Doubts cast over FBI 'leaky CAPTCHA' Silk Road rapture - Security bod says affadavit makes no sense
There are a few who were doing a lot of penetration testing of Silk Road who reckon it wasn't leaking ip's in headers like the FBI are saying. While http headers as well as the data in http replies in various configurations can leak that kind of data, there is enough reputable peeps saying it wasn't the case here.
Be it a 0-day exploit or info gained from other security researchers, it's looking like the FBI's explanation as to how they found Silk road is a bit fishy.
