Covering 150 miles (241km) on foot and by ski while pulling a sledge across Baffin Island, Camilla Hempleman-Adams battled temperatures as low as minus 40C and winds of 75kmph.

This also works the other way - calling people who work on the help desk and pretending to be an employee locked out of their account.Cyber security experts now recommend further layers of security to deal with these sorts of attacks.

"Having code words that get used when an employee phones up to change their credentials, such as "BluePenguin", is one thing being discussed in the cyber community as a way to check that the member of staff is genuine," said Lisa Forte from cyber security firm Red Goat."Ultimately it comes back to the same issue with login credentials as always – we need multiple ways to do it to ensure it isn't easy to bypass."The NCSC advice is the strongest hint yet the hackers are using tactics most commonly associated with a collective of English-speaking cyber criminals nicknamed Scattered Spider.

The name derives from "spider" being the label given to financially motivated cyber criminals, while "scattered" is because they are not a cohesive, organised gang.In the past two years these disparate hackers, in their teens or early twenties, have coordinated and planned attacks on Discord and Telegram to breach dozens of companies and steal or scramble data to extort their victims.

The NCSC does not specifically name the group as being responsible for the current wave of attacks, but acknowledges Scattered Spider are known for these types of hacks.

In other NCSC advice, cyber defenders are being urged to watch out for "Risky Logins".It is hoped the bridge would give pedestrians and cyclists a route across the river away from main roads.

It would link the south of the city and Fletton Quays area to the new university campus, ARU Peterborough.The council is working to redevelop Fletton Quays, with a buyer found for a disused Victorian railway goods shed, which plans to turn it into a food and drinks hall.

The authority has also agreed to sell the unfinished Hilton Garden Inn, which has been under construction for seven years, in the hopes of clawing back its investment in the project.Construction of the bridge is due to start in the summer and go on until spring or summer next year.
