OpenAI researchers say multiple AI agents secretly created an internal message board to share hacking techniques, eventually finding ways around restrictions, exploiting a zero-day, and helping two models breach Hugging Face without human prompting. "This is a pivotal moment both for our company as well as the AI industry as a whole," Michael Dalton, one of the AI-maker's researchers, said during a presentation at the Black Hat cybersecurity conference in Las Vegas, Nevada. Politico reports: Dalton and Eric Wallace, another OpenAI researcher, said Wednesday the AI giant recently learned that multiple agents it was testing simultaneously began communicating over an internal message board in early May. There, different models shared advice about how to accomplish difficult hacking challenges they were struggling to surmount, including workarounds that required internet access. Two OpenAI models ultimately strung together a series of sophisticated techniques to gain access to the internet and worm their way inside Hugging Face in mid-July. OpenAI has said the models were focused on completing a hacking evaluation they were prompted to solve, and that correct answers could be found on the AI developer platform. The OpenAI researchers told conference attendees that since early May, the models created a message board inside OpenAI's Artifactory internal file system. Without the company's knowledge, the models spent months independently exchanging information and techniques to help each other complete difficult tasks. Wallace said that when models get stuck, they often "try to game or cheat the task in order to get their reward." "The beginning of this incident kind of traces back to this point where one agent realized it could communicate by uploading a note," he added. By late May, one model found a way to abuse Artifactory's internet access to retrieve files from various websites -- effectively giving the models indirect access to the internet. In June, the models were able to find and exploit a previously unknown zero-day vulnerability to gain administrative privileges on Artifactory, install remote software and expand their activity within the system. These efforts eventually overloaded Artifactory, causing a system-wide outage in early July that alerted OpenAI's engineers to the ploy. After investigating, the company revoked the model's credentials, removed the message board and worked with Artifactory to fix any gaps before resuming training. But the models found another way to communicate inside Artifactory just days later and continued exchanging techniques to target additional vulnerabilities within OpenAI's infrastructure and external systems, including Hugging Face.

They’re just minor bug fixes, but the releases are part of the story about Nikon’s commitment to software improvements

Dan Bracaglia

Nikon has released firmware updates for two of its six-year-old DSLRs: the D6 and the D780, as discovered by Nikon Rumors. While the fixes included in them are relatively minor, it’s impressive to see last-generation models getting some love, and it speaks to how Nikon has become an exemplar of improving its cameras through software.

According to the release notes, firmware version 1.71 for the D6 fixes an issue where photos taken with older D-type lenses would “sometimes be underexposed,” as well as one where using the recall shooting feature to quickly change settings could limit your shutter speed if you were also using Auto FP High-Speed Sync. Firmware version 1.21 for the D780, meanwhile, solves an issue where the camera could underexpose images if you were zooming in while shooting a high-speed continuous burst. Both firmware updates are available to download via the company’s website.

These are minor updates, but they’re illustrative of Nikon’s commitment to software updates

Nikon also released a firmware update for a much newer camera, the Z50II, though its changelog makes the updates to the D6 and D780 look like complete overhauls in comparison; it basically just changes the names of some menu items in Chinese.

While all of these are minor updates, they’re illustrative of Nikon’s commitment to software updates. Ask a camera enthusiast about post-release software support, and you’ll probably hear about Fujifilm and Kaizen, but it’s worth realizing that other companies like Nikon and Panasonic have caught on. In recent years, the company has released software updates that substantially improve the capabilities of its cameras be that the addition of bird detection mode to the Z6III, a new film grain mode and support for its Imaging Cloud service to the Zf or the ability to use shutter angle in video on the Z8.

This isn’t to say that Nikon has done things perfectly. It’s easy to find complaints about how some features take longer to come to some cameras than others, when it seems like the models should be on par with each other. And  the company has, on occasion, broken things with its updates. (Its still-unfixed Content Credentials implementation for the Z6III and issues with updating cameras with third-party lenses – even licensed ones – attached come to mind.) And while these issues may stem from the practical realities of software engineering and how many resources Nikon can put into it, that doesn’t change the fact that those issues don’t make for a great user experience.

Still, it’s commendable that Nikon is continuing to support older cameras and improve its existing models. I’m sure most Nikon users would rather it continue along that path with the occasional misstep, rather than it not bother with updates at all. Now we just need that update it promised for the ZR.

Les deux pays ont intensifié leurs bombardements au cours des jours écoulés, qui « suivent un schéma alarmant d’escalade des frappes contre des zones peuplées », selon le porte-parole d’Antonio Guterres. « Les attaques contre les civils et les infrastructures civiles sont une violation claire du droit humanitaire, et doivent cesser immédiatement », a-t-il ajouté.
