Elliptic said in a blog post, “At least $267.2 million (approximately Rs 2,122 crore) of crypto assets stolen from exchanges and decentralized finance (DeFi) services have been laundered through Rainbridge over the past two years.” Rainbridge Russia It is also an important facilitator for ransomware gangs linked to the U.S., through which ransoms of over $153 million (about Rs 1,215 crore) have been paid to date.”
Earlier this month, Nomad, a cross-chain bridge, suffered a loss of $200 million (about Rs 1,570 crore) in a protocol breach.
In its report, Elliptic stated that $2.4 million (about Rs 20 crore) in crypto assets stolen from Nomad has also been routed through RenBridge.
Decentralized cross-chain bridges such as Rainbridge provide an unregulated option for exchanges to transfer value between blockchains and are therefore a challenge. Transactions on these cross-chain bridges are processed by a network of thousands of false-name validators, known as “darknodes”.
Hackers and scammers take advantage of these bridges by depositing their tokens from one chain into bridges and then withdrawing the equivalent of parallel tokens on another chain.
In early July, the Financial Action Task Force (FATF) published a special report that highlighted a growing number of cases showing the misuse of DeFi tools such as cross-chain bridges.
