A measurement methodology and emulator extension is presented to reproduce these control-path performance artifacts, restoring the fidelity of emulation in SDN switch control path.
Tracking Ransomware End-to-end
- D. Huang, M. Aliapoulios, Damon McCoy
- Computer ScienceIEEE Symposium on Security and Privacy
- 20 May 2018
This paper creates a measurement framework that is used to perform a large-scale, two-year, end-to-end measurement of ransomware payments, victims, and operators, and finds that many ransomware operators cashed out using BTC-e, a now-defunct Bitcoin exchange.
IoT Inspector: Crowdsourcing Labeled Network Traffic from Smart Home Devices at Scale
- D. Huang, Noah J. Apthorpe, Gunes Acar, Frank H. Li, N. Feamster
- Computer ScienceArXiv
- 21 September 2019
This work crowdsource the largest known dataset of labeled network traffic from smart home devices from within real-world home networks and demonstrates how this data enables new research into smart homes through two case studies focused on security and privacy.
Framing Dependencies Introduced by Underground Commoditization
- Kurt Thomas, D. Huang, G. Vigna
- Computer ScienceWorkshop on the Economics of Information Security
- 22 June 2015
This paper surveys a wealth of existing research in order to systematize the community’s understanding of the underground economy and develops a taxonomy of profit centers and support centers for reasoning about the flow of capital within the black market.
Stressing Out: Bitcoin "Stress Testing"
- Khaled Baqer, D. Huang, Damon McCoy, N. Weaver
- Computer ScienceFinancial Cryptography Workshops
- 22 February 2016
An empirical study of a recent spam campaign that resulted in a DoS attack on Bitcoin, using a clustering based method to detect spam transactions and pointing out changes that could be made to Bitcoin transaction fees that would mitigate some of the spam techniques used to effectively DoS Bitcoin.
Botcoin: Monetizing Stolen Cycles
- D. Huang, Hitesh Dharmdasani, Kirill Levchenko
- Computer ScienceNetwork and Distributed System Security Symposium
- 2014
This work conducts the first comprehensive study of Bitcoin mining malware, and deduces the amount of money a number of mining botnets have made by carefully reconstructing the Bitcoin transaction records.
Backpage and Bitcoin: Uncovering Human Traffickers
- Rebecca S. Portnoff, D. Huang, Periwinkle Doerfler, Sadia Afroz, Damon McCoy
- Computer ScienceKnowledge Discovery and Data Mining
- 13 August 2017
A machine learning classifier that uses stylometry to distinguish between ads posted by the same vs. different authors with 90% TPR and 1% FPR is developed and a linking technique that takes advantage of leakages from the Bitcoin mempool, blockchain and sex ad site, to link a subset of sex ads to Bitcoin public wallets and transactions is designed.
