Homeless Vikings

 

Don't try it at home

 

How easy is this to pull off?

  • You can use a shady ISP
  • You can BE a shady ISP
  • You can work at an ISP and be shady

But even given none of the above, "mistakes" happen.

  • Even top tier ISP's can be socially engineered into forgetting to use proper BGP filters
  • There is an inversely proportional relationship between size of customer and ease of filtering
  • ISP's tend to believe their peers
  • Top tiers are focused on mitigating DDOS and Worm attacks, and typically don't consider a 15 minute "misconfiguration" to be a security problem.
