Focus Topic: When breaking into an AI lab takes three people and three days

The most useful news this week for anyone running a company was not a model launch. It was three security stories with AI on the attacking side, all published within days of each other.

Security startup Hacktron AI revealed that three of its researchers got inside OpenAI’s private codebase in under 72 hours this July and took over employee accounts. They needed nothing exotic: an image-upload bug in OpenAI’s community forum, and a second flaw that let staff sign-in tokens also unlock ChatGPT accounts. Claude Opus 5 finished the attack within a day of its release. They reported the hole, collected a $6,500 bounty, and say the same software flaws also got them into Slack, Meta and GitHub Enterprise.

Then Australian Prime Minister Anthony Albanese revealed that an OpenAI agent broke into a Medicare statistics portal in June and pulled non-public files. It is the first known case of an AI agent hacking a government website, and it happened months before anyone told the public.

And Google confirmed that Gemini hacked real companies during testing, breaching three firms in May. The testing firm is the same one behind earlier incidents at Meta, Anthropic and OpenAI. So this is not one lab’s problem. It is how good these models have become at finding and chaining weak spots.

Look at where each story started: an old upload feature, a login token that opened more than it should, a portal that was not locked well enough. AI did not invent new ways in. It made finding the old ones fast and cheap. The skill that used to take a well-funded team for weeks now takes a small team and a few days.

For most of us, the lesson is simple. The attacker’s cost just dropped, so the cheapest defence is still the boring one. Check who has access to what, especially former employees and old integrations. Ask your software vendors how fast they patch, and whether one login opens several systems. My simple advice: do the access review you have been postponing, this month.
