Novel attack against virtually all VPN apps neuters their entire purpose
TunnelVision vulnerability has existed since 2002 and may already be known to attackers.
You're viewing a single thread.
Linux and android unaffected, go figure. Anyway..
Not quite what the article says:
When apps run on Linux there’s a setting that minimizes the effects, but even then TunnelVision can be used to exploit a side channel that can be used to de-anonymize destination traffic and perform targeted denial-of-service attacks. Network firewalls can also be configured to deny inbound and outbound traffic to and from the physical interface. This remedy is problematic for two reasons: (1) a VPN user connecting to an untrusted network has no ability to control the firewall and (2) it opens the same side channel present with the Linux mitigation.
It only works if you have split tunnel setup, which I don't think anybody does for commercial privacy VPNs
Do you mean the attack only works against people with a split tunnel setup?
Yes
