This rule detects outbound network connections to a specific typosquatted domain 'perplexity-ai.online'. This domain is associated with a malicious browser extension designed to intercept and exfiltrate search queries before forwarding them to legitimate search providers.
Detects the creation or modification of an mcp.json file within IDE configuration directories (.vscode, .amazonq), followed shortly by the execution of shell or interpreter processes (bash, sh, cmd, powershell, npx) by the IDE process. This behavior suggests the installation of a malicious Model Context Protocol (MCP) server configuration that could facilitate command execution or persistence within the developer environment.
Detects suspicious child process activity originating from common IDEs or AI language server processes that indicates AWS credential exfiltration. The rule monitors for command-line patterns indicative of credential dumping or exfiltration, such as the use of AWS CLI commands, curl, or npx with the Model Context Protocol (MCP) in conjunction with attempts to access sensitive environment variables or redirect output.
This rule detects potentially malicious child processes spawned by Amazon Q or VS Code language server processes. It monitors for suspicious shell command-line invocations (e.g., bash, sh, cmd.exe) or tools (npx, python) immediately following the activation of language server processes, specifically looking for patterns associated with the unauthorized auto-loading or execution of Model Context Protocol (MCP) configuration files or utilities, potentially related to vulnerability patterns involving workspace-based execution.
Detects the Ghidra reverse engineering suite spawning suspicious child processes such as command shells, scripting interpreters, or network utilities. This activity often indicates an attempt to automate reverse engineering tasks or interact with the system in an unintended manner by potentially malicious scripts or plugins.
Detects web server processes (e.g., PHP, IIS, Apache, Nginx) spawning suspicious child processes including shells (cmd.exe, powershell, bash) or network utilities (curl, wget, netcat), which is often indicative of webshell exploitation or post-compromise activity.
Detects a suspicious sequence of events where a Gitea act_runner process spawns a container with dangerous namespace or capability flags (e.g., --pid=host, --cap-add=ALL) followed by the execution of 'nsenter' in the same environment, indicating an attempt to escape the container to the host.
Detects the creation or modification of a file named 'help.php' within directories associated with REDCap deployments. This activity is a known persistence mechanism used by threat actors like UNC6508 to establish web shell access.
Detects Gitea act_runner spawning Docker containers with dangerous runtime flags (e.g., --pid=host, --privileged, --cap-add=ALL) that facilitate host namespace escape. This activity is indicative of exploitation of CVE-2026-20896, where malicious CI/CD workflow YAML files inject these options to break out of the container sandbox and access the host filesystem.
Detects unauthorized attempts to escalate privileges within the MyBB Admin Control Panel (ACP) by creating a new user account with administrator privileges (group 4). This rule identifies when an account with limited management permissions exploits the ACP to assign a new user to the administrator group, effectively bypassing intended permission restrictions.
Detects the use of the 'cp' command within a Docker container context to access files outside the current working directory, identified by the usage of parent directory traversal (..). This pattern is often associated with container escape attempts or unauthorized file access within a containerized environment.
This rule detects processes attempting to access sensitive Linux system files (/proc/[pid]/environ or /proc/[pid]/cmdline) or the specific file 'linux-process-env.json'. Such actions are indicative of an adversary attempting to perform system discovery, dump process environment variables for secrets, or collect process metadata.
Detects potential exploitation attempts involving ImageMagick and Ghostscript. It monitors for two primary suspicious behaviors: ImageMagick spawning Ghostscript from non-standard or hijackable file paths, and Ghostscript spawning shells or common script interpreters, which is a common indicator of command injection via image processing delegates.
Detects potentially malicious activity associated with the Ghidra reverse engineering framework, including the spawning of unexpected non-Java child processes, loading of suspicious project files (.gzf/.gar), loading of unsigned extensions from non-standard directories, and unexpected outbound network connections from decompiler or Java processes.
Detects unauthorized processes (Python, Node.js) accessing sensitive files such as browser login data, cookie stores, wallet files, and SSH/AWS keys, which are common indicators of credential theft and data exfiltration.
Detects rapid post-exploitation activity where a developer's workstation, upon executing VS Code (Code.exe), initiates outbound network connections to major cloud service or CI/CD provider APIs (GitHub, AWS, Azure, GCP) within 60 minutes. This behavior is indicative of the Lazarus Group 'Contagious Interview' campaign, where stolen credentials from developer environments are used to pivot into cloud infrastructure or CI/CD pipelines.
This rule monitors process creation events for 'git' or 'npm' command-line activities that are highly indicative of potential software supply chain attacks. It triggers when known malicious package names or suspicious patterns are detected within command-line arguments, or when a workflow involves a git clone followed by subsequent npm installation, which is a common vector for deploying malicious dependencies.
Detects instances where Python or Node.js processes access common cloud provider credential files (e.g., AWS, GCP, Azure). This behavior is often associated with infostealer campaigns, such as the 'Contagious Interview' campaign, where adversaries attempt to harvest stored cloud credentials for further compromise.
Detects instances where scripting or development processes (e.g., node.exe, python.exe, code.exe) access sensitive SSH private key files or PEM files, followed by an immediate outbound network connection to a non-private IP address within 60 seconds. This activity is indicative of credential exfiltration or unauthorized use of stolen keys.
Detects the execution of a bash script dropper ('isp.sh') associated with Langflow RCE exploitation (CVE-2026-33017). The rule triggers when command-line arguments indicate an attempt to download and execute the 'lambsys.elf' Go-based cryptominer from a known malicious IP address (83.142.209.214).
Detects post-exploitation system discovery and reconnaissance commands performed by PeopleSoft service accounts (psoft, oracle, linuxadm) on Linux hosts. This activity aligns with observed techniques from the ShinyHunters CVE-2026-35273 campaign, where compromised service accounts were used to map the local environment.
