Shiba Inu’s core growth workforce is escalating its response to the Shibarium bridge exploit after a brand new on-chain investigation mapped the hacker’s Twister Money laundering path to KuCoin deposit accounts. Reacting to on-chain sleuth Shima (@MRShimamoto) on X, core developer Kaal Dhairya wrote “Nice work! This must be amplified. I will even guarantee it’s despatched to the FBI connected to the open investigation report and request Kucoin to cooperate.”
Shiba Inu Sleuth Exposes Shibarium Hacker
The Shibarium bridge was exploited in mid-September in an assault estimated at round $2.3–$2.4 million, after the perpetrator seized a super-majority of validator keys and withdrew property together with ETH, SHIB and KNINE. K9 Finance DAO, Shibarium’s liquid-staking companion, launched a bounty course of that began at 5 ETH, later superior to a 20 ETH smart-contract supply and in the end to a last 25 ETH proposal endorsed instantly by the Shiba Inu workforce. The exploiter by no means accepted, and K9 Finance has since confirmed that the unclaimed ETH within the bounty contract has been returned to contributors, with Shib.io receiving again 20 ETH.
In an in depth 1 December thread, Shima mentioned the “Shibarium Bridge hacker foolishly selected to not settle for the K9 bounty – it’s lastly time to share the investigation we’ve been engaged on,” describing months of tracing that concerned hundreds of transactions and 111 wallets. His reconstruction exhibits 260 ETH flowing from exploit-linked wallets into Twister Money, with 232.49 ETH in the end reaching KuCoin by means of 48 deposits into 45 distinctive KuCoin deposit addresses, which he believes are largely operated by cash mules slightly than the hacker instantly.
In response to his write-up and an accompanying MetaSleuth dashboard, the path begins with the unique exploit tackle and 9 “dumping” wallets. These wallets obtained the stolen tokens, liquidated them progressively for ETH over roughly every week, and despatched a complete of 260 ETH into Twister Money. Of that quantity, 250 ETH entered the mixer’s 10-ETH pool and 10 ETH the 1-ETH pool in an try to interrupt on-chain linkability between the hack and any later withdrawals.
The essential breakthrough, Shima says, took place forty days after the exploit. A pockets already tied to the hacker cluster despatched precisely 0.0874 ETH to what was meant to be a clear Twister withdrawal pockets. That minor top-up, he describes as “one silly mistake” that “fully unravelled their Twister Money laundering,” as a result of it established a direct on-chain connection between the exploit facet of the graph and a supposedly nameless post-mixer tackle. From that contaminated node he was capable of work outward, clustering a number of Twister withdrawal wallets, intermediaries and last KuCoin “funnel” wallets.
Shima experiences that every funnel pockets sometimes routes funds to 2 KuCoin deposit addresses, making a last cluster of 45 KuCoin endpoints and roughly two dozen depositors that he argues could be handled as money-mule cash-out accounts. He says the complete tackle checklist, transaction graph and methodology had been first shared privately with the Shibarium workforce so they may strategy legislation enforcement and KuCoin whereas any funds remained inside attain. Nevertheless, he recounts that KuCoin’s fraud desk insisted on receiving a proper law-enforcement case quantity earlier than performing on the proof.
The official ShibariumNet X account has now publicly backed the analysis: “Due to @MRShimamoto for doing all of the onerous work right here to compile this thread. We actually respect your diligence and methodical strategy. Hopefully this investigation can proceed with the assistance of the correct authorities. The communities want solutions.”
