New QakBot phishing campaign appears, months after FBI takedown

Months after an FBI-led takedown of the QakBot botnet, a new phishing campaign distributing the same malware has been discovered. Microsoft’s Threat Intelligence team identified the campaign, which targeted the hospitality industry and sent phishing emails posing as the U.S. Internal Revenue Service. Despite the botnet’s disruption in August, there were no arrests, hinting at a possibility of the perpetrators regrouping.
