Chinese hackers have targeted every Fortune 500 company, according to George Kurtz, the boss of CrowdStrike after the cybersecurity company debuted in New York with an $11bn (£8.7bn) valuation.

"China has been very active in the UK, and certainly in the US, but also outside those regions," said Mr Kurtz. "If you look at any Fortune 500 company, I can tell you, they've certainly been targeted by China."

The Fortune 500 list details the largest companies in the US by revenue, and includes household names such as Ford, Apple and Amazon.

"What we see in the media is really the tip of the iceberg around China, and their activities and abilities to actually gather intelligence and intellectual property," Mr Kurtz said.

The comments come after CrowdStrike, a Sunnyvale, California-based developer of cybersecurity software, joined the Nasdaq earlier this week. Since its debut, its share price has more than doubled. They are currently trading at more than $64 per share, compared to the initial public offering target range of between $28 and $30 a share.

"We're going to continue to be heads-down and not get distracted by the daily stock price," Mr Kurtz said.
