CrowdStrike's report highlights the evolving tactics of eCrime adversaries in leveraging Microsoft OneNote documents to deliver malicious payloads, with a significant increase in such activities observed since early 2023. They detail how adversaries initially exploited Microsoft Office macro vulnerabilities before adapting to use OneNote files embedded with HTML Application (.HTA), Command (.CMD), and JavaScript Encoded (.JSE) files. These files execute embedded scripts to download second-stage payloads like QakBot, known for delivering additional malware such as Cobalt Strike. Despite Microsoft's efforts to patch vulnerabilities, adversaries continue to find new ways to achieve code execution, prompting CrowdStrike to recommend network defenders to baseline OneNote usage, block suspicious file types, and install endpoint detection systems like CrowdStrike Falcon. The report underscores the need for continuous adaptation and vigilance in cybersecurity practices to counteract the innovative tactics employed by threat actors.
