What do you want? It's just a basic rootkit that hooks some specific
entries inside the sysent table. It can be detected by checking if a
device /dev/turtle2dev exists or by sending an ICMP echo request with
a payload starting with a double '_' and if rootkit is loaded no reply
will be returned.
[root@clem1 ~/koda/Turtle2/module]# hping -c 1 -n 127.0.0.1 -e "__foo" -1
HPING 127.0.0.1 (lo0 127.0.0.1): icmp mode set, 28 headers + 5 data bytes
[main] memlockall(): No such file or directory
Warning: can't disable memory paging!
--- 127.0.0.1 hping statistic ---
1 packets tramitted, 0 packets received, 100% packet loss
These tricks can be implemented inside rkhunter or/and chkrootkit.
Best regards,
