Judge Simon Mills told Enos his website gave the impression that the tablets were produced in "some sort of professional laboratory by people in white coats and qualifications and expertise".

"On a geological timescale, this is very rapid erosion."A report from the Geological Survey of Northern Ireland shed some light on the problem.

Dr Kirstin Lemon said: "The advice of the Geological Survey to the National Trust is to see if we can remove as many of those coins as we can."By removing them, it means we're stopping any further physical impact on the site itself. We're also stopping that chemical impact as well."She said she hoped that by removing coins, it would stop others adding more.

A specialist stonemason has started the work and has removed about 10% of them so far."He's done some test sites already so we know we can take these coins out without doing damage to the stones themselves," said Dr Henry.

"We want him to do it - we don't want the general public to do that, we don't want to cause any further damage."

Signs will also be put up and visitors are already warned not to insert the coins by tour guides at the Giant's Causeway, like Mark Adams.“I spent a decade learning how to exploit enemy communications,” he says of his background.

Now he co-ordinates the five-strong team.The attack is about gaining access. The objective might be to stop a process from working, such as the core of a nuclear power plant.

The first step for Greg and his team is called passive reconnaissance.Using an anonymous device, perhaps a smartphone only identifiable by its sim card, the team build a picture of the target.
