ZXShell

aka: Sensocode

Actor(s): APT41, Emissary Panda, Leviathan


According to FireEye, ZXSHELL is a backdoor that can be downloaded from the internet, particularly Chinese hacker websites. The backdoor can launch port scans, run a keylogger, capture screenshots, set up an HTTP or SOCKS proxy, launch a reverse command shell, cause SYN floods, and transfer/delete/run files. The publicly available version of the tool provides a graphical user interface that malicious actors can use to interact with victim backdoors. Simplified Chinese is the language used for the bundled ZXSHELL documentation.
