Patched a VMware environment
Installed critical security updates
VMware published a pretty large vCenter security advisory today, VMSA-2021-0020. This includes a number of nasty vulnerabilities, including one (CVE-2021-22005) bearing a CVSSv3 base score of 9.8: 

A malicious actor with network access to port 443 on vCenter Server may exploit this issue to execute code on vCenter Server by uploading a specially crafted file.

YIKES.

Anyway, I've started patching my vCenter environments. You probably should do yours too.
Learning about cybersecurity
Published an article
🐣 Starting a new series where I'm presenting how you can safely grab the malicious code and by using various techniques like decompiling and deobfuscation to see what it is doing. In this series, you are going to see different approaches and solutions that are used to bypass antivirus and other threat defenses, learn how to approach payloads and hopefully recognize common patterns that are reused by malicious actors.

❓ What do you think about it? What specific topics are you interested in?

I'm bridging the distance between practical applications and theoretical knowledge, by publishing detailed hacking challenges write-ups, participating in CTF events and presenting step-by-step guides.

I participated in this year's CSAW qualifying CTF. I didn't do much, but I succeeded at some binary exploitation, reversing some python, utilizing hashcat to crack some hashes and doing an easy web challenge. I also managed one of the harder web challenges - albeit after the competition ended. 
I greatly enjoy the CTF format that to me is like a bunch of bite-sized puzzles, forcing me to think about things I rarely get to think about 🤯
