This diary is an update to  Sextortion - Follow the Money which tracks some of the BTC addresses related the Sextortion campaign still in the wild, but seemingly tailing off at this time.

First a little history.  Within a couple of days of the beginning of the campaign (July 10th), we were able to cobble together 20 BTC addresses to monitor to see if we could characterize this campaign. We were happy with that. Once some of the ISC contacts heard of what we were doing the number being tracked snowballed to 334 BTC Addresses by July 28th. The momentum continued, to today, where thanks to the generosity of ISC readers we are now  tracking 426 BTC addresses we believe to be associated with this campaign.

To get this over with right away, this is over $200,000 in payments on 56 BTC addresses and the bad guys still have not started moving this money out.  You will find that the value of the payments has actually dropped since the first update.  This is because the value of Bitcoins has dropped substantially since the initial update.  This might also be a contributing factor to why the money has not moved out yet.

What sort of things has the monitoring revealed?

~13% - percentage of the BTC addresses with payments. (56 out of 426)

132 – number of payments received on the 56 BTC addresses with payments.

~$207,000 USD - Total value of all the payments stored in the 56 BTC Addresses. The 426 addresses we are tracking are thought to be an insignificant subset of those involved in the campaign, so the overall value of this campaign will be many times higher.

9 – Most number of payments on one BTC address. While most BTC addresses have zero or one payment, there is some small amount of BTC address reuse in the campaign.

Campaign emails, and payments appear to have slowed to a trickle over the last month, and I have not seen a payment on any monitored address in just over a month. So this campaign seems to have largely run its course.
