The Cybersecurity and Infrastructure Security Agency (CISA) has issued a warning to the public and private sector about a new wave of cyberattacks from nation-state actors that target critical infrastructure. The attacks are part of a broader campaign that aims to disrupt, damage, or destroy critical infrastructure systems and services.
The CISA warning states that the nation-state actors are using sophisticated techniques and tools to evade detection and attribution, such as:
- Using compromised or hijacked devices to launch attacks from remote locations.
- Using zero-day exploits or previously unknown vulnerabilities to gain access to systems and networks.
- Using malware or ransomware to encrypt or lock data and demand payment for decryption or release.
- Using phishing or social engineering to trick users into revealing sensitive information or credentials.
- Using spoofed or legitimate domains to deliver malicious payloads or redirect users to fake websites.
The CISA warning also provides some examples of the types of critical infrastructure systems and services that are being targeted by the nation-state actors, such as:
- Power grids and energy facilities
- Water supply and distribution systems
- Transportation and communication networks
- Manufacturing and industrial facilities
- Healthcare and medical facilities
- Government and public sector agencies
The CISA warning advises the public and private sector to take some measures to protect their critical infrastructure systems and services from the nation-state attacks, such as:
- Implementing strong security controls and policies for their systems and networks.
- Updating their software and hardware regularly with the latest patches and fixes.
- Educating their employees and users about the risks and best practices of cybersecurity.
- Monitoring their systems and networks for any signs of compromise or activity.
- Reporting any incidents or anomalies to their IT administrators or security vendors.
- Collaborating with other stakeholders in their industry or sector to share information and resources.
