Detects anomalous, high-frequency interaction with the Windows clipboard by explorer.exe. This activity is often associated with unauthorized data collection or exfiltration attempts by malware residing within or masquerading as the Windows shell.
Detects process execution patterns and DNS requests associated with the GHAPPIER malware staging infrastructure. The rule monitors for specific command-line arguments involving known malicious scripts, temporary files, and deployment infrastructure (e.g., Vercel) often used for delivering or executing malicious payloads via node.js environments.
Detects a process that deletes its own executable file immediately after launching. This anti-forensic behavior is commonly utilized by remote access trojans (RATs) and other malware to minimize their footprint and evade file-based forensic analysis.
This rule detects the GHAPPIER multi-stage loader, typically observed in 'indexe.cjs' files. The loader fetches and executes a remote payload from a Vercel-hosted domain (primevector-app924560.vercel.app) using 'eval' on retrieved content, or matches specific payload identification tags.
Detects network activity associated with NetSupport Manager remote access software, specifically targeting DNS lookups, TLS SNI connections, and direct TCP beaconing to a known-malicious infrastructure IP. This rule is designed to identify unauthorized use of legitimate remote support tools for command and control purposes.
Detects evidence of the PIVOTPIPE .NET loader attempting to disable AMSI scanning. The detection focuses on activity related to patching the 'AmsiScanBuffer' function within 'amsi.dll', specifically identifying the use of the hex signature '80070057' or direct references to the function name, which is an indicator of an AMSI bypass attempt performed to facilitate malicious code execution.
Detects the execution of rundll32.exe with a command line containing 'DavWWWRoot', indicating the loading of a DLL payload directly from a remote WebDAV share. This behavior is commonly associated with ClickFix/ClearFake infection chains where users are tricked into executing malicious payloads hosted on attacker-controlled WebDAV servers.
Detects execution of code using indirect syscalls or ntdll unhooking techniques, often associated with the PIVOTPIPE loader/RAT. The rule monitors for EDR indicators of evasion such as syscall stub execution, direct/indirect Nt* system call invocation, or call stacks originating outside of ntdll.dll, intended to bypass userland security hooks.
Detects network activity associated with the GHAPPIER implant beaconing to a hardcoded command and control (C2) server. The rule monitors for established TCP connections on port 15152 that contain specific JSON status indicators and the string 'ghappier' in the payload, which are characteristic of this malware's communication protocol.
This rule monitors for the presence of a specific, known malicious package (@dforge-core/dforge-mcp version 0.2.21) being referenced in file paths, indicative of a software supply chain compromise or the distribution of malicious dependency artifacts.
