Mullvad protected against Microsoft security issue
A serious security issue that can negatively affect VPN users has been made public by online profile ValdikSS. If you are using Microsoft Edge / IE or Outlook while connecting through a VPN, a malicious website or email can make Windows leak a hashed version of your Microsoft account password, among other things.
Mullvad VPN mitigated the issue last week, after an early warning from ValdikSS, by blocking a number of ports on its servers, preventing the leak.
