Cyber-security firm Darktrace has said it intends to list its shares on the London Stock Exchange.

Darktrace did not indicate how much it is seeking to raise, but media reports suggest it could be as much as £3bn.

The move is seen as a sign of confidence in the London market after Deliveroo's flop flotation last month.

The food delivery business saw its shares fall sharply when trading began, casting doubt on efforts to persuade more big tech firms to list in the UK.

Darktrace was set up in 2013 by former members of the UK security services and maths professors.

It was among the first companies in its field to use artificial intelligence (AI) or machine learning to improve cyber-security.

Rather than simply looking for a virus, its systems constantly monitor a company's computer system to look for abnormal patterns or behaviours.

Deliveroo shares tumble on stock market debut
Darktrace chief executive Poppy Gustafsson said a London listing was a "logical choice" for the Cambridge-based firm and that a US listing had not been considered. ทดลองเล่นสล็อต pg

She said Darktrace was a "very different company" from Deliveroo, being "a fundamental technology company".

Darktrace's annual revenue has grown from $79.4m (£57.7m) to $199.1m in the past two years.

However, it did not turn a profit on a pre-tax or operating basis.

Its largest shareholder is Invoke Trust, an investment fund belonging to tech entrepreneur Mike Lynch, who is facing fraud charges in the US related to the sale of his firm Autonomy in 2011 to computer giant Hewlett-Packard.

At least 10,000 UK nationals have been approached by fake profiles linked to hostile states, on the professional social network LinkedIn, over the past five years, according to MI5.

It warned users who had accepted such connection requests might have then been lured into sharing secrets.

"Malicious profiles" are being used on "an industrial scale", the security agency's chief, Ken McCallum, said.

A campaign has been launched to educate government workers about the threat.

The effort - Think Before You Link - warns foreign spies are targeting those with access to sensitive information.
One concern is the victims' colleagues, in turn, become more willing to accept follow-up requests - because it looks as if they share a mutual acquaintance.

MI5 did not specifically name LinkedIn but BBC News has learned the Microsoft-owned service is indeed the platform involved.

The 10,000-plus figure includes staff in virtually every government departments as well as key industries, who might be offered speaking or business and travel opportunities that could lead to attempts to recruit them to provide confidential information.

And it is thought a large number of those approached engaged initially with the profiles that contacted them online.

"No-one is immune to being socially manipulated into wrongdoing through these approaches," the guidance given to government staff says.

LinkedIn has said it welcomes the initiative.

When England footy fans tune in for their side's big Euro 2020 knockout clash with Germany after work on Tuesday, they will be spurred on by the sounds of a Frenchman - whether they realise it or not.

Force Majeure, the cinematic-sounding and typically banging track from Gaspard Augé - aka one half of electronic duo Justice - has been the BBC's official theme song throughout the tournament.

The corporation's choice of tune was music to the ears of the Parisian DJ and producer.

"It was really just the best news for me," Augé tells BBC News, ahead of his country's shock defeat to Switzerland. "Because I made this track with some sort of sporting event - a boxing match or a football match - in [my] head.

"Just this kind of survivor feel to it, something very epic, like when something is about to happen."

He continues: "[I wanted] to create some kind of feeling of invincibility, like when you're walking on the street and listening to a track and you feel really pumped up.

"And I guess it definitely works for the Euros."
The compatriot of Paul Pogba, Kylian Mbappé, Eric Cantona et al admits he doesn't "know much" about le foot, but says he now has "no excuse" not to watch it.

"It's funny because my best friend was never into football since I knew him," he adds, "and now [since the track] he's gone completely crazy about it."

'Set the tone'
The BBC's football creative director Mark Woodward, who helped to select the song, noted how a major sports tournament "deserves a music track to set the tone, and Force Majeure definitely does this".

"This summer, Euro 2020 across the BBC will be consumed by millions and Gaspard's first single as a solo artist works perfectly alongside our TV output," he said.

The TF1 channel in Augé's native France returned the compliment, selecting Higher Power by England's very own Coldplay as its official theme song.

"Maybe it means Brexit is over," jokes Augé. pg slot

"To be fair, to me it just means that the English people have better taste in music."

While the Beeb went for a bit of French electro, soaked in synths, bass and beats, to soundtrack the summer of football, the other UK Euros broadcaster, ITV, did plump for something homegrown - Michael Kiwinuka's You Ain't the Problem.
