Quite possibly. There are a myriad of resources on hacking |
| 7 |
modems[1]. Also, most modems support performance configurations |
| 8 |
via "S registers". Often, vendors leave access to the modem's |
| 9 |
"S registers" accessible and error on the side of ease of access. |
| 10 |
Others have brain_dead interfaces, just begging to be hacked. |
| 11 |
|
| 12 |
Then there are the wireless ports, usually configured to just "work" |
| 13 |
upon reboot with the widest possible range of open configs. Some |
| 14 |
"cable modem" ISPs allow you to purchase better quality hardware |
| 15 |
and use it, as long as they are given control over the mode. It's |
| 16 |
like the wild wild west, still lots of open range. |
| 17 |
|
| 18 |
|
| 19 |
Furthermore, modems are still a common, bountiful?, injection point |
| 20 |
for all sorts of nefarious activities, including governments not local |
| 21 |
to your nation. |

What we really need is a gentoo project to have a repository of |
| 25 |
gentoo based open source router (and transparent bridges) solutions. |
| 26 |
It's a ton of work for one person to stay on top of. Others will suggest |
| 27 |
some solutions like a shorewall fw behind your cable modem. Sorry for |
| 28 |
digressing off the dns specific hacking activity you have most likely |
| 29 |
stumbled upon. But if you fix that, and hackers like your node, they'll |
| 30 |
just migrate to other layers and parts of the stack..... |
| 31 |
|
| 32 |
On dns security issues, I'd speak with your local ISP in addition to |
| 33 |
discovering where your system(s) are resolving off of. Bad routing |
| 34 |
tables and routing instability are constant problems on the wider net. |
| 35 |
Your (ISP) router jocks may be understaffed, or just plain lazy..... |
| 36 |
|
| 37 |
There are a myriad of 'third party' solutions to quality/secure dns |
| 38 |
services, but, that is the responsibility of your ISP, usually. |
| 39 |
|
| 40 |
net-dns/bind-tools contains an excellent tool call "dig". |
| 41 |
Google for syntax examples...... |
