The blog post from CrowdStrike provides an in-depth analysis of wiper malware, a type of destructive software designed to erase user data beyond recoverability, often used by threat actors to cause disruption or cover traces of an intrusion. The post outlines various techniques employed by wipers, such as targeting specific files or entire disks, and compares these methods to ransomware, highlighting that wipers are designed to irreversibly destroy data rather than demand ransom for its recovery. The text also discusses the evolution and resurgence of wipers, citing historical incidents and detailing the technical methods used to overwrite or delete data, including the use of APIs for file manipulation, and strategies for disk destruction to increase operation speed and effectiveness. Additionally, the blog emphasizes the importance of advanced detection and protection mechanisms, like those offered by the CrowdStrike Falcon® platform, which employs machine learning and behavior-based detection to mitigate such threats.
