Detects HijackLoader attempting to perform anti-virtual machine (VM) checks by querying for VirtualBox-specific registry keys from a PowerShell process that also initiates a network connection. This combination of behaviors is indicative of sandbox evasion.
Detects the ITarian RMM service (RmmService.exe) spawning a child process from various suspicious directories commonly used for malware staging. This behavior is associated with adversaries using ITarian for post-exploitation activities, such as dropping additional malware.
Detects the creation of a symbolic link in the Windows Defender Platform directory. This is a technique used to hijack the execution flow of Windows Defender, forcing it to run from an attacker-controlled location upon service restart or update.
Detects attempts to replace the legitimate UEFI bootloader (bootmgfw.efi) with a malicious one by creating a backup (.old file) and modifying the original. This is a critical persistence technique used by the HybridPetya ransomware.
This detection identifies the installation of known malicious Chrome extensions associated with the "Madgicx Plus" campaign, which targets Meta advertisers to steal credentials and hijack sessions. The rule looks for registry modifications that include the specific IDs of these malicious extensions.
Detects when 'msimg32.dll' is loaded from a non-standard directory, which can be an indicator of DLL hijacking.
Detects potential DLL side-loading where the legitimate Palo Alto Networks executable 'PanGpHip.exe' is launched from a non-standard directory and loads 'libwaapi.dll' from the same path. This behavior is consistent with the technique described in the dmpdump report, where an LNK file executes the legitimate application to load a malicious DLL.
Detects the loading of the vulnerable RTCore64.sys driver. This driver is exploited by threats like kkRAT to disable AV/EDR security callbacks as part of a Bring Your Own Vulnerable Driver (BYOVD) attack.
Detects modification of common macOS shell configuration files, a technique used by the ChillyHell backdoor for persistence.
Detects a sequence of events indicative of Process Doppelgänging, a technique used by APT37. This rule identifies a process creating a legitimate Windows utility and then immediately injecting code into it, which is characteristic of creating a process in a suspended state for injection.
