DanaBot, a well-known banking trojan and information stealer, has re-emerged with a new Windows variant (version 669) after a six-month hiatus following the law enforcement takedown known as Operation Endgame. Security researchers from Zscaler ThreatLabz and others have observed that the new version leverages both standard IP-based command-and-control (C2) domains and Tor (.onion) addresses, as well as "backconnect" nodes, to manage infections and deliver additional payloads. The updated malware exhibits increased modularity, allowing for remote payload management, infection parameter updates, and enhanced persistence, making it more difficult to detect and remove. Attackers are distributing DanaBot primarily through spear-phishing emails, malicious attachments, SEO poisoning, and malvertising campaigns, with the malware capable of harvesting credentials, cryptocurrency wallet data, and facilitating lateral movement within compromised networks.
The resurgence of DanaBot highlights the resilience of cybercriminal operations, as the core operators were not apprehended during the takedown, enabling them to rebuild infrastructure and resume activity. Researchers have identified new cryptocurrency wallet addresses used by the threat actors to receive stolen funds in BTC, ETH, LTC, and TRX. The malware continues to be offered as a malware-as-a-service (MaaS), rented out to other cybercriminals for use in various campaigns, including those that may lead to ransomware deployment. Organizations are advised to update their blocklists with the latest indicators of compromise (IoCs) and remain vigilant against evolving social engineering tactics used to deliver DanaBot.

3 events from the most recent confirmed update back to the earliest known activity.
Alongside its findings on the revived DanaBot activity, Zscaler shared indicators of compromise associated with the latest campaign. The published technical details included infrastructure and other artifacts intended to help defenders detect the malware's return.
By November 2025, Zscaler ThreatLabz reported that DanaBot had resurfaced in the threat landscape with a new Windows variant, version 669, after the post-Endgame lull. The researchers said the renewed campaign used newly identified command-and-control infrastructure and cryptocurrency wallet addresses linked to the operators.
In May 2025, the international law-enforcement Operation Endgame targeted initial-access malware operations, disrupting DanaBot activity along with multiple other malware families and resulting in arrest warrants. DanaBot activity then dropped for roughly six months following the action.

Proofpoint reported that **DanaBot**, a Delphi-based banking Trojan and stealer sold through a malware-as-a-service model, re-emerged with a fourth major version after activity dropped in mid-2020. The updated malware kept its modular design, hardcoded command-and-control infrastructure, **TOR** fallback, and a binary TCP protocol protected with **AES-256** and **RSA**, while continuing to support multiple affiliates. Researchers said recent infections were tied to software cracks and warez sites delivering a multi-stage bundle that included a credential stealer, a likely AutoIT cryptocurrency miner, and DanaBot; the stealer collected browser credentials, cookies, screenshots, system details, and potentially cryptocurrency wallet data. Earlier Proofpoint research showed DanaBot had already expanded from Australia into Europe and the United States through large affiliate-driven campaigns, including eFax-themed phishing that used malicious macro documents to install **Hancitor**, then fetch Pony stealer variants and DanaBot. Proofpoint also uncovered what it assessed to be the malware’s affiliate control panel, a graphical client tied to DanaBot through shared infrastructure, protocol overlap, and an embedded RSA public key, indicating a centralized global backend rather than fully separate affiliate infrastructure. The panel exposed extensive operator capabilities, including keylogging, webinjects, screen recording, file operations, screenshots, command execution, and remote access through **VNC** and **RDP**.

DanaBot, a malware-as-a-service platform used for credential theft, banking fraud, remote access, and data exfiltration, has remained active through both targeted intrusions and broad distribution campaigns. Researchers tied major software supply-chain compromises involving the `ua-parser-js` and `coa` NPM packages to DanaBot affiliate activity, where loaders and payloads were configured primarily for credential theft, while a separate affiliate used infected hosts to deliver a Delphi-based payload for HTTP DDoS attacks. Earlier reporting also documented a spearphishing campaign targeting personnel in an Australian government department, using a malicious VBS downloader and region-restricted delivery to install DanaBot from attacker-controlled infrastructure.

Researchers reported that **DanaBot**, long tracked as a banking Trojan, expanded its operations with new modules and delivery tactics that turned infected systems into platforms for broader criminal activity. ESET found the malware harvesting email addresses from compromised webmail sessions and, on some Open-Xchange services, sending reply-chain spam with malicious ZIP attachments from victims’ own accounts to spread additional payloads. The campaigns, including activity targeting Italy, showed DanaBot moving beyond credential theft and banking fraud into self-propagating spam operations, while infrastructure and payload patterns also suggested cooperation with other malware operators, including possible links to **GootKit**. Check Point later observed DanaBot campaigns delivering a Delphi-based ransomware strain dubbed **NonRansomware** through its modular command-and-control framework. In one European campaign, a `crypt` module fetched from `95.179.186.57` encrypted files with a `.non` extension, dropped **HowToBackFiles.txt** ransom notes, disabled defenses and recovery mechanisms, and created persistence with a scheduled task. The DanaBot platform itself was described as actively maintained, with updated plugins, revised string encryption and filename generation, and newer **AES256/RSA**-based C2 communications, underscoring its evolution from a banking Trojan into a multi-purpose malware service capable of spam distribution, payload delivery, and ransomware deployment.
