Israel has said it will respond to cyber-attacks in the same way it responds to violent “terrorist” acts after the credit card details of thousands of its citizens were published online. A hacker named OxOmar claiming to be Saudi said on Thursday he had leaked the private information. Credit card companies say at least 6,000 valid cards have been exposed. Reports say OxOmar may be a 19-year-old living in Mexico.
