Detects access to Firefox profile database files (cookies.sqlite, places.sqlite, permissions.sqlite) by suspicious processes that are masquerading as legitimate system maintenance or update utilities. This rule specifically targets known masquerading process names (UpdateAssistant.exe, AppUpdateHelper.exe, SysMaintenance.exe) while excluding the legitimate firefox.exe process and its installation directory.
Detects unauthorized processes (e.g., cmd.exe, powershell.exe, node.exe) accessing sensitive web browser files like 'Login Data' or 'Cookies' in common browser directories. This behavior is indicative of credential theft or data exfiltration attempts.
Detects commandline keywords indicative of potential usge of the tool WinPwn. A tool for Windows and Active Directory reconnaissance and exploitation.
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 instances where processes other than the primary web browsers (Chrome, Brave, Firefox) create, rename, or modify sensitive browser data files like 'Cookies' or 'Login Data'. This behavior is indicative of credential theft or data exfiltration attempts where an adversary is accessing browser-stored information.
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 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 access to Firefox profile database files (cookies.sqlite, places.sqlite, permissions.sqlite) by suspicious processes that are masquerading as legitimate system maintenance or update utilities. This rule specifically targets known masquerading process names (UpdateAssistant.exe, AppUpdateHelper.exe, SysMaintenance.exe) while excluding the legitimate firefox.exe process and its installation directory.
Detects unauthorized access to Chrome and Microsoft Edge login data files. This behavior is indicative of credential theft, frequently observed in info-stealer malware such as Stealer/1.0, which attempts to extract stored browser credentials for exfiltration.
This rule detects suspicious activity involving common web browser credential files (Cookies, Login Data) being read, created, modified, or renamed by processes associated with iCloud synchronization paths on macOS. This behavior is indicative of potentially malicious processes attempting to exfiltrate browser-stored session information or credentials.
Detects Node.js or Electron processes executing from suspicious paths (e.g., Temp, Roaming) while interacting with web browser credential files or executing commands consistent with automated credential dumping tools.
Detects unauthorized processes attempting to read sensitive browser credential and session data (e.g., 'Login Data', 'Cookies', 'Local State', 'cookies.sqlite', 'logins.json') located in common browser profile paths. This behavior is highly indicative of information-stealing malware attempting to extract saved passwords and session cookies for account hijacking and 2FA/SSO bypass.
Detects scriptblock text keywords indicative of potential usge of the tool WinPwn. A tool for Windows and Active Directory reconnaissance and exploitation.
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 instances where processes other than the primary web browsers (Chrome, Brave, Firefox) create, rename, or modify sensitive browser data files like 'Cookies' or 'Login Data'. This behavior is indicative of credential theft or data exfiltration attempts where an adversary is accessing browser-stored information.
Detects instances where the Google Chrome browser is executed with flags that disable the sandbox security feature, such as --no-sandbox and --allow-no-sandbox-job. This configuration is often used by adversaries to facilitate credential dumping from the browser by bypassing sandbox restrictions that typically prevent unauthorized process memory access.
Detects behavioral indicators associated with the ChocoShell malware, a fileless PowerShell-based infostealer. The rule monitors for malicious command-line activity including AMSI bypass, credential theft from Token Broker and WLAN profiles, disabling of Microsoft Defender signatures, and communication with local API endpoints typical of the CornFlake controller.
This rule detects suspicious activity involving common web browser credential files (Cookies, Login Data) being read, created, modified, or renamed by processes associated with iCloud synchronization paths on macOS. This behavior is indicative of potentially malicious processes attempting to exfiltrate browser-stored session information or credentials.
Detects unauthorized, non-browser processes accessing sensitive Chromium-based browser credential files (e.g., 'Local State', 'Login Data', 'Cookies') followed by suspicious outbound network connections. This pattern is characteristic of credential-stealing malware (infostealers) like Amatera, Lumma, and Remus.
This rule detects suspicious activity involving common web browser credential files (Cookies, Login Data) being read, created, modified, or renamed by processes associated with iCloud synchronization paths on macOS. This behavior is indicative of potentially malicious processes attempting to exfiltrate browser-stored session information or credentials.
