TRAWL: Protection against rogue sites for the masses

Abstract:
The number of smartphones reached 3.4 billion in the third quarter of 2016 [1]. These devices facilitate our daily lives and have become the primary way of accessing the web. Although all desktop browsers filter rogue websites, their mobile counterparts often do not filter them at all, exposing their users to websites serving malware or hosting phishing attacks. In this paper we revisit the anti-phishing filtering mechanism which is offered in the most popular web browsers of Android, iOS and Windows Phone. Our results show that mobile users are still unprotected against phishing attacks, as most of the browsers are unable to filter phishing URLs. Thus, we implement and evaluate TRAWL (TRAnsparent Web protection for alL), as a cost effective security control that provides DNS and URL filtering using several blacklists.
