Have you ever wondered what it takes to put on a major event like a World Cup or the Olympics, and all the cybersecurity and threat intelligence that needs to be done beforehand? Today’s episode is all about that. Hazel is joined by one of our global Cisco Talos Incident Response leaders, Yuri Kramarz, who has helped some of the biggest events around the world take place securely.We chat about risk factors, focus areas such as endpoint protection, threat hunting and incident response, and what to do in the hours and minutes leading up to the event.Check out the document we mention - a full blueprint on how to protect major events:https://blog.talosintelligence.com/protecting-major-events-blueprint-october-2024-update/

Why attackers are using hidden text salting to evade email filters
In this episode Hazel chats with Omid Mirzaei, a security research lead in the email threat research team at Cisco Talos. Omid and several Talos teammates recently released a blog on hidden text salting (or poisoning) within emails and how attackers are increasingly using this technique to evade detection, confuse email scanners, and essentially try and get phishing emails to land in people’s inboxes. Hidden text salting is a simple yet effective technique for bypassing email parsers, confusing spam filters, and evading detection engines that rely on keywords. The idea is to include some characters into the HTML source of an email that are not visually recognizable.For more, head to the Talos blog

How to establish a threat intelligence program (Cisco Live EMEA preview)
It's an European takeover this week, as Hazel sits down with Talos EMEA threat researchers Martin Lee and Thorsten Rosendahl. They're heading to Cisco Live EMEA next week (February 9-14) to deliver a four hour session on how to establish a threat intelligence program. If you can't make it - here's a 15 minute version! Thorsten and Martin provide best practices for threat intelligence, the different flavors of it (tactical, operational, and strategic), and the significance of curiosity and learning from failures.If you haven't already, check out Martin's introductory course to threat intelligence in collaboration with Cisco’s Networking Academy. This course is free for all, and is intended to give an overview of the domain for someone without prior knowledge which can be used as a starting point for further study or employment.

Web shell frenzies, the first appearance of Interlock, and why hackers have the worst cybersecurity: IR Trends Q4 2024
Joe Marshall and Craig Jackson join Hazel to discuss the biggest takeaways from Cisco Talos Incident Response's latest Quarterly Trends report. This time the spotlight is on web shells and targeted web applications – both have seen large increases. There’s a brand new ransomware actor on the scene – we’ll talk about the new Interlock ransomware and how we’ve seen this group show up this quarter. Plus, Talos IR observed threat actors using remote tooling in 100% of ransomware incidents this quarter – that’s a significant uptick.

Exploring vulnerable Windows drivers
Hazel sits down with Vanja Svajcer from Talos' threat research team. Vanja is a prolific malware hunter and this time he's here to talk about vulnerable Windows drivers. We've been covering these drivers quite a bit on the Talos blog over the last year, and during our research we investigated classes of vulnerabilities typically exploited by threat actors as well as the payloads they typically deploy post-exploitation. The attacks in which attackers are deliberately installing known vulnerable drivers only to later exploit them is a technique referred to as Bring Your Own Vulnerable Driver (BYOVD). If you're curious about this topic and the recommendations our team has to help you address vulnerable drivers in your environment, then this episode is for you. The full research can be found at https://blog.talosintelligence.com/exploring-vulnerable-windows-drivers/
