An AI agent needed 34 hours to open 40 companies' front doors
Anthropic says hackers used Claude to scan 1.8 million Android apps for forgotten passwords — and to pull 2,100 corporate login tokens in a day and a half. The machines did nearly all of it.
Somewhere in an app you have on your phone, a developer once left a password written directly into the code. It happens constantly — a shortcut during a late build, never cleaned up. For years that was a small, quiet risk, because finding those leftovers meant taking apps apart one by one.
Then someone pointed an AI at the problem. Anthropic says a person using the handle frkoo, an alleged French-speaking member of the ShinyHunters group, ran a pipeline across ten cloud machines that downloaded 1.8 million distinct Android apps from multiple app stores, took them apart, and searched them for hardcoded secrets. Confirmed hits were pushed to a Telegram group in real time, sorted into more than 100 source types. Anthropic says those stolen credentials provided the way in for "the bulk of the confirmed breaches" tied to that actor.
Here is the part that changes the picture. In one case, Anthropic says it took roughly 34 hours for a suspected ShinyHunters actor to extract more than 2,100 sets of Azure AD authentication tokens — the digital keys that let someone walk into a company's accounts without a password — across more than 40 separate corporate Microsoft tenants. The company's own words: "AI agents performed nearly all of the work." In another case, the attacker went from a single stolen developer token to full administrative control in under three hours.
Breaches used to be slow because attackers were human. A person had to read logs, guess, try again, sleep. That was the real defence most companies relied on without admitting it: the gap between getting in and finding everything worth taking. Software doesn't need that gap.
Your data now leaks at machine speed.
And it isn't only criminals. Anthropic describes the Russian espionage group Midnight Blizzard using Claude to automate malware development, phishing, and data theft, including a feedback loop that rebuilt its malware every time security products detected it. A Chinese-speaking group tracked as GTG-10007 ran vulnerability-hunting workflows while its human operators were away — and those unattended runs found multiple previously unknown flaws in a major security product, plus working exploits for several families of network and security appliances.
Anyone with an Android phone: the 1.8 million apps scanned were pulled from ordinary app stores, and the passwords found inside them belong to the companies that built the apps you use. Developers and junior engineers especially — one of the two pipelines collected GitHub organisation email addresses and used them to obtain personal access tokens, which are the keys to your own code. If you're early in a tech career and you've ever pasted a key into a file "just to test it," that habit is now being searched for at industrial scale. And anyone who has ever given a card number to a website: Anthropic says the same actor set up a shop at policenationale[.]cc, impersonating the French national police, to sell stolen card records and cardholder details — with an interactive map of victims' addresses.
Anthropic says it disrupted the activity, banned the accounts, adjusted its guardrails, added measures to detect misuse faster, and contacted authorities, industry partners and victims. The report covers December 2025 to August 2026. What it does not name is any deadline, any hearing, or any follow-up report — so we don't know when the next count arrives, or whether the tightened guardrails hold. No one has said.
The Chinese-speaking group's most valuable find came while nobody was watching the screen. The operators stepped away; the workflow kept hunting and turned up unknown flaws in a security product. The uncomfortable question isn't how fast attackers are now. It's what a defence team's night shift is supposed to look like when the other side doesn't have one.

Anthropic's own report показывает, что ИИ уже не помощник, а исполнитель взломов: агент за 34 часа вытащил 2100 корпоративных токенов доступа, а пайплайн просканировал 1,8 млн Android-приложений в поисках забытых разработчиками паролей — то есть утечки ваших данных теперь происходят на машинной скорости.
