This rule detects either the execution of a specific SSH daemon binary known to be trojanized or the creation/modification of files within the /var/lib/sshd/ directory, which is a common indicator of backdoor persistence or credential theft targeting SSH sessions.
Detects attempts to install or modify the 'WMI Provider Host' (WmiPrvSE) service, which is a common technique used by adversaries for persistence or to masquerade malicious activity. The rule monitors process execution, registry modifications, and service installation events specifically targeting this service name.

The rule monitors process execution, registry modifications, and service installation events specifically targeting this service name.
Detects instances where PowerShell is used to download an executable named 'svchost.exe' from an external IP address (103.86.86.244). The rule monitors for network connections to this IP, file creation events matching specific download patterns in fonts directories, and direct command-line arguments involving the suspicious IP and file path, indicating potential malware dropper activity.
Detects the use of the Windows reg.exe utility to copy Registry keys related to Radmin, a legitimate remote access tool that is frequently abused by threat actors for persistence and remote control. The command-line arguments /s and /f indicate a silent, forced copy operation, which is characteristic of script-based configuration tampering.
Detects the use of the native Windows registry utility 'reg.exe' to import configuration files (install.reg) related to the Radmin remote access software, specifically targeting the security settings registry path.

This rule detects potentially malicious PowerShell execution patterns involving hidden windows, administrative elevation via 'Start-Process -Verb RunAs', and the targeting or execution of rsetup64.exe within specific system paths. It also flags execution chains where 'net session' commands, often used for discovery or local privilege verification, are piped to null and followed by or initiate the same target executables, suggesting lateral movement or persistence attempts.
Detects instances where the Kaspersky antivirus process (avp.exe) spawns potentially malicious or administrative binaries like cmd.exe, powershell.exe, or specific artifacts related to 'HardBreacher'. This behavior is highly irregular as antivirus software typically does not initiate these types of processes under high-privilege tokens.
Detects anomalous system reconnaissance activity performed using WMIC or PowerShell Get-WmiObject commands. The rule tracks distinct command-line executions per device and flags hosts where three or more unique reconnaissance commands are executed within a short timeframe, which is indicative of an adversary enumerating system configuration, hotfixes, or hardware details.
Detects PEEP Secure Preferences integrity-hash forgery (protection.macs/super_mac) and known PEEP persistence scripts (patch_secure_prefs.ps1, install_silent.ps1, force_enable.ps1), anchored to actual Chrome/Edge profile paths rather than generic terms like 'protection' or 'developer_mode' that appear in unrelated admin tooling.
Detects Python processes executing common system and network enumeration tools (e.g., net.exe, tasklist.exe, dsquery, Get-ADUser). This activity is indicative of the SynkLoader system profiler module, used to size the victim environment for ransom-value estimation and lateral movement preparation.
Detects nm_host.exe (PEEP native messaging host binary) spawned by Chrome/Edge, tightened to require either the known PEEP extension ID in the native-messaging invocation command line or the distinctive com.peep.lab host path.
The following analytic detects the execution of `whoami.exe` without any arguments. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution logs. This activity is significant because both Red Teams and adversaries use `whoami.exe` to identify the current logged-in user, aiding in situational awareness and Active Directory discovery. If confirmed malicious, this behavior could indicate an attacker is gathering information to further compromise the system, potentially leading to privilege escalation or lateral movement within the network.
Detects the creation of a Linux named pipe (mkfifo) used in conjunction with netcat (nc) to establish a reverse shell connection to a specific C2 IP address or port 3090. This combination of commands is a common technique used by attackers to achieve remote command execution.

Detects the execution of known offensive security tools often used for lateral movement, credential dumping, and remote code execution, such as Impacket modules and the 'Invoke-TheHash' PowerShell suite, via common command-line interpreters.

Detects the execution of a Perl script 'package_info.pl' with specific arguments involving a temporary license file in '/var/tmp/'. This behavior is indicative of potential administrative tool abuse or unauthorized license manipulation/verification activity on Linux systems.
Detects the execution of a Perl script named 'package_info.pl' with specific command-line arguments involving 'license.tmp' located in '/var/tmp/'. This pattern may indicate the execution of unauthorized tools, license bypass attempts, or potentially malicious scripts masquerading as legitimate license management utilities.
