When I logged onto Skype, I had a new name, and a new contact, both of which were Ivan something. I immediately started chatting with Ivan, who told me that there was a weakness in the Skype login security, which he tried to exploit.
I changed my password to another Medium to Strong password, and a few minutes later my name was again changed to “Anders xoxo Hafreager”, and a message that he had hacked me again.
I still don’t know what he did or how he did it.
