Zuckerberg’s Facebook page hacked

Facebook CEO Mark Zuckerberg had his profile hacked by a Palestinian cybersecurity professional who says he only acted after the company ignored his warnings about a vulnerability in their system.

“First, sorry for breaking your privacy and post to your wall,” Khalil Shreateh wrote over the weekend on Zuckerberg’s page. “I no other choice to make after all the reports I sent to Facebook team.”

Shreateh says he found a loophole in Facebook that allowed strangers to post on anyone’s page, whether they’re friends with that person or not — a flaw he said could be exploited by spammers and scammers.

On his website, Shreateh posted his emails to Facebook warning them of the issue, but says the company ignored his messages, leading him to prove his claims by writing on Zuckerberg’s wall.

Facebook says the flaw has since been fixed.

A Facebook security professional named Matt Jones wrote on the Hacker News website over the weekend saying that the company is inundated with correspondences about potential security flaws, and that many of them are written in poor English, so it can be difficult to figure out which warnings are legitimate.

Still, he acknowledged Facebook “should have pushed back asking for more details” from Shreateh.
