Detects the WAV-based loader staging technique: a RIFF/WAVE file carrying a high-entropy appended blob, or a companion DLL chain (rdCore.dll/WMPCL.dll/WPFLocalizeExtension.dll) referencing the hidden audio payload and the encrypted monitor.raw container used to unpack the final RAT
This rule detects potential DLL sideloading activity where legitimate, signed binaries (such as COTFileReadApp.exe or DeElevate64.exe) are executed from non-standard directories (e.g., AppData, Temp, Downloads) while loading specifically identified malicious or sideloaded DLLs. The detection identifies patterns where these binaries operate outside their expected vendor installation paths, indicating a likely attempt to hijack execution flow.

Detects outbound network connections to a known malicious IP address (45.94.31.112) associated with C2 beaconing. The rule identifies communication directed to specific API endpoints (/api/v3/r, /api/v3/s) originating from processes other than common web browsers, suggesting the use of dedicated beaconing or malware agents (e.g., direct WinHTTP usage).
Detects instances where processes typically associated with browser-related tasks (smartscreen.exe, ctfmon.exe) load ntdll.dll while another process on the same device is running with browser-specific command-line arguments (e.g., --user-data-dir, --profile-directory). This pattern is often indicative of process injection or credential harvesting attempts where an adversary attempts to interact with or scrape data from active browser sessions.
This rule detects scenarios where an AI agent executes shell commands or system-level tools immediately after receiving a prompt injection attack from an untrusted source. It correlates agent audit logs—specifically identifying tool calls flagged for prompt injection—with actual endpoint process creation events. It flags process execution as 'High' severity if the command line matches common malicious patterns like encoded commands, IEX, or attempts to access credential material (e.g., lsass, mimikatz).

Detects reconnaissance behavior (System Information, Account, and Network Discovery) performed by processes associated with AI and LLM coding assistants. The rule monitors for a chain of suspicious activities, such as executing discovery commands or excessive network scanning within a 10-minute window, identifying potential misuse of developer-oriented agent tools for post-exploitation reconnaissance.

Detects the creation of a new local account that is immediately followed by (or associated with) execution from a process identified as an AI development or agent-based tool (e.g., Cursor, GitHub Copilot, Ollama). The rule correlates process creation events with Windows Security Event ID 4720 (User account created) and optionally checks for subsequent addition to the local Administrators group. This logic aims to surface potential unauthorized credential creation triggered by automated AI coding assistants or LLM-driven workflows.

Detects a file named dnsapi.dll created/modified outside System32/SysWOW64/WinSxS (the only legitimate locations for the real system DLL). Now requires the file to BOTH land in one of the known NeedyMantis sideload staging folders AND match the published 3448-byte spoofed-config size -- previously the size check alone could match unrelated dnsapi.dll copies anywhere on disk; requiring both signals together removes that bypass.

Detects service-creation commands (sc create / New-Service / reg add under a Services key) whose COMMAND LINE itself references a known NeedyMantis binary name or sideload staging folder. Requiring the malicious reference to appear in the command being executed -- rather than merely in the calling process's own folder location -- removes false matches from unrelated legitimate software that happens to be installed under a similarly-named folder.
Detects >=2 of the four NeedyMantis archive-extraction artifacts (encryptbase64.ps1, dnsapi.dll, ws2_32.dll, msvcrt140.dll) written by the same process within 60 seconds. Anchored to the known sideload staging directories (ProgramData/ProgramFiles subfolders used by the Poedit/curl/Vim/TightVNC/Office/Broadcom/Intel/NVIDIA-masquerading bundles) and excludes System32/SysWOW64, since ws2_32.dll and dnsapi.dll are legitimate system DLL names that would otherwise cause noise if matched by name alone anywhere on disk.

Detects Impacket-style hands-on-keyboard staging: a NeedyMantis bundle file dropped by cmd.exe/wmiprvse.exe/services.exe carrying the distinctive remote-execution fingerprint (ADMIN$ share reference, %COMSPEC% invocation, or 2>&1 output redirection used by wmiexec/smbexec/atexec), followed within 15 minutes by execution referencing the same bundle folder with the same fingerprint. Requiring the ADMIN$/%COMSPEC%/redirection fingerprint on both the copy and the execution -- rather than just matching on common process names like cmd.exe or svchost.exe -- removes the bulk of ordinary software installation and update activity that also uses cmd.exe to stage files.
