TexasDex writes "The Register reports: Myron Tereshchuk, 42, of Maryland, pleaded guilty to "attempted extortion affecting commerce" for sending threatening messages to a competing patent firm, including a demand for $17 million in exchange for not revealing sensitive information. He was clever in hiding his tracks, the messages came from two different homes and a dentist's office, all of which turned out to be running unsecured WAPs. He also avoided a web bug sent by the firm, and managed to penetrate the company's computer system. But he made a few mistakes. First of all he was already a prime suspect due to "past altercations between Tereshchuk and the company". But "the clearest sign came when he issued the $17m extortion demand, and instructed the company to 'make the check payable to Myron Tereshchuk.'""
