Citibank gags crypto researchers
The gagging order, preventing public disclosure of cryptographic vulnerabilities, was made at the request of CitiBank and Diners' Club against experts due to testify in a 'phantom withdrawal' case to be heard in the South African High Court next month.
South African couple Anil and Vanita Singh say that £50,000 withdrawn through the Diners' Club account through British ATMs in March 2000 was never made by them. Diners Club say that its systems are secure, so the money must have been withdrawn by the Singhs.
