Hi, I'm Simon Bell, a Web Security Consultant, Full-Stack Secure Web Developer, Researcher, Writer, and Educator.

Skills / Tech:



PhD in Cyber Security

Thesis title: How Many Phish Can Tweet? Investigating the Effectiveness of Twitter's Phishing and Malware Defence System.

Thesis summary: an empirical, data-driven approach to investigate cybercrime on Twitter. We conduct numerous measurement studies to analyse Twitter’s phishing and malware threat intelligence and defence mechanisms. Results explore how well-protected Twitter users are against cyber-attacks.

My thesis was conducted under the supervision of Professor Peter Komisarczuk, Professor Kenny Paterson, and Professor Lorenzo Cavallaro at the Information Security Group (ISG), Royal Holloway, University of London.

Secure Honey: SSH Honeypot

For my BSc in Computer Science final year project I built an SSH honeypot in C. I then deployed the honeypot to AWS to collect and analyse empirical data on SSH cyber-attacks.
