Saudi hacker threatens to expose details of another million credit cards
Days after hacker 0xOmar publishes original list of 400,000 numbers, he releases details of 11,000 more; Credit card companies say only tens of thousands of newly-issued cards were hacked.
The Saudi hacker who earlier this week exposed the details of an estimated 15,000 Israeli credit cards yesterday posted 11,000 additional card numbers and threatened to release the details of one million stolen credit card numbers in all.
In a message posted by "0xOmar" from the Saudi hacking group Group-XP, the hacker claimed he had "hacked much more than you can imagine."
Israeli credit card companies said yesterday they have the new list of hacked numbers and are working to assess the situation. Company employees are briefing affected customers and canceling their cards. Company officials said only a few dozen new cards were in the latest list of numbers, and that they were canceled before any transactions were made.
According to Shai Blitzblau of Maglan Information Defense Technologies, initial checks by company experts indicated that the new file contains only a few hundred new credit card numbers, along with around 4,000 credit card numbers that were exposed in the past year.
In his posting yesterday, "0xOmar" was critical of the cool response of the Israeli media to his earlier claims.
"An Israeli stupid student says it was only 14,000 cards, while only A SIGNLE FILE [sic] we uploaded contains 27000 working credit cards ... Fake Jewish and Zionist lobby media started writing what a stupid student says. This made me a little unhappy. So I've started thinking of sending all Israeli credit cards I own which reaches 1M data. I'll do it soon!" promised "0xOmar."
On Tuesday Group-XP claimed it had obtained personal information about 400,000 Israelis, but checks carried out by the credit card issuers and the Bank of Israel determined that the details of between 14,000 and 15,000 active cards had been exposed. Maglan said yesterday that a total of 31,000 credit card numbers had been exposed in all, some of them belonging to foreign nationals.
