Bitcoin Blackmail Threatens to Detonate Bombs in Offices, Schools

In offices and universities all across the country, the same threat appeared in email inboxes: Pay $20,000 worth of bitcoin, or a bomb will detonate in your building. It appears to be a steep escalation of a bitcoin blackmail tactic that took off this summer. In that scheme, victims received an email claiming that a hacker commandeered their webcam while they were watching pornography and would release the resulting photos publicly if the target didn't pay a small amount in bitcoin.
