Last night, I was targeted for a sophisticated phishing attack on my Apple ID. This was a high effort concentrated attempt at me. Other founders are being targeted by the same group/attack, so I’m sharing what happened for visibility. 🧵 Here’s how it went down:

A friend asked me to find out why his connected lightbulb app was asking for his location, so I ducked out to Australia’s favourite hardware store, Bunnings, and grabbed one to check out. The Android grid connect app has 500k+ downloads. Let’s take a quick look! 🧵 (1/n)
I'm ridiculously excited about the #B5AnimatedMovie because it feels the most B5-ish of anything we've done since the original show. Warners was terrific in giving me the freedom to write the story I wanted, and the animation is phenomenal. It's fun, deep, emotional, classic B5.
I got laid off from Zoom, who wants to hire me?! Offensive Application Security Engineer & Meme Expert ✨💅 (DM OPEN RT FOR EXPOSURE PLS)
The original had the best writing and casting of any sci-fi show I've ever watched. My wife wasn't interested but started hanging around more and more when I was watching. Until, one day, she was sitting beside me with tears running down her cheeks after a beloved character died.

I’m glad CISA is providing a companion document w/ the DOJ indictment of the Russian govt operators who targeted ICS. Lots of great info but please don’t follow their mitigation advice for ICS. It’s not practical & in some cases dangerous. A quick thread: us-cert.cisa.gov/ncas/alerts/aa…

I love the Russian people. That is why I have to tell you the truth. Please watch and share.
A historic night at Versailles. After five hours of heated discussions EU leaders said yes to Ukrainian eurointegration. The process started. Now it is up to us and Ukrainians to accomplish it fast. Heroic Ukrainian nation deserves to know that they are welcome in EU.
At today's security council meeting, Lukashenko showed what looks like an actual invasion map. It shows Ukraine military facilities destroyed by missiles from Belarus, attacks directions (everything agrees except Odessa-Transnistria). Also, Ukraine is divided into 4 sectors.
