Bogus Bomb Threats Demand Bitcoin Disrupt Businesses

Bogus bomb threats created a scare across the country. A quick note here that I'll dive into more deeply next week. The big question at this time -- with MANY of the IP addresses found in email headers originating from Moscow, Russia, is this "Russian influence" designed to disrupt American commerce? or is this just a spammer looking for a new way to make money?

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:

(If you have a sample of one of these emails, please consider filling out a BitCoinAbuse.com/report - but please make sure to include the SENDING IP ADDRESS from the email headers!)

Email Bodies contain Spam-template randomization

Here are extracts from many of the spam messages. Note for example the [man | mercenary | recruited person] and [tronitrotoluene | Hexogen | Tetryl] substitutions. Or the [suspicious | unnatural | strange] [activity | behavior] or the [power the device | device will be blown up | power the bomb]. This is very characteristic spam behavior.

Subjects reported by the NCFTA include:

Subject: Better listen to me
Subject: Bomb is in your building
Subject: Do not panic
Subject: Do not waste your time
Subject: Dont get on my nerves
Subject: I advise you not to call the police
Subject: I've collected some very interesting content about you
Subject: keep calm
Subject: My device is inside your building
Subject: Think about how they can help you
Subject: Think twice
Subject: We can make a deal
Subject: You are my victim
Subject: You are responsible for people
Subject: Your building is under my control
Subject: Your life is in your hands
Subject: Your life can be ruined, concentrate
Subject: You're my victim

(If you have examples of other Subjects, please share them in the comments section)

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:

Porn Extortion Email tied to Password Breach

(An update to this post has been made at the end)

This weekend I received an email forwarded from a stranger.  They had received a threatening email and had shared it with a former student of mine to ask advice.  Fortunately, the correct advice in this case was "Ignore it."  But they still shared it with me in case we could use it to help others.

The email claims that the sender has planted malware on the recipient's computer and has observed them watching pornography online.   As evidence that they really have control of the computer, the email begins by sharing one of the recipient's former passwords.

They then threaten that they are going to release a video of the recipient recorded from their webcam while they watched the pornography unless they receive $1000 in Bitcoin.  The good news, as my former student knew, was that this was almost certainly an empty threat.   There have dozens of variations on this scheme, but it is based on the concept that if someone knows your password, they COULD know much more about you.  In this case, the password came from a data breach involving a gaming site where the recipient used to hang out online.  So, if you think to yourself "This must be real, they know my password!" just remember that there have been  HUNDREDS of data breaches where email addresses and their corresponding passwords have been leaked.  (The website "Have I Been Pwned?" has collected over 500 Million such email/password pair leaks.  In full disclosure, my personal email is in their database TEN times and my work email is in their database SIX times, which doesn't concern me because I follow the proper password practice of using different passwords on every site I visit.  Sites including Adobe, which asks for you to register before downloading software, and LinkedIn are among some of the giants who have had breaches that revealed passwords.  One list circulating on the dark web has 1.4 BILLION userids and passwords gathered from at least 250 distinct data breaches.)

Knowing that context, even if you happen to be one of those millions of Americans who have watched porn online.  DON'T PANIC!  This email is definitely a fake, using their knowledge of a breached password to try to convince you they have blackmail information about you.

We'll go ahead and share the exact text of the email, replacing only the password with the word YOURPASSWORDHERE.

YOURPASSWORDHERE is one of your passphrase. Lets get directly to the point. There is no one who has paid me to investigate you. You don't know me and you are most likely wondering why you are getting this mail?
In fact, I actually installed a malware on the X video clips (porn) web site and do you know what, you visited this site to experience fun (you know what I mean). When you were watching video clips, your browser initiated functioning as a RDP that has a key logger which provided me accessibility to your display screen and also cam. after that, my software obtained your entire contacts from your Messenger, Facebook, and email . After that I made a double-screen video. 1st part shows the video you were viewing (you've got a nice taste omg), and next part shows the view of your web cam, & its you. 
You have got not one but two alternatives. We will go through these choices in details:
First alternative is to neglect this email message. In such a case, I will send out your very own videotape to all of your contacts and also visualize about the embarrassment you will definitely get. And definitely if you happen to be in a romantic relationship, exactly how this will affect?
Latter solution is to compensate me $1000. Let us describe it as a donation. In such a case, I will asap delete your video. You can go forward your daily life like this never occurred and you surely will never hear back again from me.
You'll make the payment through Bitcoin (if you do not know this, search for "how to buy bitcoin" in Google). 
BTC Address: 192hBrF64LcTQUkQRmRAVgLRC5SQRCWshi[CASE sensitive so copy and paste it]
If you are thinking about going to the law, well, this email can not be traced back to me. I have taken care of my moves. I am not attempting to charge a fee a huge amount, I simply want to be rewarded. You have one day in order to pay. I have a specific pixel in this e-mail, and now I know that you have read through this mail. If I do not receive the BitCoins, I will definately send your video to all of your contacts including family members, co-workers, and so forth. Having said that, if I receive the payment, I'll destroy the video right away. If you really want proof, reply with Yes & I definitely will send out your video recording to your 5 friends. This is the non-negotiable offer and thus don't waste mine time & yours by responding to this message.
This particular scam was first seen in the wild back in December of 2017, though some similar versions predate it.  However, beginning in late May the scam kicked up in prevalence, and in the second week of July, apparently someone's botnet started sending this spam in SERIOUS volumes, as there have been more than a dozen news stories just in the past ten days about the scam.

Here's one such warning article from the Better Business Bureau's Scam Tracker.

One thing to mention is that the Bitcoin address means that we can track whether payments have been made to the criminal.  It seems that this particular botnet is using a very large number of unique bitcoin addresses.  It would be extremely helpful to this investigation if you could share in the comments section what Bitcoin address (the "BTC Address") was seen in your copy of the spam email.

As always, we encourage any victim of a cyber crime to report it to the FBI's Internet Crime and Complaint Center by visiting ic3.gov:



Please feel free to share this note with your friends!
Thank you!

UPDATE!!!

The excellent analysts at the SANS Internet Storm Center have also been gathering bitcoin addresses from victims.  In their sample so far, 17% of the Bitcoins have received payments totalling $235,000, so people truly are falling victim to this scam!

Please continue to share this post and encourage people to add their Bitcoin addresses as a comment below!
