\Hackers pulled off a $540-million cryptocurrency heist by exploiting Ronin Network software that lets players of the online game "Axie Infinity" transfer digital assets across blockchains.
Ronin developer Sky Mavis said the hackers used a social engineering exploit to acquire the five keys needed to access Axie Infinity's underlying bridge.
Blockchain analytics firm Elliptic estimates that decentralized financial systems saw at least $10.5 billion in losses last year due to crime, including stolen funds and falling prices in cryptocurrency offered by hacked systems.
Blockchain experts said with cross-chain projects attracting capital and energy, security tools are under pressure to keep up.
