001
This rule detects a suspicious sequence of events where a process with a name resembling an updater (AutoUpdate.exe or au.exe) accesses a specific remote configuration file from a herokuapp.com URL, followed by the creation or modification of specific application binaries (e.g., InstaTime.exe, ffmpegsumo.dll). This pattern is indicative of a supply chain compromise or an automated software update hijacking where malicious binaries are staged to replace legitimate application components.

This rule detects the execution of processes or network connections that impersonate 'WhatsApp' or 'Instagram' companion applications. It identifies specific file names and process command lines that mimic these applications, often associated with browser-launched or malicious payloads, and monitors for associated network traffic directed toward suspicious endpoints like herokuapp domains.

Detects the creation of PHP files within the 'wp-content/uploads/elementor/forms/' directory of a WordPress installation. This behavior is highly suspicious as it often indicates an attempt by an attacker to deploy a web shell or other malicious script following successful exploitation of the Elementor plugin, which allows for arbitrary file uploads.

Detects the execution of known potentially malicious tools cplsupport.exe and wtass.exe with install parameters, or the creation of a Windows service associated with these filenames using sc.exe. This activity is indicative of service-based persistence or malicious software installation.

This rule detects potential persistence mechanisms in a PostgreSQL database by identifying the creation of a new shared library file (e.g., .so or .dll) within PostgreSQL plugin directories, followed by a modification to the PostgreSQL configuration files (postgresql.conf or postgresql.auto.conf) within a short 30-minute window. This behavior is indicative of an attacker registering a malicious shared library to be loaded upon database startup, a technique associated with PostGREShell-style post-exploitation.

This rule detects potential command and control (C2) activity associated with the CurlRAT malware. It monitors for both the execution of 'curl' or 'curl.exe' processes with command lines containing known C2 domains, and network traffic originating from internal devices directed toward those same domains.

Detects suspicious execution of PowerShell or Mshta spawned from Explorer.exe. It looks for specific malicious indicators including references to known malicious domains, PowerShell encoding flags, hidden window arguments, or Mshta HTTP requests, which are common patterns for fileless malware or dropper execution.

Detects processes that access sensitive browser credential or cookie files (e.g., Login Data, Cookies) followed by network activity within a 10-minute window, which is a common behavior pattern of information-stealing malware such as Amatera or ACR Stealer.

Detects outbound web requests directed at public NPM mirrors and CDNs (unpkg, npmmirror, yarnpkg, jsdelivr) that contain strings matching known malicious package names associated with the 'Beamglea/ClickFix' campaign. This activity is typically indicative of a victim visiting a deceptive Cloudflare CAPTCHA phishing page designed to execute malicious scripts in the browser.

This rule detects file access, creation, modification, or renaming operations involving sensitive files associated with cryptocurrency wallets (Bitcoin, Electrum, ElectrumSV), game account configurations (Battle.net, Steam, Minecraft), and browser-based cookies (Roblox). The rule filters out legitimate process interactions, identifying suspicious activity from unknown or unauthorized applications potentially attempting to exfiltrate credentials or session tokens.

This rule detects instances where LockAppHost.exe or a variation of it (likely used as a proxy) initiates processes or command-line arguments that interact with Windows services, scheduled tasks, or Windows Defender configurations. This behavior is indicative of an adversary attempting to disable security features, suppress Windows updates, or manipulate system services to evade detection.

Detects suspicious executions of 'nslookup.exe' and 'svchost.exe' when triggered by the Windows LockAppHost process. This pattern is indicative of potential process injection or masquerading attempts by malicious actors using legitimate system processes as proxies for unauthorized activity.

This rule detects potential cryptocurrency mining activity where known miner executables (specifically XMRig) or malicious scripts/processes are masquerading as or being spawned by 'LockAppHost.exe' or 'LockAppHost14a02b.exe'. It also monitors for subsequent attempts by these processes to terminate security-related tasks or establish persistence via registry run keys.

This rule detects the presence of 'winpty-agent.exe' or 'winpty.dll' in proximity to 'node.zip' or 'build.zip' files within common user-writable or temporary directories ('AppData\Local\Temp', 'AppData\Roaming', 'ProgramData', 'Users\Public'). This pattern is often associated with the staging and execution of malicious tools or command-line wrappers in non-standard locations, bypassing legitimate application installation directories.

Detects Terraform processes (init or apply) executed in conjunction with suspicious post-deployment indicators, such as references to '.terraform' folders, execution of automation scripts like 'dlp.sh' or 'dlp-docker.sh', or access to sensitive telemetry data external to typical infrastructure management.
