Hundreds of Israeli sites were polluted because of a third-party script on leading sites


Over the weekend, hundreds of leading sites in Israel, including leading sites, were polluted by a page with the caption "Jerusalem is the capital of Palestine".
The security failure is due to the use of those sites in a third-party script of the site that was apparently handled by the attackers.
According to an Israeli researcher named Yuval Adam, the attack was mainly aimed at anti-Israel propaganda and contaminated DNS address details (DNS poisoning)
