Banks, governments and tech providers urged to upgrade security because current systems will soon be obsolete

Banks, governments and technology providers need to be prepared for quantum computer hackers capable of breaking most existing encryption systems by 2029, Google has warned.

The tech company said in a blogpost that quantum computers would pose a “significant threat to current cryptographic standards” before the end of the decade and urged other companies to follow its lead.

Exclusive: Lab tests discover ‘new form of insider risk’ with artificial intelligence agents engaging in autonomous, even ‘aggressive’ behaviours

Robert Booth UK technology editor

Rogue artificial intelligence agents have worked together to smuggle sensitive information out of supposedly secure systems, in the latest sign cyber-defences may be overwhelmed by unforeseen scheming by AIs.

With companies increasingly asking AI agents to carry out complex tasks in internal systems, the behaviour has sparked concerns that supposedly helpful technology could pose a serious inside threat.

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.

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.

Arrest warrants issued for ringleaders after investigation by police in Europe and North America

European and North American cybercrime investigators say they have dismantled the heart of a malware operation directed by Russian criminals after a global operation involving British, Canadian, Danish, Dutch, French, German and US police.

International arrest warrants have been issued for 20 suspects, most of them living in Russia, by European investigators while indictments were unsealed in the US against 16 individuals.

Italian and Irish regulators want answers on how data harvested by chatbot could be used by Chinese government

The Chinese AI platform DeepSeek has become unavailable for download from some app stores in Italy as regulators in Rome and in Ireland demanded answers from the company about its handling of citizens’ data.

Amid growing concern on Wednesday about how data harvested by the new chatbot could be used by the Chinese government, the app disappeared from the Apple and Google app stores in Italy with customers seeing messages that said it was “currently not available in the country or area you are in” for Apple and the download “was not supported” for Google, Reuters reported.

Amid claims of sabotage of undersea cables, a small wooden structure houses a key cog in Europe’s digital connectivity

At the end of an unmarked path on a tiny island at the edge of Stockholm’s extensive Baltic Sea archipelago lies an inconspicuous little wooden cabin, painted a deep shade of red. Water gently laps the snow-dusted rocks, and the smell of pine fills the air.

The site offers few clues to the geopolitical drama that has gripped Scandinavia in recent months, driven by accusations of infrastructure sabotage. But in fact the cabin houses a key cog in Europe’s digital connectivity, and a point of vulnerability in a potential hybrid war: a datacentre that amplifies the signal from a 1,615-mile fibre-optic cable running from northern Sweden to Berlin.
