Adversary Universe Podcast

In November 2025, a major public-private sector collaboration took down three significant malware networks. Operation Endgame involved law enforcement agencies from six EU countries, Australia, Canada, the U.K., and the U.S., along with Europol and 30 private sector partners, including CrowdStrike. The dismantled infrastructure consisted of hundreds of thousands of infected computers containing several million stolen credentials. Operation Endgame was a critical disruption of adversary operations — but it wasn’t the first. Law enforcement has for years sought to take down adversary infrastructure and often partners with private sector organizations like CrowdStrike to inform their operations. By disrupting the tools and processes threat actors rely on, these takedowns raise the cost for adversaries and make it harder for them to operate. As Adam and Cristian discuss in this episode, takedowns require careful planning and constant innovation. Adversaries are always finding new techniques and tools, and law enforcement must do the same. While disruption may slow them down, threat actors are often quick to pivot and find new ways to achieve their goals. In this episode, we examine how law enforcement takedowns disrupt adversary operations, how adversaries respond, where the private sector provides support, and what this all means for organizations facing modern threats.

Not all cybercrimes are resolved. Some threat groups disappear completely, and some malware is never seen again. But sometimes, a long-dormant case is cracked open and elusive answers are found. Tillmann Werner, VP of Intelligence Production at CrowdStrike, has been a member of the CrowdStrike Intelligence team since 2012 and has analyzed many of these cold cases. In this episode, he joins Adam to chat about unresolved cyberattacks, the adversaries behind them, and cases that remained inactive for years before new technology or data allowed experts to close them. While it’s frustrating to close a file without success, Tillmann says, the evolution of technology and proliferation of data often help solve old cases that have collected dust. Tune in to hear Adam and Tillmann look back at decades-old eCrime and nation-state campaigns, some of which now have answers — and others that remain a mystery. 

CrowdStrike research into AI coding assistants reveals a new, subtle vulnerability surface: When DeepSeek-R1 receives prompts the Chinese Communist Party (CCP) likely considers politically sensitive, the likelihood of it producing code with severe security flaws increases by up to 50%. Stefan Stein, manager of the CrowdStrike Counter Adversary Operations Data Science team, joined Adam and Cristian for a live recording at Fal.Con 2025 to discuss how this project got started, the methodology behind the team’s research, and the significance of their findings. The research began with a simple question: What are the security risks of using DeepSeek-R1 as a coding assistant? AI coding assistants are commonly used and often have access to sensitive information. Any systemic issue can have a major and far-reaching impact.  It concluded with the discovery that the presence of certain trigger words — such as mentions of Falun Gong, Uyghurs, or Tibet — in DeepSeek-R1 prompts can have severe effects on the quality and security of the code it produces. Unlike most large language model (LLM) security research focused on jailbreaks or prompt injections, this work exposes subtle biases that can lead to real-world vulnerabilities in production systems. Tune in for a fascinating deep dive into how Stefan and his team explored the biases in DeepSeek-R1, the implications of this research, and what this means for organizations adopting AI. 

Europe is a prime target for global adversaries. There is a strong emphasis on eCrime across the region as well as a rise in hacktivism and espionage stemming from ongoing conflicts. The CrowdStrike 2025 European Threat Landscape Report breaks down these trends. In this episode, Adam and Cristian cover the highlights. They start with cybercrime, a major theme of the report. The five most targeted European nations were the U.K., Germany, Italy, France, and Spain, which also represent the region’s largest economies (excluding Russia). The most targeted sectors were manufacturing, professional services, technology, industrials and engineering, and retail. Adam explains how eCrime threat actors are looking for victims with a high need to stay operational. “With manufacturing, if they’re knocked offline because of ransomware, they can count the downtime in dollars and cents,” he shares as an example. On the nation-state front, Russia is top of mind. Since its invasion of Ukraine in 2022, many Russian threat actors who operated globally are more focused on Ukraine and areas related to the conflict. Adam and Cristian discuss reports of North Korean threat actors supporting the Russians with weapons and personnel, North Korea targeting Ukraine, and the tactics and techniques that stand out most. The European threat landscape is crowded and complex.

In the Asia Pacific and Japan (APJ) region, a burgeoning set of threat actors is emerging with a different language set, distinct tools, and an ecosystem where they interact with adversaries across the threat landscape. The CrowdStrike 2025 APJ eCrime Landscape Report explores the trends and issues facing organizations operating in this part of the world. For example, criminal groups in APJ are focused on opportunistic big game hunting and primarily target organizations in manufacturing, technology, industrials and engineering, financial services, and professional services. The sale of phishing kits is popular, with some going for up to $1 million. These threat actors prefer phishing, spam campaigns, and remote access toolkits to enable their operations. And they often find them on thriving Chinese-language marketplaces, which enable the sale of illicit services. While Eastern Europe is typically known as a hotbed of eCrime activity, the APJ region is one to watch. Tune in to hear Adam and Cristian discuss the key adversaries operating in the region, the threats that stand out to them, and how defenders can stay safe.
