Quote:Security researchers from Zscaler have found a new remote access Trojan (RAT) for sale on the Dark Web that includes multiple functions and is able to spread via removable USB drives.
Dubbed Saefko, the backdoor remains in the background and executes every time a user logs in. The malware was designed to fetch Chrome browsing history for specific types of activities, send data to the command and control (C&C) server, and execute commands received from the C&C.
