North Yorkshire Hospital Adopts AI for Faster Lung Cancer Detection

 

A hospital in North Yorkshire has introduced artificial intelligence (AI) technology to improve the detection of lung cancer and other serious illnesses. Harrogate and District NHS Foundation Trust announced that the AI-powered system would enhance the efficiency and accuracy of chest X-ray analysis, allowing for faster diagnoses and improved patient care. The newly implemented software can analyze chest X-rays in less than 30 seconds, quickly identifying abnormalities and prioritizing urgent cases. Acting as an additional safeguard, the AI supports clinicians by detecting early signs of diseases, increasing the chances of timely intervention. 

The trust stated that the system is capable of recognizing up to 124 potential issues in under a minute, streamlining the diagnostic process and reducing pressure on radiologists. Dr. Daniel Fascia, a consultant radiologist at the trust, emphasized the significance of this technology in addressing hospital backlogs. He noted that AI-assisted reporting would help medical professionals diagnose conditions more quickly and accurately, which is crucial in reducing delays that built up during the COVID-19 pandemic. 

The Harrogate trust has already been using AI to detect trauma-related injuries, such as fractures and dislocations, since July 2023. The latest deployment represents a further step in integrating AI into routine medical diagnostics. Harrogate is the latest of six Yorkshire radiology departments to implement this advanced AI system. The initiative has been supported by NHS England’s AI Diagnostics Fund (AIDF), which has allocated £21 million to aid early lung cancer detection across 64 NHS trusts in England. 

The investment aims to improve imaging networks and expand the use of AI in medical diagnostics nationwide. UK Secretary of State for Science, Innovation, and Technology, Peter Kyle MP, praised the rollout of this AI tool, highlighting its potential to save lives across the country. He emphasized the importance of medical innovation in preventing diseases like cancer from devastating families and underscored the value of collaboration in advancing healthcare technology. As AI continues to revolutionize the medical field, its role in diagnostics is becoming increasingly essential. 

The expansion of AI-driven imaging solutions is expected to transform hospital workflows, enabling faster detection of critical conditions and ensuring patients receive timely and effective treatment. With continued investment and innovation, AI is set to become an integral part of modern healthcare, improving both efficiency and patient outcomes.

NEW Qilin Ransomware Variant Emerges with Improved Evasion Techniques

 



A much more potent version of the Qilin ransomware has been found, according to cybersecurity experts, showing a new and revamped kind that is ready to attack core systems using advanced encryption along with improved stealth techniques.


A Rebranding with a Twist: Qilin's Evolution

The Qilin ransomware operation, which first appeared in July 2022, has now morphed into a more formidable opponent with a new version dubbed "Qilin.B." Known previously as "Agenda," the malware was rebranded and rewritten in Rust, a programming language harder to detect and often used for high-performance systems. The Qilin group is notorious for demanding multi-million dollar ransoms, focusing on high-stakes sectors such as healthcare, where operational disruptions can be particularly severe.

Qilin's latest incarnation has been a powerful tool in mass-attack campaigns. Just last year, a significant cyber attack was launched against Synnovis, a pathology firm providing services to the United Kingdom's NHS, which resulted in the cancellation of thousands of hospital and family doctor appointments. In return for collaborating on campaigns, Qilin partners are promised a large percentage of ransom payments, up to 85% — an arrangement that is structured to encourage high-paying ransomware attacks with the highest payoffs.


Improved Encryption and Obfuscation

This variant, Qilin.B, has the following methods that make their detection a hard nut to crack by the standard systems of security. According to Halcyon, a research firm specialising in cybersecurity, enhanced encryption, such as AES-256-CTR systems that support AESNI, together with RSA-4096 and OAEP padding have been seen in this particular variant. Such standards ensure that decrypting files from this threat is impossible minus the private key, as the case of preventive actions being the only way forward.

Further, the obfuscation technique is available in Qilin.B with which the developers hide the coding language of malware in order to prevent detection via signature-based detection systems. Such evasion mechanisms make the detection and quick response even more difficult by the cyber security teams in case of infections. As reported by the researchers from Halcyon, who had studied malware upgrades, increasing sophistication can be seen in ransomware tactics, specifically Qilin.B was developed to resist reverse engineering as well as delay incident response.


New Tactics to Dodge System Defences

Qilin.B disables important system services such as backup and removes volume shadow copy to prevent rollback of the infected systems. In addition, it disables restarts and self-cleans up by removing the ransomware after a successful attack to minimise digital artefacts. All these features make it more robust for defence against evolving ransomware groups that will continue to change their approach to remain at least a step ahead of security patches.


Growing Need for Cross-Platform Security

As Qilin ransomware is becoming more agile, security experts say the cybersecurity posture of organisations must be more offensive-minded. Qilin.B is rebuilt in Rust and can be executed properly across different environments-from Linux to VMware's ESXi hypervisor. The required security monitoring needs to recognize stealthy methods identified with Qilin.B, including detection of code compiled in Rust because traditional systems would fail to counter it.


Advanced Configurations and Control

Qilin.B. This is another notable configuration option from the attackers so that one can personalise his attack. Thus, this version comes along with new names for some functions, encrypted strings and other complex code, in order to take more time for defence activities and forensic analysis of an incident. According to researchers of the Halcyon company, the best behaviour-based detecting systems should be implemented and it can easily find out what malware does, without the outdated method of searching for signatures by which malware has successfully dodged, in this case.

With the advancements of Qilin.B in terms of encryption and evasion, the security firm Halcyon recommends that organisations supplement their security infrastructure with cross-platform monitoring and backup solutions which are designed to fight against ransomware attacks' newest variations. A more complete system in detecting and responding to threats will still be an asset as ransomware advances through networks well-protected.

Continuous improvement in ransomware-as-a-service (RaaS) points to the intensifying threat that organisations have to grapple with as they secure sensitive data from increasingly sophisticated adversaries. The Qilin operation exemplifies how ransomware groups continue to adapt themselves to avoid defences, so proactive and adaptive security measures are justified in industries.

Cybersecurity Expert Warns NHS Still Vulnerable After Major Ransomware Attack

 

A leading cybersecurity expert has warned that the NHS remains at risk of further cyber-attacks unless it updates its computer systems. This stark warning follows a significant ransomware attack that severely disrupted healthcare services across London. 

Prof Ciaran Martin, the founding CEO of the UK's National Cyber Security Centre (NCSC), told the BBC: "I was horrified, but not completely surprised. Ransomware attacks on healthcare are a major global problem." NHS England announced it was increasing its cybersecurity resilience and had invested $338 million over the past seven years to address the issue. 

However, Prof Martin’s warnings suggest more urgent action is necessary. A recent British Medical Association report highlighted the NHS's ageing IT infrastructure, revealing that doctors waste 13.5 million hours annually due to outdated systems - equivalent to 8,000 full-time medics' time. 

 The cyber-attack on 3 June, described by Prof Martin as one of the most serious in British history, targeted Synnovis, a pathology testing organisation. This severely affected services at Guy's, St Thomas', King's College, and Evelina London Children's Hospitals. 

NHS England declared it a regional incident, resulting in 4,913 outpatient appointments and 1,391 operations being postponed, alongside major data security concerns. The Russian-based hacking group Qilin, believed to be part of a Kremlin-protected cyber army, demanded a $40 million ransom. When the NHS refused to pay, the group published stolen data on the dark web. 

This incident reflects a growing trend of Russian cyber criminals targeting global healthcare systems. Now a professor at the University of Oxford, Prof Martin highlighted three critical issues facing NHS cybersecurity: outdated IT systems, the need to identify vulnerable points, and the importance of basic security practices.

He further said, "In parts of the NHS estate, it's quite clear that some of the IT is out of date." He stressed the importance of identifying "single points of failure" in the system and implementing better backups. 

Additionally, he emphasized that improving basic security measures could significantly hinder attackers, noting: "Those little things make the point of entry quite a lot harder for the thugs to get in." Emphasizing the severity of the recent attack, he said, "It was obvious that this was going to be one of the most serious cyber incidents in British history because of the disruption to healthcare."

Ransomware Attack on Pathology Services Vendor Disrupts NHS Care in London

 

A ransomware attack on a pathology services vendor earlier this week continues to disrupt patient care, including transplants, blood testing, and other services, at multiple NHS hospitals and primary care facilities in London. The vendor, Synnovis, is struggling to recover from the attack, which has affected all its IT systems, leading to significant interruptions in pathology services. The Russian-speaking cybercriminal gang Qilin is believed to be behind the attack. Ciaran Martin, former chief executive of the U.K. National Cyber Security Center, described the incident as "one of the more serious" cyberattacks ever seen in England. 

Speaking to the BBC, Martin indicated that the criminal group was "looking for money" by targeting Synnovis, although the British government maintains a policy against paying ransoms. Synnovis is a partnership between two London-based hospital trusts and SYNLAB. The attack has caused widespread disruption. According to Brett Callow, a threat analyst at security firm Emsisoft, the health sector remains a profitable target for cybercriminals. He noted that attacks on providers and their supply chains will persist unless security is bolstered and financial incentives for such attacks are removed. 

In an update posted Thursday, the NHS reported that organizations across London are working together to manage patient care following the ransomware attack on Synnovis. Affected NHS entities include Guy's and St Thomas' NHS Foundation Trust and King's College Hospital NHS Foundation Trust, both of which remain in critical incident mode. Other impacted entities are Oxleas NHS Foundation Trust, South London and Maudsley NHS Foundation Trust, Lewisham and Greenwich NHS Trust, Bromley Healthcare, and primary care services in South East London. 

The NHS stated that pathology services at the impacted sites are available but operating at reduced capacity, prioritizing urgent cases. Urgent and emergency services remain available, and patients are advised to access these services normally by dialing 999 in emergencies or using NHS 111. The Qilin ransomware group, operating on a ransomware-as-a-service model, primarily targets critical infrastructure sectors. According to researchers at cyber threat intelligence firm Group-IB, affiliate attackers retain between 80% and 85% of extortion payments. Synnovis posted a notice on its website Thursday warning clinicians that all southeast London phlebotomy appointments are on hold to ensure laboratory capacity is reserved for urgent requests. 

Several phlebotomy sites specifically managed by Synnovis in Southwark and Lambeth will be closed from June 10 "until further notice." "We are incredibly sorry for the inconvenience and upset caused to anyone affected." Synnovis declined to provide additional details about the incident, including speculation about Qilin's involvement. The NHS did not immediately respond to requests for comment, including clarification about the types of transplants on hold at the affected facilities. The Synnovis attack is not the first vendor-related incident to disrupt NHS patient services. Last July, a cyberattack against Ortivus, a Swedish software and services vendor, disrupted access to digital health records for at least two NHS ambulance services in the U.K., forcing paramedics to use pen and paper. 

Additionally, a summer 2022 attack on software vendor Advanced, which provides digital services for the NHS 111, resulted in an outage lasting several days. As the healthcare sector continues to face such cybersecurity threats, enhancing security measures and removing financial incentives for attackers are crucial steps toward safeguarding patient care and data integrity.

Cyberattacks CyberCrime Cyberhackers CyberThreat Dark Web Data Breach Data Records Galloway Medical Files NHS

Dark Web Nightmare: Scots NHS Patient Data Breach Exposes Medical Files

 


Following a major data breach at NHS Dumfries and Galloway, patients can access their private medical records online with just a few clicks. It has been reported that an extremely large amount of data has been stolen from the NHS by a group known as INC Ransom. 

To keep this vast amount of personal information confidential, the group demanded a ransom and then uploaded a massive amount of information to the dark web. As a result of the cyber attack on NHS Dumfries and Galloway in March, the data of its victims has now been released onto the dark web. NHS Scotland advised potential victims to remain vigilant about cyber attacks. 

Nevertheless, the media reports claim that a search on the dark web resulted in personal information about six patients, including a disabled child aged 10 and an 81-year-old man who was disabled. In addition to providing patients' names and dates of birth, the documents also include their home addresses and even their personal email addresses, details of the patient's life and medical history, test results, and private disclosures about their condition that were made to physicians. 

In response to the Sunday Mail report, NHS Dumfries and Galloway confirmed to the newspaper that patients have been informed, but they don't know what files the hackers have or how many more individuals have been compromised. Using the dark web, cybercriminals released documents that proved they had hacked the NHS system that were easily accessed by the Sunday Mail. 

There are some of the most personal details about six patients, including an 81-year-old man who was disabled at the age of 10 and a disabled 10-year-old girl. Furthermore, the documents reveal the patient's name and date of birth, in addition to their unique numerical identifiers called CHI numbers. It also gives their home addresses, as well as one person's e-mail address.

Furthermore, they contain intimate details regarding people's lives and medical histories, as well as test results, which are disclosed to doctors privately. According to the Sunday Mail, NHS Dumfries and Galloway has informed six patients that their data has been stolen, but they have no idea how many more have been affected or what files they have on hand.

As deputy leader of Labour, Jackie Baillie asked Health Secretary Neil Gray to explain how the breach occurred and what measures are being taken to prevent it in other health boards As a result of the breach, experts warn that the people whose personal information was compromised may be vulnerable to identity theft and other kinds of fraud. Managing director of the Cybersecurity Research Centre at Abertay University, Professor Lynne Coventry, said, "Health records can contain sensitive health information as well as financial information, making them more valuable than financial records." 

As a result of the data breach, thousands of people may potentially be affected, but authorities are not yet sure how significant it will be. There have been several calls for transparency from the NHS regarding the breach, and Patrick McGuire, partner at Thompsons Solicitors, says the NHS needs to provide support to those who were affected by the breach. 

McGuire also claimed that the NHS could be faced with significant legal claims from individuals whose personal information was exposed. This has got to be one of Scotland's biggest data breaches, possibly even the whole of Scotland. McGuire stated that the amount of information is enormous. The Scottish Conservative party's health spokesman, Dr Sandesh Gulhane, has stated that those whose information has been stolen are likely to seek financial compensation and that defending these claims could prove to be a significant challenge. 

During his interview with the press, Mr Gray revealed that he must take responsibility for the mitigation of the damage and prevent future attacks by explaining to the public what actions are being taken to mitigate these damages. As a result of the scale of the attack, it is difficult for NHS Dumfries and Galloway to determine exactly what data the hackers could access or how many individuals might be impacted. Police Scotland has confirmed that an investigation is ongoing. 

According to the health board, the six patients whose information had already been published online have already been contacted. Moreover, the NHS Scotland regional board has reported that no disruptions were reported to patient-facing services due to the cyber incident and that normal operations continued. 

According to the Scottish government, the cyber attack targeted NHS Dumfries and Galloway and no further incidents have been reported across NHS Scotland as a result of the cyber attack. The company has been around since July 2023, when it appeared on the scene. Numerous organizations, including healthcare institutions, have been indiscriminately targeted by ransomware. 

The group obtains access to the enterprise via phishing emails and exploiting vulnerabilities in software resulting in exploitation of Citrix NetScaler vulnerability CVE-20233519. Using TOR, it communicates with its victims over a TOR-based portal and tracks payments using a unique ID code that is at the heart of every payment.

Data Breach Alert: 3TB of NHS Scotland Data Held Ransom by Cyber Threat

 


A ransomware group targeting a small group of patients has published clinical data related to a small number of those patients on the internet that the Dumfries and Galloway Health Board is aware of. In the meantime, three terabytes of data are also alleged to have been stolen thanks to a security breach that occurred at the National Health Service (NHS) in Scotland, by the INC Ransom extortion gang. 

 As a result of a ransomware attack in a regional branch, NHS Scotland says it has been able to contain the malware, preventing the infection from spreading to other branches and the entire organisation. A group of cybercriminals called INC Ransom claimed responsibility for the attack on NHS Scotland this week, claiming they stole three terabytes (TB) of data and leaked a limited number of sensitive documents as part of the attack. 

Earlier this month, NHS Dumfries and Galloway announced a serious cyberattack that resulted in their hospital being shut down. INC Ransom was offering samples of files that contained medical evaluations, psychological reports, and other sensitive information regarding patients and doctors in accompanying its warning posted on its extortion website. 

Despite the rumours that such a compromise had already been reached, the Scottish government made sure to emphasize that only the NHS Dumfries and Galloway regional health board was affected by this new agreement. Several days later, NHS Dumfries and Galloway officials revealed that during a breach of security two weeks ago, large quantities of personally identifiable information had been accessed, stolen, and exfiltrated, resulting in a large number of people's details being misused. 

As of July 2023, the INC Ransom operation has gained a lot of attention, targeting both government organizations as well as private businesses to extort their data for ransom. Education, healthcare and government institutions, as well as industrial entities like Yamaha Motor Corporation, are among those that suffer losses from this attack. As the attack was likely to have occurred around March 15, reports emerged that a cybersecurity incident was affecting NHS Scotland services. 

There were several sample documents published yesterday by the threat actor in a blog post, including medical assessments, analysis results, and psychological reports on doctors and patients with sensitive details. Throughout its history, INC has shown no restraint in its process of choosing the types of victims it is willing to target, either. 

There have been several incidents of ransomware spreading across the healthcare industry, education, as well as charities. This is something that has happened in its short time on the ransomware scene. The fact remains, though, that very few cybercriminals exercise that level of restraint in the current day and age. Due to the critical nature of healthcare and the fact that it provides several essential services, cybercriminals and ransomware baddies continue to target it. 

There is a chance that there will be a ransom paid if disruptions can be caused, allowing for patients to be cared for with full capability if a ransom is paid. ALPHV/BlackCat was credited by the media with blaming Change Healthcare for a potentially devastating attack spread across a period of weeks across February and March of this year, which knocked out services for weeks on end.

In February, Romania experienced a significant ransomware incident affecting over 100 facilities, highlighting the persistent targeting of healthcare by cybercriminals. This incident is one of numerous examples underscoring the sector's vulnerability to such threats. The United States has responded to this challenge by introducing initiatives like the Advanced Research Projects Agency for Health (ARPA-H) within DARPA. 

This addition to a two-year cash-for-ideas competition aims to discover methods for securing code in critical infrastructure, including healthcare systems. Last summer, the announcement of the Artificial Intelligence Cyber Challenge (AICC) further demonstrated efforts to combat cyber threats. Teams participating in this challenge are tasked with developing autonomous tools to detect code issues in software used by vital organizations like hospitals and water treatment facilities—both prime targets for cybercrime.

ARPA-H has allocated $20 million towards the AIxCC, emphasizing its commitment to safeguarding healthcare from devastating attacks. Such attacks, exemplified by incidents like the one on Change Healthcare, underscore the urgent need for enhanced cybersecurity measures to prevent disruptions that could jeopardize patient care.

Safeguarding the NHS: Protecting Against Potential Cyber Attacks from China

 

Recent concerns have surfaced regarding the vulnerability of the NHS to cyberattacks, particularly from China. Reports indicate that Beijing-backed actors exploited software flaws to access the personal details of millions of Britons. As experts in cybersecurity, it's crucial to address these fears and provide insights into safeguarding against potential cyber threats. 

The prospect of a cyber attack on the NHS by hostile actors underscores the critical importance of robust cybersecurity measures. With the personal details of 40 million Britons potentially compromised, the stakes are high, and proactive steps must be taken to protect sensitive data and preserve public trust in the healthcare system. 

One of the primary concerns raised by these reports is the exploitation of software flaws to gain unauthorized access to personal information. Vulnerabilities in software systems can provide entry points for cybercriminals to launch attacks, compromising the integrity and security of sensitive data stored within NHS databases. 

Furthermore, the involvement of state-backed actors adds a layer of complexity to the threat landscape. Nation-state cyber-attacks are often sophisticated and well-coordinated, making them particularly challenging to defend against. As such, healthcare organizations must remain vigilant and adopt comprehensive security measures to detect and deter potential threats. To defend against potential cyber attacks from China or any other threat actor, the NHS must prioritize cybersecurity at every level. 

This includes implementing robust security protocols, conducting regular risk assessments, and investing in advanced threat detection and response capabilities. Additionally, healthcare professionals and staff members must receive comprehensive training on cybersecurity best practices to recognize and respond to potential threats effectively. By fostering a culture of security awareness and vigilance, the NHS can strengthen its defenses against cyber attacks and mitigate the risk of data breaches. 

Collaboration and information sharing are also essential components of an effective cybersecurity strategy. By partnering with government agencies, cybersecurity experts, and industry stakeholders, the NHS can stay ahead of emerging threats and leverage collective intelligence to bolster its security posture. 

While the prospect of a cyber attack on the NHS is concerning, it's essential to approach these threats with a proactive and informed mindset. By implementing robust cybersecurity measures, fostering a culture of security awareness, and collaborating with relevant stakeholders, the NHS can enhance its resilience against potential cyber threats and safeguard the personal data of millions of Britons.
