An Independent Security Researcher, Sow Ching Shiong, has discovered a serious Password reset vulnerability in Facebook that allowed hackers to change the passwords of facebook accounts.

Normally, User is required to enter his current password before they can set the new one to prevent an unauthorized person from changing the password without the user's knowledge.




However, the Researcher identified that a hacker could change user's password without known the user's current password by accessing the url "https://www.facebook.com/hacked", which automatically redirected to the compromised account recovery page.


In this page,  an attacker was simply prompted to enter the new password and confirm it, without having to know any other information.

Facebook Security Team fixed the vulnerability after being notified by the Security researcher and Sow Ching Shiong has been added to Facebook's white hats list ( https://www.facebook.com/whitehat )

Have you ever been in a situation where you have received a friend request from a very attractive girl and find yourself asking whether it is her or not in her profile pictures? Trust me, you are not alone! I’m sure many of us have been in a similar situation.

There are many reasons why they do that. Sometimes it is because they don’t like to put their own photos online, or they just upload a fake Facebook photo to get more friend requests from opposite sex.



Identify fake profile photos on Facebook

 In this post, I will show you how you can take advantage of reverse image search technology to find for images by uploading an image.
This method is pretty handy if you are wondering if your new acquaintance is using a fake picture or not.
1. Go to Google Image and click on the camera icon in the right corner of the search bar. A new window will pop up where you will be prompted to upload an image from your computer or from a URL.

 You can either download and save your acquaintance’s Facebook photo and upload it, or you can directly paste his or her photo link in Google Image. If your friend’s photo is private, you can also use the small picture that appears on his or her profile. To get the image link, right-click on the photo and select Copy Image Location if you are under Firefox. You should find similar option for Chrome.

 2. After uploading your image, click on search. If the photo has been taken from the web, Google Image will return all web pages where this photo is present.


 With this powerful method, you can now easily find out who is using a fake profile picture on Facebook or any social-networking  websites.

When you chat with someone on Facebook, and the person read your message, it displays ‘seen’ along with the time the message was read. While you might find this, a pretty cool feature that allows you to know if your friend is ignoring your message, it presents a real privacy concern for many users.

The good news is that there’s some browser plug in out there in the wild that can disable the ‘seen’ feature when you chat with someone on Facebook.

For Firefox users

There are two ways to do it if you are under Firefox browser. If you are using the popular plug-in Adblock, go to Filter Preferences and click on the Custom Filters tab. Alternatively, you can access it via the shortcut CTRL+SHIFT+F.
 Click on Add filter group and assign it a name of your choice. Right-Click on it and choose Show/Hide filters (CTRL+R). Click on the Add Filter button on the top to add the following rule:

/ajax/mercury/change_read_status.php$domain=facebook.com

A little explanation – The URL above gets triggered (in the background) to notify Facebook that you have read a message on Facebook chat. By adding it to Adblock, you basically instructed it to block this URL so that it doesn’t get triggered at all.
Another way to solve this problem is by installing GreaseMonkey followed by Facebook Read Status Disabler plug-in.

For Chrome users

If you are under Chrome, you can install Facebook Unseen. This plug-in offers some flexibility allowing you to toggle between on and off to either enable or disable the plug in. It also provides you with statistics how many messages have gone ‘unseen’.


 By installing the mentioned plug-ins above, you can now take back control of your Facebook privacy to prevent awkward social interactions.
