Detects mshta.exe executing a remote HTA payload over HTTP/HTTPS, the initial fileless execution stage of ACR Stealer's Campaign 2. The retrieved HTA contains VBScript loaders that ultimately deploy obfuscated PowerShell and steganography-assisted in-memory shellcode.
Detects a renamed PSF-signed pythonw.exe (with an original file name of pythonw.exe but a different on-disk name) launched from a user-writable path under Users. The command line consists only of its own path, which is consistent with ._pth based path configuration abuse for loading attacker code stealthily.
Detects when the IIS worker process (w3wp.exe) spawns command-line utilities or script interpreters such as cmd.exe, powershell.exe, mshta.exe, wscript.exe, or cscript.exe. This behavior often indicates web application exploitation or webshell activity.
Detects the execution of rundll32.exe loading a DLL directly from common browser cache directories (Firefox, Chrome, or Edge), which is indicative of the SensePost cache-smuggling proof-of-concept technique.
Detects Java processes spawning PowerShell or Command Prompt to modify Windows Defender settings by adding exclusions for sensitive paths or extensions (such as AppData, Temp, Users Public, or ProgramData).
Detects potential debugger detection evasion attempts via command line arguments associated with debugging checks or process execution of debugging utilities, as well as persistence configuration using Image File Execution Options (IFEO) or AeDebug registry keys targeting debuggers.
Detects the usage of binaries such as 'net', 'sc' or 'powershell' in order to stop, pause, disable or delete critical or important Windows services such as AV, Backup, etc. As seen being used in some ransomware scripts
Detects the execution of potential tunneling tools from temporary directories (/tmp, /dev/shm, /var/tmp) using characteristic CLI arguments such as --listen, --token, --obfs, and --ws-path, or the known binary name 'ingredi_ws'.

Detects potential Linux privilege escalation and persistence activities by monitoring for the creation of persistence scripts in post_boot.d, modifications to the sudoers.template file appending NOPASSWD, or system configuration rebuilds shortly after sudoers template changes.
Detects a sequence of events on a single device where a shell (/bin/sh, /bin/bash, etc.) is copied to a path involving /usr/bin/dbus-authd using cp or busybox, followed by changing ownership to root, and subsequently setting the SUID permission bit within a 10-minute window.

Detects the execution of reverse engineering and decompilation tools such as JADX or Blutter against Android APK files or Flutter application binaries (libapp.so), as well as the creation of their typical output artifacts and staging folders.

Detects endpoint execution of specific known brute-force scripts and tools (such as ssh_brute.py, brute3.py, auto_login.py, etc.) using Python or shell interpreters, correlated with a high outbound network connection fan-out (50 or more distinct target IPs) from the same process.

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 creation of a scheduled task named "Windows Defender Advanced
Threat Protection Service" configured to run at system startup with SYSTEM privileges
and launch an executable named defender.exe. HoneyMyte (Mustang Panda) used this exact
schtasks command to establish boot persistence for the CoolClient backdoor sideloader,
masquerading the task and binary as a legitimate Windows Defender component.

Detects when the IIS worker process (w3wp.exe) spawns common system and network discovery utilities such as whoami, ipconfig, systeminfo, net, and others, which may indicate web shell activity or post-exploitation discovery.
Detects the execution of ntdsutil.exe with arguments to create an Install from Media (IFM) database backup, preceded shortly by a Remote Interactive logon (RDP) from a remote IP source, which can indicate adversary activity attempting to dump Active Directory credentials.
