This rule detects process command line arguments that include the string 'data.external.telemetry', which may indicate the use of specialized tools, telemetry collection agents, or unauthorized data exfiltration channels.
Detects the creation of tar archives within the Coder database during a specific window associated with rogue IP activity, where the file creation was performed by a system-level process.

Detects the presence of a specific sentinel string 'data.external.telemetry' within Terraform provisioner job logs, which indicates the execution of unauthorized data-collection logic within a compromised or backdoored Terraform module.
Detects execution of Coder-related processes or scripts where sensitive configuration parameters, such as database credentials or authentication tokens, are passed via command-line arguments. This behavior can lead to the exposure of credentials to other users or processes on the system through process listing.

This rule detects the execution of specific DLP-related shell scripts (dlp.sh, dlp-docker.sh) being invoked by Terraform processes. This pattern may indicate suspicious automated infrastructure configuration or an attempt to bypass security controls by leveraging IaC tools to execute scripts.

This rule detects DNS requests to common cloud-based infrastructure providers often used by adversaries for Command and Control (C2) operations, including AWS API Gateway, Azure App Service, Google Cloud Functions, and Cloudflare Workers. These domains are frequently leveraged to host redirectors, beaconing infrastructure, or malicious payloads.
Detects a hardcoded PEM RSA public key embedded alongside JSCeal-specific compiled V8 bytecode obfuscation artifacts, used to encrypt exfiltrated data or C2 communications
Detects the creation of a WordPress administrator account within one hour of a recorded web request to a known web shell path (Mushr00w) or suspect plugin upload directory. This correlation is a high-fidelity indicator of post-exploitation persistence and administrative account hijacking.
Detects the creation, modification, or renaming of PHP files within the 'wp-content/uploads' directory of a WordPress installation. This pattern is commonly indicative of an attacker uploading a web shell to maintain persistence or execute arbitrary code on a compromised web server.
This rule detects when a .zip archive file is created on a host. The creation of archive files can be a precursor to data exfiltration or a method for adversaries to bundle malicious tools for movement.
Detects the execution of bash or shell commands associated with a hidden directory '.task' and a specific script 'tokenlinux.sh'. This pattern is indicative of potential persistence mechanisms, unauthorized script execution, or command-and-control (C2) activity in a Linux environment.

Detects periodic TLS network beacons to external destinations on port 443, characteristic of the BridgeAgent malware. The rule identifies suspicious outbound connections that exhibit consistent, repetitive behavior patterns, potentially indicating C2 communication. It is recommended to correlate this network activity with EDR alerts focusing on masquerading processes, specifically instances where binaries like gnome-shell are running as root and persisted via service mechanisms like zabbix_agent.service.
Detects network-based command signaling shared by the Fire Ant/REPTILE-derivative backdoor and its reverse-tunneling implant capability. Identifies the 'magic string' activation sequence and matching 'kill marker' termination sequence over TCP and UDP — indicative of packet-triggered backdoor activation, port-knocking style C2, or reverse-tunnel establishment via raw socket communication.
Detects the execution of base64 decoded commands piped directly into a Unix shell (sh, bash, or zsh). This is a common technique used by attackers to execute obfuscated payloads, often found in reverse shells or stage-two malware delivery, where the attacker encodes their command to bypass simple keyword-based security filters.
This rule detects the creation, modification, or renaming of a file named '/tmp/helper' within a one-day window of a 'curl' or 'wget' command-line execution that references this specific path. This pattern is commonly indicative of an adversary downloading and staging malicious tools or payloads in a temporary directory on Linux systems.
