Download TearSt0pper

Protect systems from future infection by WanaCry with TearSt0pper and CONTINUE TO PATCH MS17-010.

Important notes:

  • Systems will have to be running TearSt0pper to prevent active exploitation. TearSt0pper will have to be re-run each time the machine is rebooted.  This can be done by using an autorun key
  • TearSt0pper is not actually preventing exploitation.  By the time TearSt0pper springs into action, the host has already been exploited. TearSt0pper just prevents the ransomware from encrypting files.
  • Future versions of ransomware and/or malware deployed via MS17-010 may use different mutexes.  Rendition will stay abreast of the latest mutexes and release new versions.  If you sign up for email notification when you download, you will be notified when new version are available.
  • TearSt0pper cannot be used to decrypt files from a system where files have already been encrypted. TearSt0pper does not disinfect a system, it merely uses the malware's logic against it.
  • TearSt0pper works for WinXP and forward, please contact us if you require earlier OS support.

Download TearSt0pper (and register for update notifications) here.  As Rendition is reasonably certain that WCry will mutate to include additional payloads, we highly recommend that you register for update notification so we can let you know when new versions of TearSt0pper are available. Your information will never be shared with a third party (because we hate that too).
