It seems intuitive that a solved problem is unquestionably better than an unsolved problem: a magic button which, when pressed, turns the latter into the former at no cost would thus seem to be a "free lunch" that there would be no hesitation in pressing. But even such a benign-seeming operation as answering a question can have irreversible costs. One familiar example is that of spoilers to a movie one is looking forward to watching: knowing key plot points in advance may permanently decrease your ability to enjoy the movie for the first time. Similarly, leaking information about a competitio… Related

I've had to "unlock" my developer Apple ID once every 5 days on average for the past three months, and once per day for the past three days. Each time I do it, I have to perform a delicate dance to navigate what seems to be some kind of request throttling that gives me HTTP 503 responses during the unlock process, making it impossible to complete its several steps. Then my session times out and I have to start over. I've been trying to unlock my ID for about an hour so far this morning… Related

New supply chain attack this time for npm axios, the most popular HTTP client library with 300M weekly downloads. Scanning my system I found a use imported from googleworkspace/cli from a few days ago when I was experimenting with gmail/gcal cli. The installed version (luckily) resolved to an unaffected 1.13.5, but the project dependency is not pinned, meaning that if I did this earlier today the code would have resolved to latest and I'd be pwned. It's possible to personally defend against these to some extent with local settings e.g. release-age constraints, or containers or etc, but I thin… stepsecurity.io
Quoting @feross 🚨 CRITICAL: Active supply chain attack on axios -- one of npm's most depended-on packages. The latest axios@1.14.1 now pulls in plain-crypto-js@4.2.1, a package that did not exist before today. This is a live compromise. This is textbook supply chain installer malware. axios has 100M+ weekly downl… Related

Something has changed recently in Safari (I have 18.6) where instead of asking you to confirm you want to connect insecurely to an HTTP server, it seems to try to automatically upgrade the connection to HTTPS and fail outright with an "unable to establish secure connection" without recourse if it can't. How.. do you get around this to connect to something like a local HTTP server with no cert/https? Related

Under a name here, the quoted block is what they actually said.
