The Despicable, No Good, Blackmail Campaign Targeting ... Imaginary Friends?

Natalia here speaks to our imaginary friend 185.150.184.92

In which we confront the pundits' assumption that the embarrasment-based extortion attempts would grow more “sophisticated and credible” over time with real data.

It's a problem that should not exist. 

It's a scam that's so obvious it should not work.

Yet we still see a stream of reports about people who have actually gone out and bought their first bitcoins (or more likely fractions of one) in order to pay off blackmailers who claim to have in their possesion videos that record the vicim while performing some autoerotic activity and the material they were supposedly viewing while performing that activity.

And occasionally one of those messages actually find their way to some pundit's inbox (like yours truly), and at times some of those pundits will say things like that those messages represent a real problem and will evolve to be ever more sophisticated.

Note: This piece is also available, with more basic formatting but with no trackers, here.

I am here to tell you that

1. That incriminating video does not exist, and
2. The pundits who predicted that those scams would evolve to become more sophisticated were wrong.

If you stumbled on this article because one of those messages reached you, it's safe to not read any further and please do ignore the extortion attempt.

I wrote a piece in 2019 The 'sextortion' Scams: The Numbers Show That What We Have Is A Failure Of Education, also available without trackers, where the summary is,

Every time I see one of those messages reach a mailbox that is actually read by one or more persons, I also see delivery attempts for near identical messages aimed at a subset of my now more than three hundred thousand spamtraps, also known imaginary friends.

Over the years since the piece was originally written, I have added several updates — generally when some of this nonsense reaches a mailbox I read — and while I have seen the messages in several languages, no real development beyond some variations in wording has happened.

Whenever one of those things does reach an inbox, my sequence of actions is generally to save the message and add it to the archive, see if the sending IP address has already entered the blocklist that is later exported and add it by hand if not. Then check if the number of trapped addesses has swelled recently by checking the log file from the export script

$ tail -n 96 /var/log/traplistcounts

See if there is a sharp increase since the last blocklist export

$ doas spamdb | grep -c TRAPPED

Then check for related activity in the log

$ tail -n 500 -f /var/log/spamd

Check for the full subject in the same log file

$ grep "You are in really big troubles therefore, you much better read" /var/log/spamd

Then check older, archived logs to see how long this campaign has been going on for

$ zgrep "You are in really big troubles therefore, you much better read" /var/log/spamd.0.gz

This time, the campaign had not gone on for long enough to show traces in the older archive, so I go on to extracting the sending IP addresses

$ grep "You are in really big troubles therefore, you much better read" /var/log/spamd | awk '{print $6}' | tr -d ':' | sort -u

Check for activity from one of the extracted addresses

$ grep 183.111.115.4 /var/log/spamd | tee wankstortion/20221123_trapped_183.111.115.4.txt

Extract the sender IP addresses to an environment variable to use in the next oneliner,

$ grep trouble /var/log/spamd | awk '{print $6}' | tr -d ':' | sort -u | grep -vc BLACK | tee -a wankstortion/20221123_campaign_ip_addresses.txt

which will record all activity involving those IP addresses since the last log rotation:

$ for foo in $troubles ; do grep $foo /var/log/spamd | tee -a wankstortion/20221123_campaign_log_extract.txt ; done

You will find all those files, along with some earlier samples, and by the time you read this, possibly even newer samples, in the archive.

When something of the sort inboxes, I probably will go on adding to the archive, and if I have time on my hands, also run similar extraction activities as the ones I just described. But unless something unexpected such as actual development in the senders' methods occurs, I will not bother to write about it.

The subject is simply not worth attention past persuading supposed victims to not bother to get bitcoins or spend any they might have to hand. None of my imaginary friends have, and they are just as fine as they were before somebot tried to scam them.

Good night and good luck.
