Hackers use pixel-large SVG trick to hide credit card stealer

A massive campaign impacting nearly 100 online stores using the Magento e-commerce platform hides credit card-stealing code in a pixel-sized Scalable Vector Graphics (SVG) image.

When clicking the checkout button, the victim is shown a convincing overlay that can validate card details and billing data.

The campaign was discovered by eCommerce security company Sansec, whose researchers believe that the attacker likely gained access by exploiting the PolyShell vulnerability disclosed in mid-March.

New macOS stealer campaign uses Script Editor in ClickFix attack

A new campaign delivering the Atomic Stealer malware to macOS users abuses the Script Editor in a variation of the ClickFix attack that tricked users into executing commands in Terminal.

Script Editor is a built-in macOS application for writing and running scripts, primarily AppleScript and JXA, that can execute local scripts and shell commands. It is a trusted application pre-installed on macOS systems.

While this is not the first time it has been abused for malware delivery, the researchers note that, in the context of the ClickFix social engineering technique, it does not require the victim to manually interact with the Terminal and execute commands.

Microsoft rolls out fix for broken Windows Start Menu search

Microsoft has pushed a server-side fix for a known issue that broke the Windows Start Menu search feature on some Windows 11 23H2 devices.

In a Windows release health update (WI1273488) seen by BleepingComputer, Microsoft said these problems have affected only a small number of users since April 6 and are caused by a server-side Bing update aimed at improving search performance.

While the company says these problems are recent, there have been reports of similar issues surfacing online for months, including claims that the Start Menu displays blank search results that are still clickable.

Key protein found to protect cartilage, offering new hope for osteoarthritis treatment

Osteoarthritis, a condition that causes pain and reduced mobility in joints such as the knees and fingers, is one of the most common joint disorders worldwide, particularly among aging populations. The disease is characterized by the gradual breakdown of cartilage, which normally cushions the bones within joints.

Despite its prevalence, current treatments for osteoarthritis mainly focus on alleviating pain rather than addressing the underlying cause of cartilage degeneration. Effective therapies that can halt or reverse cartilage damage remain limited.

A joint research team led by Dr. Chul-Ho Lee and Dr. Yong-Hoon Kim at the Laboratory Animal Resource Center of the Korea Research Institute of Bioscience and Biotechnology (KRIBB), in collaboration with Prof. JinHyun Kim at Chungnam National University Hospital, has identified a key protein, SHP (NR0B2), that plays a critical protective role in cartilage and may offer a new therapeutic strategy for osteoarthritis. The paper is published in the journal Nature Communications.

How young galaxies grew magnetic fields faster than expected

How fast can a galaxy build ordered magnetic fields spanning thousands of light-years? Existing theories say several billion years, but observations of galaxies in our universe imply shorter timescales. In a study published in the Physical Review Letters and highlighted in the Physics magazine, scientists propose an explanation that resolves this contradiction. They say that the collapse of plasma clouds during the formation of galaxies could significantly accelerate the growth of these magnetic fields.

Almost all visible matter in our universe is in the form of plasma, which can be stirred by forces related to gravity, temperature gradients and rotation. If these lead to turbulent flow, the dynamo theory predicts that the existing magnetic fields in the plasma are amplified. The dynamo theory is our primary framework for understanding the origin of cosmic magnetic fields.

“However, dynamo theory has its limitations,” says Pallavi, an assistant professor at the International Centre for Theoretical Sciences (ICTS) and an author of the study. “In particular, it struggles to explain observations of young galaxies with robust magnetic fields across thousands of light-years.”

DNA polymerase μ protects macrophages from DNA damage produced during pro-inflammatory activation

Polμ is induced in macrophages by ROS upon pro-inflammatory stimuli and is essential for efficient repair of DNA double-strand breaks. Its deficiency compromises macrophage survival and persistence in inflammatory models of infection and tissue repair, underscoring Polμ’s critical role in counteracting ROS-mediated genotoxic stress and in achieving a correct inflammatory resolution.
