Files on a central cloud server used by the ransomware group highlight a systematic, aggressive attack on network backups as a key TTP.

The ransomware gang, known for double-extortion attacks, had access to a critical Cisco firewall vulnerability weeks before it was publicly disclosed.

CISA has added five new vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog, based on evidence of active exploitation. CVE-2025-31277 Apple Multiple Products Buffer Overflow Vulnerability CVE-2025-32432 Craft CMS Code Injection Vulnerability CVE-2025-43510 Apple Multiple Products Improper Locking Vulnerability CVE-2025-43520 Apple Multiple Products Classic Buffer Overflow Vulnerability CVE-2025-54068 Laravel Livewire Code 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 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.

CISA and the Federal Bureau of Investigation released a Public Service Announcement (PSA) warning about ongoing phishing campaigns by cyber actors associated with the Russian Intelligence Services targeting commercial messaging applications (CMAs). These campaigns aim to bypass encryption to compromise to individual user accounts with targets including current and former U.S. government officials, military personnel, political figures, and journalists. Evidence shows that cyber actors have been able to compromise individual CMA accounts, but not encryption of the applications themselves. The actors’ global campaigns have resulted in unauthorized access to thousands of individual CMA accounts to view the victims’ messages and contact lists, send messages, and conduct additional phishing against other CMA accounts. CISA and FBI urge CMA users to review the PSA, follow recommended cybersecurity practices, and remain vigilant for suspicious activity.

Ensure usage of user management and password features. User rights are enabled by default and forced to create a strong password at first use. Deactivate the Webserver after use when not needed. Use encrypted communication links. Setup network segmentation and implement a firewall to block all unauthorized access to ports 80/HTTP and 443/HTTPS. Use VPN (Virtual Private Networks) tunnels if remote access is required.

Recommended Practices CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as: Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet. Locate control system networks and remote devices behind firewalls and isolating them from business networks. When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs). Recognize VPNs may have vulnerabilities, should be updated to the most recent version available, and are only as secure as the connected devices. CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures. CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies. CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets. Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov in the technical information paper, ICS-TIP-12-146-01B--Targeted Cyber Intrusion Detection and Mitigation Strategies. Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents. CISA also recommends users take the following measures to protect themselves from social engineering attacks: Do not click web links or open attachments in unsolicited email messages. Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams. Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks. No known public exploitation specifically targeting this vulnerability has been reported to CISA at this time.
