Israeli Hacker Leaks Hundreds of Saudi Credit Cards

Israeli website Ynet published today that a hacker that belongs to the group that hacked yesterday decided not to wait and published the list of credit card numbers.
This was a retaliation on the attack of the “Saudi” hacker 0xOmar on Israeli website and the publishing of thousands of credit card numbers.
The hackers said he’s a soldier in the intelligence corpse.
The hacker was asked what message does he want to convey to 0xOmar, he replied by “you’re not the only one”.
In Saudi-Arabia the responses were relaxed as they claimed that they received no complaints and their systems are secured. In my opinion they’re delusional and they should have learned something from the quick response of Israeli credit card companies who canceled all the published credit cards even without their owners action.
