037. The Easiest Way to Detect a macOS Stealer

Hello everyone! What do you know about macOS stealers? Looks like one can buy it on underground resources. And yes, we're seeing it in-the-wild more and more often!


But we are interested in detection opportunities, of course! Let's look at a report published by Unit42. There's an overview of three stealers: Atomic Stealer, Poseidon Stealer and Cthulhu Stealer. If we look through the report, we can see a very distinct feature: all of them abuse AppleScript to obtain the victims' password!

So, what to look for? Look for osascript executions with display dialog and password in the command line! That's it! That easy!

See you tomorrow!

Hello everyone! Everybody loves free courses, right? Have you missed a free course on Google Threat Intelligence ? If the answer is "Yes", it's your chance to check it!  I like this course as it not only overviews the capabilities of Google Threat Intelligence as a product, but also covers various threat intelligence use cases, for example, how to empower incident response and forensic investigations or how to use it for adversary hunting and tracking. I've already got my completion badge: What about you? See you tomorrow!

001. The Zeltser Challenge

Image
Hello everyone! Happy New Year! New year - new challenges! So, a few weeks ago David Cowen reminded me about the Zeltser challenge. What's the point? You must blog every day for a year to push yourself to research and write. Sound cool, right? Dave suggested to start the challenge with him on 1/1/25, and that's why you are reading this post! So, what am I going to share here? I'm a big fan of intelligence-led approach to cyber defense, so every day we'll look at this or that technique (or sub-technique) leveraged by real adversaries, so we can learn more about our enemies.  We'll look both at public reporting and private findings by BI.ZONE Threat Intelligence team. Stay tuned, and see you tomorrow!

012. They Want to Know Everything About Your System!

Hello everyone! Today we'll look at reconnaissance techniques leveraged by Secret Blizzard (also known as Turla) as seen in the report by Microsoft Threat Intelligence.  In this campaign Secret Blizzard used the Amadey bot to download its own backdoors to specifically selected target devices associated with the Ukrainian military. So, one of the batch scripts leveraged by adversary invoked lots of reconnaissance commands. Let's look at each of them: ver - to collect information about OS version; systeminfo - to collect compromised system information; ipconfig /all - to collect the full TCP/IP configuration for all adapters; ipconfig /displaydns - to collect the contents of the DNS client resolver cache; route print - to collect the entries in the local IP routing table; arp -a - to collect information on current arp cache tables for all interfaces; netstat -a -n - to collect information on active network connections; net share - to collect information on ...
