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. Tune in to understand the key findings, and download the full report for more details.

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.

Ransomware is not new, but the ransomware of today is very different from the ransomware of 1989. Today’s episode doubles as a history lesson, as Adam and Cristian look back at how a prolific global threat has evolved over the decades.

Gone are the days of malware arriving on floppy disks and victims waiting weeks to restore their systems in exchange for $200 ransom payments. “The early days of viruses were weird,” Adam points out. But much has changed since then. Several factors — the advent of cryptocurrency, the rise of enterprise targeting, and the shift to ransomware as a service — have caused the threat to transform. Today’s adversaries run ransomware like a business and collect hundreds of millions of dollars in payments.

The hosts reflect on the first ransomware to hit a business, the first to make news headlines, and the first major botnet operator to deploy ransomware, among other key events. Tune in for a discussion that spans years of ransomware evolution, highlights the key adversaries involved, and explains how businesses can defend themselves as the threat landscape continues to change.

This week’s episode arrives as Adam and Cristian are gearing up for Fal.Con, CrowdStrike’s annual event taking place next week in Las Vegas. They’ll be recording a live episode on some fascinating LLM research presented at the show, so stay tuned for that in a couple of weeks. Amid their prep, they took the time to sit down for a conversation starting with a simple prompt: What are today’s security leaders and practitioners talking about? Their discussion sheds light on the industries hardest hit by nation-state and eCrime activity and explores why some sectors, like technology and telecommunications, are seeing a sharp spike in targeted intrusions while others are facing an increase in cybercrime. Tune in to learn about shifts in Chinese cyber activity, what happens when an adversary sees another adversary in a target environment, and whether modern tech innovations will drive changes in cyber espionage.

This year at Black Hat, the topic of AI was everywhere — from hallway chats to the expo floor. Adam and Cristian took a break from the action for a rare in-person conversation about how adversaries are weaponizing AI, how defenders are using agentic AI, and what we should all be thinking about as AI evolves as an offensive and defensive tool. The AI threat is real, and advanced adversaries in particular are using it to their advantage. They’re improving the wording in social engineering attacks, creating deepfakes in fraudulent job interviews, and targeting victims on a more personal level. FAMOUS CHOLLIMA is an example of one adversary “using it for everything,” the hosts say. SCATTERED SPIDER is another adversary to watch. On the other side, defenders are adopting agentic AI to expedite their response. Adam and Cristian explore the importance of protecting AI workloads, the potential for insider threats with AI models, and the growing need for AI governance and security guardrails. If AI is monitoring security services, they ask, who guards the guardian? Tune in for an in-depth conversation on what AI is really capable of — and stick around for a sneak peek of an upcoming guest episode, where a guest joins to discuss young adversaries moving from online gaming to organized cybercrime.

In the first half of 2025 alone, cloud intrusions were up 136% compared to all of 2024. China was a big driver — CrowdStrike saw a 40% year-over-year surge in intrusions from suspected cloud-conscious China-nexus threat actors. In the government sector, interactive intrusions increased 71%, and targeted intrusion activity jumped 185%.

The CrowdStrike OverWatch threat hunting team has a firsthand look at how adversaries are changing their techniques. In the CrowdStrike 2025 Threat Hunting Report, published today, the team shares observations, trends, and shifts seen in its threat hunting and adversary engagements over the past 12 months.

In this episode, Adam and Cristian dive deep into the report’s key findings and put them into context. They explore why the use of malware is going down (and why it won’t go away), unpack the rise in government intrusions, and explain the role of generative AI (GenAI) in today’s threat landscape. They examine the rise of prolific adversaries such as SCATTERED SPIDER and FAMOUS CHOLLIMA and discuss the techniques organizations can use to stop them.

Below are more key stats from this year’s report:

• 73% of all interactive intrusions were eCrime
• 81% of interactive intrusions were malware-free
• In the first half of 2025, voice phishing (vishing) attacks surpassed the total number seen in 2024
• FAMOUS CHOLLIMA insiders infiltrated 320+ companies in the last 12 months — a 220% year-over-year increase — by using GenAI throughout hiring and employment
