According to this Verizon blog entry, we will see sanitized intrusion data from the U.S. Secret Service alongside Verizon Business Service's own data in their next Data Breach Investigations Report (due later in 2010).
Apparently the U.S. Secret Service started using Verizon's VerIS framework and has decided to share at least some of their casework data.
Very cool. Maybe this will set a precedent for others in the law enforcement world to start sharing real world data (where they can) so that system defenders everywhere can benefit from knowing more about the tactics and true offensive capabilities of the parties coming after them.
