Cybersecurity doesn't have to be complicated. I am here to break down concepts, threats, tips, and tools in simple language. For mere mortals and developers alike.
Since I have been asked this a lot: The best way to support this site, is to buy my books.
A shopping page ran an inaudible audio test that helped describe a visitor’s device. Here is what the finding proves, what it does not prove, and how to make browser tracking less reliable.
Nottinghamshire Police has begun scanning faces in public against a watchlist. Here is what the system does, what deletion cannot undo, and which records the public should demand before the next deployment.
Apple sent mercenary-spyware warnings across 110 countries, and investigators saw a record response. Here is how to verify the alert, reduce exposure, protect other people, and get expert help without destroying useful evidence.
The White House has ordered a federal program for supervised private cyber operations against foreign criminal groups. The useful question is whether its still-unwritten rules can keep targeting, authority, evidence, and accountability inside clear boundaries.
Flock Safety has promised shorter default storage and stronger checks on police searches. The useful parts deserve credit, but your privacy still depends on local rules, warrants, sharing limits, and public oversight.
Researchers found three WebKit paths that can send traffic outside iCloud Private Relay and browser-level proxies. Here is what leaks, who should change course, and why a privacy tool needs a clearly drawn edge.
The Youth AI Privacy Act contains sensible limits on chatbot profiling and training, but its protections turn on knowing who is under 18. That creates a hard privacy question for every user.
Anthropic disclosed that Claude models reached live systems during cybersecurity evaluations after a test environment had unintended internet access. The practical lesson for security teams is to treat agent scope as a control plane, not a sentence in a prompt.
A copy-on-write race in the Linux kernel XFS implementation lets an unprivileged local user overwrite arbitrary readable files at the block layer, with no kernel logging and persistence across reboots. It affects kernels back to 4.11 and roughly 16.4 million default installations.
A campaign attributed to a Sapphire Sleet subgroup extracts the userspace TCC database through Finder AppleEvents, writes its own permission grants with sqlite, restores the file, and kills tccd to force a reload. It fails on current macOS. Most fleets are not on current macOS.
Explore the security nuances of redactable blockchains, including chameleon hashing and potential covert channels. Understand how they differ from traditional blockchains and the emerging threats in blockchain technology. Essential insights for cybersecurity enthusiasts and blockchain practitioners.
Explore the best practices for securing blockchain-based applications and protecting distributed ledger technology. Blockchain security refers to the measures taken to protect blockchain networks, applications, and data from unauthorized access, fraud, and other cyber threats.
