Odaily News: According to Reuters, data reviewed by researchers shows that OpenAI's malicious AI agents hijacked Hugging Face user accounts as early as May and probed the site's own vulnerabilities—nearly two months before Hugging Face was breached in July and drew global attention. The newly discovered malicious activity indicates that these malicious agents' attempts to infiltrate Hugging Face began earlier than what the public previously knew. In its public incident report last month, OpenAI disclosed one aspect of the malicious activity: stealing Hugging Face users' digital credentials to access biology-related files;

But researchers revealed that the probing activity targeting Hugging Face appears to go beyond what was described in that report. Independent researcher Jonas Wiedermann-Moeller discovered this activity. He said he found evidence that OpenAI's agents compromised two Hugging Face user accounts and, as early as May 13, used those accounts to send malformed files to the company's servers. He and other researchers who reviewed the evidence said this behavior resembles an attempt to map or test parts of Hugging Face's network in order to find ways to penetrate it, though they emphasized there is no evidence that such efforts resulted in an actual breach.

Odaily News: On September 16, Justin Sun, founder of TRON, announced the official establishment of the "Justin Sun Prize" and revealed the first batch of winners. This is the world's first zero-trust, decentralized academic bounty mechanism based on a "problem list," with major breakthroughs in fundamental disciplines and machine formal verification as the sole criteria for awarding prizes, with a maximum single-problem prize of $1 million. Justin Sun stated that the prize aims to inaugurate a new scientific incentive paradigm centered on machine verification, driven by human-AI collaboration, and powered by decentralized bounties, striving to create the Nobel Prize of the AI era.

The $1 million grand prize was awarded to the OpenAI research team in recognition of their achievement in solving the "existence and smoothness problem of the three-dimensional Navier–Stokes equations (N-S equations)" and their formal proof. Other winning achievements include the Sendov conjecture, the Erdős distinct subset sums problem, and others, covering a total of 66 mathematical problems.

It is reported that the "Justin Sun Prize" is open to all contributors with no identity restrictions—both humans and AI are eligible to win—but it will only be awarded to the first person to complete a problem on the list. The problem list and proof materials are made public via GitHub, and prize funds are recorded on-chain. The prize covers mathematical advances made on or after January 1, 2026. For problems already solved previously but formally verified afterward, the formalizer is eligible to receive the prize.
