What is mullvad-crash-reporter.exe?
mullvad-crash-reporter.exe is the Mullvad VPN crash reporting tool. It activates when the Mullvad client experiences a crash and collects diagnostic data to help developers diagnose and fix issues. The reporter runs briefly, anonymizes data, and sends it to Mullvad for analysis.
It collects crash logs, stack traces, and basic system state from the Mullvad client, then transmits anonymized data to Mullvad servers for debugging. It does not access user files or reveal personal information beyond what's needed for crash analysis.
Quick Fact: Mullvad's crash reporter uses minimal data and runs only during crash events to protect user privacy.
Types of Mullvad Crash Reporter Behavior
- Crash Event Reporter: Activates when the Mullvad client or service crashes to collect diagnostics
- Background Diagnostic Stash: Gathers non-personal state information for debugging
- Network Submission Module: Sends anonymized crash data to Mullvad servers
- UI Feedback Helper: Provides user-visible status about crash reporting in the Mullvad app
- Error Telemetry Listener: Monitors for crash-related events to trigger reporting
- Cleanup Task: Removes temporary crash data after successful submission
Is mullvad-crash-reporter Safe?
Yes, mullvad-crash-reporter.exe is safe when it is the legitimate file from Mullvad VPN downloaded from official sources (mullvad.net or pre-installed by the vendor).
Is mullvad-crash-reporter.exe a Virus or Malware?
The real mullvad-crash-reporter.exe is NOT a virus. Malware may imitate names; verify with location and digital signature.
How to Tell if mullvad-crash-reporter.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\Mullvad VPN\ and the file name should be mullvad-crash-reporter.exe. Any other path or name is suspicious.
- Digital Signature:: Right-click the binary in Explorer → Properties → Digital Signatures. Should show a valid signature from Mullvad VPN AB.
- Resource Usage:: Normal usage is 0-3% CPU and 5-25 MB memory. Persistently high usage outside of crash events is suspicious.
- Behavior:: Should only run in response to a Mullvad crash or when explicitly invoked by the Mullvad UI.
Red Flags: If mullvad-crash-reporter.exe is located outside the Mullvad VPN install folder, runs without a Mullvad crash, lacks a valid signature, or uses excessive resources constantly, scan with antivirus and consider reinstalling Mullvad from official sources.
