One of the most frequent questions I'm asked is "how do you stay up to date on malware stuff?" Okay, here is a pro tip: 1. Google OTX AlienVault 2. Make account 3. Look at latest 4. Scroll until you find posts from a guy named Petr something-something (has numbers in his name). 4. Follow his account He monitors all the big malware places and shares the URL, hashes, etc. from malware vendors. I've been following this random ass dude for years and getting updates on everything. I have no idea who he is. I don't know where he's from. All I know is his setup is absolute fire and he keeps you up to date on literally everything malware related 24/7 365. He also has stuff from vendors in China, Russia, Japan, etc. Every morning I log into OTX and check up on my boy Petr to see what fire he's bringing me. I love him.
