I don't know who you are. But thank's for the sharing of thought, appreciate it. Most important new thing is this telnet scanner... That's hardly a major improvement over the existing Kaiten. . Oh, I agreed with you perfectly, and I didn't say majorly improved, but they added services bruter/scanner...

The getdents64 system call is available on 32 bit Linux, ARM, MIPS... etc... As it has nothing to do with the CPU architecture, but rather, the sizes of data the syscall can deal with. To be very honest, I missed deep checks on the above getdents* man(2) details during observation, as I just read t...

This is not exactly a f-- APT or anything, its effectively copypasta. It probably *is* some poor sods college assignment for a network security class or something that went a bit awry. Thank you for your post. I think you should see the post/blog report well, instead using some Fxxx words in our re...

Thanks, nice analysis. Did you manage to obtain a x64 sample mentioned on one of the screenshots from the article? I thought so too (main part x64 could be a nastier stuff..like rootkit etc) actually. Tried to seek everywhere for it, it's just not in there. Upon surveillance of the university activ...

A university kid in Shanghai, China made this malware in his "school project" and run a wide-test for it, he uploaded the sample for checking its FUD.. why a friend poke me for that. His purpose is definitely suspicious. I analyzed it in here: http://blog.malwaremustdie.org/2015/12/mmd-0047-2015-ssh...
