Detects outbound network traffic containing the string 'Secret: ', which indicates potential sensitive data exfiltration. The rule specifically targets the use of netcat-like behavior directed toward external endpoints, which are commonly associated with tunneling services like ngrok used to bypass network egress restrictions.
Detects unauthorized creation or modification of persistent-state files used by AI agents (e.g., AGENTS.md, MEMORY.md). Such files can be poisoned to manipulate the AI agent's objective knowledge or behavior if the content is sourced from untrusted external inputs like email rather than explicit user instructions.
Detects a modified Dockerfile or build script installing netcat and building/pushing a multi-arch image via docker buildx, consistent with backdoored container image creation
Detects the deployment of an Azure Container Instance (ACI) where the image source or container name matches identified indicators of a potentially compromised registry or unauthorized deployment pattern.
Detects potential persistence mechanisms that mimic or leverage the Microsoft OneDrive update process. This includes the creation or modification of scheduled tasks containing 'OneDrive Update' in the command line using tools like schtasks or PowerShell, as well as modifications to the HKCU OneDrive environment registry key, a behavior associated with the GigaWiper malware.
Detects potential User Account Control (UAC) bypass attempts using the PowerShell 'Start-Process' cmdlet with the 'runAs' verb, which requests administrative privileges for a new process. The rule also includes a specific check for command-line artifacts associated with the 'wipe32' malware campaign, which utilizes this method for privilege escalation.
Detects the use of reg.exe to modify registry keys associated with Windows crash-dump settings and automatic reboot policies. Such modifications are indicative of attempts to inhibit system recovery and hinder incident response analysis, often associated with wiper malware such as GigaWiper.
Detects the creation of PNG screenshot files with a specific directory naming convention (numeric subdirectory containing numeric filename) associated with the GigaWiper destructive malware.
Detects the creation of files within the 'ProgramData\output\' directory, a pattern associated with the GigaWiper malware which utilizes this location to store captured screen recordings or screenshots during its operation.
Detects the execution of GigaWiper malware registry modules. The rule monitors command-line activity for specific binary names associated with the GigaWiper malware family that perform registry modifications, such as key creation or deletion.
