Attackers exploit patched macOS Screen Sharing flaw to deploy cryptominer

A recently patched security flaw in Apple macOS is being actively exploited by hackers to bypass authentication, gain root access, and install a cryptominer, the Netherlands’ National Cyber Security Centre (NCSC) warns. The vulnerability, tracked as CVE-2026-65400, , let attackers authenticate to macOS Screen Sharing without valid login credentials. Apple fixed the issue with updates to macOS Sequoia (15.7.9), Sonoma (14.8.9), and Tahoe (26.6.1), and advised its macOS users to upgrade their systems. “An authentication … More → The post Attackers exploit patched macOS Screen Sharing flaw to deploy cryptominer appeared first on Help Net Security.

Police bust cybercrime ring accused of stealing €30 million in four-day spree

German and Brazilian police dismantled an international bank fraud ring blamed for a €30 million cyberattack on a German financial institution, arresting four people in Brazil and pursuing three more suspects in Spain and Bulgaria. Brazilian police named the operation “Klonen.” On August 13, agents executed 21 search-and-seizure warrants across seven cities, including Rio de Janeiro, Goiânia, and Guarulhos. The case traces back to late 2023, when attackers exploited a flaw in the booking process … More → The post Police bust cybercrime ring accused of stealing €30 million in four-day spree appeared first on Help Net Security.

Scientists tracked kids for 8 years — the screen time result was unexpected

An eight-year Finnish study found that children who spent more time on screens tended to show better cognitive processing as teenagers, challenging common assumptions about screen use. Researchers say the key may be balancing physical activity with screen activities that encourage learning, creativity, and active thinking.

Tiny graphene wrinkles create surprisingly powerful electrical effects

Scientists have discovered that tiny, sharply curved wrinkles in graphene can dramatically alter its electrical behavior, creating surprisingly strong charge separation. The finding suggests future electronics could be tuned by reshaping materials at the atomic scale instead of changing what they’re made of.
