Is terraform-updater.exe a Virus or Malware?

The real terraform-updater.exe is NOT a virus. However, malware may masquerade with similar names; always verify signatures.

How to Tell if terraform-updater.exe is Legitimate or Malware

File Location:: Must be in C:\Program Files\HashiCorp\Terraform Updater\terraform-updater.exe or C:\Program Files (x86)\HashiCorp\Terraform Updater\terraform-updater.exe. Any other path is suspicious.
Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show signer "HashiCorp, Inc." with a valid certificate.
Resource Usage:: Normal usage is 1-5% CPU and 20-60 MB RAM while idle. Constantly high or unknown processes are suspicious.
Behavior:: Updater should run only when updates are available or on a scheduled task. Continuous foreground launches may indicate tampering.
