Remediation

  • Block all threat indicators at your respective controls.
  • Search for Indicators of compromise (IOCs) in your environment utilizing your respective security controls
  • Do not download documents attached in emails from unknown sources and strictly refrain from enabling macros when the source isn’t reliable.
  • Enable antivirus and anti-malware software and update signature definitions in a timely manner. Using multi-layered protection is necessary to secure vulnerable assets
  • Along with network and system hardening, code hardening should be implemented within the organization so that their websites and software are secure. Use testing tools to detect any vulnerabilities in the deployed codes.
