You have been called to help investigate a problem with someone in the WeTimesNews newspaper company who is sending e-mail messages to employees. The messages have spread false stories indicating that WeTimes News is on the verge of going out of business. Carbon copies of the messages have gone to all employees. Some of the messages have encouraged employees to look for jobs elsewhere. But the most recent message was even more damaging: It went to some of the newspaper's best clients, saying that the circulation numbers for WeTimesNews were false. Barbara Notis, the CEO, tells you that she is sure that the messages are coming from an insider because the messages show intimate knowledge of WeTimesNews operations. It's being sent from an e-mail address, thetruth@gxxyyzz.com. Barbar's IT manager checked the domain registration for gxxyyzz.com and found that it is registered through a service that holds proxy control of domains. Consequently, a court order would be required to find out the real owner of gxxyyzz.com. The attorney for WeTimesNews indicated that it would be possible to file a "John Doe" lawsuit and then use a subpoena to find the real owner of gxxyyzz.com. However, going that route would take time and, in the end, could easily produce nothing. Merely finding the owner of gxxyyzz.com wouldn't guarantee that it would also be possible to find out the owner of the e-mail address thetruth@gxxyyzz.com. For example, the domain gxxyyzz .com could belong to an e-mail service in a distant country, and the service could easily refuse to turn over the name of the owner of the e-mail address in question. Further, even if the service did turn over the name of the owner of the e-mail address, the name could very easily be a fake name. The most recent thing to happen is that Barbara received a private e-mail message from the perpetrator. It offered to stop the malicious e-mail campaign if she would send a "mere" \($10,000\) in Bitcoins. You contacted the police, but they refused to help, indicating that the case was too small for them to take on.
