Detects the GHAPPIER loader pattern: a top-level require('https').get() call to the primevector-app924560.vercel.app C2 that evals the response, disguised inside a large benign-looking JavaScript benchmark file
Detects the GHAPPIER loader payload concealed as a single line deep inside a large (~99KB) legitimate-looking JavaScript file, fetching and eval'ing remote code

Detects the GHAPPIER loader identified across 65 public npm/GitHub repositories and 22 developer accounts, based on its embedded remote-fetch/eval pattern and campaign markers

This rule monitors for network connections to known malicious domains and IP addresses, as well as the presence or execution of files with specific SHA256 hashes known to be associated with threat activity. The indicators focus on Vercel-hosted domains and specific file hashes linked to recent campaign activity.
This rule detects potentially malicious child processes spawned by Visual Studio Code (Code.exe) when using VS Code tasks (tasks.json). It identifies suspicious CLI arguments often associated with downloading, executing, or obfuscating scripts (e.g., PowerShell, curl, python, mshta) that are not part of standard development workflows like npm, yarn, or git, which are explicitly filtered out as noise.

This rule monitors for indicators of compromise (IOCs) associated with a specific AutoIT-based malware delivery chain. It tracks the execution and presence of specific malicious file names and SHA256 hashes, as well as network connections to a identified command-and-control (C2) infrastructure IP address (158.51.122.136). The detection spans file creation, process execution, image loading, and network communication events to identify the multi-stage attack lifecycle.
This rule detects suspicious usage of certutil.exe for file downloading or the execution of the Chisel proxy tool, specifically targeting connections or authentication towards the suspicious IP address 69.48.228.86. This behavior is indicative of C2 communication or ingress tool transfer.
Detects HTTP downloads from GitHub involving specific repositories and archive naming patterns commonly associated with the 'NightEagle GhostContainer' threat activity. These patterns involve downloading ZIP files disguised as development or resource packages (e.g., 'mirror-js', 'browserthemes', 'resource-pack').
Detects potential ClickFix-style social engineering attacks where a victim is prompted to execute an encoded PowerShell command (often via copy-paste into a terminal). The rule specifically monitors PowerShell processes initiated by shell environments (explorer.exe, cmd.exe, or WindowsTerminal.exe) that execute encoded, hidden scripts to perform multiple suspicious network requests for files (e.g., .zip, .enc, .bin) from non-standard domains.
This rule detects activity associated with the exploitation of PaperCut vulnerabilities. It looks for connections to known malicious IP addresses, the presence of specific credential harvesting tools, reconnaissance commands (whoami, tasklist) executed by the PaperCut application (pc-app.exe), suspicious PowerShell downloads of AnyDesk, and unauthorized access to PaperCut configuration files or log files containing known exploit strings.
Detects HTTP GET requests to a specific URL path containing an image file, which is associated with the delivery of the LausivLoader malware. The rule monitors for external connections to the domain 'yapw.life' requesting a PNG file, a technique often used for steganographic payload delivery.
This rule detects PowerShell processes attempting to download specific ZIP files (e.g., DriverInstaller.zip, Automata-20.zip, ww.zip) from Backblaze B2 cloud storage buckets. This pattern is commonly associated with the delivery of malicious payloads or staged tools.
This rule detects potentially malicious activity by monitoring for file creation events within a specific 'FitnessPrograms' directory path and the execution of suspicious processes containing keywords related to command-and-control-like behavior (e.g., 'download_and_execute', 'checkCoachInstructions').
This rule detects the execution of PowerShell or Command Prompt processes that attempt to bypass execution policies while performing file downloads from suspicious domains (mnl.ac) or IP addresses (149.255.35.135). It also flags the use of common web-request cmdlets (Invoke-WebRequest, IWR, DownloadString, DownloadFile) to fetch scripts named 'configuration.ps1'. The rule includes detection for obfuscated commands using caret (^) symbols often used to evade keyword-based security filters.
