CISA Adds One Known Exploited Vulnerability to Catalog 4 Aug 2022, 9:28 pm

Original release date: August 4, 2022

CISA has added one new vulnerability to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. These types of vulnerabilities are a frequent attack vector for malicious cyber actors and pose significant risk to the federal enterprise. Note: to view the newly added vulnerabilities in the catalog, click on the arrow in the "Date Added to Catalog" column, which will sort by descending dates. 

Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities established the Known Exploited Vulnerabilities Catalog as a living list of known CVEs that carry significant risk to the federal enterprise. BOD 22-01 requires FCEB agencies to remediate identified vulnerabilities by the due date to protect FCEB networks against active threats. See the BOD 22-01 Fact Sheet for more information.

Although BOD 22-01 only applies to FCEB agencies, CISA strongly urges all organizations to reduce their exposure to cyberattacks by prioritizing timely remediation of Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the Catalog that meet the specified criteria.

CISA and ACSC Release Top 2021 Malware Strains 2 Aug 2022, 3:36 pm

Original release date: August 2, 2022 | Last revised: August 4, 2022

CISA and the Australian Cyber Security Centre (ACSC) have published a joint Cybersecurity Advisory on the top malware strains observed in 2021. Malicious cyber actors often use malware to covertly compromise and then gain access to a computer or mobile device. As malicious cyber actors have been using most of these top malware strains for more than five years, organizations have opportunities to better prepare, identify, and mitigate attacks from these strains.  

CISA and ACSC encourage organizations to apply the recommendations in the Mitigations sections of the joint CSA. These mitigations include prioritizing patching all systems with known exploited vulnerabilities, enforcing multifactor authentication (MFA), securing remote desktop protocol (RDP) and other risky services, making offline backups of your data, and providing end-user awareness and training about social engineering and phishing. The appendix contains detection signatures organizations can employ in defending their networks. For more information on preventing malicious cyber actors from using 2021 top malware strains to exploit vulnerabilities, see:

•    CISA’s Known Exploited Vulnerabilities Catalog 
•    CISA’s Cyber Hygiene Services
•    CISA’s Choosing and Protecting Passwords
•    ACSC’s Implementing Multi-Factor Authentication
