On Wednesday night, the Saudi hacker released what he said were 200 more Israeli credit card numbers, and called others anti-Israel online activists to step up web attacks.
Responding to the development, 0xOmer said he would release thousands of personal information accounts belonging to Saudis.
"They want force? No problem," he wrote. "We have a further 300,000 working Saudi credit card numbers. We are seriously considering whether we should publicize them," he added.
