The hacker made his mark.

A pro-Israel activist hacked The Syrian Times website and posted an Israeli flag on the About Us page, Israel’s Channel 2 reported Sunday. The action was in retaliation to Friday’s hacking of the website of Israeli newspaper Haaretz.

The hacker left behind his own stamp, writing “Hacked by YOU-R-!K@N TO THE Syrian electronic army.”

Friday a group that deems itself the Syrian Electronic Army says it gained access to 80 email accounts and passwords of Haaretz employees.

According to Haaretz, an email made to look like it was from the paper’s publisher, Amos Schocken, was sent out that morning. “Dear, please read the following article,” the message said with a subject line marked “Important.” The link was to an article on the website of the British daily The Guardian, about talks between the United States and the Syrian opposition. “Well done,” the message concluded. After clicking on the link, Haaretz Group employees were directed to a page requesting them to enter their email password, which was then used by the hackers to break into their work email accounts.

According to Haaretz, “A short while after the email was sent, Haaretz’s email server shut down; however, it appears that internal company email correspondence fell into the hands of the hackers.”

That same day the Syrian Electronic Army wrote on the group’s website that, “the next time we will attack government websites in Israel.”
