CrydBrox

Also known asCrydBrox

CrydBrox is the handle of an underground actor associated with offering the AZORult information-stealing malware in criminal marketplaces. The provided content states AZORult was offered by CrydBrox after its discovery in mid-2016, and that in early 2017 CrydBrox advertised an updated variant, AZORult V2, with Namecoin ".bit" domain support. The advertisement for AZORult V2 claimed capabilities including theft of credit card data from Chrome-based browsers, password theft from WinSCP and Outlook, encrypted communication between the management panel and the stealer, and anti-analysis features including AntiVirtualMachine, AntiSandbox, and AntiDebug. The actor also advertised four payload variants: EXE, self-deleting EXE, DLL, and threaded DLL, with DLL versions stated to work with popular bots. The content further describes an AZORult sample that checks whether its C2 contains ".bit" and, if so, attempts resolution through hard-coded OpenNIC resolver IP addresses, consistent with the advertised .bit communications support. No additional aliases or sub-groups are provided in the content.
