 ​CISA has added three new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation.

CVE-2024-23113 Fortinet Multiple Products Format String Vulnerability
CVE-2024-9379 Ivanti Cloud Services Appliance (CSA) SQL Injection Vulnerability
CVE-2024-9380 Ivanti Cloud Services Appliance (CSA) OS Command Injection Vulnerability

These types of vulnerabilities are frequent attack vectors for malicious cyber actors and pose significant risks to the federal enterprise.
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 Common Vulnerabilities and Exposures (CVEs) that carry significant risk to the federal enterprise. BOD 22-01 requires Federal Civilian Executive Branch (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.

 ​Today, CISA and the Federal Bureau of Investigation (FBI) released joint fact sheet, How to Protect Against Iranian Targeting of Accounts Associated with National Political Organizations. This fact sheet provides information about threat actors affiliated with the Iranian Government’s Islamic Revolutionary Guard Corps (IRGC) targeting and compromising accounts of Americans to stoke discord and undermine confidence in U.S. democratic institutions.
IRGC actors have previously gained and continue to seek access to personal and business accounts using social engineering techniques by targeting victims across email and chat. This fact sheet includes steps that individuals and organizations can take to enhance their security and resilience to protect themselves against the common techniques used by these cyber actors.
CISA and FBI strongly recommend all individuals and organizations associated with national political organizations apply the mitigations in this fact sheet, including protecting their sensitive accounts with phishing-resistant multifactor authentication (MFA). 
Election infrastructure stakeholders and the public can find more resources on how to protect against cyber and physical threats at #Protect2024. CISA encourages organizations to review its Iran Cyber Threat webpage for advisories and actions to defend their networks.

 ​As hurricanes and other natural disasters occur, CISA urges individuals to remain on alert for potential malicious cyber activity. Fraudulent emails and social media messages—often containing malicious links or attachments—are common after major natural disasters. Exercise caution in handling emails with hurricane-related subject lines, attachments, or hyperlinks. In addition, be wary of social media pleas, texts, or door-to-door solicitations relating to severe weather events. Before responding, ensure hurricane-related guidance is from trusted sources, such as local officials and disaster response organizations, including Federal Emergency Management Agency (FEMA) and DHS’s Ready.gov.
CISA encourages users to review the following resources to avoid falling victim to malicious cyber activity: 

Federal Trade Commission’s Staying Alert to Disaster-related Scams and Before Giving to a Charity, 
Consumer Financial Protection Bureau’s Frauds and Scams, 
FEMA’s Disaster Fraud guidance, and 
CISA’s Phishing Guidance, Stopping the Attack Cycle at Phase One to help organizations reduce likelihood and impact of successful phishing attacks.
