Just opening an email to view it is safe now – although attachments & links in the email can still be dangerous to open. Phishing is one of the most common methods of delivering ransomware. When a user downloads a malicious attachment within a phishing email which contains ransomware, all of the user’s files are encrypted and made inaccessible until ransom is paid.
While it is not always possible to prevent a successful attack, engaging in general security best practices and implementing effective email protection can drastically reduce your risk. Some tips for preventing a successful ransomware attack include:
- Think before you click! Make sure you have confirmed the legitimacy of an email before downloading any attachments it contains.
- Make sure your OS is patched and updated, reducing the chance of vulnerabilities existing that criminals could exploit.
- Back up your files frequently and automatically. This won’t prevent a ransomware attack, but it can reduce the damage caused by one. Be aware that backups are not foolproof: ransomware may sit idle for weeks until it is triggered, potentially destroying backups.
- Keep Your Mail Client, Web Browser, and Operating System Updated
- Invest in a comprehensive, threat-ready email security solution that accurately detects malicious emails - such as ransomware emails - and prevents them from reaching the inbox.
