In a groundbreaking initiative, hackers have decided to bring the ‘learn by doing’ philosophy to U.S. education and healthcare systems by operating under the cozy moniker UAT-10027. Their weapon of choice? The friendly neighborhood tool, Dohdoor, which sounds like something out of a Dr. Seuss book, but is, in fact, a backdoor creeping into systems since 2025.

Meet Dohdoor, the brainchild of hackers who clearly missed a career in home improvement reality shows. This delightful backdoor leverages DNS-over-HTTPS (DoH), because if you’re going to invade privacy, you might as well do it under the guise of secure internet browsing, right? With DoH, those pesky DNS queries—often viewed as the nosy neighbors of internet traffic—are neatly packaged in encrypted bliss, making sure no one else knows how the sausage is made.

The education and healthcare sectors are being thrust into an unplanned curriculum of cybersecurity 101, taught by hackers who believe that real-world experience trumps textbooks. Meanwhile, the healthcare sector can only pray it’s covered for this sort of digital malpractice. Amid all this, Dohdoor stands as a testament to the hacker’s belief in equal opportunity exploitation, ensuring everyone from kindergartners to cardiac surgeons can participate in this shared learning experience.
