[AusNOG] FYI : Attackers are accessing routers running on the border gateway protocol (BGP) and injecting additional hops

[Beeson, Ayden]

I'd assume it boils down to one of three things:

1. A lack of training or understanding of the concept / impact.
2. It was put open to get it going / fix a problem and they just haven't fixed it.
3. A lack of time / staffing to do a job properly.

Of course, we all know how important it is but unless the techs making the change / the managers pushing for jobs to be completed understand, it'll get ignored.

There is always option 4, they just don't care about security till it costs them, but the cost involved in doing this properly is fairly minimal so I doubt in most cases that's the issue...

Thanks,
Ayden Beeson

These services undoubtedly are good for detection, but by the time you get in contact with $insert_isp to get a prefix withdrawn the damage is already done.

It still amazes me after all these years large backbone networks trust smaller BGP peers with open filters.

There are many ways to automate filters, why don't they implement them?
My bet is until it costs them x (due to legal or direct attack), they don't want to spend x (in prevention), sounds like a typical security scenario to me.
