Q100689: Katana downloads blocked in web browsers



This article provides an update on the ongoing technical difficulties with Katana downloads mentioned on our main Katana product download page here: https://www.foundry.com/products/katana/download 



Foundry is aware that Google Safe Browsing is currently flagging our Katana installers as containing malware, blocking downloads in the Chrome and Firefox browsers.  

A thorough investigation was made into this finding, with our installer being placed under the scrutiny of multiple alternative signature based and also next-gen antivirus tools - all of which found no trace of any malware.  

As such we are confident this finding is a false positive.

Our Engineering teams have compared the signatures and detection logic utilised by VirusTotal, Windows Defender, CrowdStrike, Hitman Pro and MalwareBytes against the Katana binary originally flagged by Google, and these scans have passed successfully.

We would invite any customers who have observed these Google Safe Browsing warnings to also scan using other tools - such as Windows Defender, MalwareBytes or Hitman Pro - to self-certify that this finding as a false positive.



We started the appeal process with Google immediately. However this can take up to 30 days for Google to process during which regular access to Katana downloads will be interrupted.

If you've submitted your email address using the form here https://www.foundry.com/products/katana/download, then we will notify you once the issue is resolved.  



To download a Katana version during this period you can use one of the options below:

  • Safari & Edge - The Safari browser on macOS and Edge browser currently do not block our regular download path.
  • FTP - We have established a secure FTP server to provide Katana installers for download, you can connect to this service using the following details:
    • Server: katanadownload.foundry.com
    • Port: 21 - TLS encryption is in use despite the plain FTP port, modern FTP clients should auto-resolve the TLS connection.
    • Username: download@katana.foundry.com
    • Password: Katana2024!

NOTE: In order to access our secure FTP server you will need to use your preferred FTP client and connect using the details above. If you don’t use an FTP client you should contact your system administrator for guidance.

    We're sorry to hear that
