NSA, CISA, FBI, and International Partners Release Cybersecurity Advisory on “Fast Flux,” a National Security Threat
Apr 3, 2025
Today, CISA—in partnership with the National Security Agency (NSA), Federal Bureau of Investigation (FBI), Australian Signals Directorate’s Australian Cyber Security Centre (ASD’s ACSC), Canadian Centre for Cyber Security (CCCS), and New Zealand’s National Cyber Security Centre (NCSC-NZ)—released joint Cybersecurity Advisory Fast Flux: A National Security Threat (PDF, 841 KB). This advisory warns organizations, internet service providers (ISPs), and cybersecurity service providers of the ongoing threat of fast flux enabled malicious activities and provides guidance on detection and mitigations to safeguard critical infrastructure and national security. “Fast flux” is a technique used to obfuscate the locations of malicious servers through rapidly changing Domain Name System (DNS) records associated with a single domain name. This threat exploits a gap commonly found in network defenses, making the tracking and blocking of malicious fast flux activities difficult. The authoring agencies strongly recommend adopting a multi-layered approach to detection and mitigation to reduce risk of compromise by fast flux-enabled threats. Service providers, especially Protective DNS providers (PDNS), should track, share information about, and block fast flux as part of their provided cybersecurity services. Government and critical infrastructure organizations should close this ongoing gap in network defenses by using cybersecurity and PDNS services that block malicious fast flux activity. For more information on PDNS services, see Selecting a Protective DNS Service.

CISA Releases Malware Analysis Report on RESURGE Malware Associated with Ivanti Connect Secure
Mar 28, 2025
CISA has published a Malware Analysis Report (MAR) with analysis and associated detection signatures on a new malware variant CISA has identified as RESURGE. RESURGE contains capabilities of the SPAWNCHIMERA[1] malware variant, including surviving reboots; however, RESURGE contains distinctive commands that alter its behavior. These commands: Create a web shell, manipulate integrity checks, and modify files. Enable the use of web shells for credential harvesting, account creation, password resets, and escalating permissions. Copy the web shell to the Ivanti running boot disk and manipulate the running coreboot image. RESURGE is associated with the exploitation of CVE-2025-0282 in Ivanti Connect Secure appliances. CVE-2025-0282 is a stack-based buffer overflow vulnerability in Ivanti Connect Secure, Policy Secure, and ZTA Gateways. CISA added CVE-2025-0282 to its Known Exploited Vulnerabilities Catalog on January 8, 2025. For more information on the abovementioned malware variants and YARA rules for detection, see: MAR-25993211.R1.V1.CLEAR. For a downloadable copy of the SIGMA rule associated with this MAR, see: AR25-087A SIGMA YAML. CISA urges users and administrators to implement the following actions in addition to the Mitigation Instructions for CVE-2025-0282: For the highest level of confidence, conduct a factory reset. For Cloud and Virtual systems, conduct a factory reset using an external known clean image of the device. See Ivanti’s Recommended Recovery Steps for more information, including how to conduct a factory reset. Reset credentials of privileged and non-privileged accounts. Reset passwords for all domain users and all local accounts, such as Guest, HelpAssistant, DefaultAccount, System, Administrator, and krbtgt. The krbtgt account is responsible for handling Kerberos ticket requests as well as encrypting and signing them. The krbtgt account should be reset twice because the account has a two-password history. The first account reset for the krbtgt needs to be allowed to replicate prior to the second reset to avoid any issues. See CISA’s Eviction Guidance for Networks Affected by the SolarWinds and Active Directory/M365 Compromise for more information. Although tailored to Federal Civilian Executive Branch (FCEB) agencies compromised in the 2020 SolarWinds Orion supply chain compromise, the steps are applicable to organizations with Windows AD compromise. Review access policies to temporarily revoke privileges/access for affected devices. If it is necessary to not alert the attacker (e.g., for intelligence purposes), then privileges can be reduced for affected accounts/devices to “contain” them. Reset the relevant account credentials or access keys if the investigation finds the threat actor’s access is limited to non-elevated permissions. Monitor related accounts, especially administrative accounts, for any further signs of unauthorized access. Organizations should report incidents and anomalous activity related to information found in the malware analysis report to CISA’s 24/7 Operations Center at Report@cisa.gov or (888) 282-0870. Malware submissions can be made directly to Malware Nextgen at https://malware.cisa.gov.
