In order to continue their malevolent activities without being detected, cyber criminals make efforts to conceal the core servers (e.g., C&C servers, exploit servers, and drop-zone servers) in the malicious web infrastructure. Such deliberate invisibility of those concealed malicious servers, however, makes them particularly distinguishable from benign web servers that are usually promoted to be public. In this paper, we conduct the first large-scale measurement study to investigate the visibility of both malicious and benign servers. From our intensive analysis of over 100,000 benign servers, 45,000 malicious servers and 40,000 redirections, we identify a set of distinct features of malicious web infrastructures from their locations, structures, roles, and relationships perspectives, and propose a lightweight yet effective detection system called VisHunter. VisHunter identifies malicious redirections from visible servers to invisible servers at the entryway of malicious web infrastructures. We evaluate VisHunter on both online public data and large-scale enterprise network traffic, and demonstrate that VisHunter can achieve an average 96.2% detection rate with only 0.9% false positive rate on the real enterprise network traffic.","PeriodicalId":274591,"journal":{"name":"IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129581645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a large search engine as a case study, we propose a machine learning based analysis framework, called FOCUS, as the first step to automatically debug high search response time (HSRT) in search logs. The output of FOCUS offers a promising starting point for operators' further investigation. FOCUS has been deployed in one of the largest search engines for 2.5 months and analyzed about one billion search logs. Compared with a previous approach, FOCUS generates 90% less items for investigation and achieves both higher recall and higher precision. The results of FOCUS enable us to make several interesting observations. For example, we find that popular queries are more image-intensive (e.g., TV series and shopping), but they have relatively low SRT because they are cached well by servers. Additionally, as suggested by the first-month analysis results of FOCUS, we conduct an optimization on image transmission time. A one-month real-world deployment shows that we successfully reduce the 80th percentile of search response time by 253ms, and reduce the fraction of HSRT by one third.","PeriodicalId":274591,"journal":{"name":"IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127319958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this situation, we find that there is misaligned sensing of channel idleness, and also short-term unfairness in access to the medium. We demonstrate that existing analysis techniques (or, extensions thereof) are unable to account for these features, resulting in inaccurate prediction of the performance. Focusing on the case in which transmitters are equidistant from one another, and also each receiver is equidistant from all the transmitters, we provide a detailed stochastic model that accurately captures the system evolution. Since an exact analysis of this model is computationally intractable, we develop a novel approximate, but accurate, analysis that uses a parsimonious state representation for computational tractability. Numerical experiments show, the approximate analysis predicts the system throughput to a relative accuracy of 2-3%, and collision probabilities to a relative accuracy of 3-8% compared to simulations. Interestingly, we observe that as propagation delay increases, the collision probability of a node initially increases, but then flattens out, contrary to what one might intuitively expect. Finally, we also demonstrate how to optimize slot duration using the approximate analysis for maximizing system throughput.","PeriodicalId":274591,"journal":{"name":"IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131017554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, WiFi hop latency in the wild remains largely unknown. In this paper, we first propose an effective approach to break down the round trip network latency. Then we provide the first systematic study on WiFi hop latency in the wild based on the latency and WiFi factors collected from 47 APs on T university campus for two months. We observe that WiFi hop can be the weakest link in the round trip network latency: more than 50% (10%) of TCP packets suffer from WiFi hop latency larger than 20ms (100ms), and WiFi hop latency occupies more than 60% in more than half of the round trip network latency. To help understand, troubleshoot, and optimize WiFi hop latency for WiFi APs in general, we train a decision tree model. Based on the model's output, we are able to reduce the median latency by 80% from 50ms to 10ms in one real case, and reduce the maximum latency from 250ms to 50ms in another real case.","PeriodicalId":274591,"journal":{"name":"IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123124748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most video encoding standards such as H.264 and MPEG-4 compress the temporal redundancy in a video stream using difference coding, which only encodes the residual image between a frame and its reference frame. Difference coding can efficiently compress a video stream, but it causes side-channel information leakage even though the video stream is encrypted, as reported in this paper. Particularly, we observe that the traffic patterns of an encrypted video stream are different when a user conducts different basic activities of daily living, which must be kept private from third parties as obliged by HIPAA regulations. We also observe that by exploiting this side-channel information leakage, attackers can readily infer a user's basic activities of daily living based on only the traffic size data of an encrypted video stream. We validate such an attack using two off-the-shelf cameras, and the results indicate that the user's basic activities of daily living can be recognized with a high accuracy.","PeriodicalId":274591,"journal":{"name":"IEEE INFOCOM 2016 - The 35th Annual IEEE International Conference on Computer Communications","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126304978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
