In this LABScon 25 talk, Andrew MacPherson dives deep into the high-stakes world of crypto crime, which has amassed approximately $9 billion in illicit funds. Andrew demystifies the technical landscape and exposes the sophisticated attack vectors plaguing the decentralized finance (DeFi) space.
The talk begins with an explanation of the core concepts necessary to understand crypto-related security threats, including definitions of blockchains, wallets, and smart contracts. Andrew explains that a key point in the architectural difference of many crypto applications is that they typically rely solely on frontends, with all interactions happening in the browser via the wallet extension.
The talk then moves on to focus on attack patterns. Crypto thieves target every weak point, from applications and code to the developers and executives themselves. The speaker details the largest crypto heist to date, the $1.5 billion loss from Bybit. This attack involved infecting a developer’s machine, gaining access to production JavaScript code, and modifying it to authorize a full wallet drain during a multi-signature transaction. The talk also covers supply chain risks like typo-squatting, exploitation of personal servers like Plex to compromise GitHub accounts, and the rise of “drainers as a service” that simplify crypto theft.
Andrew also covers the challenges attackers face in laundering stolen funds, and how they leverage techniques such as cross-chain swaps, using mixers like Tornado Cash, and non-KYC platforms for conversion to cash. Despite the fact that all blockchain logs are public and permanent, the presentation also discusses the challenges threat intel analysts face in tracking these rapidly moving funds.
Andrew’s presentation is essential viewing for anyone interested in cryptocurrency and cybersecurity, especially those looking to understand the technical realities of financial crime in the decentralized era.
