This rule detects processes other than standard browsers (Chrome, Edge, Firefox, Opera) or authorized password managers (KeePass) accessing sensitive files such as browser credential stores, cookies, local state configuration files, KeePass databases (.kdbx), or VPN configuration files (.ovpn). The rule identifies suspicious activity by monitoring for access patterns that indicate potential credential theft or exfiltration.
Detects execution of PowerShell or PWSH containing multiple suspicious command line flags commonly associated with malicious scripts and evasion techniques, such as bypassing execution policies, running in hidden windows, using encoded commands, or utilizing invoke-expression.
Detects file creation events associated with the UAC-0226 campaign, specifically targeting Ukrainian military-themed lures and staging artifacts related to the GIFTEDCROOK malware. This rule monitors for the presence of specific file paths and naming conventions indicative of ongoing espionage operations.
Detects DNS TXT queries for the domain '_axiom-config.m100.cloud', which is associated with fileless payload retrieval techniques.
Detects suspicious DNS TXT record queries originating from common script interpreters (e.g., PowerShell, Python, Node.js) that are not recognized legitimate resolvers. The rule further correlates these DNS queries with subsequent process execution or network connection activity within a 60-second window, which is indicative of potential command and control (C2) communication or stager activity.
Detects Node.js processes ('node' or 'node.exe') spawning other processes or executing commands that reference suspicious file paths, such as '.libcache.so' or '.sh.local', or utilizing risky syscall patterns like 'memfd_create' or 'fexecve'. This pattern is often associated with malicious npm post-install scripts or supply chain attacks.
This rule detects when the node.exe process initiates an outbound network connection to a specific set of non-standard, often high-numbered ports (8443, 8445, 8453, 5555, 56001-56003) over the public internet. This behavior is often indicative of potential command and control (C2) communication, reverse shells, or malicious scripts executing within a Node.js runtime environment.
This rule detects various persistence mechanisms and configuration tampering techniques often associated with compromised development environments. Specifically, it monitors for the creation of LD_PRELOAD libraries in common directories, unauthorized modifications to shell profile scripts, suspicious cron job creation by Node/NPM processes, and the poisoning of configuration files for IDEs and AI coding assistants (e.g., Claude, Cursor, VSCode). It also detects the execution of suspicious Node.js scripts used as session hooks.

This rule detects activity associated with a known malicious campaign involving 'Photo ZIP' themed lures. It identifies DNS queries to actor-controlled domains, the spawning of PowerShell by Explorer.exe with command lines referencing photo-related filenames or external file-sharing services, and the subsequent downloading of the node.exe runtime to user-accessible directories (consistent with TonRAT delivery).
