For the most part you should not use Skype. The exception being a media event or with people you know and trust their security levels.
I am not going to say Google is better, but it is what I use “when need be.” The key words being “when need be” For the most part your camera should be covered and only used for common matters.
I have not conducted exploit research on Skype since the Yahoo exploits of 2008. However, every now and again I check to see what exploits are availed in the wild. And there is always some major hole.
Awesomely enough, now there is a handy-dandy automated open source tool to slurp up that last little bits of your data, profiles, contacts, messages, and calls.
I am of course being very jovial . I do not wish to slurp up your data; well… unless need be.
All silliness aside, the tool is useful in some aspects of research and forensics. Of course it should not be used without authorization because it would be a violation of privacy.
