The group called SN_BLACKMETA has taken responsibility for the hack on X and Telegram.

 "They are under attack because the archive belongs to the USA, and as we all know, this horrendous and hypocritical government supports the genocide that is being carried out by the terrorist state of 'Israel,'" the group said.

The group elaborated on its reasoning in a now-deleted post on X.

"Everyone calls this organisation 'non-profit', but if its roots are truly in the United States, as we believe, then every 'free' service they offer bleeds millions of lives. Foreign nations are not carrying their values beyond their borders. Many petty children are crying in the comments, and most of those comments are from a group of Zionist bots and fake accounts," the post said.

SN_BLACKMETA seems to have a real beef with the Archive. It also claimed responsibility for a six-day DDoS attack on the Archive in May.

Chris Freeland, Director of Library Services at the Archive, posted about the attacks in May. SN_BLACKMETA launched its Telegram channel on November 23 and has claimed responsibility for several other attacks, including a six-day DDoS run at Arab financial institutions and various attacks on Israeli tech companies in the spring.
