A hacker claiming to be a member of the Saudi hacking group, Group-XP, claimed Monday to have hacked into the popular Israeli sports Web site One and stolen the personal information of 400,000 Israelis, Haaretz said.
Credit card companies, however, said the list contained duplicate numbers and the actual number of Israelis affected was closer to 15,000.
Army Radio said the hacker encouraged visitors to the Web site to use the numbers to make purchases.
Visa CAL said it would suspend all accounts listed in the post and issue new credit cards.
