AI models may be capable of self-replicating without access to a datacenter \ Anthropic

https://www.anthropic.com/research/self-replicating-ai
Our experiments suggest that small AI models may be months away from being capable enough to self-replicate on commercial IoT devices, like smart ovens and off-brand Android TV boxes. A replicator like this would be challenging to shut down, since there’s no centralized point to shut off - though it may be slow (with a doubling time of days). Unlike non-AI malware, it could also figure out unfamiliar devices on its own. In our evals, a 9B model got inference running on 8 of the 9 hardware types we tested.

Disable Yubikey from typing gibberish on Mac : r/yubikey

https://www.reddit.com/r/yubikey/comments/1k6k5pv/disable_yubikey_from_typing_gibberish_on_mac/
Long-pressing a Yubikey Nano will generate a 44-character random-looking string like "ccccccjlkgjlevtdernkbbnrrvhcvgbljgchbgbdbvgk" as an OTP token because it emulates a keyboard. This is really annoying for Yubikey Nano, which you can leave plugged into your laptop at all times, and gets sporadically triggered by my lap, which my laptop sits on for a long time. I wanted to disable this. Unfortunately, Yubikey Manager is deprecated, so the existing Reddit documentation doesn't help. Instead: - Install Yubikey Manager - Click "Toggle Applications" (see https://imgur.com/a/rhvcPlE) - Uncheck "Yubico OTP" (see https://imgur.com/a/rhvcPlE)

Password Protecting Static Site Content with WASM

https://al9000.com/rust/wasm/static-site-file-decryption/
I use static site generators for my sites. I call out to external APIs to do anything dynamic. The exception is password protection. I'd always thought that needed to be done dynamically on a site's host server. I realized with WASM that's not the case. Files can be encrypted and served statically with a WASM process providing decryption directly on the front end.

Discovering Negative-Days with LLM Workflows | Spaceraccoon's Blog

https://spaceraccoon.dev/discovering-negative-days-llm-workflows/
With this little experiment, I validated a critical threat intelligence workflow - we need to be monitoring for open-source vulnerabilities before (or if ever) a CVE is published. Threat actors are 100% already doing this in some form to quickly weaponise and exploit open-source issues. To emphasise the point: This is already happening.

I got hacked, my server started mining Monero this morning. | Unfinished Side Projects

We should all be using dependency cooldowns

https://blog.yossarian.net/2025/11/21/We-should-all-be-using-dependency-cooldowns
Dependency cooldowns are a free, easy, and incredibly effective way to mitigate the large majority of open source supply chain attacks. More individual projects should apply cooldowns (via tools like Dependabot and Renovate) to their dependencies, and packaging ecosystems should invest in first-class support for cooldowns directly in their package managers.

I don’t want AI agents controlling my laptop – Sophie Alpert

https://sophiebits.com/2025/09/09/ai-agents-security
There’s no good way to say “allow access to everything on my computer, except for my password manager, my bank, my ~/.aws/credentials file, and the API keys I left in my environment variables”. Especially with Simon Willison’s lethal trifecta, you don’t really want to be giving access to these things, even if most of the time, nothing bad happens.

Anyone with 14.7.1. Does it have the equivalent Sequoia non-developer app lockout? | MacRumors Forums

Apple Forces The Signing Of Applications In MacOS Sequoia 15.1 | Hackaday

https://hackaday.com/2024/11/01/apple-forces-the-signing-of-applications-in-macos-sequoia-15-1/
Many MacOS users are probably used by now to the annoyance that comes with unsigned applications, as they require a few extra steps to launch them. This feature is called Gatekeeper and checks for an Apple Developer ID certificate. Starting with MacOS Sequoia 15, the easy bypassing of this feature with e.g. holding Control when clicking the application icon is now no longer an option, with version 15.1 disabling ways to bypass this completely. Not unsurprisingly, this change has caught especially users of open source software like OpenSCAD by surprise, as evidenced by a range of forum posts and GitHub tickets.

Open-Source LLMs - Schneier on Security

https://www.schneier.com/blog/archives/2023/06/open-source-llms.html
We have entered an era of LLM democratization. By showing that smaller models can be highly effective, enabling easy experimentation, diversifying control, and providing incentives that are not profit motivated, open-source initiatives are moving us into a more dynamic and inclusive AI landscape. This doesn’t mean that some of these models won’t be biased, or wrong, or used to generate disinformation or abuse. But it does mean that controlling this technology is going to take an entirely different approach than regulating the large players.

The Facebook Hack Is an Internet-Wide Failure | WIRED

https://www.wired.com/story/facebook-hack-single-sign-on-data-exposed/
On Friday, Facebook announced that hackers had leveraged three separate bugs to collect 50 million users’ so-called access tokens, which are the equivalent of digital keys to a Facebook account. With those tokens, hackers can take full control of users’ Facebook accounts, but because of Single Sign-On, they can also access any other website that those 50 million users log into with Facebook.

The question to me -- as an American and as someone who cares about the integrity of speech -- is how we restore faith in our technology. I don't have the answers to this question right now. Unfortunately this is a long-term problem that will consume the output of researchers and technologists much more talented than I am. I only hope to be involved in the process.

It’s also worth pointing out that we do take certain technical measures to limit the data we collect. We’ve designed Persona so that the identity provider – including the fallback Identity Provider that we run – does not learn your browsing history. We consider that a good security practice, not specifically because of surveillance, but generally because collecting data without a user benefit just creates risk.

The best memorial to the victims of 9/11, in Schneier’s view, would be to forget most of the “lessons” of 9/11. “It’s infuriating,” he said, waving my fraudulent boarding pass to indicate the mass of waiting passengers, the humming X-ray machines, the piles of unloaded computers and cell phones on the conveyor belts, the uniformed T.S.A. officers instructing people to remove their shoes and take loose change from their pockets. “We’re spending billions upon billions of dollars doing this—and it is almost entirely pointless. Not only is it not done right, but even if it was done right it would be the wrong thing to do.”

Cross-domain Ajax with Cross-Origin Resource Sharing | NCZOnline

http://www.nczonline.net/blog/2010/05/25/cross-domain-ajax-with-cross-origin-resource-sharing
"A couple of years ago, web developers were banging their head against the first wall in Ajax: the same-origin policy. While we marveled at the giant step forward enabled by cross-browser support for the XMLHttpRequest object, we quickly bemoaned the fact that there was no way to make a request to a different domain from JavaScript. Everyone setup proxies on their web sites, which was the onset of a new host of open redirect problems, as a way to get around the restriction. Although developers were working around this limitation using server-side proxies as well as other techniques, the community outcry was around allowing native cross-domain Ajax requests. A lot of people are unaware that almost all browsers (Internet Explorer 8+, Firefox 3.5+, Safari 4+, and Chrome) presently support cross-domain Ajax via a protocol called Cross-Origin Resource Sharing."

"No amount of statistical evidence, however, will make any difference to those who give themselves over to almost completely irrational fears. Such people, and there are apparently a lot of them in America right now, are in fact real victims of terrorism. They also make possible the current ascendancy of the politics of cowardice—the cynical exploitation of fear for political gain. ... It's a remarkable fact that a nation founded, fought for, built by, and transformed through the extraordinary courage of figures such as George Washington, Susan B. Anthony and Martin Luther King Jr. now often seems reduced to a pitiful whimpering giant by a handful of mostly incompetent criminals, whose main weapons consist of scary-sounding Web sites and shoe- and underwear-concealed bombs that fail to detonate."

http://adblockplus.org/blog/displaying-web-content-in-an-extension-without-security-issues
"Over the last few years I reported a bunch of security vulnerabilities in various extensions and by far the most common issue was: “Extension Foo allows execution of remote code in privileged context”. Typically, an RSS reader extension would take the content of the RSS feed (HTML code), format it nicely and insert into the extension window. The issue that is overlooked here is that the RSS feed could contain some JavaScript code and it would then execute with the privileges of the extension — meaning for example that it would get full access to the browser (cookies, history etc) and to user’s files. pdp discovered a similar issue in the Firebug extension that uses an HTML-based templating system and forgot to sanitize some input received from the webpage."
