CISA and Partners Release Updated Advisory on Scattered Spider Group
Jul 29, 2025
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 Adds Three Known Exploited Vulnerabilities to Catalog
Jul 28, 2025
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.
