I have a few false positive scans on my rkhunter. However I did a scan today and these results do kinda worry me, I have 8 warnings now. I will post the warnings that Im not sure about.
/usr/sbin/runlevel [ Warning
/usr/bin/sudo [ Warning
/usr/bin/systemd [ Warning ]
/usr/bin/systemctl [ Warning ]
/usr/lib/systemd/systemd [ Warning ]
These are the new warnings that showed up. I looked into the log and found this.

I really need help on this to find out if this is a false positive or not. Systemd does concern me along with the other warnings. Thanks.
Update
A user told me to look at recent updates and I remember I did do some updates linux wanted me to do in the past 2 days and I found in history of updates some lines libsystemd0, systemd-coredump, libnss-systemd,systemd, libpam-systemd and other updates. Seeing all these updates involving systemd is a sure sign of false positives. I need to look at my update history more after these scans. Im gonna look at the man page in rkhunter to restore every warning to OK. Its solved.
