Can you say psycho? At least that is what a person might think after learning about a cyberstalking campaign which seems more like something out of a horror flick than real life. However, an affidavit shows what a technically savvy yet twisted mind can do. The cyberstalking continued for more than a year and a half, using TOR, VPN and anonymous overseas texting and email services, until the FBI was able to recover forensic artifacts from a work computer and determine overlapping service providers with help from VPN service provider PureVPN.
