Echo - Simple DNS data leak demonstration and proof
The echo.dnskv.com can be used to easily demonstrate how data leak over DNS works.
Send a DNS query with type to:
The server receives the data, and echoes it back as proof in the reply packet.
- Type: TXT
- Type: A
- Type: AAAA
If free key other than echo would have been used, the data would have been saved by the server and been ready for anyone else to retrieve from the server.
This address can be also used for data leak over DNS prevention testing.
The echo. queries aren't logged or saved in the database.
