In March 2011, Stewart was examining a piece of malware that looked different from the typical handiwork of Russian or Eastern European identity thieves. As he began to explore the command nodes connected to the suspicious code, Stewart noticed that since 2004, about a dozen had been registered under the same one or two names—Tawnya Grilth or Eric Charles—both listing the same Hotmail account and usually a city in California. Several were registered in the wonderfully misspelled city of Sin Digoo.

Sin Digoo! LOL!!
