happening. basically this group trying to raise awareness that snapchat needs to close these gaps in security. >> they say the company was too reluctant to patch the exploit until they knew it was too late. it was more like a red flag saying this is what's going on, we're capable of hacking. >> meanwhile at skype, a similar situation or a different kind of hack? >> there was a different kind of hack. this was done by the syrian electronic army. it said it hacked into skype's social media account. it hacked into twitter and facebook posting messages. and this is a group that's attacked cyberattacked the bbc and "the new york times" in the past. this was apparently linked to the revelations in the past year from edward snowden, that skype was part of the nsa monitoring service, quote, spying on americans. skype is owned by microsoft. what this group wound up doing was posting information of steve ballmer, the retiring chief executive of microsoft.
