Technical Details

Janicab.A is written in Python and is capable of running on machines with either the Windows or OS X operating systems.

When executed, the malware displays a decoy document; in the meantime, it installs itself in the background and connects to a remote site in order to get the address of its command and control (C&C) server.

While active, the malware continuously uses a third-party plugin to take screenshots and record audio, then uploads these to the C&C server. It also constantly checks for additional commands to execute from the C&C server.

The malware is notable for being signed with an Apple Developer ID and for using the right-to-left override (RLO) feature of the bi-directional text encoding system to hide the real extensions of executable files.
