Do You Copy Paste Your Strong Passwords? Clipboardme is here to Hack You

Introduction

Now, it’s easy to copy all the victim browsing data automatically and other personal information using one link. Imagine you are working on your system and doing some online shopping or logging into some website or logging into some server. Your password is little bit strong, so you plan to copy your password and paste it to login into shopping portal or server. If you have done this in your past, do not repeat this in Future. Everything you copy on your system, is copied to a temporary place called Clipboard and this copied content to Clipboard can be stolen by a hacker.

Today we will walk you through a tool called Clipboardme, which is used to copy clipboard data of the Victim. It can be sometimes your credit card, password or other confidential Information. Using this tool we can also take control of victim’s system, if victims enter this shortcut command “windows + x”, “p”, “ctrl + v”  it even injects malicious code. This tool is a built-in python language.
