Detects Remote Desktop (RDP) logon events (LogonType 10) initiated by common privileged or service-oriented accounts such as administrator, backup_EA, or backup_DA. This behavior may indicate unauthorized remote access or credential abuse using highly privileged accounts.
Detects network connections from common browser processes and script execution engines to the known Payroll Pirate (Storm-2755 / Storm-2657) phishing domain 'bluegraintours.com', which is associated with Adversary-in-the-Middle (AiTM) session cookie and OAuth token harvesting.
Detects suspicious execution patterns originating from Gitea act_runner that indicate potential container escape attempts or host namespace manipulation. The rule flags the use of sensitive docker flags such as --pid=host, --ipc=host, --cap-add=ALL, and security profile unconfining, alongside the execution of 'nsenter' or the existence of specific proof-of-concept markers related to container escape vulnerabilities.
This rule detects potential Remote Code Execution (RCE) attempts leveraging Velocity Template Language (VTL) injection vulnerabilities within AWS API Gateway. It monitors logs for specific indicators, including references to 'ProcessBuilder', malicious template artifacts, and exploitation patterns associated with the 'floci-apigateway-vtl-rce-poc' exploit.
Detects the AdaptixC2 agent (AdgNsy.exe) performing process injection into the Windows Address Book (WAB.EXE). The rule specifically monitors for the creation of AdgNsy.exe, its execution under the WMI Provider Host (WmiPrvSE.exe), and subsequent cross-process access to WAB.EXE, which is a known behavior of the AdaptixC2 framework utilized during Akira ransomware intrusions.
Detects the modification of the 'UseLogonCredential' registry value within the WDigest configuration key to 1. Enabling this value forces Windows to cache user credentials in plaintext in the memory of the Local Security Authority Subsystem Service (LSASS), which is a common post-exploitation step to facilitate credential harvesting using tools like Mimikatz.
Detects the use of PowerShell to manually modify file system timestamps (CreationTime, LastWriteTime, LastAccessTime) on ASPX files or within common web-accessible directories. This technique is often used by adversaries to hide the true creation or modification time of webshells, facilitating anti-forensic activities and timeline corruption.
Detects suspicious child process creation originating from Adobe ColdFusion or IIS worker processes (w3wp.exe). This rule monitors for the execution of command-line shells, scripting engines, or download utilities often used in exploitation of vulnerabilities like CVE-2023-26360, CVE-2023-29298, or CVE-2023-29300.
Detects attempts to clear Windows Event Logs using common utilities including wevtutil, PowerShell (Clear-EventLog, EvtClearLog), or command-line wrappers. Clearing event logs is a common technique used by adversaries to disrupt incident response and cover their tracks after an intrusion.
Detects the use of appcmd.exe to disable HTTP logging for an IIS site by setting 'dontLog' to True. Adversaries may perform this action to evade detection and prevent security logging of their activities on a compromised web server.
