	"plain_text": "Threat Group Cards: A Threat Actor Encyclopedia\r\nArchived: 2026-04-02 12:03:22 UTC\r\nDescription(Trend Micro) There’s a new player in the card theft game that changes it altogether: Gorynych or the\r\nDiamond Fox botnet malware. BKDR_GORYNYCH may not technically be considered a PoS malware, as it is\r\nnot entirely designed for PoS systems and is also being used outside of the Black Atlas operation. However,\r\ncybercriminals running Black Atlas have built a copy that can specifically look for the output file of the BlackPOS\r\nmalware, which is the one that harvested the credit card data from the targets in the first place. The fact that the\r\nimages in Gorynych’s control panel were named “Kartoxa,” which also refers to BlackPoS, further proves the link\r\nbetween the two malware and the operation.\r\nAside from the PoS plugin, other modules usually downloaded from a subdirectory in the C\u0026C server make up\r\nthis malware’s entirety. These include plugins for getting screenshots, passwords, mails, and more. Without the\r\nplugins, Gorynych routines mostly focus on anti-analysis, information theft, and installations. In the Diamond Fox\r\nbuilder, the keylogger and PoS grabber functionalities are disabled by default. However, with Operation Black\r\nAtlas, these options were turned on, which proves that cybercriminals running this are intentionally targeting PoS\r\nsystems.\r\nAfter downloading its plugins, Gorynych reports to its server via gate.php using HTTP POST. It uses its own user-agent that can be found in its configuration file. The parameters consist of system information used to profile the\r\nbot, mainly for identification in the Gorynych control panel. The posted information is encrypted using a simple\r\nXOR operation.\r\nSource: https://apt.etda.or.th/cgi-bin/listgroups.cgi?u=a6bf48fd-e90c-40e9-8d54-5b41f3acaf0d\r\nhttps://apt.etda.or.th/cgi-bin/listgroups.cgi?u=a6bf48fd-e90c-40e9-8d54-5b41f3acaf0d\r\nPage 1 of 1",
