About six months ago, I was doing some forensics on a cracked Linux system belonging to a friend of mine. It had a rootkit installed, and a .history file showed that the rootkit had been transferred to the machine with rcp from the lp account on a host in China. I logged into the lp account with rlogin. It had ++ in .rhosts. It was a SunOS 5.5 system with no patches installed. The lastlog showed logins from dial-up and DSL or cable accounts from all over England, The Netherlands and the USA. It was obviously being used as a hacking base and a rootkit repository. There were several backdoors installed in the system, several setuid root shells lying around here and there, and a ++ .rhosts file for every system account. I guess China is an easy target to exploit in this way. General knowledge of systems security seems low, and most people, even intellectuals, lack foreign language skills. A complaint will get ignored because the responsible person doesn't understand the language it is written in, or even doesn't understand the technical and security implications of what is happening. All this makes me suspect the Chinese are victims in this matter, rather than perpetrators. In short: never attribute to malice that which can adequately be explained with stupidity. -- |-------Elías Halldór Ágústsson-----------http://this.is/bofh/-------| | Systems Administrator, Reykjavík, Iceland.
