A new attack on the standard of encrypting web traffic just got a new famous vulnerability. In fact, the vulnerability is nothing really new—just something from 1998 that reappeared. Cryptographer Daniel Bleichenbacher found the original vulnerability. Therefore the new version is called “Return of Bleichenbacher’s Padding Oracle” — ROBOT.

The vulnerability is that the RSA algorithm stops at different times during its execution if certain error conditions are met. An attacker can use this to craft a specific request. With multiple such requests, he can decrypt traffic sent to and from the website.
