Background for this topic.
Cybersecurity and Infrastructure Security Agency (CISA) is the U.S. Department of Homeland Security agency for reducing cyber and physical risks to critical infrastructure and federal civilian networks. Created by the 2018 CISA Act, it works with government and industry, publishes alerts and guidance, and coordinates assistance during significant incidents. Its direct federal-network role chiefly covers the Federal Civilian Executive Branch, including .gov; private-sector engagement is often voluntary or sector-specific.
Practitioners use CISA advisories and the Known Exploited Vulnerabilities catalog to prioritize patching where exploitation has been observed, and consult applicable directives and incident-response guidance. CISA supports vulnerability reporting and promotes controls such as multifactor authentication, logging, and tested recovery. A CISA alert is an actionable risk signal, not proof every organization is affected; teams should verify product, version, exposure, and obligations.
CISA confirmed today that attackers are actively exploiting a critical remote code execution (RCE) bug patched by Fortinet on Thursday. [...]
Volt Typhoon is positioning itself to physically disrupt and cripple US critical infrastructure by gaining access to operational technology networks in the energy, water, communications, and transportation sectors, according to CISA.
Officials Say Hackers Are Evading Detection on Critical Infrastructure NetworksThe U.S. Cybersecurity and Infrastructure Security Agency urged critical infrastructure owners to patch systems after publishing a warning that Chinese hackers are evading detection and maintaining persistent unauthorized access in U.S. information technology environments.
The Chinese Volt Typhoon cyber-espionage group infiltrated a critical infrastructure network in the United States and remained undetected for at least five years before being discovered, according to a joint advisory from CISA, the NSA, the FBI, and partner Five Eyes agencies. [...]
