Hello.
I was performing some system checks via some handy tools which I had used earlier as well. Those tools are :
- Lynis
- Rkhunter
- Arch Audit
- ClamAV/tk
There I found something unusual.
Rkhunter showed some interesting points :
Checking for suspicious (large) shared memory segments [ Warning ]

Should I be wary of these ?
