Detects potential lateral movement by identifying NTLM authentication (Logon Type 3) to administrative network shares (ADMIN$, C$, IPC$) or high-frequency access to multiple hosts by the same user, which may indicate credential abuse or lateral movement attempts.
This rule detects instances of Kerberos Ticket-Granting Ticket (TGT) requests (Event IDs 4768 and 4769) that utilize the legacy RC4 encryption type (0x17). In modern Active Directory environments where AES is the standard for Kerberos, the use of RC4 can be a strong indicator of a Golden Ticket attack or other unauthorized ticket forging activities, as adversaries often force a downgrade to RC4 for easier offline cracking.
Detects Microsoft Windows Event ID 4662 (Object Access) where specific GUIDs associated with sensitive Active Directory rights (specifically, those related to DCSync or sensitive extended rights) are accessed. The rule filters out events originating from Domain Controllers to identify potentially anomalous access patterns from non-DC endpoints.
Detects the loading of common Windows system DLLs (e.g., version.dll, dbghelp.dll) from suspicious, non-standard directory paths. Such behavior is often indicative of DLL side-loading or hijacking attempts, where an adversary places a malicious DLL with the same name as a legitimate one in a writable directory to influence application execution.
Detects the use of native Windows binaries such as vssadmin.exe, wmic.exe, bcdedit.exe, and wbadmin.exe to inhibit system recovery by deleting shadow copies, clearing backup catalogs, or disabling automatic system recovery.
Detects the use of BITSAdmin or PowerShell 'Start-BitsTransfer' to download files from non-reputable/non-Microsoft sources to suspicious directories such as Temp, AppData, or ProgramData, which is a common technique for ingress tool transfer during malware delivery.

Detects suspicious activity associated with Cobalt Strike Beacon communication, specifically monitoring for known default named pipes and specific user-agent strings commonly used by Cobalt Strike in HTTP/S traffic.
Detects the initiation of a new process where the effective user context is SYSTEM, but the originating process was launched by a non-privileged user account. This behavior is indicative of token manipulation techniques such as token impersonation or theft (e.g., via DuplicateTokenEx or ImpersonateLoggedOnUser) to escalate privileges to SYSTEM.
Detects AWS CloudTrail and Azure Active Directory (Entra ID) privilege-escalation actions (e.g., attaching policies, creating access keys, adding roles) performed by principals from rare source IPs or associated with low-frequency administrative actions, indicating potentially compromised or unauthorized account activity.
