The "Multiple Archive Files Http Post Traffic" detection rule is designed to identify potential data exfiltration attempts by monitoring high-frequency HTTP POST requests containing archive files. By analyzing the headers of HTTP stream logs for signatures of common archive formats, such as ZIP and RAR, this rule flags any instances where over 20 such requests originate from a single source IP. The detection leverages several metrics including the request body, user agent, and bytes transferred to accurately depict potential exfiltration events. Given that advanced persistent threats (APTs) or trojan spyware often utilize similar techniques to distribute collected data to malicious command and control (C2) servers, timely detection of such behaviors is critical for preventing serious data breaches. Implications of these activities can lead to unauthorized data leaks, and as such, monitoring and alerting can provide early warnings for security teams.
