❗ Action Alerts

Worthy Warnings

  • If you’re running VMWare’s ESXi (perhaps on a home NAS or similar), be sure it’s patched, it’s being very actively exploited ATM — nakedsecurity.sophos.com/…
  • OpenSSL, probably the most prolific open source implementation of the TLS protocol that puts the S in HTTPS, has received a significant patch including fixes for critical bugs. Now would be an excellent time to check that your IoT devices are all patched, and if you run your own web server, that it is too — nakedsecurity.sophos.com/…
  • 🧯 Reddit suffered a data breach, but the attackers never gained access to the production system, or any user data — nakedsecurity.sophos.com/…

Notable News

  • Tile have added an anti-theft mode that intentionally makes their tracker undetectable by others, and the only protection they are adding is a need to register with the company with photo ID before it can be enabled — appleinsider.com/… (Editorial by Bart: this seems wrong-headed and dangerous to be — we know tracker stalking is a problem because of how well Apple’s protection work, making a tracker designed not to be discoverable and pretending that having to register so you can be tracked when you’re caught makes no sense to me!)
  • Twitter disable SMS 2FA signup for all but Twitter Blue customers, and existing non-Blue users have 30 days to migrate or their account will lose 2FA protection — blog.twitter.com/…
  • 🇪🇺 The European Union’s Digital Services Act starts to feel real as tech companies start reporting their active user numbers to the EU. The threshold for coming under the act’s purview is 45M active European users, and we now know Apple, Google, Meta & Twitter surpass that — appleinsider.com/…

Palate Cleansers

  • Bart: 🎦 This thoughtful video doesn’t answer the deep questions raised by the current surge in AI brings (nothing can), but it’s given me a much better framework for thinking about it: I tried using AI. It scared me. — youtu.be/…
