This rule detects the use of PowerShell or common command-line network tools (curl, wget) to download or interact with files containing references to WPPConnect or WhatsApp automation JavaScript libraries. It flags activity where the parent process is a common LOLBIN (Living Off the Land Binary) or originates from suspicious locations such as user temporary directories, which is indicative of malicious automated tooling or script execution.
Detects potential abuse of MSBuild.exe or DotNet.exe as a proxy for executing arbitrary code. The rule identifies processes executing MSBuild or specific DotNet CLI operations (build, publish, test, pack) that do not originate from expected binary names, indicating a possible attempt to bypass application execution defenses using trusted developer utilities.
This rule detects potentially malicious JavaScript files associated with known malicious patterns or suspicious 'preinstall' script behavior within Node.js environments. It monitors for the execution of specific suspicious filenames or the use of common Node.js package management tools (npm, yarn, etc.) in contexts suggesting code generation or build-time abuse.
This rule detects the presence of specific file artifacts and directory paths associated with the 'Mini Shai-Hulud' malicious campaign, which involves the compromise of the 'openapi-react-query-codegen' npm package. It monitors for indicators of compromise (IOCs) such as specific malicious JavaScript and shell script filenames, as well as persistence artifacts like plist and service files.
Detects the presence of known malicious file hashes associated with the Mini Shai-Hulud supply chain compromise (e.g., malicious npm package artifacts). The rule monitors device file, process, and image load events for SHA256 matches.
Detects unusual executables that are not recognized web browsers initiating direct network connections to Google DNS-over-HTTPS (DoH) services. This behavior is often associated with malware attempting to bypass local DNS resolution to communicate with command-and-control servers covertly.
This rule detects potential malicious activity where a process attempts to communicate over DNS over HTTPS (DoH) using common public resolvers (e.g., Google DNS) while simultaneously establishing persistence via Windows Registry 'Run' keys. It excludes common, legitimate applications known to use DoH, focusing on unexpected processes. The detection relies on correlating network events (DoH to known public resolvers) with registry modification events occurring within a 30-minute window of the network activity.
Detects the execution of 'conhost.exe' with command-line arguments '--headless' and 'cmd' initiated by 'svchost.exe' as part of a scheduled task. The command executes from user-writable directories such as AppData, ProgramData, or Temp, which is a common pattern for fileless or staged payload execution initiated by malicious scheduled tasks.
This rule monitors network connections for traffic directed towards domains and IP addresses associated with a known malicious campaign distributing fake VPN browser extensions, as identified by Socket.dev. These domains and IPs are used for command and control or malicious communication by the browser extensions.
