes itself to bypass security software.
