Unseen Money 12: Keeping hackers out of your DeFi wallet

June 09, 2025

The decentralised finance (DeFi) market is booming—but the world’s best hackers are on a constant look-out for ways to steal your crypto tokens.


North Korea, which recently committed the largest theft in cryptocurrency history, is probably top of the hackers’ game.


What do crypto users need to know about the risks in this unregulated but fast-growing market?


In the latest episode of Unseen Money from New Money Review, Timur Yunusov and Paul Amery are joined by Arseny Reutov, chief technology officer at Decurity, a security audit and ethical hacking firm specialising in DeFi.


During the podcast, we discuss:


  • Malware, ethereum and the recent $1.5bn Bybit hack
  • State-of-the-art techniques in DeFi hacks
  • Mixers, cross-chain bridges and the laundering of stolen funds
  • How North Korea became the world leader in crypto hacks
  • Ways of detecting flaws in DeFi smart contracts
  • Who audits DeFi?
  • Incentives to report, rather than exploit smart contract flaws
  • Is DeFi security improving?
