A 2004 article ( PDF) in Hakin9 magazine described how to intercept Yahoo messages using the tcpdump utility. Yahoo users' vulnerability to snoops has been public knowledge for at least a decade. "Whether it's the lack of encryption in Webmail, or the video issue, Yahoo has ignored repeated warnings from researchers, from human rights activists." "We have ample evidence now that Yahoo doesn't really care about security or the confidentiality of its customers' communications," said Chris Soghoian, principal technologist at the ACLU's Speech, Privacy and Technology Project. SSL and similar technologies, if implemented properly, are designed to be proof against even the NSA's aggressive attempts to vacuum up petabytes of Internet traffic. That was possible because Yahoo has lagged far behind rivals Google and Microsoft in adopting a standard technique known as SSL that scrambles information before it's transmitted. A surveillance system code-named Optic Nerve "intercepted and stored the webcam images of millions of Internet users not suspected of wrongdoing," the paper said, citing documents provided by Snowden. These privacy problems were highlighted by a Guardian article Thursday, which revealed that spy agencies were eavesdropping on Yahoo's unencrypted video chats.
