Detects the installation or modification of a browser extension (manifest.json file creation) followed by network activity from the browser to trusted AI assistant domains within a five-minute window. This behavior is indicative of potentially malicious browser extensions or content scripts being introduced to intercept or manipulate user interaction with AI services.

Detects the 'Comet.exe' process, associated with the Perplexity Comet AI agent, accessing sensitive system files or configuration directories outside its expected scope. This pattern of file interaction is characteristic of unauthorized data collection or exfiltration attempts, specifically linked to the BragJack threat activity.

Detects browser activity where a user agent navigates to common webmail services (Gmail, Outlook) followed quickly by network traffic to potentially malicious external infrastructure or non-standard endpoints, suggesting unauthorized email content exfiltration.

Detects alerts that reference specific CVEs historically exploited by the threat group QTFY against internet-facing applications, including common vulnerabilities in Pulse Secure, FortiOS, Citrix ADC, Exchange, F5 BIG-IP, Log4Shell, and others, when the alert severity is Medium or High and contains indicators of exploit or initial access.
Detects the suspicious registration of a Cloud Filter provider callback using staging paths and naming conventions associated with the ShieldCrash (CVE-2026-69414) exploit. The rule monitors DeviceEvents for cloud provider activity that originates from unsigned or untrusted binaries, excluding known-legitimate cloud synchronization clients.
Detects successful exploitation attempts targeting Vite development servers via chained access-control bypass vulnerabilities (CVE-2025-30208, CVE-2025-31125, CVE-2024-45811). The rule identifies malicious GET requests using the /@fs/ endpoint with specific query parameters, resulting in a successful HTTP 200 response, while originating from non-internal IP addresses.
