![]() Monitor for newly constructed files that may forge web cookies that can be used to gain access to web applications or Internet services. CPL files can be executed directly via the CPL API function with just the latter Rundll32 command, which may bypass detections and/or execution filters for control.exe. When executed from the command line or clicked, control.exe will execute the CPL file (ex: control.exe file.cpl) before Rundll32 is used to call the CPL's API functions (ex: rundll32.exe shell32.dll,Control_RunDLL file.cpl). ![]() Restrict storage and execution of Control Panel items to protected directories, such as C:\Windows, rather than user directories. cpl files by using application control tools, like Windows Defender Application Control, AppLocker, or Software Restriction Policies where appropriate. Identify and block potentially malicious and unknown. Reaver drops and executes a malicious CPL file as its payload. ![]() InvisiMole can register itself for execution and persistence via the Control Panel. Įmber Bear has used control panel files (CPL), delivered via e-mail, for execution. CPL files not exporting CPlApplet are not directly executable. Even when these registered DLLs do not comply with the CPL file specification and do not export CPlApplet functions, they are loaded and executed through its DllEntryPoint when Control Panel is executed. Control Panel items, specifically CPL files, may also bypass application and/or file extension allow lists.Īdversaries may also rename malicious DLL files (.dll) with Control Panel file extensions (.cpl) and register them to HKCU\Software\Microsoft\Windows\CurrentVersion\Control Panel\Cpls. Malicious Control Panel items can be delivered via Phishing campaigns or executed as part of multi-stage malware. Control Panel items can be executed directly from the command line, programmatically via an application programming interface (API) call, or by simply double-clicking the file. For ease of use, Control Panel items typically include graphical menus available to users after being registered and loaded into the Control Panel. The Windows Control Panel process binary (control.exe) handles execution of Control Panel items, which are utilities that allow users to view and adjust computer settings.Ĭontrol Panel items are registered executable (.exe) or Control Panel (.cpl) files, the latter are actually renamed dynamic-link library (.dll) files that export a CPlApplet function. Adversaries may abuse control.exe to proxy execution of malicious payloads.
