Remediation

• Maintain cyber hygiene by updating your anti-virus software and implementing a patch management lifecycle.
• Emails from unknown senders should always be treated with caution.
• Never trust or open links and attachments received from unknown sources/senders.
• Keep your software up to date. Software updates often include security patches that can help to protect your systems from known vulnerabilities.
• Use strong passwords and multi-factor authentication. This will make it more difficult for attackers to gain access to your systems.
• Back up your data regularly. This will help you to recover if your systems are encrypted by ransomware.
• Deploy robust endpoint security solutions, including antivirus, anti-malware, and intrusion detection systems, to detect and prevent threats like LockBit ransomware.
• Immediately disconnect or isolate the compromised systems from the network to prevent the malware from spreading further. This may involve shutting down affected servers or segments of the network.
• Conduct a thorough investigation to determine the extent of the breach, including identifying which systems and data were compromised.
• Develop a long-term cybersecurity strategy to prevent future incidents, including investing in advanced threat detection and response capabilities.
