Analysis Summary
The new fourth version of the DanaBot banking trojan has surfaced after months of inactivity. This most recent variant comes packed mostly with the same deadly arsenal of tools that have come before. Main features include a ToR component to anonymize communications between the bad guys and the infected hardware. As previously reported in the DanaBot control panel, DanaBot is set up as a ‘malware as a service in which one threat actor controls a global command and control (C&C) panel and infrastructure then sells access to other threats actors known as affiliates,”. DanaBot’s multi-stage infection chain starts with a dropper that triggers a cascading evolution of hacks. These include stealing network requests, siphoning off application and service credentials, data exfiltration of sensitive information, ransomware infection, desktop screenshot spying, and the dropping of a crypto miner to turn targeted PCs into cryptocurrency workers bees. At least one of the DanaBot distribution methods is identified as misuse of various software warez and cracks websites that supposedly offer software keys and cracks for a free download, including anti-virus programs, VPNs, graphics editors, document editors, and games. However, the files distributed by these sites are a bundle of several different malware, including DanaBot. Earlier Campaigns also distributed Danabot with new features.
