Abuser: Bomb threat email, subj: "Do not panic"
Partial email message body: "Good day. My mercenary carried the explosive device (tronitrotoluene) into the building where your company is located. It was constructed according to my instructions. It can be hidden anywhere because of its small size, it can not damage the supporting building structure, but there will be many victims in the case of its detonation. My mercenary keeps the area under the control. If any unusual behavioror policeman is noticed the device will be exploded. I would like to suggest you a deal. You transfer me 20'000 usd in Bitcoin and explosive will not explode, but don't try to cheat -I assure you that I will withdraw my man solely after 3 confirmations in blockchain. Here is my Bitcoin address : 1BTuxsCpAGtCzcszvFV2g4beqAZ2AUnyFh"
