Week in review: Fake “Windows Update” fuels malware, Salesforce details Gainsight breach

Here’s an overview of some of last week’s most interesting news, articles, interviews and videos: Quantum encryption is pushing satellite hardware to its limits In this Help Net Security interview, Colonel Ludovic Monnerat, Commander Space Command, Swiss Armed Forces, discusses how securing space assets is advancing in response to emerging quantum threats. He explains why satellite systems must move beyond traditional cryptography to remain protected. Monnerat also describes how future communication architectures will need to … More → The post Week in review: Fake “Windows Update” fuels malware, Salesforce details Gainsight breach appeared first on Help Net Security.

Scientists just teleported information using light

Quantum communication is edging closer to reality thanks to a breakthrough in teleporting information between photons from different quantum dots—one of the biggest challenges in building a quantum internet. By creating nearly identical semiconductor-based photon sources and using frequency converters to sync them, researchers successfully transferred quantum states across a fiber link, proving a key step toward long-distance, tamper-proof communication.

Scientists uncover the brain’s hidden learning blocks

Princeton researchers found that the brain excels at learning because it reuses modular “cognitive blocks” across many tasks. Monkeys switching between visual categorization challenges revealed that the prefrontal cortex assembles these blocks like Legos to create new behaviors. This flexibility explains why humans learn quickly while AI models often forget old skills. The insights may help build better AI and new clinical treatments for impaired cognitive adaptability.

Social data puts user passwords at risk in unexpected ways

Many CISOs already assume that social media creates new openings for password guessing, but new research helps show what that risk looks like in practice. The findings reveal how much information can be reconstructed from public profiles and how that data influences the strength of user passwords. The study also examines how LLMs behave when asked to generate or evaluate passwords based on that same personal information. The research team from the University of Cagliari … More → The post Social data puts user passwords at risk in unexpected ways appeared first on Help Net Security.

New observational auditing framework takes aim at machine learning privacy leaks

Machine learning (ML) privacy concerns continue to surface, as audits show that models can reveal parts of the labels (the user’s choice, expressed preference, or the result of an action) used during training. A new research paper explores a different way to measure this risk, and the authors present findings that may change how companies test their models for leaks. Why standard audits have been hard to use Older privacy audits often relied on altering … More → The post New observational auditing framework takes aim at machine learning privacy leaks appeared first on Help Net Security.

Why password management defines PCI DSS success

Most CISOs spend their days dealing with noisy dashboards and vendor pitches that all promise a shortcut to compliance. It can be overwhelming to sort out what matters. When you dig into real incidents involving payment data, a surprising number come down to poor password hygiene. PCI DSS v4.0 raised the bar for authentication, and the responsibility sits with security leaders to turn those requirements into workable daily habits for users and admins. A password manager … More → The post Why password management defines PCI DSS success appeared first on Help Net Security.
