Talos Takes

What separates organizations that successfully fend off ransomware from those that don’t? What were the top threats facing organizations? Can we (pretty please) get a sneak peek into the 2025 Year in Review?Amy is joined by Dave Liebenberg, Strategic Analysis Team Lead, to break down key findings from Q4 2025’s Cisco Talos Incident Response Quarterly Trends Report. From the top threats facing organizations — like the persistent exploitation of public-facing applications and the rise of new vulnerabilities such as Oracle EBS and React2Shell — to the unexpected drop in ransomware cases, this episode is packed with useful info. Episode resources:Q4 2025 Quarterly Trends Report: https://blog.talosintelligence.com/ir-trends-q4-2025/Qilin blog: https://blog.talosintelligence.com/uncovering-qilin-attack-methods-exposed-through-multiple-cases/Cybersecurity on a Budget blog: https://blog.talosintelligence.com/cybersecurity-on-a-budget-strategies-for-an-economic-downturn/

Step into the fascinating world of cryptography. Host Amy Ciminnisi sits down with Yuri Kramarz from Cisco Talos Incident Response and Tim Wadhwa-Brown from Cisco Customer Experience to learn what encryption really accomplishes, where it leaves gaps, and when defenders need to take proactive measures.Whether you’re picturing classic codebreakers or the latest quantum-proof ciphers, this episode unpacks the essentials: what encryption and hashing actually mean, why key management is a make-or-break factor, and how even the best algorithms can fall short if the basics aren’t handled right.G7’s “Coordinating the Transition to Post-Quantum Cryptography in the Financial Sector” roadmap: https://home.treasury.gov/news/press-releases/sb0355

Get ready for a brand-new era of Talos Takes! In the first episode of the year, Amy Ciminnisi, Talos’ Content Manager and new podcast host, steps up to the mic with Joe Marshall to explore certifications, one of cybersecurity’s overwhelming (and sometimes most controversial) topics. We dive into the world of vendor-specific and vendor-agnostic certs, the value they can bring to your career, and the barriers people often face to getting certified.Whether you’re a newcomer facing the sea of choices and feeling some analysis paralysis or a seasoned pro plotting your next move, this episode may just motivate you to tackle your next certification with confidence.Cybersecurity certification roadmap: https://pauljerimy.com/security-certification-roadmap/

In this special, end-of-year episode (and Hazel’s final show as host) Talos Takes goes on a time-travel adventure: What would a defender from 2015 think of the cybersecurity realities of 2025? Joined by Talos teammates Pierre Cadieux, Alex Ryan, and Joe Marshall, we compare the threats, tools, and challenges of 2015 with those of 2025. The team recalls where they were in their careers a decade ago, then dives deep into how ransomware has evolved, how APTs and state sponsored attacks have shifted, and why identity has become the new battleground for attackers and defenders alike. They discuss the impact of AI on both sides of the security equation, share what they miss from “the good old days,” of 2015, and offer practical advice for defenders facing the challenges of 2026 and beyond.

What happens when your to-do list keeps growing but your budget doesn’t? Hazel is joined by three Cisco Talos Incident Response experts to talk about the reality many organizations face: rising threats, aging infrastructure, and fewer people to defend it all.From configuring what you already have, to open-source strategies, to the impact of cybersecurity layoffs, this episode is packed with practical guidance for securing your organization during an economic downturn.Resources mentioned:https://blog.talosintelligence.com/cybersecurity-on-a-budget-strategies-for-an-economic-downturn/https://blogs.cisco.com/news/doubling-down-on-resilient-infrastructurehttps://talosintelligence.com/incident_response

In this episode of Talos Takes Hazel sits down with Talos’ Bill Largent and Craig Jackson to discuss the latest Cisco Talos Incident Response Quarterly Trends Report (Q3 2025). From a wave of Toolshell events, to a rise in post-exploitation phishing, and the misuse of legitimate tools like Velociraptor, this quarter’s cases all point to a theme: attackers are getting very good at living off what’s already in your environment.

On this episode of Talos Takes, Hazel welcomes Cisco Duo experts Steven Leung and Tess Mishoe to bust the most common myths around passwordless security and multi-factor authentication (MFA). Discover why not all MFA is created equal, why passwordless doesn’t mean less security, and the most seamless way to adopt passwordless solutions. Plus, learn the truth about how passwordless may affect compliance and audits, and whether passwordless really is more vulnerable to phishing. 

Every October, Cybersecurity Awareness Month brings a wave of tips: update your software, enable MFA, use strong passwords. But what good is any of that if the people behind the defenses are feeling burned out?In this episode of Talos Takes, Hazel sits down with Joe Marshall for a candid, vulnerable conversation about the human cost of cybersecurity. Joe opens up about his experience during the VPNFilter campaign — months of secrecy, long hours, immense pressure, and the trauma it left behind. Hazel shares her own journey with burnout, and together they talk about how to recognise the warning signs.They close with practical steps: building a personal “incident response playbook” that includes boundaries, peer support, and self-care. Because at the end of the day, you can’t patch a system if you’re burned out. 

Imagine downloading a PDF Editor tool from the internet that works great…until nearly two months later, when it quietly steals your credentials. That’s the reality of “Tampered Chef,” a malvertising campaign that preyed on users searching for everyday software.In this episode, Nick Biasini explains how cybercriminals are investing in “malvertising”, why enterprises are prime targets, and why there are additional challenges when it comes to defending against time-delayed attacks.

How do you build and defend a network where attacks are not just expected-they’re part of the curriculum? In this episode, Hazel talks with Jessica Oppenheimer, Director of Security Operations at Cisco, about the ten years she’s spent in the Black Hat Network Operations Center (NOC).Explore the technical challenges of segmenting and monitoring a network designed for experimentation, live hacking, and hands-on training, including how malicious and benign behaviors are distinguished in real time. Jessica shares how the NOC leverages Cisco technologies like the new machine learning-powered SnortML engine to detect zero-days, outliers, and advanced attack patterns that traditional rule sets miss.Learn how automation, contextual analysis, and collaborative response drive decision-making in this high-stakes environment, and how those lessons now influence security at global events like the Olympics and the Super Bowl.For more details, check out the Cisco blog wrap detailing all our Black Hat NOC activity https://blogs.cisco.com/security/bhusa-2025-noc
