A Ukrainian man has been arrested outside a Turkish nightclub for allegedly trying to flog credit card details online, lifted from the victims of the TJX hack, reports the Associated Press.
The man, Maksym Yastremskiy, was arrested weeks ago on suspicion of trafficking data. Recently American law enforcement officials became interested in the case.
The arrest follows the Florida arrests of 10 people suspected of trafficking TJX data.
TJX, the parent company of clothing retailer TK Maxx in the UK and Marshalls in the US, reportedly used WEP encryption to transmit sensitive customer details around one of its Minnesota stores.
WEP encryption is widely recognised as being very easy to crack -- researchers from Darnstadt technical university cracked it in under three seconds in April using a standard laptop.
