I'm at a security conference and sat in on an interesting talk. Not interesting as it was good, more interesting as in I can't believe what I was seeing. Let me explain.

Kudos to the @TrustedSec IR team effort for completing @OSINTDojo's OSINT challenge this week.

The image is a South Korean Internet cafe. There were 0 people in seats on 8/1, but that was not the last screenshot. On 8/10 there were 4 people. How did we find it? (1/X) We initially recognized it as a screen capture from a cam. The most logical place for that was shodan. But there are a lot of images on shodan. (side note, there are some creepy things people have cameras on...) (2/X)

Quick 5 minute on quickly analyzing Linux exes...even if you don't know how to do malware analysis. Hopefully this is helpful to someone.

Got a log4j hit on a Tomcat honeypot I set up. Used cyberchef and it decodes to download malware (1/8)

#dfir After dl'ing it on an analysis system (a mac), my first step is to run file to see what we are dealing with. I always run file - it saves steps and gives valuable info.

I've worked a lot of #ransomware incidents and I've found that most companies don't realize what the true cost of a ransomware incident is.

But isn't it just paying the ransom or restoring and you're done? Nope. Here are the (potential) costs (based on my experience): (1/X) Cost 1. Insurance

Wait, won't insurance help me recover money? Yep. But there's a little thing called a deductible. So, while this isn't a direct cost, it's still gonna cost you money. (2/X)
