PROTECT YOUR NETWORK SHARES
Any network drive easily accessible from Windows is vulnerable to ransomware. Tightening security means changing your network shared credentials. First, if you’ve set up a user on your NAS that shares the same username and password as your Windows account for ease of access, log into your NAS’s user account settings and change the password to something unique.
Also, make sure you’re not saving network credentials: When you’re next prompted to log on to a network share, make sure the box “Remember my credentials” is left unticked. If—as is likely—you’ve previously saved credentials, type “credentials” into the search box and click “Credential Manager.” You should see entries for each saved network password under “Windows Credentials.” Click the downward arrow button followed by “Remove > Yes.”
If you’re accessing the network share through a third-party app—say your backup tool—you should be able to store your credentials in the app itself, beyond the ransomware’s reach. In Macrium, select “Other Tasks > Edit Defaults > Network.”
