Detects rapid termination of specific mobile messenger applications (Max) within seconds of starting, while indicators of the Frida dynamic instrumentation tool are concurrently detected on the device. This pattern suggests the application is identifying the presence of a hooking/instrumentation environment and self-terminating as a defense mechanism. The detection is further correlated with failed connection attempts to the application's backend.

This rule detects potential exploitation attempts targeting vulnerabilities within the libheif image processing library. It monitors for image processing binaries (e.g., convert, magick) executing with command-line arguments related to HEIF/HEIC files, followed by multiple application crash events (SIGSEGV, coredumps) associated with libheif on the same device within a short time window.
Detects a suspected exploitation attempt of CVE-2026-81000, known as TUNderflow. The detection looks for a sequence of events where a process initializes a user namespace (unshare) followed by a kernel panic or error report from the tun/tap driver originating from the same process lineage within a short timeframe, which is indicative of an integer overflow exploit leading to kernel instability.
Detects anomalous activity on WatchGuard Firebox VPN services, specifically monitoring for frequent daemon restarts or crashes (indicating potential RCE attempts) and high-volume bursts of IKE/ISAKMP negotiation failures (potentially indicating malformed packet attacks).
Detects unexpected crashes or restarts of the Windows Defender service (MsMpEng.exe) occurring in temporal proximity to activities associated with the ShieldCrash PoC or tampering within the Windows Defender object manager namespace. This rule aims to identify potential exploitation attempts targeting Windows Defender, specifically correlating security service instability with known malicious indicators.

This rule detects kernel crash signatures (e.g., use-after-free, kernel panic) in the pppoe module, correlated with preceding anomalous activity related to PPPoEject or PPPoE socket manipulation. It identifies potential exploitation of CVE-2026-68121 on non-gateway devices.
Detects a suspected exploitation attempt of CVE-2026-81000, known as TUNderflow. The detection looks for a sequence of events where a process initializes a user namespace (unshare) followed by a kernel panic or error report from the tun/tap driver originating from the same process lineage within a short timeframe, which is indicative of an integer overflow exploit leading to kernel instability.
This rule detects kernel-level stability issues or crashes (ah6/ipsec related) occurring immediately after the execution of processes that create new user namespaces (unshare, clone with CLONE_NEWUSER). This pattern is often associated with exploitation of kernel vulnerabilities, where namespace manipulation is a prerequisite for triggering a crash or privilege escalation.
