The molecular Einstein: One molecule, endless patterns

Is it possible to tile a surface with a single shape in such a way that the pattern never repeats itself? In 2022, a mathematical solution to this ‘Einstein problem’ was discovered for the first time. Researchers have now also found a chemical solution: a molecule that arranges itself into complex, non-repeating patterns on a surface. The resulting aperiodic layer could even exhibit novel physical properties.

The XCSSET info-stealing malware is back, targeting macOS users and devs

A new, improved variant of the XCSSET macOS malware has been spotted “in limited attacks” by Microsoft’s threat researchers. XCSSET macOS malware XCSSET in information-stealing and backdoor-injecting malware targeting Mac users. It’s usually distributed via infected Xcode projects – a collection of files, settings, and configurations that make up an app or framework developed using Xcode, Apple’s official integrated development environment (IDE) for macOS. The threat has been around for years. Past variants even used … More → The post The XCSSET info-stealing malware is back, targeting macOS users and devs appeared first on Help Net Security.

A PostgreSQL zero-day was also exploited in US Treasury hack (CVE-2025-1094)

The suspected Chinese state-sponsored hackers who breached workstations of several US Treasury employees in December 2024 did so by leveraging not one, but two zero-days, according to Rapid7 researchers. It was initially reported that the attackers compromised the Treasury’s BeyondTrust Remote Support SaaS instances via CVE-2024-12356, a previously unknown unauthenticated command injection vulnerability. But, as Rapid7 researchers discovered (and confirmed by testing), “a successful exploit for CVE-2024-12356 had to include exploitation of CVE-2025-1094 in order … More → The post A PostgreSQL zero-day was also exploited in US Treasury hack (CVE-2025-1094) appeared first on Help Net Security.

My Very Personal Guidance and Strategies to Protect Network Edge Devices, (Thu, Feb 6th)

Last week, CISA and other national cyber security organizations published an extensive document outlining “Guidance and Strategies to Protect Network Edge Devices.” [1] The document is good but also very corporate and “bland.” It summarizes good, well-intended advice that will help you secure edge devices. But reading it also made me think, “That's it?” Not that I expected earth-shattering advice eliminating vulnerabilities brought on by accumulating deceased worth of abandoned ware still peddled at often relatively high costs. But I don't know; maybe something more actionable would be helpful.

Researchers shed light on the mechanisms of bacterial flagellar motors

Biological motors, which aid microorganism movement in fluids, are composed of two components — the rotor and stators. Despite much research, the exact molecular mechanism underlying stator function is yet unclear. In a new study, researchers analyzed the flagellar motor in Vibrio alginolyticus using cryo-electron microscopy and described how sodium ion flow through stators underlies stator function. Understanding biological motors better could lead to the development of efficient microscopic machines.
