And the services that are coalescing to form the backbone of this new financial ecosystem are experiencing a trial by fire as the cryptocurrency gold rush plays out. There is nothing to suggest that social engineering-based exploits are becoming more popular, though the success of the Ronin incident has the potential to inspire other hackers.”Ĭryptocurrency platforms, and the decentralized finance movement in general, have been plagued by security issues as the underpinning technologies evolve and mature.

“They have, however, been observed comparatively less often than code exploits. “Social engineering and associated private key compromises have always been a vector of attack on DeFi platforms in general, not just bridges,“ says Arda Akartuna, a cryptocurrency threat analyst at the blockchain analytics and compliance firm Elliptic. But social engineering to take over privileged target accounts is also a classic attacker strategy that has been used widely, including in decentralized finance.

In particular, other attacks have targeted bugs in how bridges implement “smart contracts,” little blockchain programs that are designed to run at certain times under specific conditions-essentially, a contract that executes itself.

The Ronin breach may represent an evolution of bridge hacks, given that it focused on a traditional social engineering attack and exploited security design issues rather than a specific software vulnerability, as in most other bridge hacks. “The hack went unnoticed for several days, which implies the team did not have basic monitoring of their system-standard security practices would have automatic email and SMS alerts for abnormal events or large movements of funds.” “This hack is so concerning because it appears that the team failed to follow well-known basic security practices,” Prestwich says. In all of these attacks, hackers exploited software vulnerabilities to drain funds, but the Ronin Bridge attack had a different weak point. Memorably, the Poly Network bridge had about $611 million worth of cryptocurrency stolen last August, before the attacker gave the funds back a few days later. In addition to the Ronin heist, attackers stole about $80 million worth of cryptocurrency from Qubit Bridge at the end of January, roughly $320 million worth from Wormhole Bridge at the beginning of February, and $4.2 million worth days later from Meter.io Bridge. Bridges are new enough that there are very few experts.” Over time, we'll professionalize, develop best practices, and there will be more people capable of building and analyzing bridge code. “Bridges will continue to grow because people will always want the opportunity to join new ecosystems. “Any capital on-chain is subject to attack 24/7/365, so bridges will always be a popular target,” says James Prestwich, who studies and develops cross-chain communication protocols. Bridges need a reserve of cryptocurrency coins to underwrite all those wrapped coins, and that trove is a major target for hackers. It's like a gift card or a check that represents stored value in a flexible alternative format. So if you go to a bridge to use another currency, like Bitcoin (BTC), the bridge will spit out wrapped bitcoins (WBTC). Cryptocurrencies are typically siloed and can't interoperate-you can't do a transaction on the Bitcoin blockchain using Dogecoins-so “bridges” have become a crucial mechanism, almost a missing link, in the cryptocurrency economy.īridge services “wrap” cryptocurrency to convert one type of coin into another. Successful attacks on “blockchain bridges” have become increasingly common over the past couple of years, and the situation with Ronin is a prominent reminder of the urgency of the problem.īlockchain bridges, also known as network bridges, are applications that allow people to move digital assets from one blockchain to another.

The incident, which is one of the biggest heists in the history of cryptocurrency, specifically siphoned funds from a service known as the Ronin Bridge. This week, the cryptocurrency network Ronin disclosed a breach in which attackers made off with $540 million worth of Ethereum and USDC stablecoin.
