Folks,

A friend of mine was reviewing her daily LogWatch reports and noted that there was a strange entry. The file was "/tmp/.c" and the full entry was

  User root:
     /tmp/.c 203.130.232.110 62282: 1 Time(s)

That seems like an address in Indonesia.

When she ran "strings" against it, it had the following strings

/lib/ld-linux.so.2
__gmon_start__
libc.so.6
strcpy
connect
getenv
__strtol_internal
execve
dup2
sleep
socket
bzero
__deregister_frame_info
wait
fork
memset
gethostbyname
exit
_IO_stdin_used
__libc_start_main
setuid
__register_frame_info
close
GLIBC_2.0
PTRh@
8(t1@8(t,@8(t'@
8(t1@8(t,@8(t'@
/usr/sbin/named
SHELL
/bin/sh

Anyone have any idea what got on her system? She is running Red Hat 8 and is fully patched as can be. She also ran "chkrootkit" - the latest build recompiled on anther system - and it didn't find any rootkits.

Thanks!

Cheers,
Mike
