The landscape of domain name typosquatting: techniques and countermeasures - Spaulding et al. arXiv upload 9 Mar 2016. We round up our series of posts on internet deceptions by looking at domain squatting. My "favourite" advanced technique is bitsquatting, which turns out to be a great demonstration of the inevitable failures that occur with sufficient … Continue reading The landscape of domain name typosquatting: techniques and countermeasures

Understanding malvertising through ad-injecting browser extensions
Understanding malvertising through ad-injecting browser extensions- Xing et al., WWW 2015. Be careful what browser extensions you install. Some ad networks have started to offer browser extension developers an opportunity to monetise their work, and in this study Xing et al. show that of the 292 Chrome browser extensions in their survey which inject ads, … Continue reading Understanding malvertising through ad-injecting browser extensions
Knowing your enemy: understanding and detecting malicious web advertising
Knowing your enemy: understanding and detecting malicious web advertising - Li at al. CCS, 2012 ... hackers and con-artists have found web ads to be a low-cost and highly effective means to conduct malicious and fraudulent activities. In this paper, we broadly refer to such ad-related malicious activities as malvertising, which can happen to any … Continue reading Knowing your enemy: understanding and detecting malicious web advertising
PharmaLeaks: Understanding the business of online pharmaceutical affiliate programs
PharmaLeaks: Understanding the business of online pharmaceutical affiliate programs - McCoy et al., USENIX Security, 2012 Yesterday we looked at the technology infrastructure supporting spam-based advertising businesses. Today's paper gives a fascinating look at the business model. How this is possible is itself a very interesting story which we'll get to shortly. The authors gained … Continue reading PharmaLeaks: Understanding the business of online pharmaceutical affiliate programs
Dynamic Time Warping averaging of time series allows faster and more accurate classification
Dynamic Time Warping averaging of time series allows faster and more accurate classification - Petitjean et al. ICDM 2014 For most time series classification problems, using the Nearest Neighbour algorithm (find the nearest neighbour within the training set to the query) is the technique of choice. Moreover, when determining the distance to neighbours, we want … Continue reading Dynamic Time Warping averaging of time series allows faster and more accurate classification
Time series classification under more realistic assumptions
Time series classification under more realistic assumptions - Hu et al. ICDM 2013 This paper sheds light on the gap between research results in time series classification, and what you're likely to see if you try to apply the results in the real world. And having identified the gap of course, the authors go on … Continue reading Time series classification under more realistic assumptions
Searching and mining trillions of time series subsequences under Dynamic Time Warping
Searching and mining trillions of time series subsequences under dynamic time warping - Rakthanmanon et al. SIGKDD 2012 What an astonishing paper this is! By 2012, Dynamic Time Warping had been shown to be the time series similarity measure that generally performs the best for matching, but because of its computational complexity researchers and practitioners … Continue reading Searching and mining trillions of time series subsequences under Dynamic Time Warping
Towards parameter-free data mining
Towards Parameter-Free Data Mining - Keogh et al. SIGKDD 2004 Another time series paper today from the Facebook Gorilla references. Keogh et al. describe an incredibly simple and easy to implement scheme that does surprisingly well with clustering, anomaly detection, and classification tasks over time series data. As per the title of the paper, it … Continue reading Towards parameter-free data mining
Finding surprising patterns in a time series database in linear time and space
Finding Surprising Patterns in a Time Series Database in Linear Time and Space - Keogh et al. SIGKDD 2002 In the Facebook Gorilla paper, the authors mentioned a number of additional time series analysis techniques they'd like to add to the system over time. Today's paper is one of them, and it deals with the … Continue reading Finding surprising patterns in a time series database in linear time and space
NOVA: A Log-Structured File System for Hybrid Volatile/Non-Volatile Main Memories
NOVA: A Log-structured file system for hybrid volatile/non-volatile main memories - Xu & Swanson 2016 Another paper looking at the design implications of mixed DRAM and NVMM systems (it's the future!), this time in the context of file systems. (NVMM = Non-volatile Main Memory). Hybrid DRAM/NVMM storage systems present a host of opportunities and challenges … Continue reading NOVA: A Log-Structured File System for Hybrid Volatile/Non-Volatile Main Memories
