Detects LCRYX ransomware performing UAC bypass by utilizing VBScript to spawn a new wscript.exe process with elevated privileges. The rule monitors for WScript or CScript processes spawning another WScript process where the command line contains the '/elevated' flag, indicating the use of the Shell.Application object's ShellExecute method with the 'runas' verb.
Detects the creation of files on web servers matching known Neo-reGeorg web shell tunnel variants. These files are typically used as backdoors to tunnel traffic and provide persistent access to the server.
This rule detects unauthorized configuration of GRE tunnels on Cisco IOS-XE network devices, potentially indicating persistent command and control (C2) channel establishment via TCL injection or illicit configuration changes involving known attacker infrastructure (62.171.185.97). It correlates network traffic to the attacker IP with process-level activity involving suspicious configuration files, scripts, or device-specific command-line arguments.
This rule detects the execution of scripts and commands associated with known SAP RFC exploitation attempts, including specific shell scripts used for RCE or credential extraction, as well as the invocation of SAP function modules like SXPG_CALL_SYSTEM for OS command execution. These patterns are consistent with post-exploitation activity or unauthorized system administration in SAP environments.
This rule detects the execution of known SMB exploitation tools (e.g., Python-based SMBGhost scanners/payloads, Metasploit resource scripts for EternalBlue) and identifies high-fan-out SMB scanning activity or unauthorized SMB connections from non-standard processes to an internal subnet (10.39.x.x).
This rule detects activities associated with CORS-based exploitation and session token harvesting, specifically targeting the creation or access of known exploit files (e.g., cors_exploit_poc.html) and the use of command-line tools (curl, wget, PowerShell) to interact with suspicious artifacts or session tokens (AMAUTHID/SAT).
Detects the execution of known Oracle database PII exfiltration scripts and patterns associated with the 'MexicanMafia Operation Escaneo' campaign. The rule monitors for specific command-line activity, including the use of extraction scripts like 'dump_oracle_pii.sh', 'fast_extract.py', and database-level exfiltration techniques such as UTL_FILE or sys_eval targeting incremental CSV exports to /tmp.
Detects host-level evidence of DRAYN malware activity by correlating outbound network connections using a specific websocket-sharp User-Agent to a known command-and-control (C2) IP address with the execution of PowerShell commands performing system UUID fingerprinting (Win32_ComputerSystem).
This rule detects activities associated with the DRAYN malware, specifically the unauthorized modification of Discretionary Access Control Lists (DACLs) on MSP management platform directory archives using icacls, followed by the creation of a scheduled task to establish persistence.
Detects non-browser processes accessing sensitive browser data files (such as Login Data, Cookies, or key stores) followed by network activity to known suspicious, cryptocurrency, or potential malware-hosting domains. This behavior is indicative of credential theft and exfiltration by information-stealing malware.
