Many of us travel by airplane and many of us have to deal with carrying luggage. That's a pretty serious threat to your #OpSec unless of course your computer or phone has potentially valuable information on it.

Read my thread ⬇️
1/5

And if you don't fly, you probably travel from point A to point B in some other way - by car, train, and so on.

First of all, try checking out slnt.com/products/ally-… or any custom-made Faraday bag.
2/5

Transfer all important information to physical form. Steganography and cryptography work better when used together!

Surprisingly few people know that anyone can effectively defend against sim swapping. It works both in the US and worldwide in almost all mobile operators!

But how? Check out my thread 👇
1/5

To lock down your SIM, contact your mobile phone carrier. Ask them to NEVER make changes to your phone number/SIM unless you physically show up to a specific store with at minimum two forms of identification.
2/5

This (should) prevent hackers from calling up AT&T or T-Mobile or Vodafone, claiming to be you, and asking them to port your phone number to a new phone.

Researchers have detected an unusual transaction of $718M $ on the BSC network, the meaning of this is not clear at the moment, but many are already talking about a possible hack 🤷‍♂️

However, until official statements are made, it is unlikely to be possible to establish this - due to the technical side of the issue!

Source 2:
718M $ including:

1,04М BNB
$389М in venusBNB

🕊 In this difficult time it's hard to think about anything but global problems, but… I do want us to have something to distract ourselves with, so nothing in my blog will change in terms of content in the near future!

Thank you very much for your attention and take care 🕊
I get asked a lot and I'd like to say it again…

My position: I am 100% pacifist, anti-war, pro-humanity, pro-human-rights.

Mixed (moderate) political views. I love all people.
P.S. New articles 🔜
