One mighty fine-looking report

Welcome to this week’s edition of the Threat Source newsletter. 

They say art is subjective, but have you ever seen a well-formatted bar chart? Van Gogh had Starry Night, but Talos’ 2024 Year in Review (available now!) has color-coded data with perfect labels. True beauty. 

If you haven’t yet had a chance to fully digest this gorgeous report (massive shout-out to our creative team), here are some links. Clicking on them may not change your life, but what if it does? Only one way to find out: 

Our Year in Review landing page houses all our Year in Review content, from videos to podcasts and topic summaries. There’s more content coming out every week this month. Oh, you can also download the report itself here, which is useful. 

Here’s a two-minute animated overview. Watch those bad boy bar charts come to life. 

The TTP: Year in Review Special (Part 1) is inspired by The Last of Us in more ways than you might think. We have a two-part video interview with the report’s authors, featuring me calling cybercriminals “cheeky f*****s.” Part 2 is coming out tomorrow, April 4th. 

This Beers with Talos B team episode genuinely caused someone to direct message me, citing their spouse’s concerns about their laughter levels when listening (“Are you okay?”). 

A couple of the report’s top findings: 

  • Ransomware actors overwhelmingly leveraged valid accounts for initial access in 2024, with this tactic appearing in almost 70 percent of Cisco Talos Incident Response cases. 
  • Operators endeavored to disable targets’ security solutions in most of the Talos IR cases we observed, almost always succeeding. 
  • Some of the top-targeted network vulnerabilities affect end-of-life (EOL) devices and therefore have no available patches, despite still being actively targeted by threat actors.

The one big thing 

Cisco Talos is actively tracking an ongoing campaign targeting users in Ukraine with malicious LNK files, which run a PowerShell downloader. The file names use Russian words related to the movement of troops in Ukraine as a lure. Talos assesses with medium confidence that this activity is associated with the Gamaredon threat actor group. 

Why do I care? 

The invasion of Ukraine is a common theme used by the Gamaredon group in their phishing campaigns and this campaign continues the use of this technique. The actor distributes LNK files compressed inside ZIP archives, usually disguising the file as an Office document and using names that are related to the invasion. 

So now what? 

Ways our customers can detect and block this threat are listed in this dedicated blog post.
