Advanced web bots are especially appealing to malicious web bot creators, due to their browserlike fingerprint and humanlike behaviour that reduce their detectability. This work proposes a web bot detection framework that comprises two detection modules: (i) a detection module that utilises web logs, and (ii) a detection module that leverages mouse movements. The framework combines the results of each module in a novel way to capture the different temporal characteristics of the web logs and the mouse movements, as well as the spatial characteristics of the mouse movements. We assess its effectiveness on web bots of two levels of evasiveness: (a)\n            <jats:italic>moderate web bots<\/jats:italic>\n            that have a browser fingerprint and (b)\n            <jats:italic>advanced web bots<\/jats:italic>\n            that have a browser fingerprint and also exhibit a humanlike behaviour. We show that combining web logs with visitors\u2019 mouse movements is more effective and robust toward detecting advanced web bots that try to evade detection, as opposed to using only one of those approaches.\n          <\/jats:p>","DOI":"10.1145\/3447815","type":"journal-article","created":{"date-parts":[[2021,4,16]],"date-time":"2021-04-16T00:47:40Z","timestamp":1618534060000},"page":"1-26","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":26,"title":["Detection of Advanced Web Bots by Combining Web Logs with Mouse Behavioural Biometrics"],"prefix":"10.1145","volume":"2","author":[{"given":"Christos","family":"Iliou","sequence":"first","affiliation":[{"name":"Information Technologies Institute, CERTH and BU-CERT, Bournemouth University, Bournemouth, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theodoros","family":"Kostoulas","sequence":"additional","affiliation":[{"name":"Department of Information &amp; Communication Systems Engineering, University of the Aegean and Department of Computing and Informatics, Bournemouth University, Bournemouth, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Theodora","family":"Tsikrika","sequence":"additional","affiliation":[{"name":"Information Technologies Institute, CERTH, Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6132-3004","authenticated-orcid":false,"given":"Vasilis","family":"Katos","sequence":"additional","affiliation":[{"name":"BU-CERT, Bournemouth University, Bournemouth, United Kingdom"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefanos","family":"Vrochidis","sequence":"additional","affiliation":[{"name":"Information Technologies Institute, CERTH, Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ioannis","family":"Kompatsiaris","sequence":"additional","affiliation":[{"name":"Information Technologies Institute, CERTH, Thessaloniki, Greece"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2021,6,8]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"Akamai. 2018.
