A honeytrap hacker attempted to steal secrets about Britain's stealth fighter jets through Tinder, it has emerged as the Armed Forces are warned over their use of online dating.

An RAF airwoman's dating profile was hijacked by a suspected spy who then got in touch with another RAF serviceman to try and sweet talk details of the F-35 stealth fighter out of him.

Though the source of the hack is unknown, the news comes amid concern about countries such as China and Russia using cyber attacks in a new era of warfare.

Both countries are said to be desperate to acquire the secrets of the F-35 Lightning II fighter. The first planes from the £9bn project arrived in Britain two months ago.

However, the RAF has confirmed that no secrets were released and the man who was targeted is not even connected to the F35 programme.

The woman noticed that her account had been hacked and informed bosses almost immediately.
