Detects the loading and service creation of the CcProtect/Alinubx kernel driver, a known technique for Bring Your Own Vulnerable Driver (BYOVD) attacks. The rule identifies suspicious characteristics such as file name mismatches, unauthorized product/company signatures, and the creation of services associated with this malicious driver family (e.g., NvFsFilter) to facilitate EDR/AV termination or privilege escalation.
This rule monitors for network traffic related to known fake GitHub pages and malicious loader sites impersonating LastPass Authenticator. It detects attempts to access specific malicious domains and organization pages on GitHub, as well as the delivery of malicious pages containing spoofed trust badges and branding, commonly used in phishing campaigns.
This rule detects the execution of 'vsdbg.exe', the Visual Studio Remote Debugger, from non-standard directories (e.g., Downloads, AppData, Temp, ProgramData) or in conjunction with the creation of 'vsdbg.dll' files. Adversaries may utilize this debugger for remote code execution or to bypass security controls by masquerading as a legitimate development tool.
This rule detects successful logon events (Event ID 4624) or special logon events (Event ID 4648) with specific logon types (7: NetworkCleartext, 8: NewCredentials, 9: Network, 11: CachedInteractive) that occur within 24 hours of a user registration event on the same host. This pattern may indicate suspicious account usage shortly after account creation or registration on a device.
This rule detects authentication events using the Device Code OAuth flow where the user account name contains keywords associated with sensitive or privileged roles (such as 'finance', 'admin', 'accounts'), originating from non-private (external) IP addresses. This activity is indicative of potential device code phishing attacks targeting sensitive user accounts.
Detects the creation or modification of inbox and transport rules in Office 365 that perform automatic email actions such as redirecting, forwarding, deleting, or marking emails as read, especially when targeting keywords related to sensitive information (e.g., invoice, payment, vendor, bank). This behavior is often associated with email account compromise and data exfiltration or persistence strategies.
Detects the creation or modification of email inbox rules that perform actions such as forwarding, deleting, or moving messages combined with keywords often associated with financial fraud, business email compromise (BEC), or credential harvesting. Adversaries often use these rules to hide communications, redirect financial emails, or automate data exfiltration.
This rule detects the potential use of parent process spoofing (PPID spoofing) where a PowerShell process is spawned with 'explorer.exe' as its parent. This technique, often executed via the 'PROC_THREAD_ATTRIBUTE_PARENT_PROCESS' attribute in a 'CreateProcessW' call, is used by adversaries to mask the true origin of the PowerShell process and evade behavioral detection.
Detects unauthorized access attempts to browser credential files (such as Login Data, key4.db, and cookies) by non-browser processes. This behavior is indicative of the Rapuncel infostealer, which harvests stored browser credentials after attempting to disable or bypass security solutions.
