It was a rainy holiday but I still enjoyed my stay in the Philippines last December 2018. My family visited the Mind Museum in BGC Taguig, which was just few minutes away from F1 Hotel where we stayed.
I always longed the fresh air and cool climate in Tagaytay, so we went there after celebrating the New Year. Our first stop was Paradizoo, a mini zoo where you can interact and feed various farm animals. They also have other attractions such as the butterfly garden and a honeybee farm.
We had Filipino lunch at Balay Dako and they have a spectacular view of Taal Lake and Volcano.
This helpful link describes the anatomy of a DHCP server spoofing attack. I also used a Layer 2 attack tool called Yersinia, which is included in Kali Linux distribution.
The ASA firewall/DHCP server currently displays only 1 host with the assigned IP address 192.168.10.43 (my iPhone).
To launch a DHCP Starvation (DoS) Attack, go to DHCP tab > Launch attack (gear icon) > choose sending DISCOVER packet > OK.
The DHCP table went full (42 Active Leases) in less than a minute.
To stop the DHCP Starvation attack, click List attacks > Stop

In my Cybersecurity lab, the Cisco
ASA5506-X act as the DHCP server for the wired inside hosts on the
192.168.1.0/24 subnet and for the wifi hosts on the
192.168.10.0/24.
Both DHCP
ranges has a maximum of 42 IP addresses that it could lease out:
- 192.168.1.10 - 192.168.1.50
- 192.168.10.10 - 192.168.10.50
The ASA firewall/DHCP server currently displays only 1 host with the assigned IP address 192.168.10.43 (my iPhone).
