Cybercriminals have accelerated their shift away from crypto mixers for cross-chain bridges over the previous yr, based on blockchain forensics agency Elliptic.
In June and July, almost all the crypto stolen was laundered via cross-chain bridges, Elliptic’s knowledge exhibits a whole reversal from the primary half of 2022.
In a Sept. 18 weblog submit, Elliptic defined the cross-chain crime development is because of the “crime displacement” impact — the place criminals transfer to a brand new methodology to hold out the illicit exercise when the prevailing methodology will get over-policed. Nevertheless, the shift to cross-chain bridges is rising forward of their projections.
Between July and September 2022, the ratio of laundered funds passing via mixers vs. cross-chain bridges flipped, similar to the U.S. Workplace of International Asset Management’s sanctioning of Twister Money in August 2022, mentioned the agency.
Elliptic mentioned many cybercriminals, just like the North Korean-backed Lazarus Group, flocked to the Avalanche bridge after the sanctions.
This similar bridge was reportedly used just lately by the Lazarus Group to facilitate a number of the stolen funds in Stake’s $41 million exploit on Sept. 4, based on blockchain safety agency CertiK.
Crypto mixers noticed a small comeback between November 2022 and January 2023, because of the shutdown of RenBridge — which closed in December after its financer, Alameda Analysis collapsed from FTX’s chapter.
Elliptic estimates that RenBridge facilitated $500 million in laundered funds all through its operation.
Nevertheless, shortly after, criminals have moved again to cross-chain bridges once more, much more than earlier than.
Chain-hopping through bridges has change into one of the vital widespread cash laundering strategies for illicit actors. That is been an issue for crypto investigators — till now.

Elliptic mentioned that criminals could also be preferring cross-chain bridges as it’s tough for blockchain forensic companies to trace illicit exercise throughout chains in a scalable method.
“Criminals are conscious that legacy blockchain analytics options would not have the means to hint illicit blockchain exercise throughout blockchains or tokens in a programmatic or scalable method.”
As well as, many of those stolen tokens are solely exchangeable via cross-chain bridges, whereas most of those DeFi companies don’t require identification verification to make use of, Elliptic defined.
The agency estimates that $4 billion in illicit or high-risk cryptocurrencies have been laundered via cross-chain bridges since 2020.
