Although common systems analyze only landing pages or conduct browser interactions limited to a specific attack, little effort has been made to follow such sequences of web pages to collect multi-step SE attacks. ![]() Also, different browser interactions executed on a web page often branch to multiple sequences to redirect users to different SE attacks. Aiming to effectively lure users, some SE attacks, which we call multi-step SE attacks, constitute a sequence of web pages starting from a landing page and require browser interactions at each web page. Web-based social engineering (SE) attacks manipulate users to perform specific actions, such as downloading malware and exposing personal information. Given the magnitude of the discovered abuse, we engineer features that characterize FLIS pages and build a classifier to identify FLIS pages with high accuracy and low false positives, in an effort to help human analysts identify malicious services and, whenever appropriate, initiate content-takedown requests. At the same time, we encounter substandard advertisement setups by the FLIS parties, along with potential trademark infringements through the abuse of domain names and logos of popular TV channels. On the other hand, we find that FLIS parties are often reported for copyright violations and host their infrastructure predominantly in Europe and Belize. On the one hand, our analysis reveals that users of FLIS websites are generally exposed to deceptive advertisements, malware, malicious browser extensions, and fraudulent scams. ![]() We develop an infrastructure that enables us to perform more than 850,000 visits by identifying 5,685 free live streaming domains, and analyze more than 1 Terabyte of traffic to map the parties that constitute the FLIS ecosystem. This paper presents a comprehensive analysis of the FLIS ecosystem by mapping all parties involved in the anonymous broadcast of live streams, discovering their modus operandi, and quantifying the consequences for common Internet users who utilize these services. ![]() Despite the immense popularity of these services, little is known about the parties that facilitate it and maintain webpages to index links for free viewership. Free live streaming (FLIS) services attract millions of viewers and make heavy use of deceptive advertisements. Recent years have seen extensive growth of services enabling free broadcasts of live streams on the Web.
