This message in the developer tools panel on the Instagram site

Seems like a good idea to put that there. People who know what they're doing won't be bothered by it, but it might save a few people from getting hacked

Yeah, but when a man really wants to see some Instagram models private nudes, he'll ignore all those warnings and then some.

You see it all the time with banking, where somebody has literally had the bank ring them up to ask them if they really know the person they're sending money to, and that they think they're being scammed, and they push on regardless getting angry with the bank, only to be all surprise Pikachu in the papers when they are, unsurprisingly enough, scammed.
- Years ago, when one of those emails with the malicious links was going around (I forget which one), one of our coworkers clicked on it. This one promised pictures of cute kittens. She later said she knew it was fake, but she was hoping she'd still get to see the picture of the kittens...
- They just put that there so I can't see the titties!
- When the cashier at Walmart gets all concerned and asks why you need 50 iTunes gift cards you should stop and think for a second.

I'm admiring the ASCII art - great usage of different characters to smoothe out the outline of the text

Probably generated by a bot
- Somebody had to program that bot! They still sat down and did the hard work of getting it smooth, but for every character
- asciiart is decades old https://en.wikipedia.org/wiki/ASCII_art

Hacker: That's ok, we don't want you to paste stuff in there, we just want you to send us your cookies. It's not like you're eating them anyway…

Hey once your logged in, can I have that unique identifier over there? It's for science. ;>

Yeah, you see this on a few sites.

Think discord has it as well

reddit had a recruitment ad in it, once

Now they'll just try and charge you a fee to mess with it instead
Discord does that

Firefox has a built-in warning against pasting. I think Chromium too. I don't think they warn about account theft, though.

Chromium now requires you to type a string inside the console before it lets you paste anything.
- Firefox as well:
  
  ⚠️ Scam Warning: Take care when pasting things you don’t understand. This could allow attackers to steal your identity or take control of your computer. Please type ‘allow pasting’ below (no need to press enter) to allow pasting.
- Soon browsers will require you to implement fizzbuzz in the console before enabling paste 😅
What would a pasting attack look like and how would it work?
- Now what most people don't know is that websites can insert arbitrary text when you copy stuff of them. A malicious site will abuse that.
  
  It works like that:
  
  You follow a tutorial online or search for a code snippet. You copy some code/said snippet and paste it into a terminal or the browser command line. This copied text is altered by the site to be a one line command to install malware or grab passwords or cookies. All of that is followed by a line break and maybe your real command to lower suspicion.
  
  Some of the terminal or browser shells interpret a line break in the copied text as enter which then executes the command.
  
  To prevent that, get a shell, that doesn't just execute what you paste (fish shell) or a terminal program, that warns you about line breaks (Moba xterm).
  And please check text from unknown sites before pasting it into a program that may execute it right away. (Just paste it into a text editor or look at your clipboard manager like Win+V in windows)
- JavaScript can be used to get your password (if you enter it somewhere after pasting) or a session token, which gives an attacker temporary access to your account, unless a website is designed well enough to suspect that the attacker is not you.
they even straight up disable pasting until you reenable it.

and both browsers warned about identity theft in the error message when i tried it.

With access to front-end javascript comes great responsibility.

discord has it too iirc

Yep, that's the first place where I saw something like that

Lots of sites have this, I'd assume its common security practice for large sites where scammers are aplenty
