Detects a sequence where a process is launched from or references the hidden /tmp/.x directory (indicative of cryptominer deployment), followed within 30 minutes on the same device by a process-check command (such as ps, top, or htop) referencing XMRig or /tmp/.x.
Detects Microsoft Word (winword.exe) spawning the Windows command shell (cmd.exe) to execute batch scripts (.bat or .cmd files). This behavior is commonly associated with malicious document macros attempting to drop and execute secondary payloads, excluding common system paths to reduce false positives.
Detects the sequence where a private key file is written to the host followed by the execution of ssh.exe with parameters indicating a reverse port forwarding tunnel (-R), an identity file (-i), and background execution (-N or -f) within a 30-minute window.
Detects PowerShell processes combining local loopback listener terms (such as HttpListener or TcpListener) and authentication or web request cmdlets referencing 127.0.0.1 or localhost, correlated with local network loopback connections.
Detects node or agent-initiated npm installation commands (such as npm install or npm i) executed within 24 hours of creating or modifying a developer assistant instruction file (such as AGENTS.md, CLAUDE.md, .cursorrules) in common user directories like Downloads, Desktop, or Temp.
Detects instances where web server processes or PHP interpreters (apache2, httpd, php-fpm, php) spawn a shell process (sh, bash, dash). This behavior is often indicative of post-exploitation activity such as remote code execution (RCE) via PHP session upload progress or web shell activity.
Detects the execution of the Chisel tunneling tool configured as a client building a reverse SOCKS tunnel with flags such as TLS verification disabled, keepalive, or authentication, or communicating with a known C2 endpoint.
Detects the execution of tooling routed through a reverse SOCKS5 pivot via wrappers such as via_socks.sh, proxychains4 with a SOCKS5 configuration, or LD_PRELOAD injection of libproxychains.so.
Detects instances where the Claude Code AI assistant CLI or related node processes spawn command-line shells (such as cmd, powershell, bash, sh, zsh), followed by system firewall rule modifications on the same device within a 4-hour window.
Detects PaperCut server processes (such as pc-app.exe, pc-server.exe, or Java running PaperCut) spawning command shells or utility binaries associated with credential dumping, internal reconnaissance, or pivoting.
Detects a sequence where PowerShell downloads an .msi file from Azure Blob storage (blob.core.windows.net), followed by msiexec.exe spawning PowerShell on the same device within 30 minutes.
Detects suspicious post-exploitation activities, reconnaissance, and command execution originating from web server and PHP lineage processes, indicating potential webshell activity or compromised web applications.
Detects a PaperCut server Java process spawning a local account creation or local administrators group addition, followed closely by Active Directory domain or computer enumeration from the same host within a 30-minute window.
Detects WinRAR or 7-Zip extracting an archive with a hard-coded password supplied via command line from a cmd.exe batch parent, using switch patterns associated with the RareWolf AnyDesk dropper.
Detects when a Java or JavaW process spawns a Unix shell (bash, sh, dash) with command-line arguments indicative of a reverse shell utilizing /dev/tcp and interactive shell flags.
Detects web server processes (such as apache2, httpd, nginx, php-fpm) spawning a shell or curl process that performs LDAP queries using curl against URLs. This activity is indicative of Remote Code Execution (RCE) vulnerabilities being exploited against web applications to perform internal reconnaissance or LDAP enumeration.
Detects Microsoft Edge (msedge.exe) spawned by command shells or script hosts with hidden or headless window parameters, or communicating with webhook.site, which is commonly indicative of malicious browser automation or exfiltration.
Detects instances where the Apache web server spawns a shell process (sh, dash, bash) which subsequently executes common discovery or callback utilities (such as id, curl, wget, php, hostname, or uname), typically indicative of web application exploitation or remote code execution.
Detects instances where a browser process (Chrome, Edge, Firefox, Brave) is observed on a device shortly before an explorer.exe-initiated PowerShell, PWSH, or CMD process executes a command containing download strings or script execution patterns (such as DownloadString, Invoke-WebRequest, IEX, or encoded commands) referencing URLs.
Detects node.exe or npm spawning command shells or Living-off-the-Land Binaries (LOLBins) as part of npm preinstall or postinstall lifecycle scripts.
Detects the deployment of the ARTEX AI penetration testing framework via Docker/Docker-compose combined with the execution of offensive security and scanning tools (such as nmap, sqlmap, nuclei, httpx, apktool, frida) on the same host within a specified timeframe.
