Abstract
Lawful Interception is a monitoring access for law enforcement agencies, but also one of the primary data sources of many surveillance programs. (Almost?) every Internet service provider needs to provide LI functionality in its routers. However, LI exposes a larger attack surface to the one being surveilled than any router should. Could this be a mistake?

This short talk will cover the standards, devices and implementation of a mandatory part of our western Internet infrastructure. The central question is whether an overarching interception functionality might actually put national Internet infrastructure at a higher risk of being attacked successfully.

The question is approached in this talk from a purely technical point of view, looking at how LI functionality is implemented by a major vendor and what issues arise from that implementation. Routers and other devices may get hurt in the process.
