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.

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.
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.

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.

Ransomware is 35 years old this month, which isn't exactly something to celebrate. But in any case, do join Hazel and special guest Martin Lee to discuss what happened in the very first ransomware incident in December 1989 and why IT "wasn't ready".
They then discuss how ransomware evolved to become the criminal entity it is today, which involves looking back on the likes of SamSam, Maze and the emergence of crypto currencies. Plus, learn why Martin says we shouldn't feel powerless in the face of ransomware.
Chetan Raghuprasad is our guest today as he breaks down the relatively new Interlock ransomware attack. Cisco Talos Incident Response recently observed this attacker conducting big-game hunting and double extortion attacks.
Chetan talks about the initial access tactics, deployment of the ransomware encryptor, and how Interlock communicates with its victims using their “Worldwide Secrets Blog”.

What happens when two sets of threat researchers from Talos and Splunk's SURGe team meet? Aside from some highly controversial opinions and omissions about the best horror movie, the team discuss what security trends are FUD, and what's actually fearful/ most challenging at the moment. Also, what is the security industry not aware of enough, and also too aware of? Plus some thoughts on cybersecurity awareness training and how we can do better.
This is a great conversation facilitated by SURGe's Mick Baccio, with Joe Marshall and Nick Biasini from Talos, and Tamara Chacon and Audra Streetman from SURGe.

The Talos IR Quarterly Trends Q3 2024 is out now! In this episode Hazel Burton, Craig Jackson and Bill Largent discuss three big themes: some new ransomware players, the 'Bring Your Own Vulnerable Driver' trend, and why password spray attacks are making a comeback.

Hazel Burton steps in as guest host this week to talk to Brad Garnett, the head of Cisco Talos Incident Response, and JK Lialias, the head of cybersecurity product marketing for Splunk. Brad and JK share two exciting in which Talos is being incorporated into Splunk now, and what that means for the ways we can keep users more secure. They also talk about what better visibility into attacker trends means for the end user and defenders.
James Nutland from Talos' Threat Intelligence team joins the show this week to talk to Jon about his report on the BlackByte ransomware group. They cover why this group is actually more active than we initially thought, and check on the general state of ransomware at this point in 2024.
