Hackers, Swindlers, and Trolls: Understanding and Measuring Abuse on Online Services

Abstract

Online services are abused by a multitude of malicious parties, from cybercriminals using them to monetize botnets and malware, to scammers looking to defraud innocent users, to trolls spreading hate speech and bullying. Despite the threats that they pose to the safety of Internet users, we still lack a satisfactory knowledge of how different types of malicious users operate. In this talk I will provide an overview of our recent work in the area. I will first illustrate the findings that we made when deploying honeypot accounts on Gmail and deliberately giving access to them to cybercriminals. I will then talk about the problem of scams happening on online dating sites, focusing on why blocking malicious activity on these platforms is a particularly challenging task. Finally, I will talk about our measurement study of 4chan, the “dark underbelly of the Internet,” in which we characterized “raid” behavior, a phenomenon that sees online trolls gather and deliberately attacking an entity on a third party service, such as a Youtube video or a Twitter account.
