WikiLeaks dumped today the documentation of two CIA hacking tools codenamed BothanSpy and Gyrfalcon, both designed to steal SSH credentials from Windows and Linux systems, respectively.
Both tools are “implants,” a term the CIA uses to describe malware payloads. Once installed through various means on a target’s computer, these two implants hook into SSH-related processes and steal credentials or session traffic, where possible.
BothanSpy targets Windows
The first — BothanSpy — was designed for Windows computers. According to a 12-page manual dated in March 2015, the malware will hook into the process of Xshell, a Windows SSH client.
BothanSpy will use this access to steal user credentials for all active SSH sessions. This data can be sent right away to a remote server, or stored on disk in an encrypted file.
Gryfalcon targets Linux
The second — Gyrfalcon — is an implant for Linux systems. According to a 27-page manual dated in November 2013, this malware can target distros such as RHEL, Ubuntu, Suse, Debian, and CentOS.
Gryfalcon works by targeting the OpenSSH client, from where it can extract user credentials for active SSH sessions and full or partial OpenSSH session traffic. The stolen data is saved locally into an encrypted file, and is exfiltrated at a later date.
CIA operatives need root privileges to install Gryfalcon, but the tool itself can operate from a regular account.
