As the nation’s cyber defense agency, CISA stands ready to help organizations prepare for, respond to, and mitigate the impact of cyberattacks. CISA’s Shields Up campaign webpage provides recommendations, products, and resources to increase organizational vigilance and keep stakeholders informed about cybersecurity threats and destructive exploits against critical infrastructure.
Every organization—large and small—should adopt a heightened posture when it comes to cybersecurity and protect their most critical assets against disruptive cyber incidents. CISA also encourages our stakeholders to voluntarily share information about cyber-related events that could help mitigate current or emerging cybersecurity threats to critical infrastructure.
CISA urges everyone to protect themselves online and adopt a heightened posture when it comes to cybersecurity. CISA offers the following guidance for individuals, organizations, and leadership to enhance online security.

Ransomware is a form of malware that encrypts files on device, rendering any files and the systems that rely on them unusable. Malicious actors then demand ransom in exchange for decryption. Ransomware incidents have become increasingly prevalent among the Nation’s state, local, tribal, and territorial (SLTT) government entities and critical infrastructure organizations.
Paying ransom will not ensure your data is decrypted or that your systems or data will no longer be compromised. CISA, MS-ISAC, and other federal law enforcement do not recommend paying ransom. In addition, attackers have begun following their ransom demands to decrypt the data with a follow-on extortion demand to keep data private.
