Jon DiMaggio, Founder and Principal Researcher of Arkem Cyber

Intelligence, not noise

Arkem Cyber is an independent advisory firm focused on the people behind cybercrime: ransomware crews, data-extortion groups, and the criminal economy that supports them. We turn primary-source research into clear, decision-ready guidance for executives, boards, and the advisors who support them.

Where we help

  • Strategic threat intelligence — Who is targeting your sector, how they operate, and what actually reduces your exposure.
  • Ransomware actor expertise — Current, in-depth knowledge of major ransomware and extortion groups: how they breach, how they pressure victims, and how they negotiate.
  • Executive & board advisory — Plain-language briefings that help leadership weigh risk and make decisions they can stand behind.
  • Incident decision support — An independent vantage point during an active incident, focused on the strategic choices that fall to leadership.
  • Research partnerships — Rigorous, source-backed collaboration with security teams, journalists, and research institutions.

How we work

Small, senior, and independent. Every conclusion traces back to evidence. We don’t sell tools, staff your team, negotiate on your behalf, or run your security program — we give you the intelligence and judgment to steer it.
