An anonymous reader quotes a report from TechCrunch: Several groups of hacktivists have targeted Israeli websites with floods of malicious traffic following a surprise land, sea and air attack launched against Israel by militant group Hamas on Saturday, which prompted Israel to declare war and retaliate. Israeli newspaper The Jerusalem Post reported Monday that since Saturday morning its website was down “due to a series of cyberattacks initiated against us.” At the time of writing, the paper’s website still appeared down.
Rob Joyce, director of cybersecurity at the National Security Agency, reportedly said at a conference on Monday that there have been denial of service (DDoS) attacks and defacements of websites, without attributing the cyberattacks to particular groups. “But we’re not yet seeing real [nation] state malicious actors,” Joyce reportedly said. […] Joyce’s remarks appear to confirm findings of security researcher Will Thomas, who told TechCrunch that he has seen more than 60 websites taken down with DDoS attacks, and more than five websites that were defaced as of Monday.
It is common for hacktivist groups to launch cyberattacks during armed conflict, similar to what happened in Ukraine. These hackers are often not affiliated with any governments but rather a decentralized group of politically motivated hackers. Their activities can disrupt websites and services, but are far more limited compared to the activities of nation-state hacking groups. Researchers and government agencies like the NSA say they have only seen activity by hacktivists so far in this Hamas-Israel conflict. “The thing that has surprised me about the hacktivism surrounding this conflict is the amount of international groups involved, such as those allegedly from Bangladesh, Pakistan, and Morocco all also targeting Israel in support of Palestine,” said Thomas. “We also seen long-time threat actors returning who have participated in attacks and spread them using the hashtag #OpIsrael for years.”
“I have seen several posts of cybercriminal service operators such as DDoS-for-Hire or Initial Access Brokers offering their services to those wanting to target Israel or Palestine,” he added.
