How Attackers Use Your Own Tools Against You (IR trends Q3 2025) Nov 13, 2025

Show notes

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.

Passwordless Security: Debunking the Biggest Myths Oct 24, 2025

Show notes

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.

You Can't Patch Burnout: When Cybersecurity Takes a Toll Oct 02, 2025

Show notes

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.

Tampered Chef: When Malvertising Serves Up Infostealers Sep 18, 2025

Show notes

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.

Inside the Black Hat NOC: Lessons in Securing One of the Wildest Networks Sep 03, 2025

Show notes

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.

Breaking Down Chaos: Tactics and Origins of a New RaaS Operation Aug 01, 2025

Show notes

Hazel is joined by threat intelligence researcher James Nutland to discuss Cisco Talos’ latest findings on the newly emerged Chaos ransomware group. Based on real-world incident response engagements, James breaks down Chaos’ fast, multi-threaded encryption, their use of social engineering and remote access tools like Quick Assist, and the group’s likely connections to former BlackSuit operators. James also shares what defenders should be watching for and how to stay ahead of evolving ransomware tactics.

Why Attackers Love Your Remote Access Tools Jul 17, 2025

Show notes

Attackers are increasingly abusing the same remote access tools that IT teams rely on every day. In this episode, Hazel sits down with Talos security researcher Pierre Cadieux to unpack why these legitimate tools have become such an effective tactic for adversaries.

Pierre explains how the flexibility, legitimacy, and built-in capabilities of remote access management tools make them ideal for attackers who want to stay under the radar. They discuss trends Talos Incident Response is seeing in the field, examples of commonly abused tools, and the challenges defenders face when trying to detect misuse.

You'll also hear practical advice on what defenders and IT teams can do today to better secure their environments — and what the rise of remote access management tool abuse tells us about attacker behavior and the current state of cybercrime.

Teaching LLMs to spot malicious PowerShell scripts Jun 26, 2025

Show notes

Hazel welcomes back Ryan Fetterman from the SURGe team to explore his new research on how large language models (LLMs) can assist those who work in security operations centers to identify malicious PowerShell scripts. From teaching LLMs through examples, to using retrieval-augmented generation and fine-tuning specialized models, Ryan walks us through three distinct approaches, with surprising performance gains.

How cybercriminals are camouflaging threats as fake AI tool installers Jun 05, 2025

Show notes

Chetan Raghuprasad joins Hazel to discuss his threat hunting research into fake AI tool installers, which criminals are using to distribute ransomware, RATS, stealers and other destructive malware. He discusses the attack chain of three different campaigns, including one which even tries to justify its ransom as "humanitarian aid."

Inside the attack chain: A new methodology for tracking compartmentalized threats May 22, 2025

Show notes

Edmund Brumaghin joins Hazel to discuss how threat actors (including state sponsored attackers), are increasingly compartmentalizing their attacks i.e they're bringing in specialist skillsets from other groups to handle different aspects of the attack chain. Edmund discusses why this is happening, and the challenges this poses for defenders when it comes to attribution and reporting. He then discusses several solutions which seek to evolve traditional threat modelling, and help provide clarity to defenders.
