On top of this, all but one of the 14 VPN services were found to be vulnerable to DNS hijacking and about half provide connectivity through the Point-to-Point Tunneling Protocol (PPTP) with MS-CHAPv2 authentication, which does not stand up well against brute force cracking attacks.
VPN services have risen in popularity for a multitude of reasons—whether for security on a public hotspot, privacy concerns, or simply as a way to work around regional restrictions on content. This study shows that users should be careful, however, as it's very easy to unwittingly purchase VPN services done wrong.
