According to reports from Yonhap News, the South Korean virtual asset trading platform Prabang has announced a temporary service suspension due to a hacker attack that resulted in an asset loss of approximately 100 million Korean Won, stating that it will fully compensate the affected funds with the company's own assets.According to industry sources, Prabang discovered abnormal transfers from its hot wallet on October 24 and immediately initiated an emergency response and comprehensive investigation, during which a security vulnerability was found. After confirming unauthorized external access on October 26, the platform reported the incident to relevant authorities and continues to investigate the cause and extent of the losses.Yonhap News stated that there have been a series of hacker-related incidents in the financial and virtual asset industry recently, with this being the first confirmed case of asset loss. The report mentioned that this incident appears to be different from the Prabang-related incident mentioned by financial authorities in the AI hacker intrusion inspection results on October 14. Additionally, on October 27, Bithumb experienced a hacker attack targeting its internal systems, leading to the leakage of employee personal information. On the same day, several Korean Won trading platforms also faced intrusion attempts targeting personal information and assets.

Web3 infrastructure and payment network Diamante announced that its ecosystem has experienced a security breach involving unauthorized activities by malicious actors. Upon discovery, the team immediately activated emergency security protocols and coordinated with exchange partners, market makers, liquidity providers, and listing partners to suspend affected withdrawals and transfers, restrict unauthorized asset movement, and prevent further exploitation.Diamante stated that the investigation has identified the suspected attackers and is coordinating with law enforcement agencies, government entities, and jurisdictional partners in multiple countries to seek legal action and asset recovery. A comprehensive incident review has been initiated to determine the cause of the breach, the sequence of events, the scope of affected assets, and to strengthen the infrastructure. Diamante is committed to ensuring that every affected participant is fully compensated and will continue to update the incident scope, asset recovery progress, and protective measures upon obtaining verified information.

Muneeb Ali, co-founder of the Bitcoin Layer2 network Stacks, stated in Cointelegraph's Chain Reaction podcast that concerns surrounding quantum computing are suppressing institutional funds from entering Bitcoin, and the network needs a credible security upgrade roadmap to restore investor confidence. He mentioned, "Quantum concerns have set a ceiling on Bitcoin's growth," believing that this uncertainty may lead risk-averse institutional investors to delay large purchases until developers provide a clear path to quantum resistance. Stacks is a Bitcoin Layer2 network aimed at introducing smart contracts and decentralized applications to Bitcoin, and Ali is a co-founder of the project.Ali warned that if developers fail to make substantial progress in quantum resistance by 2028, Bitcoin could enter a riskier phase. He pointed out that upgrades typically take years to implement, and users will need additional time to migrate their assets to new addresses. Citing guidance from the National Institute of Standards and Technology (NIST), he views 2030 as a target node for transitioning to quantum resistance and believes advancements in artificial intelligence could accelerate the development of quantum computers, potentially moving this timeline up to 2029.Ali acknowledged that some Bitcoin supporters believe the quantum threat is distant and that concerns are exaggerated, but he thinks that the very disagreement over the urgency of the threat, in the absence of a credible upgrade roadmap, will undermine investor confidence. He also stated that sufficiently powerful quantum computers are more likely to emerge from large research laboratories rather than unknown attackers, and companies like Google and Microsoft lack the motivation to steal Bitcoin, but the quantum security threat will impact the entire crypto industry, "If Bitcoin is hit, all downstream projects will be affected." Currently, developers are exploring protective solutions, with StarkWare stating in September that researchers reduced the computational cost of preparing an experimental quantum-resistant Bitcoin transaction by 79% after a week of optimization challenges. This solution does not require modifications to Bitcoin's consensus rules, but the cost reduction has only been validated in benchmark tests.

Bitcoin security expert Jameson Lopp stated that cyber attacks are growing along an "exponential" path. He pointed out that the number of vulnerabilities discovered in the past two and a half months has increased exponentially, with attackers being the first to adopt unreviewed AI models, and security researchers "failing to get adequate rest."Lopp explained that Bitcoin Core has adjusted its security policies because AI can discover vulnerabilities through simple prompts; security measures need to shift from annual audits to real-time defenses and be embedded in the development process. He also analyzed a PHP remote code execution vulnerability, believing the actual impact to be less than expected.Additionally, Lopp mentioned that Google's estimate of 500,000 quantum bits involves the difference between physical quantum bits and logical quantum bits; if the quantum threat time window is less than ten years, the industry will be at a disadvantage. Currently, there are only a few hundred available quantum bits, and quantum upgrades will take years due to Taproot, consensus rules, and untested cryptography. About 30% of addresses have exposed public keys, and attackers will prioritize targeting these addresses; unpatchable hardware issues and "wrench attacks" have exceeded 700 cases.
