Detects execution of TuxBot v3 multi-architecture ELF binaries, characterized by architecture-specific suffixes (e.g., tuxbot.x86_64) or the presence of the 'Infected By Akiru' banner in command-line arguments. These indicators serve as proxies for identifying this specific LLM-generated bot agent on disk or during runtime execution.
Detects anomalous web server scanning activity where a single source IP performs rapid requests against multiple common administrative or login panel paths (/admin, /wp-admin, etc.) while utilizing randomized ephemeral source ports. This behavior is consistent with automated enumeration scanning, such as that performed by the TuxBot v3 malware.
Detects the execution of Mimikatz or the use of specific command-line arguments (e.g., sekurlsa::logonpasswords) known for extracting sensitive credentials from the Local Security Authority Subsystem Service (LSASS) process memory. The rule monitors both process creation command lines and raw process memory read operations targeted at lsass.exe.
Detects outbound POST requests using the grpc-web+proto content type where the X-Request-Id header contains a base64-encoded JSON blob. This pattern is associated with exfiltrating sensitive data, such as mnemonic phrases or private keys, to a malicious endpoint masquerading as an Injective testnet gRPC-web node.
Detects the registration of a new FIDO2 security key or passkey in Entra ID that is associated with a sign-in from an unmanaged or non-compliant device shortly before or after the registration. This behavior often suggests a vishing or social engineering scenario where an attacker guides a user through an authentication method registration process while impersonating IT support.
Detects the execution of MokManager UEFI binaries or administrative activity via the mokutil utility targeting the MokListX denylist. This activity is indicative of Secure Boot configuration changes, such as enrolling unauthorized certificates or bypassing MOK (Machine Owner Key) denylist enforcement, which can facilitate the persistence or execution of malicious boot-level code.
Detects malicious downloader activity where mshta.exe or a spawned runexe.bat script utilizes PowerShell's Net.WebClient to download and execute secondary payloads. This is a common pattern for stage-two malware delivery.
This rule detects tampering with Microsoft Defender by monitoring registry modifications to Image File Execution Options (IFEO) used to attach debuggers to security processes. It also detects the dropping of the 'kvckiller.sys' kernel driver into System32\drivers, which is associated with disabling security software at the kernel level, and the execution of processes containing 'wsftprm' in the command line.
Detects the installation or referencing of the malicious @injectivelabs/sdk-ts package version 1.20.21. This specific version was identified as containing a credential-stealing backdoor disguised within telemetry code.
Detects process injection where itcsrvup64.exe (the ViPNet Update System component, sideloaded per HelloNet campaign) creates a remote thread in svchost.exe using NtWriteVirtualMemory/NtCreateThreadEx, targeting the netsvcs service host process.
