Hackers norcoreanos lavan una cantidad récord de 640 millones de dólares provenientes de Binance, a través de 12.000 carteras criptográficas en 11 redes: Elliptic.

Los hackers norcoreanos responsables del robo de Binance la semana pasada, que alcanzó la cifra récord de 6.400 millones de dólares, están lavando activos criptográficos a través de una nueva cartera aproximadamente cada 25 segundos, según la empresa de análisis de blockchains Elliptic.

Elliptic señala en un nuevo análisis que el proceso de lavado de dinero es “claramente automatizado”, utilizando 40.000 transacciones, 12.000 carteras y 11 blockchains diferentes en menos de cuatro días.

“La mayor parte del dinero lavado hasta ahora ha pasado por Tron, donde los fondos se dividieron en unas 7.700 direcciones y luego se transfirieron a Ethereum. Desde el 1 de noviembre, ETH, SOL, NEAR y XRP han comenzado a moverse. Por primera vez, parte del dinero robado se ha mezclado. Desde el 1 de noviembre, alrededor de 28 BTC (2.2 millones de dólares) han sido transferidos mediante técnicas de coinjoins al estilo Wasabi.”

Tom Robinson, científico jefe y cofundador de Elliptic, indica que 3.460 millones de dólares del dinero criptográfico robado estaban en forma de monedas estables como USDT y USDC, las cuales pueden ser congeladas por sus emisores. Por eso, para los hackers fue prioritario convertir esas monedas estables en activos como Ethereum (ETH) y Tron (TRX).

“En Ethereum, Tether congeló los USDT robados 37 minutos después de que llegaran. Antes del congelamiento, el atacante logró intercambiar 434 millones de USDT por ETH en exchanges descentralizados (DEX) como Uniswap. También solicitó prestados 19.762 ETH a través del protocolo de préstamos Aave, utilizando como garantía otros 59.9 millones de USDT. En Tron, intercambió 234 millones de USDT por TRX en SunSwap, antes de que Tether congelara el resto.”El “círculo” congeló los 823 millones de USDC robados antes de que ninguno de ellos pudiera ser intercambiado.

En total, se han congelado o incautado 2850 millones de dólares. Alrededor de 786 millones de monedas estables (stablecoins) fueron convertidas antes de que se aplicaran las medidas de congelación.

La empresa de análisis Chainalysis atribuye este ataque sin precedentes al grupo de ciberdelincuencia norcoreano TraderTraitor, que se cree opera bajo la égida de la organización de hacking patrocinada por el estado conocida como Lazarus Group.
