Threat Actors Continue to Exploit OT/ICS through Unsophisticated Means
Sep 25, 2024
CISA continues to respond to active exploitation of internet-accessible operational technology (OT) and industrial control systems (ICS) devices, including those in the Water and Wastewater Systems (WWS) Sector. Exposed and vulnerable OT/ICS systems may allow cyber threat actors to use default credentials, conduct brute force attacks, or use other unsophisticated methods to access these devices and cause harm. CISA urges OT/ICS operators in critical infrastructure sectors to apply the recommendations listed in Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity to defend against this activity.

CISA and FBI Release Secure by Design Alert on Eliminating Cross-Site Scripting Vulnerabilities
Sep 17, 2024
Today, CISA and FBI released a Secure by Design Alert, Eliminating Cross-Site Scripting Vulnerabilities, as a part of our ongoing effort to reduce the prevalence of vulnerability classes at scale. Vulnerabilities like cross-site scripting (XSS) continue to appear in software, enabling threat actors to exploit them. However, cross-site scripting vulnerabilities are preventable and should not be present in software products. CISA and FBI urge CEOs and other business leaders at technology manufacturers to direct their technical leaders/teams to review past instances of these defects and create a strategic plan to prevent them in the future. Visit our website to learn more about the principles of Secure by Design, take the Secure by Design Pledge, and stay informed on the latest Secure by Design Alerts.
New CISA Plan Aligns Federal Agencies in Cyber Defense
Sep 16, 2024
Today, the Cybersecurity and Infrastructure Security Agency (CISA) released the Federal Civilian Executive Branch (FCEB) Operational Cybersecurity Alignment (FOCAL) Plan. Developed in collaboration with FCEB agencies, this plan provides standard, essential components of enterprise operational cybersecurity and aligns the collective operational defense capabilities across the federal enterprise. Currently, federal agencies maintain their own networks and system architectures—and they independently manage their cyber risk. CISA’s FOCAL plan aligns the federal enterprise, empowering agencies to better address the dynamic cyber threat environment collectively. The plan recommends actions that substantively advance operational cybersecurity improvements and alignment goals. For additional guidance, visit CISA’s Securing Networks web page.
