Fake Digital Certificates Found in the Wild While Observing Facebook SSL Connections
A Group of researchers, Lin-Shung Huang , Alex Ricey , Erling Ellingseny and Collin Jackson, from the Carnegie Mellon University in collaboration with Facebook have analyzed more than 3 million SSL connections and found strong evidence that at least 6;845 (0:2%) of them were in fact tampered with forged certificates i.e. self-signed digital certificates that aren't authorized by the legitimate website owners, but will be accepted as valid by most browsers.
