Recently we found a suspicious shellcode running in the memory of a system process. We decided to investigate how the shellcode was initially placed into the process and where on the infected system the threat was hidden.

We named this #malware #Minas 👉 https://kas.pr/fn5y

This is interesting reading regarding the .zip TLD. However, it's of near zero consequence to phishing attacks, read it first then I'll explain: https://medium.com/@bobbyrsec/the-dangers-of-googles-zip-tld-5e1e675e59a5

Ppl that run an honeypot: what hosting company are you using? What is your fav software?
Hi all,
I’d like to run an honeypot in the hope to collect some current malware samples. If you are an honeypot admin, then I have some questions for you:

1) what software are you running? And why?
2) what is the hosting company that is hosting your honeypot/honeypots?
3) How much do you pay every month?
4) what software would you suggest for a cheap/low end VPS?
5) after how much hours/days have you collected the 1st binary sample in your honeypot?

I have done some research and I found an incredible AIO solution called T-POT. It is a collection of the most used honeypots (cowrie, dionaea etc.) but it requires 8+ GB of ram and 150GB of HDD space… so it will not be cheap to host this 😕

Thanks a lot!

I run a custom HTTP honeypot at the edge of my home network and on a cheapy VPS. I'm able to find command injection attempts in payload and headers which usually yield Mirai and Mozi samples.

Overall, I collect the request data and store it in a MySQL table for aggregating stats.

T-pot, set a few malware files in the server as well

I run 3 honeypots on EC2/Lightsail instances at AWS. I am using mainly Snort/Suricata to detect attacks against the devices - not so much a 'honeypot' but I am in the process of standing up more low-interaction true honeypots on the platform. Lightsail can do fixed cost of like $5/$10/$20 etc price points, overall price with a syslog server to aggregate everything is like $30-40 per month or something, maybe a little less. Hard to tell since I am running lots of other things on AWS.

T-POT is extreme end of honeypots..not worth it for me.
