About

I'm a reformed black-hat computer hacker. After being the target of Operation Purple Obsidian, Operation Falcon, and Operation Belanos, I was arrested and sentenced to a total of four years in prison, the majority of which I spent in Britain's most secure prison, HMP Belmarsh, living among terrorists and former IRA members. Since then, I have gone on to reform myself and change for the better. You can hear more about my story by searching for the following publications on Google: • Darknet Diaries: Daniel The Paladin Episode #117 • Convicted TalkTalk Blackmailer Warns Young Hackers • TalkTalk Hacker Daniel Kelley Gives Up His Black Hat • After Prison, Hackers Face Tech Restrictions • Life After Cybercrime, One Day At A Time • A Former Hacker Wants To Stop Others Like Him • Businesses only care after they're attacked • Inside the Mind of Daniel Kelley, ex-Blackhat • What’s the NCA doing about cybercrime? Publications have been made on websites like Darknet Diaries, Vice, SecurityWeek, Computer Weekly, The Wall Street Journal, Cybercrime Magazine, Euro News, and Psybersafe. Since my reform, I've achieved and done a lot of great things, so here's a few bullet points of coverage: • Ranked position 11 on Open Bug Bounty among 25,000+ researchers • Conducted black-box and grey-box penetration tests for international clients • Gained extensive experience using a variety of offensive-hacking tools • Received hundreds of public acknowledgments and letters of recognition • Worked collaboratively with CIRT teams, system administrators, and government agencies • Contributed to over 100 bug bounty programs • Discovered and reported over 5,000 vulnerabilities, with 3,000 being remediated • Developed a non profit cyber threat intelligence platform • Founded a private cybersecurity community with 100+ members • Discovered WormGPT which was featured in 100+ media outlets and U.S. Congress Here's some security research stuff that I've accomplished: • CVE-2023-1372 • CVE-2023-1374 • Microsoft Hall of Fame • Esri Hall of Fame • BBC Hall of Fame • Sony Hall of Fame • Adobe Hall of Fame • AT&T Hall of Fame • Deutsche Telekom Hall of Fame • United Nations Hall of Fame • Duke Hall of Fame • AOL Hall of Fame • University of Twente Hall of Fame • Houzz Hall of Fame I'm currently trying to improve cybersecurity marketing and grow an agency. I've worked with 35+ leading cybersecurity firms to date.
