    In this Special Episode, Maria Varmazis and Dave Bittner are joined by friend of the show, Brandon Karpf, to unpack a new bipartisan congressional investigation into the lingering presence of Chinese state-owned telecommunications companies inside U.S. internet infrastructure. The House Select Committee on China says China Mobile, China Unicom, and China Telecom remain deeply embedded in American networks even after federal regulators denied or revoked their authority to provide certain telecommunications services over national security concerns. The investigation found that restrictions imposed by the FCC limited what the companies could sell, but did not necessarily remove their equipment, network connections, or commercial relationships from the U.S. internet ecosystem.

    When hackers control the clock. [T-Minus: Space-Cyber Briefing]
    2026/09/06
    The accurate timing data from spacecraft has become an invaluable tool for nearly every critical infrastructure sector and a greater target for malicious actors. Host Maria Varmazis and ⁠Andy Davis⁠, Global Research Director at the NCC Group, discuss the importance of timing in space. The two look at how timing systems have continued to grow more important in everyday life and why attackers have begun to increasingly exploit these critical services. Key sources: GPS: A backbone for critical infrastructure. Spoofing ships, jamming drones: how GPS manipulation confuses and compromises. Like what you heard?

  • RMM-ber this ransomware. [Research Saturday]

    RMM-ber this ransomware. [Research Saturday]
    2026/09/05
    Ismael Valenzuela, Vice President of Labs, Threat Research and Intelligence at Arctic Wolf, sits down with Dave to discuss their work tracking Anubis. Arctic Wolf Labs details a series of 2026 Anubis ransomware intrusions, revealing affiliates using stolen VPN credentials and exploiting CitrixBleed 2 to gain initial access. Attackers then blended into legitimate IT activity by deploying RMM tools, using RDP and PsExec for lateral movement, stealing credentials, and establishing tunnels and proxies for persistence and exfiltration. The research highlights a repeatable attack chain defenders can disrupt before encryption, from suspicious remote access and unauthorized RMM deployment to credential theft, security-tool tampering, and ransomware execution. The research and executive brief can be found here: ⁠From CitrixBleed 2 to Cloudflared: The Tools and Techniques Behind Anubis Ransomware Attacks
