This rule detects the creation of scheduled tasks that attempt to masquerade as legitimate Google Chrome Update tasks. It flags tasks that use the 'Google Chrome Update' name but do not follow the standard naming convention (which typically includes 'GoogleUpdateTaskMachine') or tasks that initiate suspicious actions using scripting engines (like PowerShell, cmd.exe, mshta, etc.) rather than the signed Google update binary.
Detects the execution or creation of files masquerading as Mozilla Firefox components (e.g., firefox.exe) located within non-standard, suspicious directories under 'ProgramData'. The rule further refines these alerts by identifying instances where the file lacks a valid Mozilla digital signature or contains an incorrect company name in its metadata.
Detects instances where a process named firefox.exe attempts to establish persistence via Windows Registry Run keys or Windows Task Scheduler while operating outside of standard Mozilla Firefox installation directories. This behavior is indicative of masquerading techniques used by threats such as BabylonRAT to maintain persistence under the guise of a common web browser.
Detects unauthorized access to sensitive browser credential files (e.g., Chrome 'Login Data', Firefox 'logins.json' and 'key4.db') by processes other than legitimate browser executables. This behavior is indicative of credential harvesting attacks, such as those performed by BabylonRAT.
Detects instances where a process masquerading as Firefox (executing outside of legitimate program directories) attempts to modify the Windows 'hosts' file. This behavior is indicative of BabylonRAT or similar malware attempting to redirect network traffic to malicious domains by tampering with local DNS resolution.
Detects instances where a process masquerading as Firefox (executing outside of legitimate program directories) attempts to modify the Windows 'hosts' file. This behavior is indicative of BabylonRAT or similar malware attempting to redirect network traffic to malicious domains by tampering with local DNS resolution.
Detects potential keylogging behavior by identifying a process masquerading as firefox.exe that is operating from an unauthorized directory while utilizing keyboard hooking (SetWindowsHookEx) or polling (GetAsyncKeyState) APIs, a technique consistent with the BabylonRAT malware.
Detects the use of PowerShell to load .NET assemblies into memory using the Assembly.Load method. This technique is often employed by adversaries to execute malicious payloads reflectively, avoiding the creation of files on disk.
Detects when a user who has successfully authenticated to a system is subsequently added to the 'Domain Admins' group within a 15-minute window. This behavior often indicates an adversary performing privilege escalation after gaining initial access to an account.
Detects unauthorized database activity targeting Nacos configuration tables, characterized by the use of MySQL's AES_ENCRYPT function to encrypt records, followed by the deletion of original table data or the issuance of a ransom demand. This behavior is indicative of extortion attempts or agentic ransomware targeting web application backends.
