Hard disks and magnetic tape have a limited lifespan, but glass storage developed by Microsoft could last millennia

Some cultures used stone, others used parchment. Some even, for a time, used floppy disks. Now scientists have come up with a new way to keep archived data safe that, they say, could endure for millennia: laser-writing in glass.

From personal photos that are kept for a lifetime to business documents, medical information, data for scientific research, national records and heritage data, there is no shortage of information that needs to be preserved for very long periods of time.

Would you trade your data privacy and security for housing? Thanks to the rise in real estate technologies, renters often have no choice but to hand over huge amounts of revealing information to digital third parties just to have somewhere to live. All the while we are told: trust us, we take your privacy seriously.

But recent Guardian reporting has revealed that seven popular “rent-tech” platforms have serious security vulnerabilities, leaving millions of documents containing personal information of renters exposed on the open web for years. When they were alerted to the risk, only two of the seven companies responded to say they would put additional security measures in place. Is this what taking renter privacy seriously looks like?

Starmer’s team is wary of spies but such fears are not new – with Theresa May once warned to get dressed under a duvet

When prime ministers travel to China, heightened security arrangements are a given – as is the quiet game of cat and mouse that takes place behind the scenes as each country tests out each other’s tradecraft and capabilities.

Keir Starmer’s team has been issued with burner phones and fresh sim cards, and is using temporary email addresses, to prevent devices being loaded with spyware or UK government servers being hacked into.

Russian state has tolerated parallel probiv market for its convenience but now Ukrainian spies are exploiting it

Russia is scrambling to rein in the country’s sprawling illicit market for leaked personal data, a shadowy ecosystem long exploited by investigative journalists, police and criminal groups.

For more than a decade, Russia’s so-called probiv market – a term derived from the verb “to pierce” or “to punch into a search bar” – has operated as a parallel information economy built on a network of corrupt officials, traffic police, bank employees and low-level security staff willing to sell access to restricted government or corporate databases.

It’s become the playbook for big Australian companies that have customer data stolen in a cyber-attack: call in the lawyers and get a court to block anyone from accessing it.

The outsourcing company Capita has been fined £14m for data protection failings after hackers stole the personal information of 6.6 million people, including staff details and those of its clients’ customers.

‘Brit card’ already facing opposition from privacy campaigners as government looks for ways to tackle illegal immigration

All working adults will need digital ID cards under plans to be announced by Keir Starmer, in a move that will spark a battle with civil liberties campaigners.

The names, pictures and addresses of about 8,000 children have reportedly been stolen from the Kido nursery chain by a gang of cybercriminals.

As Keir Starmer aims to revive ID card system first proposed by Tony Blair, we look at the arguments for and against

It is 21 years since Tony Blair’s government made proposals for an ID card system to tackle illegal working and immigration, and to make it more convenient for the public to access services.

The same issues are on the agenda again as Keir Starmer revives what became one of New Labour’s most controversial policies. He is about to find out if he can defeat the argument that David Cameron’s Conservatives made before scrapping it. They said the ID card approach to personal privacy was “the worst of all worlds – intrusive, ineffective and enormously expensive”.

CSRI finds China and Russia may be coordinating ‘grey zone’ tactics against vulnerable western infrastructure

China and Russia are stepping up sabotage operations targeting undersea cables and the UK is unprepared to meet the mounting threat, according to new analysis.

A report by the China Strategic Risks Institute (CSRI) analysed 12 incidents in which national authorities had investigated alleged undersea cable sabotage between January 2021 and April 2025. Of the 10 cases in which a suspect vessel was identified, eight were directly linked to China or Russia through flag-state registration or company ownership.

Citizen Lab says it found ‘digital fingerprints’ of military-grade spyware that Italy has admitted using against activists

The hacking mystery roiling the Italian prime minister Giorgia Meloni’s rightwing government is deepening after researchers said they had found new evidence that two more journalists were targeted using the same military-grade spyware that Italy has admitted to using against activists.

A parliamentary committee overseeing intelligence confirmed earlier this month that Italy had used mercenary spyware made by Israel-based Paragon Solutions against two Italian activists.
