Thousands of Exposed GitHub Repositories, Now Private, Can Still Be Accessed Through Copilot (techcrunch.com) 11
An anonymous reader quotes a report from TechCrunch: Security researchers are warning that data exposed to the internet, even for a moment, can linger in online generative AI chatbots like Microsoft Copilot long after the data is made private. Thousands of once-public GitHub repositories from some of the world's biggest companies are affected, including Microsoft's, according to new findings from Lasso, an Israeli cybersecurity company focused on emerging generative AI threats.
Lasso co-founder Ophir Dror told TechCrunch that the company found content from its own GitHub repository appearing in Copilot because it had been indexed and cached by Microsoft's Bing search engine. Dror said the repository, which had been mistakenly made public for a brief period, had since been set to private, and accessing it on GitHub returned a "page not found" error. "On Copilot, surprisingly enough, we found one of our own private repositories," said Dror. "If I was to browse the web, I wouldn't see this data. But anyone in the world could ask Copilot the right question and get this data."
After it realized that any data on GitHub, even briefly, could be potentially exposed by tools like Copilot, Lasso investigated further. Lasso extracted a list of repositories that were public at any point in 2024 and identified the repositories that had since been deleted or set to private. Using Bing's caching mechanism, the company found more than 20,000 since-private GitHub repositories still had data accessible through Copilot, affecting more than 16,000 organizations. Lasso told TechCrunch ahead of publishing its research that affected organizations include Amazon Web Services, Google, IBM, PayPal, Tencent, and Microsoft. [...] For some affected companies, Copilot could be prompted to return confidential GitHub archives that contain intellectual property, sensitive corporate data, access keys, and tokens, the company said.

That's why I only post bad code to github
Got to slow down the machines somehow

Just add a header on the top of the text that asks copilot not to display those repositories. Not like anyone could jailbreak copilot...

How's that "move fast and break things" shit workin' fer ya now?
Maybe all these fuckers will end up forcing the tech sector to eat itself and shit out the fertilizer for something sane, equitable, and sustainable to take its place.
