CISA Announces Vulnerability Disclosure Policy (VDP) Platform

Jul 30, 2021

Original release date: July 30, 2021CISA has announced the establishment of its Vulnerability Disclosure Policy (VDP) Platform for the federal civilian enterprise, which will allow the Federal Civilian Executive Branch to coordinate with the civilian security research community in a streamlined fashion. The VDP Platform provides a single, centrally managed website that agencies can leverage as the primary point of entry for intaking, triaging, and routing vulnerabilities disclosed by researchers. It enables researchers and members of the general public to find vulnerabilities in agency websites and submit reports for analysis. This new platform allows agencies to gain greater insights into potential vulnerabilities, which will improve their cybersecurity posture. This approach also means  agencies no longer need to develop separate systems to enable vulnerability reporting  and triage of identified vulnerabilities, providing government-wide cost savings that CISA estimates at over $10 million. For more details, see the blog post by CISA’s Executive Assistant Director for Cybersecurity, Eric Goldstein. This product is provided subject to this Notification and this Privacy & Use policy.

Significant Historical Cyber-Intrusion Campaigns Targeting ICS

Jul 20, 2021

Original release date: July 20, 2021Protecting our Nation’s critical infrastructure is the responsibility of federal and state, local, tribal, and territorial (SLTT) governments and owners and operators of that infrastructure. The cybersecurity threats posed to the industrial control systems (ICS) that control and operate critical infrastructure are among the most significant and growing issues confronting our Nation. To raise awareness of the risks to—and improve the cyber protection of—critical infrastructure, CISA and the Federal Bureau of Investigation (FBI) have released a Joint Cybersecurity Advisory as well as updates to five alerts and advisories. These alerts and advisories contain information on historical cyber-intrusion campaigns that have targeted ICS: Joint CISA-FBI Cybersecurity Advisory (CSA): AA21-201A: Gas Pipeline Intrusion Campaign, 2011-2013 Note: CISA released the initial version of this publication to affected stakeholders in 2012. ICS Joint Security Awareness Report: JSAR-12-241-01B: Shamoon/DistTrack Malware (Update B) ICS Advisory: ICSA-14-178-01: ICS Focused Malware – Havex ICS Alert: ICS-ALERT-14-281-01E: Ongoing Sophisticated Malware Campaign Compromising ICS (Update E) ICS Alert: IR-ALERT-H-16-056-01: Cyber-Attack Against Ukrainian Critical Infrastructure Technical Alert: TA17-163A: CrashOverride Malware CISA urges critical infrastructure owners and operators to review the publications listed above and apply the mitigations in Joint CISA-FBI CSA AA21-201A: Gas Pipeline Intrusion Campaign, 2011-2013. CISA also encourages owners and operators to review AR-17-20045: Enhanced Analysis of Malicious Cyber Activity. These products contain threat actor tactics, techniques, and procedures (TTPs); technical indicators; and forensic analysis that critical infrastructure owners and operators can use to reduce their organizations’ exposure to cyber threats. Note: although these publications detail historical activity, the TTPs remain relevant to help network defenders protect against intrusions. CISA encourages critical infrastructure owners and operators to report cyber incidents to CISA. Note: for information on the U.S. Department of State’s reward program for identifying persons who participate in the malicious cyber activities against U.S. critical infrastructure, see the U.S. Department of State press release.

Original release date: July 19, 2021CISA, the Federal Bureau of Investigation (FBI), and the National Security Agency (NSA) have observed increasingly sophisticated Chinese state-sponsored activity targeting U.S. political, economic, military, educational, and critical infrastructure personnel and organizations.
