Some Skype customers have reported that their accounts have been used to send spam instant messages to their contacts. Spam messages include links to sites such as Baidu, LinkedIn and other popular services. If you think your Skype account has been hacked in this way, reset your Microsoft account password. The following steps will also help to secure your account.
Protect your account
To make your account extra secure, set up two-step verification on your Microsoft account. This helps protect you by making it more difficult for someone else to sign in to your account.

Protect your account from spammers
We believe hackers have illegally obtained username and password combinations used on other websites and then tried using them to sign in to Skype. If you re-use credentials on different sites and services, then just one attack on one of these sites can compromise those credentials everywhere else. That’s why we recommend you use a unique username and password combination, and set up two-step verification on your Microsoft account.
