Detects the Iron Man System phishing kit via its HTTP fingerprint: a request-header rule (ETag/Server/Via combo) checked on the external server's response, and three request-side rules checking for the kit's hashed asset paths and favicon when an internal host requests them from an external site. Fixed a direction bug on the three request-side rules that had source/destination reversed (they previously required an external host to request the path from an internal server, which would rarely if ever fire).
Detects successful VPN authentication attempts originating from known Cloudflare WARP tunnel infrastructure or European VPS provider IP address ranges. This pattern is often used by adversaries to mask their true geographic origin or bypass location-based security policies.
This rule identifies potentially compromised Entra ID accounts by correlating multiple suspicious behaviors within a 14-day window. It aggregates four specific indicators: successful authentication following repeated MFA failures, impossible travel (sign-ins from multiple countries within a short timeframe), unusual hour logons (00:00-05:00), and sign-ins flagged with medium/high risk or reported as compromised. The rule triggers when an account exhibits two or more of these distinct anomalous behaviors.
Detects suspicious DLL loads or file drops performed by security product processes (avp.exe, MsMpEng.exe) from directories outside of standard, trusted vendor paths. It specifically flags unsigned or invalidly signed DLLs, which is indicative of DLL sideloading techniques used to abuse security software workflows for potential privilege escalation.
This rule detects potential ransomware activity by correlating risky user identity events (such as impossible travel or malicious IP access) with subsequent endpoint behavior typical of ransomware, specifically the deletion of shadow copies or system backups, or mass file modification activity occurring within a short window.
Detects anomalous remote interactive or network logons where the specific account and remote host/IP combination has not been observed in the previous 14 days. The rule correlates these new login events with subsequent process execution on the destination host within a short window (5 minutes) to identify potential lateral movement where an adversary uses valid credentials to log in and immediately execute commands.
Detects Koktevrat Stage 2 Android RAT component (com.kowo.ciligeci) that unpacks the RC4-encrypted uoN.css/uoN.apk payload using the RC4 key iOZ
Detects Koktevrat Stage 1 dropper (femam.apk / MandatGO) that decrypts and installs the encrypted wudEMR.apk secondary payload using a 3-byte XOR key

Detects multiple successful GitLab authentication events from a specific source IP that contain parameters indicating an attempt to skip or bypass two-factor authentication, consistent with known GitLab 2FA bypass vulnerabilities.
Detects successful remote logons to network devices (routers, VPNs, NAS) using the 'admin' account. This pattern is indicative of credential spraying or brute-force attacks targeting weak default credentials on externally facing management interfaces, often associated with botnets or threat actors performing reconnaissance and initial access operations.

Detects RedTail malware samples: UPX-packed, statically linked ELF executables across multiple architectures (x86_64, ARM, ARM64, i686, RISC-V). Requires UPX packing signature to co-occur with RedTail-specific filename strings to reduce false positives on generic UPX-packed binaries.
This rule detects potential tampering with the Huorong security product by monitoring for specific process names (HipsTray.exe, HipsMain.exe, HipsDaemon.exe, wsctrlsvc.exe, TrafficProt.exe) interacting with suspicious API calls or command lines indicative of token privilege manipulation, service blinding, or security product disabling/downgrade.
This rule detects the presence or execution of a file named 'GlobalProtect.exe' within the Palo Alto GlobalProtect directory. It focuses on identifying potentially masqueraded or unauthorized binaries by monitoring file events and associated process execution. This pattern is commonly used by attackers to disguise malicious files as legitimate security software to evade detection.
Detects the use of the MinHook library to hook CreateThread and spoof the thread start address as AnimateWindow, a technique used by the SparroWocky malware to conceal its true thread origin from security monitoring tools.
Detects PowerShell or PowerShell ISE spawned directly from Windows Explorer (explorer.exe, covering both Start-menu launches and the Run dialog abused by ClickFix) whose command line carries a genuine obfuscation/evasion signal - true -EncodedCommand/-e usage, a hidden/minimized window flag, or a remote download cradle (IEX, Invoke-WebRequest, DownloadString, certutil, mshta, etc.) - while excluding invocations that point at an on-disk script file under a standard install path, since ClickFix payloads are inline one-liners rather than references to a local .ps1. Bare -NoProfile/-NoLogo flags no longer trigger alone, since they are common in legitimate automation.

Detects rapid, sequential identity-validation API calls (such as GetCallerIdentity, GetSessionToken, or AssumeRole) performed across a large number of distinct AWS access keys from a single source within a short time window. This pattern is indicative of automated tooling validating a harvested corpus of AWS access keys to identify active credentials.
