Vidar Stealer Chrome Process Fork via NtCreateProcessEx for ABE Key Extraction
This rule detects suspicious attempts by non-browser processes to access Google Chrome's process memory or create threads within it. This behavior is often indicative of process injection techniques used by malware to hook into or extract data from the browser, potentially for credential theft or session hijacking. The rule specifically looks for API calls like OpenProcess, NtCreateProcessEx, CreateRemoteThread, NtReadVirtualMemory, and ReadProcessMemory targeting 'chrome.exe' by processes other than Chrome itself or its legitimate update/driver executables.
