On August 29, 2023, the FBI and the Justice Department announced a multinational operation, “Operation Duck Hunt,” to disrupt and dismantle Qakbot. The action occurred in the United States, France, Germany, the Netherlands, the United Kingdom, Romania and Latvia. Here’s what you need to know.
Qakbot, also recognized as “Qbot,” stands out as a potent weapon wielded by a sophisticated cybercriminal syndicate, demonstrating a global reach aimed at disrupting critical industries. The modus operandi of Qakbot revolves around leveraging deceptive email campaigns, wherein malevolent attachments or hyperlinks serve as the gateway for intrusion into unsuspecting systems. These compromised machines are orchestrated into a colossal botnet (which is a network of compromised computers), affording the threat actors centralized authority over their actions, all while maintaining a discreet distance from their unwitting hosts.
The FBI gained access to the Qakbot infrastructure and disrupted the botnet by redirecting its traffic to Bureau-controlled servers that instructed infected computers to download an uninstaller file. This uninstaller released infected computers from the botnet and prevented the installation of any additional malware.
According to the FBI, there were over 700,000 infected computers worldwide—including approximately 200,000 located in the U.S. The effort to take down the botnet system also seized nearly $9 million in cryptocurrency that was collected in criminal ransomware campaigns.

Organizations must remain vigilant to detect any potential presence of Qakbot within their systems. It’s crucial to maintain a high level of awareness concerning suspicious emails that might serve as the gateway for intrusion.
In a constantly evolving threat landscape, these proactive measures become the cornerstone of safeguarding sensitive digital assets from the pervasive menace of Qakbot and other cyber threats.
