.. if you want to be safe, block all OUTGOING Traffic by a Firewall or local DNS Server and use a Proxy with Auth Mechanism!

Nextcloud Owncloud Calling Home

I did a deeper firewall test on my fresh installed OpenWRT Router and activated a „Ads Blacklist“ after this my owncloud Share Login loops!

Result:

  • Seems that some IP’s of the „Update Check Tool“ Servers, which is installed inside the PHP-Kit is blacklisted.
  • So it seems the Code calls home!  With this option its possible to count and collect IPs of Setups! Perhaps checkout unpatched Versions!
  • I didn’t check deeper, but the behavior was clear without viewing the codes.

After publish this Info via Twitter:

REMARKS:

  • No Company / Developer works for „free“
  • After Setup of PHP-Kits do a IP Firewall Traffic checkout
  • If you don’t need the PHP Kit reachable via Internet block the IP Device at your Router from Internet Access!
  • Prefer Standard Tools like SFTP/SCP with Key Auth to transfer Files, less unsecure cause only one application active!!
  • PHP Kits Logins can often be scanned by Search Indexes by „Search by Title“ of the Login Webinterface!!

For me i decided to purge the package and use System Standard Tool „SFTP with SSH Key Auth“ and on my Phone a Totalcommander with SFTP Plugin!
