Shadow IT Is Expanding Your Attack Surface. Here’s Proof

bleepingcomputer.com Unknown 2025-10-24 21:15:25

Shadow IT - the systems your security team doesn’t know about - is a persistent challenge. Policies may ban them, but unmanaged assets inevitably slip through. And if defenders don’t uncover them first, there’s always a risk attackers will. With just a few days of effort, Intruder’s security team uncovered multiple real-world examples of Shadow IT exposures: unsecured backups, open Git repositories, unauthenticated admin panels, and more. Every one of them contained highly sensitive data or cr

iOS 26 is giving us a glass-like UI, but Apple’s long-term vision for the iPhone hardware is what former design chief Jony Ive referred to as a “single slab of glass.” A new Apple patent application appears to refer to work on this, describing a “six-sided glass enclosure” … An all-glass iPhone Ive may be long gone from his role at Apple, but the company is believed to be still working toward his vision of a device which would look like a single slab of glass.

Spikes in malicious activity precede new security flaws in 80% of cases

Researchers have found that in roughly 80% of cases, spikes in malicious activity like network reconnaissance, targeted scanning, and brute-forcing attempts targeting edge networking devices are a precursor to the disclosure of new security vulnerabilities (CVEs) within six weeks. This has been discovered by threat monitoring firm GreyNoise, which reports these occurrences are not random, but are rather characterized by repeatable and statistically significant patterns.

Potatoes Evolved From Tomatoes, Study Reveals

That’s it. That’s the news. Genome biologist Sanwen Huang knows a thing or two about potatoes. But his latest potato breakthrough may be his most shocking yet: potatoes are descended from tomatoes. In a Cell paper published today, Huang’s team reports that the modern potato likely emerged about 9 million years ago, when tomato plants married the etuberosum, a potato-like species common to Chile. The origin of the modern potato has puzzled scientists for years, but the new results finally give p

Five companies now control over 90% of the restaurant food delivery market

There is an obvious wave of consolidation in the food delivery market happening right before our eyes. The once-hot food delivery sector has gone cold faster than your DoorDash order. New entrants have disappeared as most of the VC money chases the cool and hip AI startups. Alongside a wave of acquisitions, the world's food delivery market is consolidating in the hands of 5 companies.
