How Malicious Insiders Use Known Vulnerabilities Against Their Organizations

The text discusses the challenges and strategies related to insider threats in cybersecurity, as observed by CrowdStrike Intelligence between January 2021 and April 2023. Insider threats, defined as individuals with legitimate access inadvertently or deliberately causing harm to their organization’s IT systems, have increasingly exploited known vulnerabilities to achieve malicious objectives. CrowdStrike's analysis reveals that 55% of such incidents involved unauthorized privilege escalation, while 45% involved insiders unwittingly introducing risk by downloading offensive tools or exploits. Despite the difficulty in detecting these threats, the report suggests that many defensive measures effective against external cyber threats can also mitigate insider threats. The text emphasizes the importance of vulnerability management, user behavior analysis, and tailored training to prevent such incidents, highlighting the need for a comprehensive defense-in-depth approach and the importance of training employees to follow safe-handling procedures for exploits and offensive tools.
