Litany Of The Hacked: April 2026 Round-Up

(p.s. programming note: We're doing the April 2026 Litany of the Hacked today to make room for a multi-part special series starting Monday. Come back next week for our three-part series!)

Do April cyber-attack showers bring May cybersecurity flowers? Better hope so!

The litany of the hacked is our listing for each known/reported hack in the previous month. The point of the litany is not shame but awareness-raising that, well, these sorts of things happen.

And so, the litany of the hacked for April 2026.

Our litany this month reflects...I think the word is hubris (or hýbris), to be classical: the über-hacker-program, Mythos, the One AI To Rule Them All, was -- hacked! “We’re investigating a report claiming unauthorised access to Claude Mythos Preview through one of our third-party vendor environments,” said Anthropic.

One implication is that nothing is entirely safe when people start getting involved. Another, to be a little more cheerful, is that the AI arms race to AGI (or especially artificial general super-intelligence) has a long way to go, in part because a lot of people lack GI.

And as a bonus, note that "third-party vendors" are again back in the cyber-attack news.

Back to the litany, which now includes (among others):

Be Prime...Vercel...Brockton Hospital...Sweden's thermal power plant...Booking.Com...Kraken...RCI Hospitality...Winona County (MN)...LAPD...China's National Supercomputing Center (another human-enabled job)...LA Metro...the Uffizi gallery (!)...Hims & Hers...Brokk...TriZetto...

There's a lot of doom and gloom out there on the role of AI. The lessons we see however implicate people as your main threat vector. You know what to do.

Ask us how you can pivot from defending your perimeter to creating a proactive from-within defense.
