A group hackers, who call themselves "Anonymous Ukrain"Claim that they hold 800 data of millions of stolen credit and debit cards.
To prove their claims, hackers have uploaded part of the data to file-sharing sites and published links to Pastebin that refer to the infringing data.
Oh, yeah archives έχουν μέγεθος 300MB και περιέχουν πληροφορίες για 7 εκατομμύρια cards τύπου MasterCard, Visa, Discover και American Express. Ορισμένοι ερευνητές υποστηρίζουν ότι τα δεδομένα προέρχονται εν μέρει από τις επιθέσεις κατά της αμερικανικής εταιρείας Target – αμερικανοί πολιτικοί κατηγορούν τους χάκερ από την Ουκρανία για διείσδυση στους ηλεκτρονικούς υπολογιστές της αλυσίδας καταστημάτων λιανικής πώλησης και την υποtheft των στοιχείων 40 εκατομμυρίων καρτών πληρωμών.
However the real identity of hackers remains in question. According to massive PR security researchers, the group hacking behind the data leak exploits the name of Anonymous Ukraine, but in reality it is a completely different group.
Anonymous of Ukraine use some standar social networking accounts to promote their actions: @UkraineAnon on Twitter, Anon.Ukraine on Facebook, and Ukrhack on vk.com. These profiles have been used for some time, drawing attention to the turmoil in the Crimea, and the ongoing conflicts between Russia and Ukraine.
However, none of the hackers' accounts have reported the credit card leak, which was announced through the @Op_Ukraine account. The specific profile on Twitter, which has been active for three days, has posted messages that relate exclusively to data leakage.
"We believe that someone is trying to use the name Anonymous Ukrain," said Zimmatore El Reg of Massive PR. "[The leak] was not announced by the official accounts of Anonymous social networks, which usually proudly announce such achievements."
"We have noticed, however, that data leakage is being discussed almost exclusively by the Russian Forum," the investigator noted, pointing out that Russian hackers may be behind "Anonymous Ukrain".
