Detects browser cache smuggling (ClickFix/FileFix delivery mechanisms) where a non-browser script interpreter or LOLBin accesses a browser HTTP-cache directory and writes an executable or script payload outside the cache, followed shortly by the execution of a payload from a user staging directory.
Detects web server processes (apache2, httpd) spawning a Unix shell (sh, dash, bash) which subsequently executes curl, wget, or php to perform an external HTTP fetch or download. This behavior is commonly associated with PHP or web application post-exploitation callbacks (webshells).
Detects when AI coding agent processes (such as Claude, Cursor, Copilot, Windsurf, Codeium, or Aider) spawn command shells or download utilities with command lines indicative of downloading and executing external payloads.
Detects command execution patterns on NetScaler appliances involving the extraction of system details (id, uname, hostname, nsrelease) and writing or echoing them into HTML files within NetScaler web directories, indicative of web shell installation or staging.
Detects cmd.exe launched from the Windows Run dialog (explorer.exe
parent) downloading a payload with a living-off-the-land transfer utility such as
certutil, bitsadmin or curl. ClickFix pasted commands frequently chain cmd.exe with
these built-in binaries to fetch the secondary malware stage.

Detects a VS Code-family editor or extension host process running 'git config --global user.email' and, within one minute from the same parent process, a curl public-IP lookup (ifconfig.me / api.ipify.org), the host-profiling step of the trojanized anthropic.claude-code loader.
Sweeps endpoint telemetry for known IOCs from the trojanized anthropic.claude-code (Open-VSX v2.1.313) SSH backdoor: C2 IP 134.209.82.225, beacon URL, extension.js and tunnel key SHA-256 hashes, and ifconfig.me lookups from VS Code-family/extension-host processes. Results are summarized per device and IOC.
Detects the setting of the TS_SERVE_ALLOW_ALL_INTERFACES environment variable or registry key combined with the execution of Tailscale serve or funnel commands on the same device within a 24-hour window, potentially indicating unauthorized exposure of local services.
Detects the archiving of the ProgramData AnyDesk directory using WinRAR/RAR with header encryption or the PowerShell Compress-Archive function, which indicates configuration staging for potential exfiltration.
Detects potential C2Agent parent-spoofing behavior characterized by short-lived scheduled tasks (created and deleted within a 10-minute window with names matching c2a_<n>) or process relaunches carrying specific -fork2 command-line markers.
Detects PowerShell using System.Net.WebClient DownloadFile or related commands to fetch tool dependencies (such as 7z, MSTSCLib, ffmpeg) from GitHub repositories associated with the 'websalat' naming convention, indicative of Salat Stealer or similar tool-loading activity.
Detects GitLab backend processes (such as puma, sidekiq, rails, ruby, bundle) spawning shells, scripting interpreters, or network tools with suspicious command-line parameters, potentially indicating post-exploitation activity or vulnerability exploitation.
Detects behavioral indicators of shell-driven cryptocurrency miner staging where a hidden .trace file or binary is created, executed, or referenced via command-line arguments within go2rtc or shared memory directories (/config/, /opt/go2rtc/, /etc/go2rtc/, /.config/go2rtc/, /dev/shm/), alongside indicators of mining pools or software such as XMRig.
Detects the execution of the public Horizon3.ai PoC exploit for CVE-2026-106173 (FortiSIEM gRPC path traversal RCE) utilizing python interpreters with specific command-line arguments indicative of the exploit tool.
Detects the creation of AI coding assistant configuration files (such as .cursorrules, CLAUDE.md) in user directories (Downloads, Desktop, Temp) by non-git processes, followed within a short time window by execution of interpreters or tools (like node, npm, powershell, cmd, curl) with suspicious command line parameters indicating possible download or script execution.
Detects potential remote code execution against Xinference or Xoscar pool processes, identified by an inbound network connection accepted by a Python-based worker followed shortly by the spawning of a shell process (sh, bash, dash) by the same process.
Detects an Xoscar or Xinference Python actor pool process spawning a Unix shell child process with suspicious command-line flags (such as reverse shell indicators, downloads, or base64 decoding), potentially indicative of cloudpickle deserialization remote code execution (CVE-2026-49950).
Detects web server processes (Apache httpd, apache2, php-cgi, php-fpm) spawning a Unix shell (sh, bash, dash) that executes a wget or curl command piped directly into the shell for execution, indicative of potential remote code execution or web shell activity.
Detects observable hiding actions targeting ScreenConnect (ConnectWise Control) clients, such as modifying registry keys to hide uninstall entries, using attrib.exe to set hidden attributes, or launching management tools with hidden window styles.
Detects the execution of administrative commands and scripting interpreters spawned by the VMware Tools daemon (vmtoolsd), which may indicate an adversary leveraging ESXi guest operations for remote code execution.
Detects instances where a web browser accesses a domain listed in the 'AdFection_Domains' watchlist, followed closely by the browser spawning a script interpreter (such as PowerShell, wscript, cscript, mshta) or dropping an executable/script file in user profile or temporary directories.
