Pneumonia is a potentially fatal lung infection that progresses rapidly. Patients with pneumonia symptoms – such as a dry, hacking cough, breathing difficulties and high fever – generally receive a stethoscope examination of the lungs, followed by a chest X-ray to confirm diagnosis. Distinguishing between bacterial and viral pneumonia, however, remains a challenge, as both have similar clinical presentation.

Mathematical modelling and artificial intelligence could help improve the accuracy of disease diagnosis from radiographic images. Deep learning has become increasingly popular for medical image classification, and several studies have explored the use of convolutional neural network (CNN) models to automatically identify pneumonia from chest X-ray images. It’s critical, however, to create efficient models that can analyse large numbers of medical images without false negatives.

Now, K M Abubeker and S Baskar at the Karpagam Academy of Higher Education in India have created a novel machine learning framework for pneumonia classification of chest X-ray images on a graphics processing unit (GPU). They describe their strategy in Machine Learning: Science and Technology.

Since its launch in November 2022, ChatGPT, an artificial intelligence (AI) chatbot, has been causing quite a stir because of the software’s surprisingly human and accurate responses.

The auto-generative system reached a record-breaking 100 million monthly active users only two months after launching. However, while its popularity continues to grow, the current discussion within the cybersecurity industry is whether this type of technology will aid in making the internet safer or play right into the hands of those trying to cause chaos.

Chinese hackers could also attack the networks of companies that provide services to the military or to critical infrastructure operators, holding their systems hostage for ransom payments.

“If you get the right supply chain, it can have a lot of effects against a lot of targets,” said John Hultquist, head of Mandiant Intelligence Analysis at Google Cloud.

China is viewed as one of the most dangerous nations in cyberspace, and its cyber espionage operations are among some of the U.S. government’s top cyber-related investigations. FBI Director Christopher Wray said in 2020 that his agency opens a new investigation into a Chinese counterintelligence effort every 10 hours, and half of the FBI’s counterintelligence investigations are related to China. And the intelligence community’s threats assessments have long warned that China is “almost certainly capable” of launching disruptive and destructive cyberattacks.

Trained across security and networking disciplines and armed with trillions of data signals, Security Copilot dramatically increases the reach, speed and effectiveness of any security team

REDMOND, Wash. — March 28, 2023 — Microsoft Corp. on Tuesday announced it is bringing the next generation of AI to cybersecurity with the launch of Microsoft Security Copilot, giving defenders a much-needed tool to quickly detect and respond to threats and better understand the threat landscape overall. Security Copilot will combine Microsoft’s vast threat intelligence footprint with industry-leading expertise to augment the work of security professionals through an easy-to-use AI assistant.

“Today the odds remain stacked against cybersecurity professionals. Too often, they fight an asymmetric battle against relentless and sophisticated attackers,” said Vasu Jakkal, corporate vice president, Microsoft Security. “With Security Copilot, we are shifting the balance of power into our favor. Security Copilot is the first and only generative AI security product enabling defenders to move at the speed and scale of AI.”

Researchers in the United States have developed a new ultrasonic acoustic attack that can covertly give hackers remote access to many smart devices by turning the device’s microphone and voice assistant against them.

The attack works by using ultrasonic acoustic signals that are inaudible to humans but can be picked up by voice assistants on smart devices, a type of cyberattack commonly referred to as a “SurfingAttack” or “ DolphinAttack.”

With a SurfingAttack, a hacker can modulate voice commands into silent, near-ultrasonic signals, allowing them to issue commands to a smart device, all while a user is blissfully unaware their device has been hijacked.

In this weeks episode of Minutes With we sat down with Mustafa Al-Bassam, a former member of Anonymous and one of the founders of LulzSec.

Mustafa tells us how he got in to hacking and how he ended up getting involved in attacks on The Sun, The Westboro Baptist Church and even the US Government.

The travel and tourism sector has become a prime focus for cyberattacks in recent times, resulting in ransomware incidents arising from data breaches. Against this backdrop, cybersecurity concerns within the industry have escalated with a 4 pc year-on-year (YoY) rise in 2022, reflecting the prevailing sentiment, says GlobalData, a leading data and analytics company.

In its report, Company Filing Analytics Database, GlobalData says that sentiment for airlines, travel services, and lodging rose by 6 pc, 4 pc, and 1 pc, respectively, in 2022 over 2021.

“Companies are consistently working on information and network security projects to set up a reliable technical protection and security management mechanism to ensure customer security and prevent data leakage. A severe data security incident can lead to operational disturbances and cause significant financial damage to the business,” says Misa Singh, Business Fundamentals Analyst at GlobalData.

Online romance fraud is an increasingly common phenomenon, which can affect people of all ages worldwide. This type of fraud occurs when a malicious individual or members of a criminal organization engage with users online pretending to be romantically interested in them, while trying to trick them into sending money or sharing confidential information with them.

Online scams can have a detrimental effect on a victim’s life, causing them to spend all their savings, become indebted, and even be subjected to blackmail or identity theft. A team of researchers at Abertay University in the U.K. recently reviewed existing literature focusing on romance and then summarized some of the most recurring findings in a paper pre-published on arXiv.

“Romance fraud has been growing over the last decade or so and was exacerbated by the COVID-19 pandemic which saw a surge in cybercrime and cyberattacks,” Dr. Lynsay Shepherd, one of the researchers who carried out the study, told Tech Xplore. “Our paper provides a comprehensive overview of romance fraud research, which could serve as a starting point for future research in the field.”

The company is offering rewards ‘for exceptional discoveries’.

OpenAI, the creator of conversational chatbot ChatGPT, has announced a Bug Bounty program where users can report “vulnerabilities, bugs, or security flaws” and be financially rewarded for finding them. The company has announced rewards ranging from $200 to $20,000 depending on the severity of the flaw and teamed up with a popular bug-finding platform to streamline the process.

OpenAI’s ChatGPT has ushered in a race for artificial intelligence (AI) models that provide comprehensive solutions to user queries and can even simulate intriguing imagery with the help of a few text prompts.
