Just as evil are the pages that don’t let you select text or pictures for copying.

[–] 50MYT@lemmy.world 17 points 11 months ago (1 children)

Or training videos that pause if the window playing the video is not the last thing clicked on.

I ran into this when trying to paste my generated password into the password field on some kind of financial site and I think it is still the most egregious case of security theater I’ve seen yet.

Anyway, you want the “don’t fuck with paste” extension, available on both chrome and firefox.

You don't need this - In about:config, set dom.event.clipboardevents.enabled to false. No Addon needed.

Especially for things like account numbers. No, you're not increasing security, you idiots, you're increasing human error!

It isn't right you need an extension for it, but here we are. Don't F*** With Paste

[–] hessenjunge@discuss.tchncs.de 14 points 11 months ago (1 children)

On Firefox it is some setting under about:config, no need for an extension.

TBF, I kind of get it. If someone is using a public computer you wouldn't want someone to be able to sign into a site they left open because they copied their password.

However, this won't prevent anyone from copying the password into something like notepad and just typing it out. So in the end, it's useless and makes things less user friendly. Which is what I expect these days.

[–] hikaru755@lemmy.world 21 points 11 months ago

I suspect the reasoning for it was more along the lines of "if you're pasting the password, that means you probably saved it in a text file on your desktop or something, and you shouldn't do that so let's stop you from doing it". In reality, it probably didn't work to make anyone store passwords more securely, and only made life unnecessarily harder for people with password managers

  1. User pastes something into site
  2. data still pasted as normal
  3. JScript event clears clipboard and tells user that their clipboard was safely cleared.

Literally just as secure and better behavior. Just use your brain for a few seconds.

Edit: Actually it's MORE secure because disallowing paste leaves the password or whatever in the clipboard without the user necessarily realizing it...

Public computers should just have their pastebin locked.

They shouldn't mess with things on my personal computer.

[–] Anticorp@lemmy.world 11 points 11 months ago

No they shouldn't. They should require a guest account that clears the session on logout. If you fail to log out when you're finished, well, mistakes have consequences. I'm tired of being handcuffed so incompetent people can have their hands held.

[–] nucleative@lemmy.world 17 points 11 months ago (2 children)

My bank uses a TOTP and they not only block paste, they also block all typing. Instead they popup a modal with a 0-9 digit keypand and the location of each number changes every time.

Effing obnoxious.

[–] Shapillon@lemmy.world 6 points 11 months ago* (last edited 11 months ago) (2 children)

That's a security standard preventing keyloggers from guessing your credentials.

[–] cm0002@lemmy.world 11 points 11 months ago

That's ~~a~~ security ~~standard~~ theater pretending to prevent~~ing~~ keyloggers from guessing your credentials.

FTFY

[–] nucleative@lemmy.world 5 points 11 months ago

The TOTP changes every time. For modern totp hashing I'm not sure how many sequential codes a keylogger would need but I'm guessing more than I will ever enter.

Edit, asked ai for an answer to that because I was curious (maybe it's right):

Start AI

That being said, if an attacker were able to collect a large number of TOTP codes, they might be able to launch a brute-force attack to try to guess the private key. However, this would require an enormous amount of computational power and time.

To give you an idea of the scale, let's consider the following:

Assume an attacker collects 1000 TOTP codes, each 6 digits long (a common length for TOTP codes).
Assume the private key is 128 bits long (a common length for cryptographic keys).
Assume the attacker uses a powerful computer that can perform 1 billion computations per second.

Using a brute-force attack, the attacker would need to try approximately 2^128 (3.4 x 10^38) possible private keys to guess the correct one. Even with a powerful computer, this would take an enormous amount of time - on the order of billions of years.

Bank developer played too much RuneScape?

[–] cm0002@lemmy.world 5 points 11 months ago

Lmao I was just about to comment, their bank must have hired a UX designer from Jagex lol

[–] Dagnet@lemmy.world 17 points 11 months ago (8 children)

Came here hoping someone would explain how to use dev tools to remove that block or if there an addon for that, really hate this kind of restriction

[–] taaz@biglemmowski.win 10 points 11 months ago

Firefox often let's you bypass this shit with holding shift + right click or select the text you want to paste and drag and drop it into the field.

[–] maccentric@sh.itjust.works 7 points 11 months ago

In about:config, set dom.event.clipboardevents.enabled to false.

You can sometimes do it anyway by right clicking (or long hold tap) on the text field to get a contextual menu popup

[–] cm0002@lemmy.world 19 points 11 months ago (2 children)

They've started blocking that too on phones, which is what led to this meme lol. Curiously, GBoard has a little button on the top row that shows for freshly copied text when you go into a text field that still works, GBoard must not send the text as a paste when it's done that way. But its only visible once

My impression from when I've encountered this is that it is an attempt to repel bots.

Speculating/knowing about the reason doesn't help when I'm confronted with having to input the password *6mA*P7CCuVyHo8kh%x34!63wm23&uhzSMY3Xy3$*8^%7j$VeH^7

[–] MouldyCat@feddit.uk 13 points 11 months ago

My impression from when I’ve encountered this is that it is an attempt to repel bots.

hmm bots don't use keyboard or mouse copy & paste so I don't see how that makes sense?

my impression is this is just stupid product managers who don't understand why it's a bad idea to force all your users to manually type out their passwords or email addresses just because of the 0.1% of people who would copy and paste one with an error in.

[–] nucleative@lemmy.world 12 points 11 months ago

Bots don't paste. If it a selenium related bot it would inject the value or type out each keypress.

It only causes real users pain

[–] JasonDJ@lemmy.zip 5 points 11 months ago* (last edited 11 months ago)

Weird, that's one character off from my Paramount+ password. I know from typing it on every fucking STB and console that I own and painstakingly quadruple-checking each character when it fails.

You'd think I'd just change to a passphrase but nah. Ain't nobody got time for that. Too busy ranting about user unfriendly problems that shouldn't exist in modern STB apps.

I use "don't fuck with paste", a browser extension.

Let's be real, though, it's not the dev we should be mad at but some suit who thinks they know security demanding it be done that way

[–] Dagwood222@lemm.ee 3 points 11 months ago

Most of the problems in the modern world could be solved if the front line people could to each other directly.

Suits are the bottleneck.

[–] urheber@discuss.tchncs.de 7 points 11 months ago (1 children)

no, thats another layer down. hell + ultra

[–] cm0002@lemmy.world 4 points 11 months ago

Lol yea the comic artist needs to come up with a follow-up 4panel with extra-extra-hell lmao

[–] big_fat_fluffy@leminal.space 4 points 11 months ago (14 children)

On a similar note, by mobile lemmy client won't let me copy test. Can't even select it.

[–] A7thStone@lemmy.world 4 points 11 months ago (1 children)

If you are using Voyager you can hold down on the comment or hit the three dot button and you'll get a menu that gives you a "select text" option. I was annoyed by that until I found it.

[–] AnUnusualRelic@lemmy.world 3 points 11 months ago (1 children)

I eventually found it as well. I'm still a bit annoyed. It's not very convenient.
