Right after that, erase data from the computer, then again download 200+ GBs of webjunk, then repeat the procedure.

Better, destroy hard drive and PC.

You can communicate in a completely invisible application, such as "maps". Or even tables (just like spies), which is shown in this music video in the 13th second.



But I suggest using Jabber via Tor + OTR or Matrix: github.com/OffcierCia/Cry…

Breaking RSA with a Quantum Computer - Good Read!

Thoughts below 👇
On this note 😅 If we put there a set of data associated with once a living person (which is logical because people will work with the final version of the program), then of course they must have human-like rights...

Let’s say that you can take someone’s brain data (let’s call it a memory plus something else)and upload it to the neural network learning DB, will it eventually look like in PsychoPass?

A third variation of the "address poisoning" attack has been spotted!

In short, you receive tokens which price is displayed in your UI. You then try to exchange them, but the transaction fails, and the gas goes to the scammer’s wallet.

Surprisingly, few people know that anyone can effectively defend against sim swapping…

And yes, it works both in the US and worldwide on almost all mobile operators!

Check out my thread below ⬇️
1/5
To freeze your SIM, contact your mobile phone carrier and ask them to never make changes to your phone number or SIM unless you physically show up to a specific store with at least two forms of identification!
2/5
That is a standard that has been tested by telecommunications operators in the US, the UK, Poland, and China. You just need to insist on it or visit the head office, and I’m sure that the support manager on the phone mayn’t know about it!

Dear followers, If I do not respond to you in DMs here or in TG, it does not mean that I am showing off or don’t like you; rather, it is because I am depressed (again) and really unable to do anything…
I'll get back to everyone as soon as possible. I’m sorry for it.
Dear subscribers, thank you so much for your support! 🫡

I don’t know what I would do if I didn't have this great power behind me! ❤️

Again. This hacker wrote in the chat room a week before he hacked the project and asked to send him 1 matic. I sent him the 1 matic to claim an NFT, and he hacked the project 2 weeks later. Scary.
By the way, I found this hacker via telegram, I even know his face, but unfortunately no one took this information from me.
This information is listed on Polygonscan. I'm not the only one affected - there was another one, who also got a DM from the hacker, asked for some dust, and then hacked into someone's multi-sig.
