Detects successful Azure AD sign-ins where the user agent identifies as a Python requests library version (2.33.1 or 2.34.2) that has not been observed for that specific user account in the preceding 14 days. This behavior is indicative of anomalous automated or scripted access.
Detects sessions using shared Grafana service account tokens that perform both read-only and action-capable tool operations without confirmed prior authentication. This behavior is indicative of an unauthenticated or spoofed session leveraging a service account's excessive permissions, bypassing standard authentication flows.
Detects nm_host.exe (PEEP native messaging host binary) spawned by Chrome/Edge, tightened to require either the known PEEP extension ID in the native-messaging invocation command line or the distinctive com.peep.lab host path.
Detects unauthorized processes accessing sensitive web browser files (login data, cookies, local state) from suspicious or non-standard paths. This is a common behavioral pattern for infostealers attempting to exfiltrate user credentials and browser session tokens.
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 the creation or renaming of files with an 'ELAM' (Early Launch Anti-Malware) naming convention pattern outside of standard system driver directories, performed by processes that are not verified Microsoft-signed binaries. This may indicate an attempt to install or masquerade as a boot-start driver for persistence or subverting security controls.
Detects the creation of Object Manager symbolic links that redirect the Windows Defender 'WD_SCAN' object to a loopback UNC share path. This behavior is indicative of a symlink exploitation technique (ShieldCrash/CVE-2026-69414) used to manipulate Windows Defender or associated scan operations by redirecting them to an adversary-controlled or loopback-hosted target.
Detects the creation of Object Manager symbolic links that redirect the Windows Defender 'WD_SCAN' object to a loopback UNC share path. This behavior is indicative of a symlink exploitation technique (ShieldCrash/CVE-2026-69414) used to manipulate Windows Defender or associated scan operations by redirecting them to an adversary-controlled or loopback-hosted target.
Detects suspicious file activity within directories named 'ShieldCrash' followed by a cloud provider registration or placeholder creation event within a 5-minute window. This behavior is indicative of unauthorized software or an adversary attempting to stage data for exfiltration or create persistent storage aliases outside of legitimate cloud client applications.
This rule detects suspicious file operations (creation, modification, or renaming) initiated by MsMpEng.exe (Microsoft Defender Antivirus) involving specific indicators related to ELAM (Early Launch Anti-Malware) or 'ShieldCrash' components. These indicators often suggest tampering attempts or the presence of tools designed to interfere with Defender's security operations by targeting its configuration, staging, or protected storage locations.
