High 10 cyber safety tales of 2025


Synthetic intelligence (AI) could have dominated wider tech headlines this 12 months – and this held true within the cyber world as effectively – however on the identical time, the safety neighborhood’s issues lengthen far past the chance implications of totally autonomous expertise, as Pc Weekly’s annual prime 10 round-up displays.

5 years after Covid-19, it’s truthful to say that the pandemic remade safety, turning it from a specialist topic into one thing on which everybody has an opinion, and among the largest themes to emerge from the darkish days of lockdown – distant work and provide chain safety – remained speaking factors in 2025, too.

One other leitmotif was the emergence of quantum computing, and particularly the menace it poses to encryption, whereas within the US, radical shifts in coverage underneath a brand new presidential administration had massive ramifications for the trade.

Listed below are Pc Weekly’s prime 10 cyber safety tales of 2025.

We begin with one of many extra curious and long-running tales of the previous 12 months, the scandal surrounding North Korean operatives who obtained distant IT contractor positions with US firms to generate funds for the remoted regime. In the direction of the top of January, the US Division of Justice (DoJ) introduced the indictment of 5 males – two North Koreans, a Mexican and two Americans – within the case.

The prevalence of distant employees, particularly for the reason that Covid-19 pandemic, has made digital job interviews a reality of life, and regardless of much more organisations issuing return to workplace (RTO) orders, many proceed to rent for totally distant positions the place their staff could hardly ever, if ever, bodily meet. Menace actors have been fast to identify this gaping loophole in enterprise safety, and human sources departments have been scrambling to reply.

The expansion in hypothesis across the potential of quantum computing and its affect on the safety world was an enormous subject of dialog this 12 months. In March, the UK’s Nationwide Cyber Safety Centre (NCSC) printed steerage to assist help organisations as they prepare for quantum.

Whereas its prospects seem incredible, within the medium time period the daybreak of quantum computing will render present encryption strategies used to guard delicate information out of date, and the race is now on to develop efficient post-quantum cryptography, or PQC. In line with the NCSC, organisations ought to already be planning for PQC, forward of technical upgrades within the early 2030s. The cyber company desires the UK’s most at-risk organisations to have totally migrated to PQC by 2035 on the newest.

Provide chain safety has change into a fixture within the cyber world over the previous few years, and the subject nonetheless dominated headlines in 2025. In Could, the NHS’s digital chiefs wrote to their suppliers asking them to enroll to a cyber covenant.

The NHS has an extended and troubled historical past of cyber assaults and information breaches – with assaults on companions reminiscent of OneAdvanced and Synnovis disrupting companies and demonstrating the provision chain dangers confronted by healthcare organisations. The well being service requested suppliers to decide to greater requirements round supporting and patching programs, deploy multifactor authentication (MFA), always-on cyber monitoring and significant infrastructure logging, and immutable backups, amongst different issues.

Regardless that it was established throughout his first administration, the US Cybersecurity and Infrastructure Safety Company (CISA) was not resistant to the deep and sweeping cuts enacted by president Donald Trump as his second time period kicked into excessive gear.

With longstanding officers ousted, price range cuts abounding, and threats to the long-running CVE programme that identifies and classifies harmful vulnerabilities, the US cyber institution was rocked to the core in 2025, with knock-on results spreading past America’s borders.

With Microsoft’s longest-lived working system, Home windows 10, lastly falling out of help in October, there have been warnings for customers throughout the UK through the summer time of 2025 – put together to improve now, or put your safety in danger.

The NCSC’s chief expertise officer, Ollie Whitehouse, stated that not upgrading was akin to “incurring a debt at a excessive curiosity with the specter of compelled compensation at a later date” as he implored organisations to improve their PC estates. The company warned that, along with the difficulties customers will see from being out of help, outdated and now unpatched Home windows 10 programs can be prime targets for menace actors – paying homage to the WannaCry incident in 2017, which exploited unpatched variations of Home windows XP.

The UK authorities made progress on its Cyber Safety and Resilience Invoice in 2025, and was lastly capable of lay it earlier than Parliament in November. Forward of this, the same old spherical of consultations, debates and evidence-gathering periods happened, and in July, the Dwelling Workplace introduced {that a} authorized ban on making ransomware funds – masking hospitals and different public well being our bodies, public sector organisations reminiscent of councils and colleges, and operators of essential nationwide infrastructure (CNI), together with datacentres – could be included.

Enacting a ransomware cost ban has broad help nationally – nearly all of responses to a session on the matter supported it – however the topic stays a controversial one, with some sceptical that the ban will make essential UK organisations much less enticing targets for cyber criminals and may very well make it tougher for some to get better if and after they get hit.

The annual Black Hat cyber truthful in Las Vegas brings collectively safety professionals and hackers of every kind, and all the time throws up just a few oddities. This 12 months, Cisco Talos researchers revealed a collection of vulnerabilities – dubbed ReVault – affecting the safety firmware and related utility programming interfaces (APIs) in Dell laptops.

In the course of the course of their analysis, the Talos group found that if a weak system was configured to just accept a biometric fingerprint login, it was doable to tamper with the firmware in order that the fingerprint reader would settle for a non-human bodily enter. In what was certainly a primary for the safety trade, the researchers posted a video on-line wherein they defeated a laptop computer’s biometric safety measures utilizing a spring onion.

Again within the quantum realm, two years after the debut of its Quantum Secure Programme (QSP), Microsoft reported regular progress on incorporating PQC algorithms into among the foundational elements underpinning the safety of its product suite in August.

For a tech firm as ubiquitous as Microsoft, quantum safety is a non-negotiable – getting it fallacious might result in catastrophe – so Redmond desires to maneuver quick and hopes to have its core companies secured earlier than the top of the 2020s. Its general technique rests on three core pillars: updating Microsoft’s personal and third-party companies, provide chain and ecosystem to be quantum-safe; supporting its clients, companions and ecosystems on this aim; and selling world analysis, requirements and companies round quantum safety.

In October, political chaos in Washington DC overflowed into the safety realm when the federal authorities was compelled to close down after non permanent funding measures didn’t get by way of a deeply divided Congress. Sadly, this stalled progress on extending or changing an Obama-era menace information sharing legislation, CISA 2015, which expired on the finish of September.

CISA 2015 set out a framework for data sharing and supplied legal responsibility protections to organisations sharing menace information and cyber intelligence within the public curiosity. Consultants feared its absence wouldn’t solely damage collaboration between the private and non-private sectors, but in addition scale back the US’s capacity to behave as an efficient counterweight to cyber criminals and different menace actors on the world stage. Though CISA 2015 has now been prolonged, the opportunity of one other shutdown in early 2026 might trigger this story to rear its head once more very quickly.

Safety professionals want solely have a look at the month-to-month Patch Tuesday alerts to see how Microsoft’s technological dominance places it on the centre of so many cyber safety tales, and the agency incessantly is available in for flak from those that suppose it’s not doing sufficient to fulfil its safety obligations. Such voices had been in full flood on the finish of 2025 when the Australian, Canadian and American cyber intelligence companies took the step of co-signing an emergency alert and issuing a information to securing Microsoft Change server cases, a key vector in lots of historical past’s most impactful cyber incidents.

The doc laid out a number of proactive safety methods to be utilized to on-premise Change Servers as a part of hybrid environments, and the People described it as a “essential useful resource” for Microsoft customers. However one observer, a former White Home cyber coverage skilled, stated that the very fact a multilateral coalition felt obligated to provide such a useful resource was a “devastating commentary on Microsoft’s safety posture”.
