IF YOU HAVE SAMPLES OF THE EMAIL, PLEASE REPORT THEM
The more emails we have to analyze, the better our understanding of this threat will be. While reporting to the FBI's IC3.gov is a great idea, and highly encouraged, that hides the details from security researchers such as myself. One great place to report any type of fraudulent bitcoin activity is "BitCoinAbuse.com". If you decide to report there, please extract the sending IP address and the email Subject from your spam and include them as part of the report. We can cluster on both of those things. (Including the bitcoin address used is a given.)Extracts taken from BitCoinAbuse.com follow below. You can read the original reports yourselves here:

These were EVERYWHERE - NOT targeted
Dozens of law enforcement agencies tweeted about these threats being received in their local area. If you are aware of such "official" tweets, please leave a link to the Twitter Status report in the comments section below.
Even AFTER it was well known that these were hoaxes, many law enforcement agencies continued to respond with full bomb squad roll-outs. Given the history in Oklahoma City, this was especially understandable there, but wasted a tremendous amount of resources as they responded to AT LEAST thirteen threats just in that city!
Here are a few examples, and then a longer list in Table form:

In fact, every sending IP we have seen at Cisco Talos from the bomb threat email attack was sent through IP space owned by reg.ru. The OSINT IoC data gathered in the Extortion-Scam.pdf sent by NCFTA included at least one BTC address that was used in sextortion, but NOT (AFAICT) in the actual bomb campaign. 1P55eXM8gxmwjSbqEpBWLBBvJQ7C1BmRH3
ReplyDeleteThat's great information! Thank you! Talos is doing a great job as usual!
DeleteA couple of those email subjects from NCFTA also look like they are the "we made a video of you watching porn" instead of the bomb ones. Will ask for clarification.
