HackMiami began as a group of computer science and engineering students having biweekly meetings held at Florida International University.

In 2011, the organization pivoted to the a different business model of security consultation services and niche event planning in lieu of managing a membership based hackerspace.

In the year 2022, at DEFCON 30 Conference in Las Vegas, Rod Soto and Jonathan Respeto with a team composed of Hackmiami and Pacific Hackers members won Red Alert ICS CTF.

During the 2015 HackMiami Conference, ethical hacker Seth Wahle demonstrated an Android malware deployment method whereby he was able to infect mobile devices through a near field communication microchip implant that had been injected into his hand.

Due to the COVID pandemic and macroeconomic issues of 2020-2022, no annual conference was held and the bi-weekly local meetups migrated to a hybrid format of online and on-site.

The event followed a two-track format: NüWorld0rder for novice hackers learning the fundamentals, and 0ldWorld0rder for advanced researchers presenting their latest projects and vulnerability disclosures.

The 2025 HackMiami Conference is scheduled to take place May 13-17, 2025 in Sunny Isles Beach, FL, Featuring keynote speaker Marco Figueroa a GenAI Bug Bounty SME.
