CISA and Partners Release Updated Advisory on Scattered Spider Group

CISA, along with the Federal Bureau of Investigation, Canadian Centre for Cyber Security, Royal Canadian Mounted Police, the Australian Cyber Security Centre’s Australian Signals Directorate, and the Australian Federal Police and National Cyber Security Centre, released an updated joint Cybersecurity Advisory on Scattered Spider—a cybercriminal group targeting commercial facilities sectors and subsectors. This advisory provides updated tactics, techniques, and procedures (TTPs) obtained through FBI investigations conducted through June 2025.

Scattered Spider threat actors have been known to use various ransomware variants in data extortion attacks, most recently including DragonForce ransomware. While Scattered Spider often changes TTPs to remain undetected, some TTPs remain consistent. These actors frequently use social engineering techniques such as phishing, push bombing, and subscriber identity module swap attacks to obtain credentials, install remote access tools, and bypass multi-factor authentication.

The Mitigations section of the Scattered Spider joint Cybersecurity Advisory offers critical infrastructure organizations and commercial facilities recommendations to fortify their defenses.

CISA Releases Five Industrial Control Systems Advisories

CISA released five Industrial Control Systems (ICS) advisories on July 29, 2025. These advisories provide timely information about current security issues, vulnerabilities, and exploits surrounding ICS.

CISA encourages users and administrators to review newly released ICS advisories for technical details and mitigations.

CISA Releases Part One of Zero Trust Microsegmentation Guidance

CISA released Microsegmentation in Zero Trust, Part One: Introduction and Planning as part of its ongoing efforts to support Federal Civilian Executive Branch (FCEB) agencies implementing zero trust architectures (ZTAs). 

This guidance provides a high-level overview of microsegmentation, focusing on its key concepts, associated challenges and potential benefits, and includes recommended actions to modernize network security and advance zero trust principles.

Microsegmentation is a critical component of ZTA that reduces the attack surface, limits lateral movement, and enhances visibility for monitoring smaller, isolated groups of resources.

While the guidance focuses on FCEB references, its principles are applicable to any organization. As part of its Journey to Zero Trust series, CISA plans to release a subsequent technical guide to offer detailed implementation scenarios and technical considerations for implementation teams. Visit our Zero Trust webpage for more information and resources.

CISA Adds Three Known Exploited Vulnerabilities to Catalog

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

  • CVE-2025-20281 Cisco Identity Services Engine Injection Vulnerability
  • CVE-2025-20337 Cisco Identity Services Engine Injection Vulnerability
  • CVE-2023-2533 PaperCut NG/MF Cross-Site Request Forgery (CSRF) 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 KEV 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 KEV Catalog vulnerabilities as part of their vulnerability management practice. CISA will continue to add vulnerabilities to the catalog that meet the specified criteria.
