🔗 LazyAdmin
Task 1 - Deploy the machine
🎯 Target IP: 10.10.129.248
Create a directory for machine on the Desktop and a directory containing the scans with nmap.
Task 2 - Reconnaissance
Copy su
echo "10.10.129.248 lazyadmin.thm" >> /etc/hosts
mkdir thm/lazyadmin.thm
cd thm/lazyadmin.thm
# At the end of the room
# To clean up the last line from the /etc/hosts file
sed -i '$ d' /etc/hosts I prefer to start recon by pinging the target, this allows us to check connectivity and get OS info.
Copy ping -c 3 lazyadmin.thm
PING lazyadmin.thm (10.10.129.248) 56( 84 ) bytes of data.
64 bytes from lazyadmin.thm (10.10.129.248): icmp_seq = 1 ttl = 63 time = 448 ms
64 bytes from lazyadmin.thm (10.10.129.248): icmp_seq = 2 ttl = 63 time = 658 ms
64 bytes from lazyadmin.thm (10.10.129.248): icmp_seq = 3 ttl = 63 time = 141 ms Sending these three ICMP packets, we see that the Time To Live (TTL) is ~64 secs. this indicates that the target is a *nix system (probably Linux), while Windows systems usually have a TTL of 128 secs.

Task 3 - What is the user flag?
We can strat to explore http://lazyadmin.thm (port 80)
In the page source code we don't found nothing of interisting, the good route is to explore website hidden pathes using gobuster:
