Is it safer to copy paste important information, say credit card numbers rather than typing them?

Question

Especially when making an online transaction,because to the best of my knowledge almost all spyware and adware softwares can log key strokes,so by copy paste (from a saved text or any other file of course) can one avoid compromising valuable information like credit card numbers?

Answer 1

No. There is javascript available, if used on an unscrupulous website, that can read what you have stored in your clipboard when you open their site.


From http://www.auditmypc.com/security-patch.asp:

Clipboard Access: How to prevent websites from scanning your clipboard or breaching your clipboard security. [Applies to Internet Explorer only.]

Tools > Internet Options > Security > Select a security zone > Custom Level > Scripting > Allow paste operations via script - set this to prompt.

Set "Run ActiveX controls and plug-ins" to "Disable" or "Prompt".

Answer 3

Sounds like a good idea. You could keep all the stuff in a notepad file made on a known clean computer.

Answer 4

to do this you would need to have it stored on computer.so if you have a key loger on pc it is most likley there is a trojen sitting there some where.so i say no.best way is to run virus protection to check for any thing before going to internet to buy any thing.i allways run a check first when i want to buy over the net.

Answer 5

The safest way is to type it using Windows built-in On Screen Keyboard (OSK).

Answer 6

I don't see how but I could be wrong. Besides, you'd have to type it somewhere in order to copy and paste.
