1. Enable multifactor authentication (MFA). With credential theft remaining the primary means of infiltrating organizations’ employees and systems, adding an extra layer of protection is essential, especially for particularly sensitive data.
  2. Back up your data. Trend Micro advises businesses to create at least three backup copies in two different file formats, with one of those copies stored offsite. This will limit the impact of systems being locked down by ransomware attackers.
  3. Keep systems up to date. Organisations must ensure all their applications, operating systems, and other software are updated as soon as vendors and developers release patches to reduce the likelihood of exploitation.
  4. Verify emails before opening them. Phishing emails, which entice employees to download malicious attachments or click on malicious links, remain a common means to launch ransomware attacks, Therefore, organisations should ensure they have the strongest possible email protections in place, and train employees on how to detect such emails.
  5. Follow established security frameworks. Trend Micro urged organisations to develop their cybersecurity strategies based around well-regarded security frameworks created by government agencies like the US National Institute of Standards and Technology (NIST) and UK National Cyber Security Centre (NCSC).
