We have already seen Microsoft deal with a major security issue in Skype earlier this month, when an exploit that allowed anyone to access any Skype account was quickly fixed within a few hours
. However, a problem that has been an issue with Skype much longer is now getting Microsoft's attention.
Basically, this feature is based on the default setting in Skype that allows its users to receive unsolicited calls from other Skype accounts. Hackers have been using this feature for some time to call Skype users and direct them to scam websites. Those who use Skype have already indicated they don't want to mess with changing the default on unsolicited calls.
