Detects the Miasma worm kill chain triggered via binding.gyp during npm install. The attack
spawns node-gyp which executes a malicious index.js, downloads Bun runtime via curl, and
launches the payload with bun. A legitimate npm install should not spawn curl/unzip or
download alternative JavaScript runtimes.

Detects the arbitrary deletion of the critical WordPress configuration file (wp-config.php), which is a known impact of PHP object injection attacks (e.g., CVE-2025-7384) aiming to cause a denial of service.
This rule detects the creation of common ransomware ransom note filenames on a device. It triggers when two or more distinct ransom note files are created within a 5-minute window, indicating potential ransomware activity.
Detects the execution of the GitHub CLI command used to print the active authentication token, which is abused by the Shai-Hulud worm to steal developer credentials.
Detects the destructive command line used by the Miasma campaign's dead man's switch to wipe the user's home directory upon token revocation. Specifically looks for 'rm -rf ~/; rm -rf ~/Documents' executed by 'rm' or 'rm.exe'.
This rule detects outbound network connections from devices to IP addresses identified as malicious by a threat intelligence feed. It joins device network events with threat intelligence indicators, specifically looking for successful connections or connection requests to IPs with a confidence score greater than 50. The alert provides details about the device, the remote IP, the initiating process, and the threat intelligence context.
This rule detects an attempt to escalate privileges on a system via SSH by looking for the string "sudo su" within an established TCP connection to port 22 (SSH). This indicates a user is trying to switch to the root user or another user with elevated privileges using the sudo command.
This rule detects unauthenticated access attempts to the Docker Daemon API, specifically targeting TCP port 2375. It triggers on the initial SYN packet of a TCP connection to this port, indicating an attempt to establish a connection to the Docker API without authentication. This activity is often associated with privilege escalation attempts, as an unauthenticated Docker API can be exploited to gain control over the host system.
This rule detects attempts to enumerate Linux system logs via remote SSH connections. Specifically, it looks for the string "cat /var/log/" within TCP traffic on port 22 (SSH). A threshold of 10 occurrences within 30 seconds from the same source IP is set to reduce false positives.
This rule set detects various stages of the JFMBackdoor and Showboat malware, including DLL sideloading of FLTLIB.dll by fltMC.exe from non-standard directories, network connections to known C2 and staging infrastructure (namefuture.site or 23.27.201.160), command-line activity referencing a specific Pastebin URL used by Showboat for process-hiding code, and the creation of JFMBackdoor payload artifacts (flt.bin, scr.mui).
Detects process executions or command-line arguments referencing the installation of identified malicious npm packages, specifically 'chalk-tempalte', '@deadcode09284814/axios-util', 'axois-utils', and 'color-style-utils'. These packages are associated with 'Shai-Hulud clones' and 'Phantom Bot' campaigns, often involving typosquatting or similar deceptive naming conventions to trick developers into installing malicious dependencies.
This rule detects attempts to install a kernel module (rootkit) on a Linux system via an SSH session. It specifically looks for the 'insmod' command followed by a '.ko' file extension within TCP traffic destined for port 22 (SSH). This combination suggests an attacker is trying to load a malicious kernel object.
This rule detects the string "setfattr" in TCP traffic destined for port 22 (SSH). The presence of "setfattr" in SSH traffic might indicate an attempt to use Linux extended attributes to hide data or malicious payloads, a technique often associated with defense evasion.
This rule detects the string "mount --bind" within TCP traffic on port 22 (SSH). This string indicates an attempt to create a bind mount, which can be used by attackers to obscure the true location of malicious files or to manipulate file system access. The rule specifically looks for this activity on the home network, suggesting an internal system being targeted or used for malicious purposes.
Detects network connections attempting to download the specific Bun v1.3.13 archive from the oven-sh GitHub repository, which is used by the stage 3 bootstrapper in the Miasma npm malware campaign.
Detects network connections from Bun or Node.js processes to GitHub API endpoints
used by the Miasma worm for credential exfiltration. The malware creates repos under
the liuende501 account and uploads encrypted stolen credentials.

Detects attempts to read Runner.Worker process memory to extract GitHub Actions secrets
in their unmasked form. The Miasma worm uses sudo python3 to escalate privileges and
read /proc/<PID>/mem, then pipes through grep to extract secret values.

Detects the execution of known VerdantBamboo payload names (luserput, ovs-dbctl, egnyte_host_monitor_client) or specific malicious deployment paths, indicating potential PLENET, BRICKSTORM, or AGENTPSD malware activity on compromised Linux and edge devices.
Detects instances where node or Electron processes are executed with the ELECTRON_RUN_AS_NODE environment variable set to 1. This technique is used by UNK_DeadDrop to turn an editor into a plain Node.js interpreter for stealthy payload execution.
Scripting Interpreter Exec
Cortex XDR
This rule detects suspicious command execution patterns on Linux systems involving scripting interpreters. Specifically, it looks for these interpreters being invoked with command-line arguments that suggest direct execution of code. This pattern is commonly associated with web shell activity, reverse shells, or other forms of arbitrary code execution.
Detects attempts to read common HashiCorp Vault token paths from the filesystem, indicating potential credential harvesting by the Miasma stealer or other unauthorized access.
