    Talos Takes Ep. #63: Shield your eyes from the Solarmarker

    Andrew Windsor from our malware research team joins the show for the first time to talk about Solarmarker. This is a campaign Andrew’s followed for a while that recently added new modules that make it particularly dangerous. The attackers behind Solarmarker could basically use this threat to drop whatever they want. At least for now, they’re sticking to information-stealing. But could it ever get worse than that?

    Talos Takes Ep. #62: There's still plenty of mileage left in BEC

    Business email compromise may seem like last decade’s threat, but it’s still just as prevalent as ever. A recent FBI report found that it cost users more than $1 billion in 2020, and attackers are now capitalizing on everything from PlayStation 5 sales to the COVID-19 pandemic to still scam people. On this week’s Talos Takes, Nick Biasini recaps his recent research into BEC and discusses why there are some reasons why this threat may never go away (hint: users).

    Talos Takes Ep. #61: Why does SideCopy seem so familiar?

    The last time Jon had Asheer Malhotra from Talos Outreach on the show, they covered the Transparent Tribe APT. Asheer joins the show again this week to talk about another threat actor that is very similar to Transparent Tribe, but is just a tad different. Asheer recently co-authored a research paper on the aptly named SideCopy actor, which borrows many TTPs from their fellow actors, including Transparent Tribe. This episode, we’ll talk about SideCopy’s methods, why they may be borrowing so much from those around them and where they could go from here.

    Talos Takes Ep. #60 (XL Edition): Kaseya emergency show

    In this special “XL edition” of Talos Takes, we’re bringing you the audio version of our live stream this week discussing the Kaseya supply chain attack. Nick Biasini from Talos Outreach went live with Hazel Burton, a Cisco product marketing manager, to discuss what transpired over the long Fourth of July weekend. 
    Nick discussed the Kaseya exploit leveraged in this campaign, plus the follow-on ransomware attacks. This is the best place to get the tl;dr on what happened, what you need to be doing now, and what Cisco Secure solutions can keep you protected.

    Talos Takes Ep. #59: A deep dive into vulnerabilities in a home security station

    We’ve spent many minutes (that’s the point of the podcast, after all) discussing internet-of-things devices on this podcast. As consumers start having more “smart” devices connected to their home network, they may want an easy solution to keeping those devices safe. But what if that device gets owned?

    Carl Hurd of our vulnerability research team recently discovered several vulnerabilities in Trend Micro’s Home Network Security Station. He joins the show for the first time to talk about his research, the pros and cons of these all-in-one home network security devices, and how an attacker could exploit these issues to spy on your devices.

    Talos Takes Ep. #58: It's time to get serious about protecting critical infrastructure

    With major cyber attacks in recent years against major U.S. critical infrastructure suppliers like Norsk Hydro and Colonial Pipeline, we’re in a new world of CI cybersecurity. New threats require new approaches to defense. And in the U.S., this is likely going to include partnerships between those who manage critical infrastructure, government and the private cybersecurity sector.

    Talos recently outlined what this may look like in America. One of the authors of that post, Joe Marshall, joins Jon Munshaw this week on Talos Takes to talk about public-private partnerships to defend critical infrastructure.

    Talos Takes Ep. #57: What's in it for both sides of the ransomware-as-a-service model?

    How much is ransomware-as-a-service like a McDonald’s franchise? More similar than you’d think! The RaaS model has entered the mainstream over the past few months with groups such as DarkSide attacking the Colonial Pipeline.

    In these transactions, what’s in it for the original ransomware creator? And what do the operators themselves get out of it? Nick Biasini joins Jon Munshaw this week to talk about this business model, what it means for the rise in ransomware attacks, and how you can stay protected.

    Talos Takes Ep. #56: The first security steps when returning to the office

    We started out the COVID-19 pandemic by thinking we’d be away from the office for a month — maybe two. More than 12 months later, we’re still here, working from home (at least part-time).

    But some businesses are starting to reopen now and welcoming workers back into the office. After so much time working out of the office, what should security professionals do once they get back? In this week’s episode, Beers with Talos’ own Craig Williams joins the show to talk about triple-checking for patches, changing passwords and more. Plus, how should you handle the new hybrid worker?

    Talos Takes Ep. #55: What's next for Transparent Tribe?

    Asheer Malhotra from Talos Outreach has followed Transparent Tribe for years now. This APT has been all over the place using all sorts of trojans. So where my they go next? Asheer joins Talos Takes this week to discuss the malware this group deploys and how they use typo-squatted domains to lure victims in.

    Talos Takes Ep. #54: Incident response is really just the friends we made along the way

    Welcome to the unofficial incident response week at Talos! As part of the RSA Conference, we’ve released two new case studies detailing some malware cases Cisco Talos Incident Response helped resolve. Brad Garnett, this week’s guest, also released a new blog post where he wrote about why incident response is “the ultimate team sport.” Brad joins host Jon Munshaw this week to take a deeper dive into one of these engagements, in which an attacker tried to use Cobalt Strike to infect a target with ransomware (hint: this would have been really bad!) Brad talks about how the strong personal relationships CTIR built with the customer in question set everyone up for success.
