We developed a data-driven method for identifying, quantifying, and comparing ransom payments in the Bitcoin ecosystem from 35 ransomware families. The study was conducted in partnership with Bernhard Haslhofer from the Austrian Institute of Technology (AIT) and Benoît Dupont from the Université de Montréal (UdeM). It resulted in a paper that will be presented at the 17th Annual Workshop on the Economics of Information Security (WEIS2018) in Innsbruck, Austria, along other renown academic researchers. This blog post provides a quick summary of the methodology developed for tracing ransomware payments and the study's findings.

Additionally, it fully encrypts and integrity checks it network traffic with session keys. It was first presented at GoSec 2017 in Montreal and was found using a new honeypot SSH tool.

This backdoor was first used in 2012 as part of the 'sebd' rootkit but seems to have been reactivated within the scope of a rising botnet.
