Cyber Command’s TrickBot Disruption Efforts are “Precedent-Setting”. US Cyber Command’s efforts to disrupt the TrickBot botnet mark “the first public, obvious operation to stop someone’s cyber capability before it could be used against us to cause even greater harm,” according to Columbia University cyber conflict researcher Jason Healey. Cyber Command severed communication between infected machines and the botnet’s command-and-control servers, and it injected nonsense data into the information TrickBot stole. While the efforts did not cause serious damage to the botnet, the action Cyber Command took “shows the growing reach of US military hackers.” Read more in: A Trickbot Assault Shows US Military Hackers’ Growing Reach

Microsoft Uses Trademark Law In An Attempt To Disrupt TrickBot Botnet

The TrickBot botnet has infected over a million servers and is used to spread ransomware, notably the Ryuk ransomware that has been infecting organizations like healthcare providers.

A court in Virginia has granted Microsoft permission to seize many of the operating control servers TrickBot uses to deploy malware, based on claims that they are abusing Microsoft’s trademarks. Microsoft argued that Trickbot irreparably harms the company “by damaging its reputation, brands, and customer goodwill.” As a result, they’ve taken over some of the servers, and shut them down.

Microsoft said that they don’t expect their action to permanently disrupt it, but they’re doing all they can to make the operator’s lives harder. The cybersecurity firm Intel 471 agreed, stating that “It is highly likely a takedown of the Trickbot infrastructure would have little medium- to long-term impact on the operation of Trickbot.” Refer to the legal filings from Microsoft here.
