Detects the execution of the rdp2tcp tunneling tool in conjunction with RDP virtual channel activity using the 'rdp2tcp' channel name. This combination is a strong indicator of RDP-based protocol tunneling.

Detects PE executables whose embedded filename strings claim to be Adobe, TrueConf, or 1C software but whose PE metadata (company/product name) or digital signature does not match the claimed vendor, as used by NightEagle/GhostContainer operators to blend malicious tooling into normal process activity

Detects potential tampering with Windows Event Logs or audit services by correlating manual service stops or log clearing events (EventIDs 1100, 1102, 104, 7036, 7040) with a sudden, significant decrease in total event volume on the same host. The rule accounts for planned maintenance and legitimate event log service restarts to reduce noise.

Detection rules identifying malformed RDP MCS Connect Initial PDUs and unusual service crashes following RDP connection attempts, both indicative of exploitation attempts against the CVE-2019-0708 (BlueKeep) vulnerability.

Detects the execution of common discovery commands like 'whoami' combined with system information gathering commands (tasklist, ver, uname) when initiated by an application named 'pc-app.exe'. This pattern is frequently observed during the reconnaissance phase of an attack.

Detects the execution of BloodHound/SharpHound reconnaissance tools and the presence of their generated output files (ZIP or JSON format) on a host. This rule monitors both the process creation events associated with the tool's execution and file creation events indicative of data staging or collection output.

This rule monitors network traffic and internal logs for connections to known malicious IP addresses or domain names associated with 'ClickFix' social engineering campaigns (often impersonating services like HBO Max). The logic explicitly filters out known threat intelligence scanners and security researcher probes. It performs correlation by requiring domain/message matches for generic IP-based alerts to reduce noise, and aggregates events per host over 15-minute windows to produce consolidated alerts.
