Thanks to @mikaelthalen.bsky.social for digging into the insecurity & #enshittification of #Google Nest devices. This is why #RightToRepair and #FreeSoftware matters.

This week I guest lectured for the fourth time for Sheree Ip's class at Curtin University #Law 🤓

We walked through the #TornadoCash smart contract, discussing its ability to protect #privacy of transactions.

What's your take? Should #crypto mixers like Tornado Cash and #SamouraiWallet be banned?

There was a *lot* of schadenfreude going around #Twitter X earlier this month about #cloudcomputing outages. I guess what goes around comes around. Where's the #failwhale when you need it... 🐳

A bunch of great people are offering help and vendors + hosts are (mostly) responsive to abuse reports for these #botnets. I'm still being targeted in the most personal way #Aisuru operators can. Most of that I'll talk about soon. Thanks esp. to @briankrebs.infosec.exchange.ap.brid.gy

🙌 My request for the 14emeliaterracewestroxburyma02132 domain associated with the Aisuru #botnet to be terminated has been granted.

This was the most visited domain on the Internet yesterday, far above #Google, #Facebook, #Microsoft, #Apple, and #Amazon.

The additional domain overload [dot] su now too. h/t @briankrebs.infosec.exchange.ap.brid.gy - this is the Aisuru botnet taking different forms. krebsonsecurity.com/2025/10/aisu...

#caturday on the #fediverse might be my highlight of the weekend 📷

Join privacysafe.social and spend time scrolling through hashtag#cat photos, as the Internet should be.

What's #AWS ? Avoid the clownshow🤡 and hang out somewhere that isn't feeling the outage, by design - #decentralized and FREE.

🔆Try privacysafe.social and connect with millions of #fediverse users.

Our @privacysafe.social apps solve the problem of " #Signal down because #AWS down" by *actually* being #federated + allowing you to deploy your own 100% #OpenSource, #FreeSoftware server 😎

See github.com/PrivacySafe and get started.

I recently spoke with @zdnet.bsky.social about the release of #OpenAI’s #Sora2, a tool that can generate lifelike videos from text prompts.

💪 Strong growth in a month for privacysafe.social ! We soft launched 1 yr ago with a handful of accts, publicly announced Dec 2024, but really pushed in the last 30 days on marketing because we're building a #social layer for @privacysafe.social + @cakewallet.com ! Stay tuned 📺

Signups are snowballing, LFG 🤠 privacysafe.social

We're seeing an uptick in signups and, more importantly, user activity at @privacysafe.social privacysafe.social this week 🥂 The sustainable growth model we've been building toward is on the horizon.

We want a #social community with consistent growth of active users. And we're getting there!
