Two malware targeting Mac-run machines recently surfaced in the wild: Snake (a.k.a. Turla, Uroburos, and Agent.BTZ, and detected by Trend Micro as OSX_TURLA.A) and Proton (OSX_PROTON.A). Both are remote access Trojans that can grant attackers unauthorized remote access to the system, consequently enabling them to steal files, data, and credentials stored in the affected system, view the computer’s screen in real time, and log key strokes.
