SIGMETRICS paper accepted: large-scale measurement study of the EOSIO blockchain ecosystem

Although EOSIO is the first widely adopted high throughput Delegated Proof of Stake system with millions of accounts and billions of transactions, little is known about its ecosystem. This paper performs a large-scale measurement study of the EOSIO blockchain and its associated DApps, develops techniques to automatically detect bots and fraudulent activity finding thousands of bot accounts (over 30% of the accounts in the platform) and real-world attacks (301 attack accounts): 80 attack accounts identified have been confirmed by DApp teams, causing 828,824 EOS tokens losses (roughly 2.6 million US$).

ICWSM paper accepted: political information diffusion in a Multi-lingual Social Network

This paper presents a characterisation of a multilingual social network in India called ShareChat. The authors collect an exhaustive dataset across 72 weeks before and during the Indian general elections of 2019, across 14 languages, investigating the cross lingual dynamics by clustering visually similar images together, and exploring how they move across language barriers.

INFOCOM 2020 Paper accepted: a large scale study of home security cameras

Home Security Cameras (HSCs) are now commonplace and constitute a growing part of the wider online video ecosystem. This paper
studies a major HSC provider (15.4M streams, 211K users). The study explores the per-user behaviour, identifying core clusters of users and extracts and identifies privacy risks and potential mitigations.

Preprint released. Leveraging Data Science To Combat COVID-19: A Comprehensive Review

This paper attempts to systematise ongoing data science activities related to COVID-19. The paper reviews the rapidly growing body research, surveys public datasets/repositories identifies common challenges and pitfalls observed across the surveyed works. We also created a live resource repository that we intend to keep updated with the latest resources including new papers and datasets.

WWW 2020 best student paper award

Our paper “Mobile App Squatting” has been received the best student paper award at WWW 2020!

In “App Squatting”, attackers release apps with identifiers (e.g., app name or package name) that are confusingly similar to those of popular apps or well-known Internet brands. This paper presents the first in-depth measurement study of app squatting showing its prevalence and implications. The paper develops and releases a tool (AppCrazy) for automatically generating variations of app identifiers and applies it to the top-500 most popular apps in Google Play, identifying 10,553 squatting apps (an average of over 20 squatting apps for each legitimate one).
While more than half are malicious mobile app markets have not been successful in identifying and eliminating squatting apps.

Workshop organisation (ICE-SoGo)

Members of the lab are organising the Information-Centric Economic, Societal and Governance Workshop (ICE-SoGo), which will be co-located with the 7th ACM Conference on Information-Centric Networking in Montreal, Canada. 

The aim of ICE-SoGo is to foster discussions regarding economic, social and governance factors involved in deploying, operating and regulating information-centricity within the Internet. The workshop encourages a broad interpretation of “information-centricity”, and would welcome research related to Information Centric Networks (ICNs), Content Delivery Networks (CDNs), Cloud Storage, and even the Web more generally. Submitted papers must be at most six (6) pages long, but we also welcome shorter position papers.
