Detects unauthorized processes attempting to access sensitive web browser files (login data, cookies, configuration) located in Chrome or Firefox profile directories. The detection excludes known browser-related processes and system processes, focusing on third-party or potentially malicious utilities that could be used to harvest credentials stored in these local files.

000
Detects instances where browser processes or related credential files are accessed or targeted by process termination (e.g., taskkill.exe) followed by attempts to access sensitive files like Login Data, logins.json, or key4.db. This pattern is indicative of credential theft from web browsers.

105
Detects instances where 'ERAAgent.exe', part of the ESET Remote Administrator agent, loads the 'dpapi.dll' library from a location outside of standard Windows System directories (System32 or SysWOW64). Furthermore, the rule flags this behavior if the loaded 'dpapi.dll' file is either unsigned or contains an untrusted digital signature, which may indicate a malicious DLL side-loading or masquerading attempt to access protected system credentials.

Detects processes that access sensitive browser credential or cookie files (e.g., Login Data, Cookies) followed by network activity within a 10-minute window, which is a common behavior pattern of information-stealing malware such as Amatera or ACR Stealer.

Detects PEEP credential/session theft via the native-messaging bridge, native host registration, staged CRX, or extension ID references. The nm_host.exe branch is now anchored to the known PEEP extension IDs (primary and alternate build) or the com.peep.lab path, rather than firing on any nm_host.exe spawned by a browser.

This rule monitors for three distinct suspicious behaviors on Windows endpoints: the addition of executable files from temporary or user-writable directories to Windows registry run keys for persistence, the creation of repeated hidden log or data files in AppData directories, and unsigned processes accessing browser-related credential storage files.
