In April 2017, Anonymous and affiliated groups launched cyberattacks against Israeli websites as part of the annual #OpIsrael campaign.
The first #OpIsrael attacks occurred in 2013, when some divisions of Anonymous launched multiple coordinated cyberattacks against Israeli websites on the eve of Holocaust Remembrance Day on April 8. Every year since, the group and its affiliates carried out similar attacks around the same date, although the date for Holocaust Remembrance Day has changed.
It has been claimed that during the attacks that have taken place so far this year, hundreds of Israeli websites have been taken offline in DDoS attacks. Several Tweets using the hashtag contain Pastebin links where hackers claim to dump the credit card data of several Israeli citizens. One hacktivist group, RedCult, has leaked a list of about 1,000 alleged Facebook users from Israel with their email addresses and passwords.Websites taken offline include those of the Israel Defense Forces, the Israeli Ministry of Justice, the Israeli Ministry of Immigrant Absorbtion, and others.
