The story of web framework Hono, from the creator of Hono2024-10-17 Hono is a fast, lightweight web framework that runs anywhere JavaScript does, built with Web Standards.

RADIUS/UDP vulnerable to improved MD5 collision attack07/09/2024 The MD5 cryptographic hash function was first broken in 2004, when researchers demonstrated the first MD5 collision, namely two different messages X1 and X2 where MD5(X1) = MD5 (X2). Over the years, attacks on MD5 have only continued to improve, getting faster and more effective against real protocols. But despite continuous advancem

This post is also available in 简体中文, 繁體中文, Français, Español, 日本語, Deutsch and 한국어. IntroductionOn June 27, 2024, a small number of users globally may have noticed that 1.1.1.1 was unreachable or degraded.

We see website operators completely block access to these AI crawlers using robots.txt. However, these blocks are reliant on the bot operator respecting robots.txt and adhering to RFC9309 (ensuring variations on user against all match the product token) to honestly identify who they are when they visit an Internet property, but user agents are trivial for bot operators to change. How we find AI bo
