The U.S. Secret Service recovered over $25 million in cryptocurrency through five investigations

According to Bitcoin.com, the U.S. Attorney's Office for the District of Columbia and the U.S. Secret Service Washington Field Office announced that a cyber fraud task force has seized over $25 million in cryptocurrency as part of multiple investigations related to international fraud schemes targeting residents of the United States and Canada. The U.S. Attorney for the District of Columbia has filed five civil forfeiture complaints seeking the forfeiture of the recovered cryptocurrency.Investigators have confirmed multiple money laundering networks and thousands of victims globally, with the largest complaint involving a romance scam affecting over 200 victims, totaling approximately $12.1 million. Another complaint involves a network of suspicious cryptocurrency wallets reported by Canadian authorities to the U.S. Secret Service, amounting to about $10.4 million.Agents tracked over 270 suspected victim transactions related to fraudulent investment platforms, with these two cases accounting for approximately 85% of the assets involved in the five forfeiture complaints. The remaining cases involve blocked withdrawals, fake investment accounts, and recovery of fraud. Investigators stated that most suspected money launderers are located in Southeast Asia and identified internet protocol addresses associated with China, Malaysia, and Cambodia; the five investigations are still ongoing.

Secret Network lost 4.67 million dollars due to a cross-chain vulnerability, and the attack went undetected for seven days

The blockchain research organization Common Prefix disclosed that on June 10, hackers exploited a vulnerability in the Secret Network and Axelar cross-chain bridge contract to forge deposits and mint uncollateralized tokens, subsequently cashing out approximately $4.67 million.The attack went undetected for seven days until a normal cross-chain transfer failed due to insufficient funds in the escrow account on June 17, revealing the anomaly. The root of the vulnerability lies in the fact that when the contract changed from an escrow model to a minting model, it deleted two key functions responsible for verifying the source of transfers, and it had never undergone an external audit since its deployment in early 2023. Secret Network pointed out that the Axelar bridging infrastructure failed to trigger any effective anomaly monitoring or emergency pause mechanism before the assets were stolen on a large scale.The stolen funds were routed through Osmosis to Ethereum and exchanged for ETH on CoW Protocol, then dispersed into exchanges such as KuCoin, ChangeNow, and HitBTC. Currently, approximately $672,000 remains in the attackers' Axelar wallet. Secret Network has requested Axelar to freeze that address, but the request was denied. Axelar emphasized that its core protocol was never affected, and the exploited contract was not developed or maintained by Axelar. Currently, Axelar has disabled the related cross-chain connections and stated that it is coordinating follow-up actions with exchanges and law enforcement agencies.
