This rule detects the manual instantiation of PowerShell ScriptBlock objects via the '::Create' method. This technique is commonly used by malicious PowerShell scripts and offensive security tools to bypass traditional command-line logging by executing code dynamically in memory, often avoiding disk-based signatures.
Detects post-infection data harvesting behavior associated with PureLogs Stealer. The rule monitors specific LOLBins (.NET binaries) and suspected masqueraded payloads (e.g., syscall.exe) as they attempt to access browser credential, cookie, or web data files from Google Chrome, Microsoft Edge, and Mozilla Firefox. It also tracks the creation of these suspicious processes when invoked by scripting interpreters like PowerShell, wscript, or cscript.
Detects a single host or account interacting with a high volume of archive (PST/OST) and document files, or initiating mailbox exports within a short window, which is often indicative of mass data staging and collection prior to exfiltration.
Detects a suspicious correlation between the registration of new authentication methods or application integrations and the subsequent modification of Conditional Access policies within a 2-hour window. This behavior is indicative of the activation phase of a TrustSink attack, where an adversary sets up a malicious MFA provider and forces its use by expanding Conditional Access policy scope.
Detects a sequence of PowerShell commands consistent with the VelvetCake reconnaissance module, including enumeration of antivirus software via SecurityCenter2, system information, IP configurations, running processes, recent files, and drive mapping within a short timeframe.

Detects Azure AD sign-in events where Multi-Factor Authentication (MFA) was reportedly satisfied by an External Authentication Method (EAM) claim without evidence of a traditional secondary authentication challenge. This behavior is indicative of a 'TrustSink' technique where a rogue or compromised OIDC provider injects a spoofed assertion of MFA success into the authentication token.
Detects outbound network traffic (TLS and HTTP) destined for the Telegram Bot API (api.telegram.org). This pattern is often used by malicious actors for Command and Control (C2) communication, bot notifications, or data exfiltration, leveraging the legitimate Telegram infrastructure to hide malicious activity.
Detects the initialization sequence of the ORAX command-and-control framework, characterized by a handoff via a spoofed Cloudflare verification page followed by a WebSocket upgrade request.
Detects potential session hijacking of a Claude SaaS account by identifying sign-ins from unrecognized IP addresses followed by a high-volume burst of API usage or message activity that deviates from the account's established baseline.
