Hey guys, I saw this in my VPS when checking history:
1 chmod +x /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
2 cat /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
3 vi /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
here is the content of the script:
# cat /usr/lib/virt-sysprep/scripts/0001-swapoff--dev-vda2-mkswap--dev-vda2-swapon--dev-vda2-resize2f
swapoff /dev/vda2;mkswap /dev/vda2;swapon /dev/vda2;resize2fs /dev/vda1;yum -y update;systemctl disable guestfs-firstboot;reboot
This is a new server I provisioned on my VPS in racknerd. The command looks safe, but I’m wondering if these commands were executed on its own? Or someone has logged in to my VPS? This is also not normal, isn’t it?
EDIT:
confirmed, commands are still in history after reinstalling OS. As others have said, maybe the image builder ran commands and forgot to clear history
I’d say they made the image, started it, did minor adjustments and didn’t delete the command history before stopping it and starting to deploy the image.
Looks harmless, although a tad sloppy.
