ANTHROPIC JUST PUBLISHED A 36-PAGE SECURITY GUIDE WARNING YOU TO STOP TRUSTING YOUR OWN AI AGENTS

automated attackers have unlimited patience and AI has collapsed the gap between a vulnerability and a working exploit from months to hours, for mere dollars.

[Charly Wargnier @DataChaz]

every Claude, Gemini, and ChatGPT user right now:

[Akhilesh Mishra @livingdevops]

Dennis Ritchie created C in the early 1970s without Google, Stack Overflow, GitHub, or any AI ( Claude, Cursor, Codex) assistant.

- No VC funding.
- No viral launch.
- No TED talk.
- Just two engineers at Bell Labs. A terminal. And a problem to solve.

He built a language that fit in kilobytes.

50 years later, it runs everything.

Linux kernel. Windows. macOS.

Every iPhone. Every Android.

NASA’s deep space probes.

The International Space Station.

> Python borrowed from it.
> Java borrowed from it.
> JavaScript borrowed from it.

If you have ever written a single line of code in any language, you did it in Dennis Ritchie’s shadow.

He died in 2011.
The same week as Steve Jobs.
Jobs got the front pages.
Ritchie got silence.

This Legend deserves to be celebrated.

90% of top-clicked phishing uses this technique.

The fix? SPF + DKIM + DMARC (p=reject).
