In a major win for international cyber defense, U.S. authorities — with support from cybersecurity firm CrowdStrike — have dismantled DanaBot, a Russia-based malware platform that operated as both a criminal enterprise and a strategic weapon in support of Kremlin interests. The takedown highlights the growing nexus between Russian eCrime groups and state-aligned cyber operations.
Botnet Neutralized: U.S. Seizes DanaBot’s Control Infrastructure
WASHINGTON, D.C. — The U.S. Department of Justice, in collaboration with the Defense Criminal Investigative Service (DCIS) and cybersecurity company CrowdStrike, has successfully dismantled the U.S.-based command-and-control infrastructure of DanaBot, a notorious malware-as-a-service (MaaS) platform operated by the Russian-linked eCrime group SCULLY SPIDER.
The seizure effectively neutralized DanaBot’s ability to issue commands to compromised systems, halting operations that had targeted financial institutions, corporations, and even national security agencies. The botnet’s infrastructure allowed it to steal credentials, exfiltrate cryptocurrency wallets, log keystrokes, and deliver other malware — functionality that was enhanced over several years since its emergence in 2018.
“This takedown represents more than the disruption of a financially motivated cybercriminal group. It disarms a tool that has served both criminal actors and Russian state objectives,” said Christy Brady, speaking on behalf of the City of Philadelphia, which has experienced similar cyber fraud threats.

Criminals or Proxies? Evidence Points to Russian State Alignment
Though DanaBot initially emerged as a sophisticated banking trojan, CrowdStrike’s threat intelligence and DOJ investigations uncovered disturbing overlaps with state activity. Notably, after Russia’s 2022 invasion of Ukraine, DanaBot’s infrastructure was used in targeted DDoS attacks against Ukrainian defense institutions.
CrowdStrike tracked DanaBot’s “sub-botnet 5” delivering a payload designed for HTTP-based DDoS against the Ukrainian Ministry of Defence and National Security and Defense Council, demonstrating how a criminal tool can be repurposed for military disruption.
Even more damning: two sub-botnets (24 and 25) were used for espionage, marking a transition from financial crime to intelligence gathering. While the full scope of data harvested remains unknown, it strengthens suspicions that SCULLY SPIDER was operating under Russian government protection — if not direction.
This blurring of lines between cybercrime and geopolitical objectives underscores what experts have long warned: that Russia’s hybrid cyber warfare strategy increasingly outsources operations to criminal groups, allowing plausible deniability while maximizing disruption.
The Bigger Picture: Public-Private Partnerships Crucial in Cyber Defense
The DanaBot takedown is a model case in cross-sector collaboration. CrowdStrike’s technical assistance helped U.S. authorities understand the malware’s evolution, identify its control nodes, and trace its use in supply chain attacks such as the compromise of NPM packages like ua-parser-js and coa — widely downloaded tools used in web development that were leveraged to distribute DanaBot and cryptocurrency miner XMRig.
Between 2018 and 2021, DanaBot had evolved from a banking trojan to a modular cyber weapon used in ransomware, fraud, and politically motivated attacks. Its continued code refactoring and pricing adjustments since 2022 illustrate how SCULLY SPIDER adapted to market demand and political imperatives alike.
As of this week, several Russian nationals have been indicted for developing and deploying the malware, though prosecution is unlikely unless extradition becomes feasible. Still, this symbolic and technical victory cuts deep into one of Russia’s most potent cyber proxies.
