The DanaBot malware has returned with a new version observed in attacks, six-months after law enforcement's Operation Endgame disrupted its activity in May.

Zscaler also identified and listed several cryptocurrency addresses that threat actors are using to receive stolen funds, in BTC, ETH, LTC, and TRX. DanaBot was first disclosed by Proofpoint researchers as a Delphi-based banking trojan delivered via email and malvertising. It operated under a malware-as-a-service (MaaS) model, being rented to cybercriminals for a subscription fee. In the years that followed, the malware evolved into a modular information stealer and loader, targeting credentials and cryptocurrency wallet data stored in web browsers. The malware was used in numerous campaigns, some of which were large-scale, and reappeared occasionally from 2021 onward, remaining a steady threat to internet users.
