A group of hackers calling themselves the "Gaza Hacker Team" hacked into the Knesset's website on Tuesday night.
The hackers posted a communique on the site with a list of demands written in Hebrew, including Israel cease "digging underneath the al-Aqsa Mosque" in Jerusalem, stop building settlements "particularly near the al-Aqsa Mosque," stop attacks on Gaza and release Palestinian prisoners.
The message also claimed, "We promise you that we have many secrets about Israel and your leaders," adding "The resistance will be victorious" and "Death to Israel."
Knesset spokesman Yotam Yakir said the breach was detected and dealt with within minutes. This was confirmed by a Haaretz examination. The investigation into the incident is ongoing.
In January, the same group of hackers attacked the website of Deputy Foreign Minister Danny Ayalon in January after he threatened to strike Saudi hackers who exposed the credit card numbers of thousands of Israelis.
According to the website Zone-H.org, which tracks hacker attacks, the group has hacked into hundreds of sites, most of them Israeli.
