Year in Review special part 3: Identity and MFA attacks

Year in Review special part 1: vulnerabilities, email threats, and adversary tooling
Talos researchers Martin Lee and Thorsten Rosendahl join Hazel for the first of our dedicated episodes on the top findings from Talos' 2024 Year in Review. We discuss the vulnerabilities that attackers most targeted, how this compares with CISA's list, and how to protect network devices. Given how email lures are evolving, we spend some time chatting about how the current world news cycle may play into adversary's campaign cycles. And finally we touch on how to spot signs that your own sysadmin tools may be being used against you. For the full report, head to https://blog.talosintelligence.com/2024yearinreview/

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
