Omar Choudary finished his master with an excellent research work. However, this work might be threatening the whole banking industry in Europe and in Canada !!!

"Representatives of the UK banking industry have sent a take-down notice (PDF link) to Cambridge University, demanding that they censor a student's webpage as well as his masters thesis (PDF) . The banks' objection is that the information contained in the report might be used to exploit a vulnerability in the Chip and PIN system, used throughout Europe and Canada for credit and debit card payments. The system was revealed to be fundamentally flawed earlier this year, as it allowed criminals to use a stolen card with any PIN. Cambridge University has resisted the demands and has sent a response to the bankers explaining why they will keep the page online."

This is what we can amazing mind.
