Talos Takes

Chetan Raghuprasad from the Talos Outreach team joins Talos Takes this week to talk to Jon about the GhostSec threat actor that he and a few colleagues wrote about for the Talos blog. GhostSec has teamed up with another ransomware group to carry out double extortion attacks all over the globe, with increasing frequency over the past year. They discuss what's unique about this particular RaaS model, where GhostSec came from, and the benefits of going in on a team-up. 

Now more than ever, adversaries are logging in, not breaking in. They're stealing legitimate user credentials to hide undetected on a targeted network after acquiring said credentials in a variety of ways. Hazel Burton joins Jon Munshaw this week to discuss identity attacks, recommendations for avoiding them, and how QR code phishing plays into these tactics. 

Gergana Karadzhova-Dangela and Thorsten Rosendahl, our resident experts on all things European Union cybersecurity law, join the show this week to talk about the impending NIS2 regulations. Don't worry, you've still got plenty of time to work on them, but this is a good place to get started even if you've never seen the phrase "NIS2" before. Find more of their writing on NIS2 here and here. 

Reposted from the Cisco Security Stories feed: Meet Jeremy Maxwell, CISO of Veradigm, a healthcare IT company. Jeremy discusses how his organization proactively prepares for cybersecurity incidents within a highly regulated industry.

Chris Neal from Talos Outreach joins the show today to talk about his research into the ways adversaries are using malicious drivers on Windows to spread malware. He recently launched a new series on the Talos blog about the basics of drivers and how security researchers can reverse engineer them to learn more about attacker TTPs and develop new detection content. Chris discusses when he first spotted this type of attack, what advantages it presents for the attacker and the other aspects of the research he plans to dive into.

This week, we're bringing you the audio version of our recent Talos IR On Air video. Several Talos incident responders got together to recap the top threats and attacker trends of Q4 2023, as outlined in our full Quarterly Trends Report. Hear about why ransomware was up for the first time the entire year, and which sectors were being targeted most often. 

We're talking about vulnerabilities this week with Jerry Gamblin from Cisco Vulnerability Management. Jerry joins the show to talk about the release of CVSS 4.0 this year — the newest method the security community will use to score the severity of certain vulnerabilities. Jerry discusses what makes this scoring system different from previous iterations if it changes how he views the term "severe" and how that fits into Cisco's overall vulnerability management processes. 

In this special edition of the show, we're bringing you the audio version of our Year in Review livestream. Recorded at the end of December, this stream included Hazel Burton, Nick Biasini and Laurie Varner from Cisco Talos Incident Response recapping the year that was in cybersecurity. They covered the highlights of our 2023 Year in Review report, their personal takeaways from the past year, and trends to watch for heading into the new year.

We're back from holiday break with the first new Talos Takes episode of 2024! We're continuing our dive into Talos' Year in Review report with Lexi DiSchola, one of the many researchers who helped put this report together. She discusses why we believe the telecommunications sector was the most-targeted industry in 2023, advice for companies in that space, and other popular targets for attackers. 

Jon apologizes for how he sounds in this episode, he was having mic troubles we discovered only during post-production. But outside of that, we continue the series of episodes recapping 2023 with our Year in Review report. This week, Aliza Johnson from the Talos Threat Intelligence & Interdiction team comes on the show to talk about data theft extortion. She shares why her team saw such a spike in this type of activity in 2023, what can be done to stop it, and which ransomware actors are pivoting to this tactic. 

To celebrate the launch of our 2023 Year in Review report, we're doing a series of episodes highlighting several of our key takeaways from the past year. First up, we have David Liebenberg from our Threat Intelligence team to discuss Chinese state-sponsored actors. This is an area David's been studying for many years now and actively researches. He'll discuss the latest Chinese APTs to step onto the scene and trends he's seeing from that area of the world. 

Joe Marshall, a central figure in the story of how Cisco Talos and other teams within Cisco worked together to protect the Ukrainian power grid, joins the show this week. He recaps a recent CNN story highlighting the new piece of equipment he and a group of volunteers worked on together to ensure the clocks that power the Ukrainian electric grid can withstand GPS disruption in the face of Russian cyber attacks and kinetic warfare. 

Guilherme Venere from Talos Outreach joins the show this week to talk about his research into the 8Base threat actor and its use of a variant of the Phobos ransomware. He recently published several works on the many variants of Phobos that exist in the wild, and why 8Base has been so successful using it for years now. 

Tiago Pereira from Talos Outreach joins the program this week to talk about his research into the different types of scams that appear in the online game "Roblox." Many underage users are at risk of being targeted by malicious users looking to steal their money, in-game items or even install malware on their devices. 

This week is a special edition of Talos Takes. We have the audio version of Talos Incident Response's recent On Air stream, where they discussed the top attacker trends they're seeing in the field. Talos' incident responders discuss the malware they're seeing most often in infections, how attackers are shifting their tactics, and what other defenders can learn from these findings. 

Jerry Gamblin from Cisco Kenna joins this week's episode to talk about all things patching. If you're the average user, you probably don't think about patching much because many of them happen automatically in the background. However many admins and users can unknowingly fall behind when it comes to protecting themselves against the latest vulnerabilities. 

Everyone is tired of getting spam emails at this point, and it can feel exhausting always to click that "report spam" button just to get another phony email a few hours later. But we're here to assure you that reporting and filtering spam really does help in the long run! Nick Biasini joins the show this week to discuss all things spam for Cybersecurity Awareness Month. 

To continue our Cybersecurity Awareness Month series, Harpreet Singh from Talos Incident Response joins Jon to talk about password managers. They discuss the upside of using a third-party service like 1Password or LastPass, the potential dangers of using built-in browser password managers like Google Chrome and Safari, and other good password hygiene advice. 

All of October, we'll be covering broad security-related topics for Cybersecurity Awareness Month. First up, we address the basics of implementing MFA in any environment, why any type of MFA is better than no MFA, the pitfalls of certain types of authentication, and whether going passwordless is the future. 

Hazel Burton takes over as guest host for this episode as she talks to Nate Pors from Cisco Talos Incident Response. Nate was part of Talos IR's team that helped Veradigm, a healthcare technology company, prevent a Qakbot ransomware attack. Nate and his team recently wrote about this experience for the Talos blog, and Veradigm's CISO even joined the Cisco Security Stories podcast recently to discuss his company's relationship with Talos IR. Nate discusses how his team's pre-existing relationship with Veradigm helped them respond quickly and effectively. If you've ever wanted to hear a play-by-play of a security event, this is your chance.
