Recommended Steps for Prevention

  • Apply the Microsoft patch for the MS17-010 SMB vulnerability dated March 14, 2017.
  • Enable strong spam filters to prevent phishing e-mails from reaching the end users and authenticate in-bound e-mail using technologies like Sender Policy Framework (SPF), Domain Message Authentication Reporting and Conformance (DMARC), and DomainKeys Identified Mail (DKIM) to prevent e-mail spoofing.
  • Scan all incoming and outgoing e-mails to detect threats and filter executable files from reaching the end users.
  • Ensure anti-virus and anti-malware solutions are set to automatically conduct regular scans.
  • Manage the use of privileged accounts. Implement the principle of least privilege. No users should be assigned administrative access unless absolutely needed. Those with a need for administrator accounts should only use them when necessary.
  • Configure access controls including file, directory, and network share permissions with least privilege in mind.
  • If a user only needs to read specific files, they should not have write access to those files, directories, or shares.
  • Disable macro scripts from Microsoft Office files transmitted via e-mail. Consider using Office Viewer software to open Microsoft Office files transmitted via e-mail instead of full Office suite applications.
  • Develop, institute and practice employee education programs for identifying scams, malicious links, and attempted social engineering.
  • Have regular penetration tests run against the network. No less than once a year. Ideally, as often as possible/practical.
  • Test your backups to ensure they work correctly upon use.
