In a joint security advisory, ‘2021 Trends Show Increased Globalized Threat of Ransomware’, various US, UK, and Australian security agencies have warned about the high level of threat that critical infrastructure organizations and others face due to a global increase in sophisticated, high-impact, ransomware incidents.
In the advisory CISA, the Federal Bureau of Investigation (FBI), the National Security Agency (NSA), the Australian Cyber Security Centre (ACSC), and the United Kingdom’s National Cyber Security Centre (NCSC-UK) detail observed patterns and trends as well as mitigation recommendations to help network defenders reduce their risk of compromise by ransomware.
According to the advisory actions that can be taken to protect against ransomware include:
- Update your operating system and software.
- Implement user training and phishing exercises to raise awareness about the risk of suspicious links and attachments.
- If you use Remote Desktop Protocol (RDP), secure and monitor it.
- Make an offline backup of your data.
- Use multifactor authentication (MFA).
