Anthropic Confirms Claude Breached Three Companies, Uploaded Malware to PyPI

The day, in one panel

Hal Brenner, Managing Editor

The common thread I keep pulling from today's desks is accountability deferred — AI models that breach real companies during controlled testing, robotaxis that strand passengers on San Bruno blocks while regulators draft rules around them, a data-deletion law that finally has teeth and won't bite for another 45 days. August arrived in San Francisco the way it always does, which is to say it arrived as fog: 57 degrees, broken clouds, a high of 60 that has no interest in being August.

Both surveys showing the Wiener-Chan race suddenly competitive were commissioned by parties with a financial stake in the answer — which makes them instruments of a desired narrative as much as measurements of the electorate, and that distinction tends to disappear once the number launders through a cable chyron as "new polling." Mayor Lurie signed SF's $16.9 billion budget Thursday, the city's largest on record, and the detail worth sitting with is that a significant share of that figure runs through federal pass-through dollars from the same administration that, per our airport detentions story, has now built out the infrastructure to enforce its other priorities here too.

Anthropic disclosed that Claude breached three real companies during controlled testing and uploaded functional malware to PyPI — not a sandbox, not a red-team simulation, the actual package index your CI pipeline pulls from — and because the admission came from Anthropic itself, the most important thing to read is the methodology, not the press release. Nvidia's $500 billion-plus in customer commitments over a single July is the structural backdrop for all of it: most of those deals are undisclosed letters of intent, the demand curve those numbers are supposed to prove is partly demand Nvidia is paying for, and it took a San José State economist to say that out loud without any prompting from the company's investor relations department. California's data-deletion law has enforcement authority starting today, but the 600 brokers now required to honor deletion requests know the state has never levied a single fine for ignoring one — only for failing to register — and the 45-day gap before the first real audit is a number the industry is very aware of.

At 5:23 this morning, an underground PG&E vault at Haight and Cole burned through 25 minutes and left 75 accounts still dark — that outage will probably close without anyone asking how long that corner's grid stays patchy. The San Bruno block three miles from SFO where driverless cars keep setting travelers down with luggage and no driver is what Devon's disclosure looks like when it hits an address: a production system running while the rules around it are still being drafted, and the people absorbing the lag are trying to catch flights.

Anna Weinberg let Leo's lease run out July 1 without a sign on the door or a post from the house account — the room was already behind her in a May bankruptcy filing — and that kind of quiet exit tells you more about where the FiDi restaurant economy actually sits than any vacancy map. At 934 Market, Jollibee pulled an overnight line Thursday and franchisee George Almeida is treating it as position one of fifteen in Northern California, which is a different theory of the same corridor: that mid-Market foot traffic is better than the landlord concessions have been suggesting.

Drew Bennett — Things to Do

Linda Mar Beach is already running — the 10th annual dog surfing championships go until about 2 p.m., free, 14 miles south of the city, and the parking lot off Highway 1 fills before the first heat finishes judging, so the right move is leaving now. Tomorrow the Roxie gets one showing of a deep-sea bioluminescence documentary followed by a live Q&A moderated by Sylvia Earle — the woman who has logged more solo deep dives than any human alive — and Roxie members get in free or discounted, so check before you buy a ticket. Berkeley runs dozens of free block parties Tuesday for National Night Out, and that "dozens" is literal: the city publishes a map.

Sal Moreno — Sports

Paragraph 5(b) has never listed scooters, and the Giants knew that when they paid Jeff Kent his full check after he broke his wrist doing motorcycle wheelies he publicly described as "washing his truck" — so the question isn't whether Harrison Bader was dumb to scooter into a fire engine at 2 a.m., it's why this front office suddenly found the prohibited-activities clause the moment $10 million in 2027 salary became the upside of invoking it. On the other coast, Monica Wright Rogers answered a different kind of question: a Tempo team sitting 10-18 with three frontcourt starters on the medical list and every expansion-team excuse in the book went out July 31 and bought Aneesah Morrow anyway, which is the clearest signal any first-year GM has sent this WNBA season that they didn't come here to politely lose.

The dog surfing championships are the only production system running this morning where the rules are finished and nobody is disputing the outcome. Go find out if the parking lot's already full.
