Detects post-exploitation persistence artifacts on Windows endpoints managed by N-able N-central consistent with abuse of CVE-2026-18577, including a new Windows service named Cloudflared, registry Services key creation for Cloudflared, a file named svchost.exe written under a user's Documents folder, or process execution of cloudflared.exe or a Documents-located svchost.exe.
Detects post-exploitation persistence artifacts on Windows endpoints consistent with abuse of CVE-2026-18577.
The following analytic identifies processes running from file paths not typically associated with legitimate software. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on specific process paths within the Endpoint data model. This activity is significant because adversaries often use unconventional file paths to execute malicious code without requiring administrative privileges. If confirmed malicious, this behavior could indicate an attempt to bypass security controls, leading to unauthorized software execution, potential system compromise, and further malicious activities within the environment.
Detects the loading of the 'user32.dll' library into a process named 'firefox.exe' where the process is either unsigned or executing from a suspicious location like 'ProgramData'. This pattern is consistent with the behavior of BabylonRAT, which masquerades as the Firefox browser to perform keylogging by hooking system APIs.
Detects the execution of a process named 'firefox.exe' that is running from a path other than the standard Mozilla Firefox installation directory. This is a common technique used by malware to masquerade as a legitimate web browser.
Detects instances of 'firefox.exe' executing from locations other than the standard Mozilla installation directories, such as AppData, Temp, Downloads, or ProgramData. Additionally, the rule validates if the binary is digitally signed by Mozilla. This behavior is indicative of a masquerading attempt, where an attacker runs a malicious executable disguised as Firefox.
Detects instances of 'firefox.exe' executing from locations other than the standard Mozilla installation directories, such as AppData, Temp, Downloads, or ProgramData. Additionally, the rule validates if the binary is digitally signed by Mozilla. This behavior is indicative of a masquerading attempt, where an attacker runs a malicious executable disguised as Firefox.
Detects instances where a process named firefox.exe is running from a non-standard location or includes keywords indicative of keylogging activity such as 'SetWindowsHookEx', 'GetAsyncKeyState', 'GetKeyState', or 'keylog'. This is a common behavioral indicator for the BabylonRAT malware.
Detects execution of the suspicious installer 'OrionQuests-Setup.exe' or the creation of shortcut (.lnk) files associated with this specific executable name. This activity is indicative of potential malicious installer behavior, likely used to distribute malware or drop persistent components.
Detects execution of the suspicious installer 'OrionQuests-Setup.exe' or the creation of shortcut (.lnk) files associated with this specific executable name. This activity is indicative of potential malicious installer behavior, likely used to distribute malware or drop persistent components.
Detects instances of 'firefox.exe' executing from locations other than the standard Mozilla Firefox program directories, a technique used by BabylonRAT and other malware to masquerade as a legitimate browser application.
Detects the creation of Windows Run registry keys by a process named 'firefox.exe' that originates from a non-standard file path. This behavior is indicative of BabylonRAT attempting to establish persistence by masquerading as the Mozilla Firefox browser.
Detects the execution of a process named 'firefox.exe' from a directory other than the standard Mozilla Firefox installation path ('C:\Program Files\Mozilla Firefox' or 'C:\Program Files (x86)\Mozilla Firefox'). This behavior is commonly associated with the BabylonRAT malware, which masquerades as the legitimate Firefox browser to hide its presence and facilitate initial infection.
Detects the execution of a process named 'firefox.exe' from a directory other than the standard Mozilla Firefox installation path ('C:\Program Files\Mozilla Firefox' or 'C:\Program Files (x86)\Mozilla Firefox'). This behavior is commonly associated with the BabylonRAT malware, which masquerades as the legitimate Firefox browser to hide its presence and facilitate initial infection.
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 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.
This rule detects the presence or execution of a file named 'GlobalProtect.exe' within the Palo Alto GlobalProtect directory. It focuses on identifying potentially masqueraded or unauthorized binaries by monitoring file events and associated process execution. This pattern is commonly used by attackers to disguise malicious files as legitimate security software to evade detection.
Detects NSIS installer/archive contents bundling the specific unsigned/renamed UpdateAssistant.exe (aka AppUpdateHelper.exe) payload alongside its associated staged runtime DLLs and known malicious file paths/hashes used as cover noise for DLL sideloading staging
KQL Query from file: Cloudflared Persistence & svchost.exe Masquerading Post-N-central CVE-2026-18577
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 the Warden.dll companion DLL shipped as part of the ShieldCrash (CVE-2026-69414) exploit chain, tightened to require an unsigned/unknown publisher or a suspicious install path alongside the generic filename
