Tip 5: Don’t click on links or open attachments in messages where the source doesn’t seem trustful

Links or attachments in e-mails can be infected with malware. Such malware can infect your device and destroy all data.

It can also spy on you and steal confidential data or money (i.e. e-banking account).

Or it steals personal or business passwords and impersonate your accounts to send spam e-mails or to infect colleagues and friends with malware.

Always be careful when an e-mail has an attachment or a link embedded: Even if the sender seems familiar, always double check before clicking on the attachment or the link. Faking a friend's identity is a powerful method hackers use to inject viruses on your devices.

Download files only from trusted sources. It is common that hackers trick you in visiting fake websites which look as the legitimate website to steal your sensitive information (i.e faking your bank website).

 

Always check if the website is secure by looking at the address bar of your browser:
  

Always keep your own devices up to date and make sure you perform regular backups to reduce the chance of losing information if a malware infects your device.
