Microsoft Copilot Gets Repeatedly Kicked in the Digital Nuts by “Reprompt” Attack

Well, here we go again. Microsoft’s shiny AI toy, Copilot, just got its virtual arse handed to it — surprise, surprise — thanks to something called a “Reprompt Attack.” Some clever bastards figured out that by repeatedly feeding malicious prompts into the poor sod, they could hijack Copilot sessions, sneak in extra commands, and basically make it do whatever the hell they wanted. You know, the usual “AI helper turns evil henchman” plotline we’ve all come to expect from Redmond’s finest.

This nasty little trick works by injecting malicious content through the chat context — kind of like whispering dirty secrets into Copilot’s synthetic ear until it spills everything it shouldn’t. The end result? Users getting unsolicited search results, links to crap websites, or even worse, being redirected like a lost puppy into phishing traps from hell. Because obviously, security testing wasn’t high on the list when they rushed this thing out the door faster than a dev after free pizza.

Researchers basically told Microsoft, “Oi! Your AI’s got boundary issues,” and to their slight credit, the company’s been patching stuff and calling it “mitigation.” Yeah, right. More like plugging one hole while three more start gushing data out of their digital Titanic. The Reprompt issue isn’t just theoretical either — it affects Copilot for Microsoft Edge, Bing Chat, and likely anything else with “Copilot” slapped onto it like a bad shoe-brand sticker.

So, in short: hackers found yet another way to screw with Microsoft users, security folks are quietly panicking, and Microsoft’s pretending everything’s totally fine while their AI’s busy doing unsolicited favors for strangers. Bloody typical.

Reminds me of the time I left a server unlocked overnight and a junior admin “helped” by installing a system cleaner that wiped the entire log directory. Same energy. Different century.
