This rule monitors network, DNS, and HTTP activity to identify connections to known infrastructure associated with the ClickFix social engineering campaign and Vidar infostealer malware. The rule correlates device network events, HTTP request events, and DNS queries against a list of known malicious domains, IP addresses, and URL patterns used for C2, staging, and lures.

This rule detects potential staging activity for ClickFix or Vidar malware campaigns. It identifies the creation of files or folders in directories mimicking Windows Diagnostics infrastructure (WDI) or known payload paths, correlated with the execution of suspicious PowerShell commands or archive-related utilities within a 30-minute window on the same device.

This rule detects potential command and control (C2) communication and malicious process execution associated with the Vidar stealer malware. It monitors both network connections and process command lines for indicators of known Telegram C2 channels and secondary Steam community profile C2 infrastructure. The rule specifically highlights activity originating from processes other than common web browsers to identify suspicious automated beaconing or control.

This rule detects malicious activity related to the exploitation of MpDlpService.exe. It looks for the execution or presence of known malicious file hashes associated with this threat, including a P-stage script, payload files, and a malicious mpclient.dll. Additionally, it identifies instances where the legitimate MpDlpService.exe binary is executed from a non-standard, suspicious directory, which is a common indicator of side-loading or persistence techniques.

Detects a sequence of activity characteristic of lateral movement and credential theft: the deployment or execution of PsExec service followed by the use of Windows utilities (vssadmin, ntdsutil, esentutl) to perform Volume Shadow Copy-based extraction of the NTDS.dit database or SYSTEM hive on the same host.

Detects potential credential reuse attacks such as Pass-the-Hash, Pass-the-Ticket, or Overpass-the-Hash. The rule identifies a 'NewCredentials' logon (e.g., runas /netonly) followed by a network or remote interactive logon to a target system (such as a domain controller) by the same user, without an interactive logon session occurring between the events, which is indicative of using stolen credentials to move laterally.

Detects two distinct behaviors indicative of potential credential theft or lateral movement: DCSync-style Active Directory replication requests identified via Event ID 4662 with specific replication GUIDs, and high-volume SMB traffic originating from Domain Controllers or DC-adjacent hosts, which may indicate unauthorized data access or credential dumping activities.

Detects HTML smuggling files identified as 'FlipBook' lures, commonly used in device-code phishing campaigns. These lures utilize client-side JavaScript for AES-GCM decryption, extensive comment-based obfuscation, and specific junk-padding techniques to bypass security controls and trick users into providing credentials.
