Remediation

  • Block all threat indicators at your respective controls.
  • Search for Indicator of compromise (IOCs) in your environment utilizing your respective security controls
  • Maintain cyber hygiene by updating your anti-virus software and implement patch management lifecycle.
  • Maintain Offline Backups – In a ransomware attack, the adversary will often delete or encrypt backups if they have access to them. That’s why it’s important to keep offline (preferably off-site), encrypted backups of data and test them regularly.
  • Emails from unknown senders should always be treated with caution.
  • Never trust or open ” links and attachments received from unknown sources/senders.
