As the acting cybersecurity chief of a federal agency, Timothy DeFoggi should have been well versed in the digital footprints users leave behind online when they visit web sites and download images. But DeFoggi—convicted today in Nebraska on three child porn charges including conspiracy to solicit and distribute child porn—must have believed his use of the Tor anonymizing network shielded him from federal investigators. He’s the sixth suspect to make this mistake in Operation Torpedo, an FBI operation that targeted three Tor-based child porn sites and that used controversial methods to unmask anonymized users. But DeFoggi’s conviction is perhaps more surprising than others owing to the fact that he worked at one time as the acting cybersecurity director of the U.S. Department of Health and Human Services...DeFoggi became part of that sting after becoming a registered member of PedoBook in March 2012 where he remained active until December that year when the FBI shuttered it. During this time DeFoggi, who described himself as “having many perversions,” solicited child porn images from other members, viewed images and exchanged private messages with other members expressing interest in raping, beating and murdering infants and toddlers.
