Champion ethical hacker warns AI tools like Mythos will make competing harder

An ethical hacker who just won major prizes at a prestigious international competition says her days of competing could be numbered due to the rise of AI tools like Claude Mythos.

Valentina Palmiotti - better known as Chompie - was the most successful individual at the annual Pwn2Own hacking competition in Berlin.

She told BBC News that, for now, AI tools were helping her to win "bug bounties" - money given to hackers who spot vulnerabilities in online systems before they can be exploited by cyber-criminals.

But she said systems like Mythos were so powerful that even champion hackers like her would soon struggle to compete with them.

AI has shaken the cyber-security world, with concerns focussing on Mythos in particular.

Its maker, Anthropic, claims the model has been able to find 1,600 vulnerabilities in hundreds of software programmes.

It says that makes Mythos so potentially dangerous that it can only be released to a select few governments and cyber-security institutions.

Pwn2Own is run by the ZeroDay Initiative and invites human ethical hackers around the world to find vulnerabilities in specific products.

Nearly $1.3m (£970,000) was awarded to hackers this year who collectively discovered 47 brand new hacking methods on various programmes, websites and software.

The flaws have all been reported to grateful companies which are now fixing them before criminals can find the same holes.

On day one of the contest, Chompie successfully demonstrated how to hack one system linked to Nvidia - winning $20,000.

But she then said she had to enter what she called "zombie hacker mode" to prepare for the next day.

"As soon as I won the first prize I ran back to my hotel room to keep working on the other one. I worked from 6pm til 6am and didn't sleep," she said.

It was worth it, and footage from the event shows her looking happy and tired on stage as she successfully hacked into a Linux based system to win $50,000.

Chompie described "zombie hacker mode" as being locked into research and testing for hours fuelled by energy drinks and adrenaline, often wearing a black hoodie.

"It's not healthy," she laughed, but she insisted it was necessary.

This year many champions like Chompie have been using AI to help them while in zombie mode.

She said tools like Claude Code have enabled her to work faster for competitions, and in her day job as a security researcher for IBM X-Force.

Her view was that hackers like her are currently in a "sweet spot" where AI was an aid.

But she predicted the tide would turn soon thanks to new models like Claude Mythos and GPT 5.5 Cyber.

"I competed in Pwn2Own this year because I thought it might be my last chance," she explained.

"That isn't to say that I think that there's going to be no room for security research or ethical hacking, but I think that a lot of the lower-hanging fruit will start to go away."
