JsonCookies

JsonCookies is a simple tool used by the Cycldek hackers, an Advanced Persistent Threat actor that is believed to be located in China. JsonCookies is one of the more basic utilities in Cycldek's arsenal, but it serves a very important purpose – it is able to extract cookies from the SQLite databases that Google Chrome and Chromium-based Web browsers use.

The JsonCookies implant does not look for a particular cookie type and, instead, it dumps the whole databases by listing the ID, cookie name, cookie value, and the domain name that these values correspond to. All of the data is stored in a file 'FuckCookies.txt' that is exported to the Command and Control server as soon as the attack is completed.

This is a proprietary tool whose author did not mean to be used for harmful purposes. However, cybercriminals adapt and modify such projects to fit their nefarious needs frequently.
