A botnet is a collection\u003C\/p\u003E\u003Cp\u003Eof infected machines that receive commands from the botmaster, a person, group or nation-\u003C\/p\u003E\u003Cp\u003Estate, to perform malicious actions. Instead of \u0022cleaning\u0022 individual infections, one can sever\u003C\/p\u003E\u003Cp\u003Ethe method of communication between a botmaster and her zombies by attempting a botnet\u003C\/p\u003E\u003Cp\u003Etakedown, which contains the botnet and its malicious actions.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003EUnfortunately, takedowns are currently performed without technical rigor nor are there\u003C\/p\u003E\u003Cp\u003Eautomated and independent means to measure success or assist in performing them. Our\u003C\/p\u003E\u003Cp\u003Eresearch focuses on understanding the criminal infrastructure that enables communication\u003C\/p\u003E\u003Cp\u003Ebetween a botmaster and her zombies in order to measure attempts at, and to perform,\u003C\/p\u003E\u003Cp\u003Esuccessful takedowns. We show that by interrogating malware and performing large-scale\u003C\/p\u003E\u003Cp\u003Eanalysis of passively collected network data, we can measure if a past botnet takedown was\u003C\/p\u003E\u003Cp\u003Esuccessful and use the same techniques to perform more comprehensive takedowns in the\u003C\/p\u003E\u003Cp\u003Efuture.\u003C\/p\u003E\u003Cp\u003E \u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Understanding DNS-based Criminal Infrastructure for Informing Takedowns"}],"uid":"27707","created_gmt":"2015-07-10 09:12:45","changed_gmt":"2016-10-08 02:12:26","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2015-07-15T11:00:00-04:00","event_time_end":"2015-07-15T13:00:00-04:00","event_time_end_last":"2015-07-15T13:00:00-04:00","gmt_time_start":"2015-07-15 15:00:00","gmt_time_end":"2015-07-15 17:00:00","gmt_time_end_last":"2015-07-15 17:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
