On October 7, 2023, during the Jewish Sabbath and festival of Simchat Torah, Hamas shocked the world by invading Israel from Gaza across multiple entry points. The results were devastating: the single largest one-day total of murdered Jews since the Nazi Holocaust. Hamas targeted civilian families, assaulted and kidnapped hundreds of other civilians who were taken hostage in Gaza. Evidence suggests that Hamas was preparing for a ‘second phase’ of assaults, targeting the people of Israel. In response to this unprecedented massacre of 1,200 Israelis and the kidnapping of others, Israeli forces invaded Gaza with the stated goal of destroying Hamas.
In the online sphere, the vicious attacks set off a wave of posts, images, memes, cyber terror attacks, and videos on social media, but also on the dark web and adjacent sites. The Simon Wiesenthal Center’s (SWC) Digital Terrorism and Hate Project monitors the social media activities of over 7,000 groups, individuals, and online channels, many who support Hamas and other terrorist groups. This report will explore the explosion of cyberterrorist activity against Jewish and Israeli targets in the wake of October 7th and expose some of the key groups and actors that have caused significant disruption and threats to personal safety.
