Null-Prefix SSL Certificate For PayPal Released

An anonymous reader writes "Nine weeks after Moxie Marlinspike presented at Defcon 17, null-prefix certificates that exploit the SSL certificate vulnerability are beginning to appear. Yesterday, someone posted a null-prefix certificate for www.paypal.com on the full-disclosure mailing list. In conjunction with sslsniff, this certificate can be used to intercept communication to PayPal from all clients using the Windows Crypto API, for which a patch is still not available. This includes IE, Chrome, and Safari on Windows. What's worse, because of the OCSP attack that Moxie also presented at Defcon, this certificate cannot be revoked." Update: 10/06 23:19 GMT by KD: Now it seems that PayPal has suspended Marlinspike's account.
