Apr 11, 2016
Earlier this year, Facebook came across a bunch of duplicate SSL certificates for some of its own domains and revoked them immediately with the help of its own Certificate Transparency Monitoring Tool service.

The Online Privacy relies heavily on SSL/TLS Certificates and encryption keys to protect millions of websites and applications. As explained in our  previous article on The Hacker News , the current Digital Certificate Management system and trusted Certificate Authorities (CAs) are not enough to prevent misuse of SSL certificates on the internet.

Meta on Thursday revealed that it disrupted three covert influence operations originating from Iran, China, and Romania during the first quarter of 2025. "We detected and removed these campaigns before they were able to build authentic audiences on our apps," the social media giant said in its quarterly Adversarial Threat Report. This included a network of 658 accounts on Facebook, 14 Pages, and two accounts on Instagram that targeted Romania across several platforms, including Meta's services, TikTok, X, and YouTube.

Nov 12, 2019
It appears that Facebook at the center of yet another issue involving privacy. Reportedly, multiple iPhone users have come forward on social media complaining that the Facebook app secretly activates their smartphone's camera in the background while they scroll through their Facebook feeds or looking at the photos on the social network. As shown in the Twitter videos below, when users click on an image or video on the social media to full screen and then return it back to normal, an issue with the Facebook app for iOS slightly shifts the app to the right. It opens a space on the left from where users can see the iPhone's camera activated in the background. However, at this moment, it's not clear if it's just an UI bug where Facebook app incorrectly but only accesses the camera interface, or if it also records or uploads something, which, if proven right, would be the most disastrous moment in Facebook's history. Found a @facebook #security & #pri...

Facebook and intermediate layer Many times you have seen this "use this application and find out who visits your profile, right?, Well, this will always be a  fake,  because Facebook is designed in a way that makes it impossible. If you look, when you go up a photo like the profile, it is resized, compressed, and stored on Facebook's own server. Actually, there are hundreds of servers, which form what is called a CDN . An example of profile photo: https://profile...
