Detects Kerberos TGT or TGS requests that either exhibit a suspicious combination of ticket flags (Forwardable + Proxiable + Renewable) when associated with high-value targets, unusual accounts, or off-hours activity, or utilize the weak RC4-HMAC encryption type, both of which are indicative of ticket manipulation and credential theft.

Detects anomalous administrative activity within Microsoft Exchange by identifying accounts performing multiple suspicious operations within a short timeframe. This rule flags activities like modifying transport rules, virtual directories, or management role assignments, which are often indicative of malicious persistence or configuration tampering, while excluding known authorized service accounts.
Detects the use of netsh.exe to establish a port proxy, specifically conditioned on the execution context of the Impacket atexec tool (indicated by specific naming patterns and parent processes). This activity often follows the lateral movement or execution of a remote service by a tool like Impacket.

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
