An Israeli hacker team published on Tuesday images and personal details of members of the Anonymous hacker collective who participated in the OpIsrael attack against Israeli sites earlier this week, Israel’s Channel 2 reported.

Israeli Elite Force gained access to the computers of 16 Anonymous members and was able to capture screenshots and photos of the anti-Israel hackers with their own webcams. The Israeli team published the information in a Dropbox document via their Facebook page, saying, “Anonymous, next time do not mess with us.”

The file includes the names of the attackers, their countries of origin, and usernames and passwords to various websites they use. Most participants were based in Malaysia and Indonesia, while others were from Portugal, the United Kingdom, Italy, Switzerland, Finland, Algeria and Saudi Arabia.

The lead pro-Israel hacker named on the document, Buddhax, said the ease in which he was able to infiltrate the computers of Anonymous members proves how amateur the anti-Israel attackers are.

“I’m not a great hacker, but I’m at least good enough to expose you,” he wrote. “Next time do not take part in an offensive against Israel. We know who you are, we know where you are. Praise Israel.”

“Everyone knows what ‘OpIsrael’ means, so after the publish of this DOX I’m sure Anonymous ‘hackers’ will think twice next time before they trying attack Israel,” the hacker said.

Lior Pollack, CTO of information security at 2BSecure, told tech site NEXTER that the “exposure carried out by a team of hackers shows that the level of sophistication is very high as shown by the use of advanced tools to reach PC attackers to obtain information, photographs from their cameras through a Trojan horse. It’s not easy, they had to lure the attackers to press all kinds of links to get the Trojan horse in.”

He added that “there is a challenge even in recognizing which tools used can be accessed. Their methods suggests they are much more sophisticated and experienced than those attacking from OpIsrael, who are basically just kids who do basic things.”

NEXTER reported that according to web security company Avnet Cyber and Security Information, “the Israeli hacker’s findings do not only indicate its level of sophistication, but it also indicates their ability to perform basic work better than the anti-Israel hackers.”

Earlier this week AnonymousOpIsrael broke into the Israeli Education Ministry’s website, as well as the websites of the Israel Postal Service and the Central Bureau of Statistics, Israeli daily Yediot Ahronot reported.
