Hello, I'm fine :)

Sorry, I forgot to link of the post I was talking to, so here it is: http://www.kernelmode.info/forum/viewto ... 505#p23989

I tried to make sigfiles to detect glibc's functions linked with that malware but I didn't find the proper glibc version used :(

Hello,

The project file list you give is just glibc's stuff as the nginx malware is statically-linked with it, so it's useless for detection unfortunately

The key changes depending of the version of darkcomet.

For a darkcomet 4, the key will be #KCMDDC4#-890, for darkcomet 5, it's #KCMDDC5#-890 and for darkcomet >= 5.1, the key becomes #KCMDDC51#-890

As promised, I wrote an article about this sample (which is really a andromeda 2.07 sample) which you can read here: http://aassfxxx.infos.st/article22/andromeda-2-07-analysis (feel free to ask me question here on in comments about this article ;) ). In this version, nothing really new, just some fu...

That's an old or different build of Andromeda, variant "I". In this thread mostly attached "F" variant. Analyze code, not how and where it connects. Usual Andromeda encrypted strings related to AntiVM/SandboxIE. Ќ…ЊюяяPяuґяUр…А…pяяяяuґяUмhdll hdll.hsbie‹ДPяUьѓД…А…© З…|юяя j h.dllhpi32hadva‹ДPяUи‰EА...

I think pcap traffic is a little bit useless for andromeda, since the bot traffic is encrypted (with the bot key). The bot key is stored with url list, and I wrote some tools (in python 2) which allow to extract andromeda config from an unpacked sample and query c&c co get stuff dropped by andromeda...

Btw, I saw the comment of unixfreakjp on my blog, so I'll answer the two questions asked (I have to create another post since I can't edit my previous post) : 1. What was the "weird string" you talk about? The string I found was BLC.bdR3S% 1!rA2l"h=EDWOwf6oU,s0Nec8muMk4Ttp-IiaQP',27h,';)v(xF , used ...

@unixfreakjp: first, I think the "Security" key you found won't help to decode data because it's just windows service manager crap (the malware creates its service of not installer, and then launches the service with the command round above. Then, for the ugly string I found, it doesn't seem to be a...
