Detects the execution of command-line tools (powershell, cmd, bash, curl, etc.) originating from common package managers and build tools (npm, node, pip, python, yarn). The rule flags these processes if they contain command-line arguments indicative of suspicious activity such as base64-encoded commands, remote script execution (IEX, curl/wget to shell), or indicators of persistence mechanisms (scheduled tasks, registry Run keys).

Detects a suspicious PowerShell process lineage spawned by explorer.exe that exhibits characteristics of a 'ClickFix' social engineering lure (using obfuscated command lines) and proceeds to inject code into legitimate Windows or browser processes such as csc.exe, chrome.exe, msedge.exe, or SearchIndexer.exe. This activity is often associated with malware attempting to evade debugging.

Detects the use of the built-in Windows 'cipher.exe' utility with the '/w' flag, which is used to securely overwrite free space on a disk, a technique often used by adversaries for anti-forensics or data destruction to prevent file recovery. The rule specifically alerts on execution from command-line environments (cmd.exe) where the command output is redirected to null, often used to hide the progress or output of the wiping process.

Detects the execution of diskpart.exe using a script file (via the /s parameter) where the parent process is not a standard system utility. This behavior is often indicative of attackers using diskpart to automate disk operations, such as clearing volume shadowing or modifying disk configurations, during post-exploitation activities.

001
This rule detects potential ransomware activity by correlating three distinct events: the execution of a suspicious, potentially obfuscated binary (matching a specific naming pattern of _win64.exe) from an untrusted location (e.g., Temp, AppData, Downloads), followed by a high volume of file modifications or renames with specific ransomware-related extensions (.locked), and the dropping of a known ransom note file (RESTORE_FILES.txt) within a short 15-minute time window.

This rule detects the presence, installation, or execution attempts of the known vulnerable GIGABYTE driver (gdrv.sys). Monitoring for this specific driver is a common practice to identify attempts to perform 'Bring Your Own Vulnerable Driver' (BYOVD) attacks, which can be used for kernel-mode code execution and privilege escalation.

This rule detects the use of specific tools associated with credential dumping and memory forensics, including Dokan driver installations for file system mounting, the use of DumpIt for creating memory dumps, and the subsequent analysis of these dumps using MemProcFS to access sensitive process memory information such as LSASS minidumps.

001
Detects instances where AI coding assistants or tools (e.g., Claude, Copilot, Gemini) invoke git.exe to clone or fetch repositories from non-standard (non-GitHub) hosts, followed by a checkout operation within a short timeframe. This behavior may indicate an attacker using automated tools to stage or exfiltrate sensitive code repositories to unauthorized infrastructure.

Detects the loading or execution of pkexec.so, which is indicative of exploitation attempts targeting CVE-2021-4034 (PwnKit). This vulnerability allows for local privilege escalation on Linux systems, including within compromised containers.

This rule detects potential exploitation activities targeting Atlassian Confluence by monitoring for unauthorized access to administrative configuration actions (e.g., setup/setupadministrator.action) and the subsequent addition of accounts to the 'confluence-administrators' group. It correlates process execution, network request patterns, and local user account modifications to identify successful or attempted privilege escalation and configuration manipulation.

Detects execution of processes masquerading as system threads (e.g., [kcached], [rcu_preempt]) that utilize the command-line flag 'exec -a' and include indicators associated with 'gs-dbus' or specific port configurations (GS_PORT=53). This pattern is often associated with obfuscated command-and-control or malicious persistence mechanisms that attempt to hide within common system process names.

Detects modifications or creations of files within the /var/spool/cron directory specifically involving the postgres user, as well as process execution of the 'crontab' utility by or for the postgres user. This activity may indicate an adversary attempting to establish persistence or execute code with postgres privileges.

This rule detects activities associated with suspicious credential dumping and lateral movement tool usage, specifically targeting 'DumpIt.exe' for memory dumping, 'dokan.exe' for potential driver installation, and the creation of known suspicious files like 'memfix.zip' or 'Server.raw'. These actions are commonly indicative of post-exploitation credential harvesting and preparation for exfiltration.

001
Detects anomalous activity originating from or associated with the PostgreSQL service account, including the execution of shells and utilities commonly used for post-exploitation or system enumeration, as well as external network logins. This activity is indicative of credential abuse or container escapes where an adversary attempts to execute commands on the underlying host.
