Detects sign-in events in Entra ID where the OAuth 2.0 device authorization grant (device code) flow is utilized. This flow is a common vector for phishing attacks designed to steal tokens by tricking users into authenticating on a secondary device, potentially bypassing MFA.
Detects attempts to modify, disable, or query Microsoft Defender configuration settings or status using legitimate Windows management tools (PowerShell/WMI) by processes other than authorized Defender executables (MsMpEng.exe, MpCmdRun.exe).
Detects usage of the net1.exe utility to list members of the local 'Administrators' group in various languages. This technique is often used by adversaries for local system discovery during the reconnaissance phase.
Detects the creation or modification of Registry keys within 'Image File Execution Options' (IFEO) intended to associate a debugger with security-critical or monitoring binaries (e.g., Sysmon, Filebeat). This technique is used for defense evasion and persistence by intercepting or preventing the execution of security tools.
Detects attempts to terminate or delete security-related services and logging agents, such as Sysmon, Filebeat, and various endpoint protection agents, using legitimate Windows system utilities like taskkill, sc, or wmic.
Detects network traffic directed towards Telegram shortened URLs (t.me) which is a common command-and-control (C2) communication channel used by Vidar and other malware families to exfiltrate data or retrieve instructions.
Detects modifications to the WDigest 'UseLogonCredential' registry key. Enabling this setting (setting it to 1) forces the WDigest SSP to store plaintext credentials in memory, which facilitates easier credential harvesting by attackers using memory dumping techniques.
Detects the use of the wevtutil.exe utility to clear multiple Windows event logs simultaneously. This is a common defense evasion technique used by attackers to hide malicious activity by deleting security, system, application, or setup event logs.
Detects the creation or execution of a scheduled task named 'CreateObjectTask' via schtasks or PowerShell, which is associated with spawning 'dllhost.exe' as a child process under high-privileged parent processes (svchost, taskeng, or schtasks). This behavior is indicative of potential COM hijacking or privilege escalation techniques leveraging system tasks.
Detects web browser processes (e.g., Chrome, Edge, Firefox) spawned by parent processes that are not typical for web browser execution. This behavior is often associated with malware (such as infostealers) using unconventional process spawning to inject code or perform credential theft.
