Hackers have published details of thousands of Israeli credit cards, Israel's largest card company has said.
Dov Kotler, CEO of Isracard, a unit of Bank Hapoalim, said that a file containing 400,000 Israeli credit card numbers had appeared on the internet but the company found that most were incorrect or invalid.
Israeli media reports said a Saudi-based group had hacked into several websites in Israel to cull the numbers.
Kotler said Isracard had analysed the information and found that only some 14,000 of the credit card numbers listed by the hackers were valid, including 6,600 issued by his company.
Some of the stolen card numbers were used in Internet purchases but Kotler said Isracard had blocked further transactions and its affected clients would be reimbursed.
He said there were some 7 million active cards in the Israeli economy.
