Dark Reading is reporting on a new banking trojan called ‘Silence’ that mimics techniques similar to the Carbanak hacker group targeting banks and financial institutions. The attack vector is similar – target individuals using spear-phish emails to trick them into running a malicious attachment which will connect to download a dropper to further infect the user’s machine. This attack does not use an exploit against a vulnerability, but rather takes advantage of social engineering to fool the user into executing the malicious payload and infecting their machine.
Silence is interesting in that the trojan’s capabilities include a screen grabber that will take multiple screenshots of the user’s active monitor and upload the real-time stream to a command and control server for monitoring by the adversary. This technique allows the threat actor to identify which users have access to specific banking applications, systems, and accounts that they can use for financial gain.
