Carnivore is a controversial software that has been used by FBI for few years now. The news is FBI is retiring Carnivore software now and are going to use other commercial products ( I am sure other products are smarter than Carnivore was).
“FBI surveillance experts have put their once-controversial Carnivore Internet surveillance tool out to pasture, preferring instead to use commercial products to eavesdrop on network traffic, according to documents released Friday”
