Pig butchering / investment scams are next level recently. This is how my Viber and X DMs looks like
Is the bot problem solved on X? Asking for a friend

🚂 I just built the world’s first Matter-secured toy train 😇
You can control the toy train - IoTrain - from any ecosystem that supports Matter, for example, Home Assistant, Apple, Google, Amazon, Samsung, IKEA, Bosch, …
It is open, secure, private (depending on the ecosystem :D ), and cross-platform.

100% legit work 🤣🤣🤣
The initial messages are Twitter/X message requests (not flagged by X), the other is a chat with the contact. I don't know, maybe sus? 😂
(disclaimer: I am not looking for work, I am looking for scammers)

If you are interested in getting started in Hardware Hacking, I highly recommend the Expliot IoT Security learning kit (799 USD).

I just finished controlling LED peripherals via the JTAG debug interface lab, and it was really cool :D

Restarting the network in #Ubuntu is always a brute-force guesswork challenge. I have no idea in which environment which command works.
