Cisco Talos has recently written about malware families that go open-source, sometimes of their own volition, and sometimes because of leaks . In the case of SapphireStealer, we still don't really know why someone posted this malware to GitHub, but now that it's out there, we can't put it back in a box. Edmund Brumaghin, who assisted with Talos' research and blog post on SapphireStealer , joins Talos Takes this week to discuss this information-stealer. Edmund talks about the goals that someone h...

Everything about the modern workplace is different now from the start of the COVID-19 pandemic. Many companies are embracing the remote work lifestyle, while others are stuck in a hybrid model or pushing employees to come back to the office. With that in mind, we felt like it was a good time to check in on the incident response process for companies who have to deal with working remotely and those who prefer to conduct business in person. Yuri Kramarz and Gergana Karadzhova-Dangela from Cisco Ta...

The stereotypical "hacker" who looks to do good in the world probably involves a Guy Fawkes mask and black hoodie. But hacktivism has become much more than that, especially since Russia invaded Ukraine. On the heels of a newly released overview on hacktivism , Lexi DiScola from the Talos Threat Intelligence and Interdiction team joins Talos Takes this week to discuss these actors. While not just anyone is likely a target for hacktivists, Talos has seen groups become more brazen and start looking...

When Martin Lee first told Jon about ISO 27001 and 27002 , Jon had to immediately Google whatever this combination of letters and numbers meant. Turns out there are international standards for cybersecurity, just like they have for selling lightbulbs and installing electrical outlets — who knew? Martin recently wrote about these standards for the Talos blog , outlining a list of recommendations for any organization looking to build a threat intelligence program from the ground up. Jon interviewe...

We decided to have a web navigation extravaganza this week! Guilherme Venere and Jaeson Schultz from Talos Outreach have both long been researching the ways in which bad actors try to damage users' inherent trust in the internet . Most internet users interact with the web by typing in a URL or domain name into their web browser (i.e., google.com) expecting that will take them to the right place. But attackers have found various ways to mess with that series of handshakes that must take place. Gu...

Cisco Talos Incident Response recently discovered an uptick in malicious actors compromising vendor and third-party accounts to sneak into targeted networks. Many enterprises have vendor and contractor accounts that need to access their network for a variety of things — IT support, cybersecurity, etc. — but these accounts are often monitored less than those belonging to full-time employees. Craig Jackson, who recently co-authored a blog post on this threat, joins Talos Takes this week to talk ab...

We're joined this week by Chetan Raghuprasad to discuss a new botnet he recently discovered and researched. Horabot can completely hijack a target's Outlook mailbox to steal their contact list and then send even more spam to targets. It's the perfect business email compromise tool for attackers that comes with a side of banking trojan. Chetan talks to Jon about this malware family's abilities, where it came from and what the actors behind it are hoping to achieve. For more, read Chetan's full bl...

Despite governments' best efforts, spyware is still running rampant on the threat landscape. These types of tracking malware are used to target high-profile individuals like politicians, activists, journalists and more — and even sometimes for jealous exes to track their former partners. Asheer Malhotra, who recently dissected the Predator spyware, joins Talos Takes this week to talk about Predator and its associated tool, Alien. Asheer shares new technical details about this spyware and discuss...

Tiago Pereira from Talos Outreach joins the show this week to talk about his recent discovery of a new phishing-as-a-service tool called "Greatness." Since everything else is "as-a-service" nowadays, it's only fitting that attackers have figured out how to monetize easy phishing tools, too. Tiago discusses what makes Greatness unique, why it's going after business targets specifically, and why it creates such convincing fake Office 365 login pages....

With another major supply chain attack recently making headlines, we felt like it was a good time to refresh our advice on how to prepare for these types of cyber attacks. Adversaries are increasingly relying on users' inherent trust of the software running on their networks and devices to deliver hijacked, malicious updates that are actually malware. Craig Jackson, a senior Cisco Talos incident responder, joins the show to provide some advice on how organizations can prep for the next major sup...

It's been just over a year since Talos formed our Ukraine-focused task force. After Russia's invasion of Ukraine, many of our teammates sprung into action to protect critical infrastructure and networks there — not to mention the Talos employees who literally had to fight back to protect their home country. In this week's episode of Talos Takes, J.J. Cummings, one of the lead organizers of this task force, joins the show to discuss the group's ongoing work. J.J. talks about where the situation i...

Public perception is such that it's assumed we just get more spam in the U.S. during two major times of the year — Tax Season and Black Friday.

In this episode of Talos Takes I am joined by security researcher Guilherme Venere to discuss their recent research on LNK files. The usage of these files by malicious actors has exploded over the last six months as actors look to move away from macro based initial infection vectors. LNK files do have unique metadata attributes to allows for useful actor and threat tracking capabilities. We'll dig deeper on LNK files as well as the metadata you can leverage. For full details check out the blog a...
