Detects execution of 'transformers.pyz', a zipped Python payload associated with the Miasma toolkit, by monitoring process creation events for command lines containing both 'python' and 'transformers.pyz'.
Detects the execution of the Chisel client establishing a reverse SOCKS tunnel with authentication. This activity is often associated with adversaries using Chisel for command and control or data exfiltration.
Detects process command lines that contain patterns indicative of obfuscated payload execution, specifically the combination of 'eval', 'base64', and '-d'. This technique is frequently used by adversaries to decode and execute memory-resident stages without dropping secondary payloads to disk.
Detects PowerShell downloading payloads from cdn.jsdelivr.net, which has been associated with malware like ClearFake.
Detects Node.js or Bun executing specific hidden setup files indicative of the Miasma payload being triggered by IDE configuration files (Cursor, Claude, Gemini, VSCode). This rule looks for process execution where the filename is 'node.exe', 'node', 'bun.exe', 'bun', or common shells ('cmd.exe', 'powershell.exe', 'pwsh.exe', 'bash', 'sh', 'zsh') and the command line contains specific Miasma payload patterns like '.github/setup.js', '.claude/setup.mjs', or 'bun run' with '.config/index.js'.
This rule detects the execution of Node.js processes that include specific attacker IP addresses (23.254.164.123:443 or 23.254.164.92:8000) in their command line arguments, combined with the creation of a file named '.pkg_logs'. This behavior is indicative of the Mastra NPM supply chain attack, where malicious packages drop a logging file after execution.
Detects bulk scraping of LinkedIn company profiles for employee intelligence
Detects the execution of the 'moladb_superusers.py' script, which is associated with the MuddyWater threat group for database enumeration.
Detects modifications to the VSCode tasks.json configuration file by processes other than the VSCode editor itself. This activity can indicate an attempt to establish persistence or execute malicious code, as seen with malware like Miasma which alters this file to run malicious code during local builds.
This rule identifies processes establishing synchronization objects (mutexes) that start with the hardcoded prefix 'Global\EVOLUTION'. This pattern is indicative of the EVOLUTION stealer malware execution, as it uses this specific mutex naming convention to ensure only one instance of itself is running.
Detects the execution of 'tanstack_runner.js', which is identified as a specific payload dropped during a compromised tanstack npm supply chain incident linked to Miasma. The rule looks for command-line executions involving 'node' or 'bun run' with 'tanstack_runner.js'.
This rule detects when a single process account initiates a high volume (10 or more) of file move operations to folders associated with cloud storage services (e.g., 'cloud', 'dropbox', 'drive') within a one-hour window. This behavior could indicate data exfiltration or staging for exfiltration.

Detects bulk scraping of LinkedIn company profiles for employee intelligence
This rule detects network connections from devices to a predefined list of known malicious domains. It identifies attempts by internal systems to communicate with command and control servers, phishing sites, or other infrastructure associated with threat actors.
Detects the execution of nested, hidden, and bypassed PowerShell sessions spawned by cmd.exe, typically launched from a Startup LNK file. This behavior is associated with the SHADOW-EARTH-066 campaign, which uses specific command-line arguments for evasion and loads payloads from C:\ProgramData\ using Invoke-Expression or iex.
Monitors for network connections originating from the VSCode extension host process to GitHub API endpoints immediately following a new extension installation. This may indicate token exfiltration or repository enumeration from a malicious extension.
Detects potential WordPress malware activity that abuses Steam Community profile comments as a command-and-control (C2) channel. The malware retrieves encoded payloads hidden in Steam profile comments using invisible Unicode characters, decodes malicious URLs, and downloads additional JavaScript payloads. This rule identifies outbound connections from WordPress servers to Steam Community URLs or known malicious infrastructure associated with this campaign.
Detects download of malware builder or generator tools from code repositories
Detects IP geolocation lookups used to determine system geographic location
Detects the creation or execution of the SSH propagation payload script (.sshu-setup.js), used by the Hades stealer to propagate via SSH from compromised workstations. This rule identifies file creation/modification/renaming events for the specific script name, or process creation events where the command line references the script.
