What kind of network are they using that lets them send forged source addresses? Also, a temporary solution in that case would be to use a blocklist of non-allocated ranges.
- the_mitsuhiko 11y agoBT is UDP and you can write whatever you want into a packet.
- voltagex_ 11y agoRight. Looks like I'll have to add some networking to my to-learn list. Thanks.
- banthar 11y agoAre you talking about changing source address in IP header? Most ISPs will drop such packets: https://tools.ietf.org/html/rfc3013#section-4.3 https://tools.ietf.org/html/rfc3013#section-4.3
- voltagex_ 11y agoThat's what I thought - but it turns out that not all ISPs behave well. https://defcon.org/images/defcon-22/dc-22-presentations/Graham-McMillan-Tentler/DEFCON-22-Graham-McMillan-Tentler-Masscaning-the-Internet.pdf https://defcon.org/images/defcon-22/dc-22-presentations/Grah... but the video is also very entertaining. This is applicable to the IPv4 internet but I'm sure someone will eventually come up with a way to do it for IPv6.
