TEST QUESTION -
This system was recently patched following the exploitation of a vulnerability by an attacker to enable data exfiltration.
Despite the vulnerability being patched, it is likely that a malicious TCP service is still running and the adversary has achieved persistence by creating a systemd service.
Examples of commands to use:
kill, killall
lsof
man, --help (use for assistance)
netstat (useful flags: a, n, g, u)
ps (useful flag: a)
systemctl (to control systemd)
Please note: the list of commands shown above is not exhaustive. All native commands are available.
INSTRUSTIONS -
Using the following credentials:
Username: labXXXadmin -
Password: XXXyyYzz!
Investigate to identify indicators of compromise and then remediate them. You will need to make at least two changes:
1. End the compromised process that is using a malicious TCP service.
2. Remove the malicious persistence agent by disabling the service's ability to start on boot.
















 

Suggested Answer: See explanation below.



Find the malicious service and use ג€Killallג€ switch command to end the process.
