CISA Urges Service Providers to Provide Transparent Updates During Major IT and OT Outages
CISA and FBI issued guidance urging service providers to deliver timely, transparent communications during major IT and OT outages.
CISA, with the FBI and international partners, released 'Communicating Under Pressure: Best Practices for Service Providers', urging providers to prepare crisis-communication procedures, provide timely status updates during IT/OT outages, and maintain out-of-band communication channels. The guidance warns that disruptions to telecom, cloud, energy, and water services can cascade across critical infrastructure. It aligns with CISA's CI Fortify initiative supporting IT/OT isolation and recovery.
CISA Warns Hackers Exploit 17 Active Directory Techniques to Gain Control of Enterprise Networks
CISA and Five Eyes agencies issued joint guidance detailing 17 Active Directory attack techniques like Kerberoasting and DCSync, with hardening and detection advice.
CISA, the NSA, and cyber agencies from Australia, Canada, the UK, and New Zealand released joint guidance on September 15 covering 17 techniques attackers use to compromise Active Directory, including AD CS, Certificate Services, and Federation Services attacks. Named techniques include Kerberoasting, AS-REP roasting, password spraying, DCSync, NTDS.dit dumping, Golden and Silver Tickets, Golden SAML, and Skeleton Key. Recommendations include minimizing SPN accounts, enforcing AES encryption, disabling NTLM, account lockout thresholds of five attempts, phishing-resistant MFA, and Tier 0 prioritization. The guide also lists Windows event IDs 4769, 4768, 4625, 4771, and 2889 for detecting Kerberoasting and password spraying on domain controllers.
CISA Shares 17 Techniques Used by Hackers to Compromise Active Directory
CISA and five international agencies publish joint guidance detailing 17 techniques attackers use to compromise Microsoft Active Directory environments.
CISA, NSA, and the Australian Signals Directorate's ACSC, with contributions from Canadian, UK, and New Zealand cyber centers, released technical guidance on 17 Active Directory attack techniques. It covers AD Domain Services, AD Certificate Services, and AD Federation Services, including Kerberoasting, DCSync, Golden Ticket, Golden SAML, Skeleton Key, and Shadow Credentials. The guidance recommends treating domain controllers, CAs, AD FS servers, and Entra Connect systems as Tier 0 assets with phishing-resistant MFA, Kerberos pre-authentication enforcement, and disabling NTLM/SMBv1.
