Detects the PoisonedRefresh implant's UNIX domain socket backdoor by (1) file activity on the uniquely-named /run/bigtlog.pipe socket initiated by an Apache/httpd process, and (2) process command lines containing the implant's hardcoded authentication token. Removed the earlier generic 'bash spawned by httpd' heuristic, which fired on legitimate CGI/mod_php/admin automation that shells out from the web server and was the dominant false-positive source.
Detects unauthorized attempts to dump the process memory of the Local Security Authority Subsystem Service (LSASS), a common technique used by attackers to harvest credentials from memory. This includes the use of legitimate diagnostic tools like procdump and comsvcs.dll, as well as the identification of resulting dump files in directory paths associated with LSASS.
This rule detects suspicious file system activity (creation, modification, or renaming) performed by the ESET Remote Administrator (ERA) Agent process, excluding files within standard ESET installation and ProgramData directories. This behavior may indicate an adversary attempting to leverage the legitimate ERA agent to perform unauthorized file operations or masquerading as the agent.
Detects potential credential harvesting or process memory manipulation against browser processes (Chrome or Edge). The rule monitors for unauthorized debugging activity initiated against browser processes (e.g., using flags like DEBUG_PROCESS or specific API calls) and the access of the App-Bound encryption provider symbol, which is often a target for attackers seeking to decrypt browser-stored secrets.
Detects the execution of processes named 'ProManager.exe' or 'ProManagerServicedc894.exe', which may be indicative of unauthorized software or potentially malicious activity.
Detects the execution of an executable file located within the Windows Temp directory structure via the command prompt (cmd.exe). This pattern is commonly associated with the execution of downloaded payloads, droppers, or staged malware that are moved to temporary directories to evade initial detection.

Detects processes other than the official Telegram desktop client accessing sensitive local data files ('key_datas', 'settingss', 'usertag') within the Telegram application directory. This activity is often associated with credential theft or session hijacking.
Detects attempts to modify or disable the Windows Update service (wuauserv) using command-line utilities (sc.exe, cmd.exe, powershell.exe) in a context involving 'LockAppHost.exe'. This pattern is often associated with unauthorized attempts to tamper with security update mechanisms to prevent system patching.
