DeFi data manipulation is too easy — and current oracle solutions aren’t helping much

It seems like every week we hear news of another DeFi project being hacked or exploited. The latest crop of victims includes such projects as Harvest Finance, Akropolis, Value DeFi, Origin and of course Compound. When exploits do occur, they usually involve manipulating the reference price like ETH/DAI on a data source, such as Curve, Kyber or Coinbase Pro. Sometimes, it’s a mistake, as in the SNX case where the Korean Won was quoted with the wrong decimal place. Related: Finance Redefined: You get hacked, they get hacked, everyone gets…

A ‘simple mistake’ exposed 270K crypto wallet buyers

The hacker likely responsible for Ledger’s security breach in July recently dumped a large amount of data exposing the personal information of over 270,000 customers, including phone numbers and physical addresses.

Evolving sectors such as decentralized finance (DeFi) and peer-to-peer transfers introduced new problems.
