This rule is designed to detect abnormal process behavior associated with Mozilla NSS-Mozglue libraries (mozglue.dll and nss3.dll), which could indicate potential security threats. The detection relies on Sysmon Event logs, specifically EventCode 7 that captures image loaded events. Loading these libraries outside of expected applications (Firefox, Thunderbird, etc.) raises a red flag about unauthorized access or manipulation. If this behavior is confirmed as malicious, it could lead to data exfiltration or credential theft, posing a significant risk to system integrity. The detection utilizes a specific search within Sysmon data to filter legitimate processes and highlight anomalies, thus aiding in identifying and mitigating risks effectively.
