Leveraging DHCP Weaknesses
DHCP is a accepted and advantageous LAN protocol. It is attenuate to appear beyond a networked device
today that doesn’t abutment it. Printers, IP phones, laptops, and routers can all access an IP
address dynamically application DHCP—and they generally do. DHCP has become a de facto
building block of abounding avant-garde LANs. Just like several agreement implementations covered
in this book, DHCP wasn’t congenital with aegis in mind. Hackers apperceive that and, naturally,
some accoutrement accept alike to booty advantage of DHCP’s weaknesses. As one advance tool
puts it:
The accepted appellation is Dynamic Host Configuration Protocol, but it should be accepted as the Domain Hijack
and Control Agreement as it is actively flawed.1
Denial of account (DoS), abode spoofing, and man-in-the-middle (MITM) attacks are on
