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.
Detects the creation of cook.pth or cook.py in Python site-packages or dist-packages directories by package managers or interpreters, followed by a Python interpreter execution on the same device within one hour. This pattern matches the malicious supply chain behavior observed in compromised LiteLLM versions (e.g., 1.107.0) utilizing .pth auto-import chains for persistence and execution.
Detects attempts to disable or tamper with Windows Defender settings, services, or registry keys via command-line execution (such as reg.exe, PowerShell, or sc.exe) or direct registry modifications.
Detects post-exploitation behavior where a PaperCut server Java process spawns local account creation or administrator reset followed closely by Active Directory enumeration on the same host, indicating potential post-RCE meterpreter activity.
Detects PowerShell execution spawning 7zr.exe to extract password-protected 7z archives using overwrite and password switches within a specified timeframe, or referencing specific malicious IOC file names and domains.
Detects a sequence where PowerShell downloads an .msi installer file from Azure Blob Storage, followed closely by msiexec.exe spawning a PowerShell process on the same device.
Detects mshta.exe launched with an inline javascript: one-liner that chains MSXML2.XMLHTTP to download, ADODB.Stream to write to disk, and WScript.Shell to execute. This identifies the ClickFix social engineering variant that fetches and executes payloads without using PowerShell.
Detects anomalous activities associated with potential PHP2Shell exploitation or webshell deployment where a web server worker (such as Apache, HTTPD, or PHP) spawns a Unix shell containing suspicious utility tokens, drops a PHP file outside excluded directories, or creates a PHP session-derived file.
Detects the installation or service setup of unauthorized remote access tools (such as AnyDesk, TeamViewer, or ScreenConnect) followed by outbound public network connections from the same device within a one-hour window.
Detects the correlation of two or more distinct discovery tools or artifacts (such as SharpShares, NetScan, NetExec, ShareFinder, and specific nltest.exe domain trust commands) executed on the same device within a one-hour window.
Detects observable consequences of remote code execution on a GitLab server (CVE-2026-97229), specifically where GitLab application services (such as Puma, Sidekiq, Ruby, GitLab Rails, or GitLab Workhorse) spawn a shell or interpreter with suspicious command-line parameters or external network utilities.
Detects PowerShell registering a logon scheduled task that executes a Trays.exe binary from an AppData Yandex Trays path with the -tray argument, or a scheduled task specifically named 'Microsoft apdate'. Associated with the RareWolf AnyDesk dropper batch script.
Detects suspicious Ghostscript execution patterns where Python spawns Ghostscript with dangerous I/O pipe arguments or disabled SAFER mode, or where Ghostscript spawns shell interpreters.
Detects the presence of Tailscale binaries (tailscale.exe, tailscaled.exe) on a device within 24 hours of other campaign-specific toolkit components such as kitanai.exe, nandemo.exe, ufw.exe, or upd-ms.bat, indicating potential unauthorized remote access setup.
Detects indicators of compromise including Bash-based reverse shells communicating with a C2 domain on port 7070, outbound network connections from web server and shell processes to the same C2 infrastructure, and the dropping of known suspicious plugin archive files (akismetv4-plugin.zip, Hlx.zip, template.zip).
