The security company RSA has published a new report which claims that a commercial Chinese VPN provider is using hacked Windows servers in order to allow their clients to bypass the Chinese Firewall.
The VPN service, which is called by RSA only with the codename “Terracotta”, consists of more than 1,500 nodes worldwide.
A total of 31 hacked Windows servers were discovered. All were found to be hacked servers linked to the Internet, and the Windows servers did not use any hardware firewalls.
