Detects Azure AD sign-in events indicative of 'EvilTokens' phishing-as-a-service tradecraft. The rule monitors for initial token-grant events (device-code authentication or OAuth application consent) and subsequent successful sign-ins using existing SessionIds. This rule is designed as a foundational detection component for identifying session token replay, which allows adversaries to bypass MFA and password requirements by hijacking valid session tokens.
Detects anomalous sign-in behavior where the same Entra ID session or refresh token is reused from two geographically distant IP addresses within a short timeframe. This activity is correlated with a prior suspicious OAuth consent-grant or device-code authentication event on the same account, which is a common indicator of an 'EvilTokens' style session-token replay attack.
Detects a suspected ClickFix-style delivery mechanism where a user visits suspicious domains mimicking legitimate CLI tools (e.g., Gemini, Claude) via web browsers. The detection correlates this initial network access with subsequent suspicious Windows RunMRU activity and the spawning of shell processes (powershell.exe, cmd.exe) from explorer.exe using encoded or download-oriented command line arguments within a 5-minute window.
This rule detects potential Browser-in-the-Browser (BitB) phishing attacks by identifying suspicious browser pop-up behavior (using window.open flags, hidden address/toolbars) on non-identity-provider domains, followed shortly by credential submission patterns on the same device. This pattern mimics legitimate OAuth or SSO windows to harvest user credentials.
Detects the Windows Installer service (msiexec.exe) being launched by known remote access software processes like msra.exe (Microsoft Remote Assistance) or anydesk.exe. This behavior is often associated with unauthorized software installation or payload delivery via remote support tools.
Detects instances where the 'curl' utility is used to download files while simultaneously piping the output directly into a shell interpreter (bash/sh) or using download flags ('-o', '-O') in a way that suggests staging or immediate execution of remote scripts, often associated with force-flag bypass patterns.
This rule detects suspicious HTTP POST requests to a /collect endpoint that contain tracking parameters (visitorId, stage, variant, events) associated with 'ClickFix' social engineering campaigns. These campaigns typically trick users into copying and pasting malicious code by simulating error prompts or CAPTCHAs.
Detects unpacked Sauron Loader malware samples by identifying specific embedded configuration artifacts, including a fixed magic header value (0xbaadf00d), internal marker strings, and associated test identifiers for group and build IDs.
Detects malicious instruction-override payloads, hidden HTML comments, or obscured text (e.g., zero-font size) in third-party content ingested into LLM/RAG systems, commonly used for indirect prompt injection.
Detects the download of a dataset from an unapproved source that lacks hash verification, followed shortly by the launch of a model training process on the same host. This behavior is indicative of potential supply chain compromise or poisoning of the training data used in machine learning workflows.
