Tails is widely-considered to be the most secure operating system to use on potentially-risky computers. It's noted whistleblower and former NSA contractor Edward Snowden's OS of choice.
Tails is a secure operating system that you can carry around with you on a USB drive to make public computers more secure. Click this link to find out more.
But, it looks like Tails might have a pretty serious vulnerability. Exodus, a company that discovers security risks and sells the information to companies, found the flaw. It notified the world through a Twitter post and said it's going to help Tails fix the problem free of charge.
The company says they've discovered an undisclosed vulnerability that will let attackers deanonymize Tails computers and even execute code remotely, potentially exposing users to malware attacks. Exodus is currently working with Tails to patch the bug, and expects to hand over a full report on the exploit next week.
Exodus won't talk about specifics of the vulnerability because it doesn't want hackers to have access to that information before it can be fixed. Tails hasn't offered specifics either, saying it doesn't know if the problem is with the Tails system or third-party software.
No operating system is foolproof. I will keep my eyes on this story to update you when Exodus and Tails fix the problem.
