Reconnect, a Facebook hacking tool

Egor Homakov, a security researcher of penetration testing company “Sakurity”, has discovered a vulnerability that allows malicious hackers take over Facebook accounts on websites that use the ‘Login with Facebook’ feature.


The flaw doesn’t allow hackers access to the Facebook’s password, but it does allow them to access your accounts using a Facebook application developed by third-party websites.

Homakov has published a blog post with more information about the CSRF (Cross-Site Request Forgery) vulnerability and a simple tool, called “Reconnect” to exploit the flaw:

RECONNECT is a ready to use tool to hijack accounts on websites with Facebook Login, for example,,, Stumbleupon,,, Vimeo and many others. Feel free to copy and modify its source code. Facebook refused to fix this issue one year ago, unfortunately it’s time to take it to the next level and give blackhats this simple tool.

What is Cross-Site Request Forgery (CSRF)?

Can help us RedTeam Security Consulting:

A cross-site request forgery attack is a type of malicious attack that forces an end-user to execute an unwanted action, without his/her knowledge on behalf of the attacker, within a web application in which the end-user is currently authenticated. In essence, the end-user (victim) is often tricked into clicking on a link, perhaps inside an email sent from the attacker posing as another party, that will perform a function within the website where the end-user is already authenticated. CSRF attacks generally target functions within websites that are considered “high value,” such as areas of websites that allow users to change passwords, transfer money, change an email address or purchase something.
