Dunamu CEO Oh Kyung-seok stated that the popularization of AI, stablecoins, and tokenization will profoundly change the way finance and commerce operate.

The Central Bank of Brazil has developed a real-time warning system for cryptocurrency threats and has collaborated with the digital asset threat protection company Hypernative to provide attack identification, response, and fund tracking support to banks and domestic cryptocurrency exchanges. In July 2025, cybercriminals exploited a software vulnerability in the financial software middleware company C&M to steal $180 million from the financial system and exchanged part of the funds for Bitcoin and USDT through exchanges.This incident has prompted the Central Bank of Brazil to accelerate the construction of related systems. Regina Pedroso, Executive Director of the Brazilian Tokenization Association, stated that the system will begin integration in the next two weeks, with Foxbit and Mercado Bitcoin participating in the implementation. Relevant agencies have completed testing and issued some warnings, and Brazil will also implement a 24-hour preventive hold on cryptocurrency transfers exceeding $10,000 per transaction or per day for individuals.

The security team of the open-source wallet provider OneKey successfully replicated the exploitation of a vulnerability in the old version of the Ledger Ethereum application in a laboratory environment. OneKey's founder and CEO Wang Yishi stated that they executed a "transaction replacement attack" on Ledger Ethereum application version 1.22.1 by exploiting a previously patched vulnerability, allowing attackers to overwrite pending transactions while users review legitimate transactions.Ledger responded that exploiting this vulnerability requires controlling the communication between the device and the host, such as through malware, compromised wallet software, or malicious web pages. Ledger has added application layer protections in the Ethereum application version 1.22.2 released on August 13 and fixed the underlying issue in Secure SDK 26.6.1 on August 21. Ledger emphasized that no users were hacked as a result; this was merely a replication of the vulnerability in a laboratory environment.This security test occurred after the Coldcard vulnerability incident. Previously, the Coldcard wallet had a firmware vulnerability that posed security risks to some mnemonic phrase generation, but Ledger stated that its devices were not affected by this vulnerability because recovery phrases are generated by a certified random source built into the device's secure chip. The vulnerability replicated by OneKey is unrelated to mnemonic phrase generation but affects the way transactions are processed during the signing process.
