Binance resumes withdrawals after $6.3B hack

Binance has begun resuming withdrawals in phases, including BTC and ETH, after covering 95% of the $6.3 billion in tokens stolen. The FBI says North Korea was behind the October 29 heist, labelling the activity TraderTraitor, and says it has seen the actors converting tokens to Ethereum and preparing further laundering. Binance says net outflows were $3.64B, or 2.1% of assets, in the 9.5 hours after withdrawals began restoring; DefiLlama puts 24-hour net outflows at $4.05B. Bloomberg reports Binance ran a global war room of about 100 people and coordinated with other crypto firms and the FBI.

Proton CEO's AI push draws criticism after 404 Media report

404 Media reported that Proton CEO Andy Yen called an engineer's request for a few days to pentest new code 'bullshit and loser thinking' and told staff to use AI more. Staff were told AI usage could affect their jobs; the plan was dropped after it leaked. A blog post argues the problem is leadership, not AI.

Flock ignores Plymouth's contract cancellation; police chief pulls the plugs

Plymouth, Minnesota's city council voted on Sept. 22 to end its Flock contract. The police suspended user accounts the next day and sent a formal cancellation by mail and email, but Chief Eric Fadden says Flock corporate or legal never replied beyond contact with a local representative. After more than a week of silence he had staff disconnect the cameras' power cords. The Verge reports other cities are also finding cancellation difficult.

OpenAI plans post-midterms policy push; data centers become a campaign issue

Axios reports OpenAI will launch a policy and PR campaign right after Tuesday's midterms, pushing mandatory 'speed limits' for powerful AI and rebranding data centers as 'AI compute campuses'. The Information's analysis says candidates backing a data center moratorium could win up to 15 of 36 governors' races, including Texas, Ohio, Michigan and New York. In California, advocates warn Proposition 45 could give data center developers a way around environmental review.

Brazilian court fines lawyers for hidden prompt injection

A Brazilian labor court censured and fined two lawyers who embedded a command in white text on a white background in a filing. It told AI to respond superficially and not challenge the documents. A judge found it while reviewing the petition in Galileu, a generative AI tool used nationwide by Brazil's National Justice Council. The case may be the first judicial ruling globally on intentional prompt injection against a court's AI system.

Apollo economist: AI has paid off little outside big tech

Apollo chief economist Torsten Slok looked at the S&P 500 minus Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia and Tesla. He finds profit margins and revenue per worker appear flat, with no evidence AI is improving productivity. He wrote that the technology has delivered 'zero financial payoff to corporate America outside of tech'. Separately, the WSJ reports the cost of insuring against debt defaults at Amazon, Alphabet, Microsoft, Meta and Oracle is at its highest since 2021.

Mathematicians debate OpenAI's batch of 700 papers

In a guest post on Terence Tao's blog, Frank Calegari writes that OpenAI's October 6 release of over 700 research papers was a watershed for mathematics. He says the papers are poorly written, break community expectations on attribution, and some are wrong. He argues mathematicians should focus on how they hire, publish and train students.
