Successfully setup a man-in-the-middle attack to intercept communications.In order to execute the Raccoon Attack, a hacker needs several conditions in place: The attack doesn’t allow a hacker to obtain the private key, so they’d have to perform the attack individually on each connection they want to eavesdrop on.

It allows hackers (in certain situations) to determine a shared session key and use that to decrypt TLS communications between the server and client. The Raccoon attack is a newly discovered vulnerability in TLS 1.2 and earlier versions. What is the Raccoon Attack? How does it work? What should site owners do? (In case you’re wondering: No you don’t have to re-issue any certificates!) The vulnerability only applies in very specific circumstances and is difficult to execute, but software vendors have released patches to block potential attackers from taking advantage of this loophole.

Good news: researchers say it’s “very hard to exploit” and major vendors have already released security patches for it.Ī team of researchers has documented a vulnerability in TLS 1.2 (and earlier versions) that could allow a man-in-the-middle attacker to acquire a shared session key and decrypt SSL/TLS traffic. In Everything Encryption, Industry Lowdown, Monthly Digest Bad news: there’s a vulnerability in TLS 1.2.
