Title: BigONE Hacked: $27M Stolen in Devastating Hot Wallet Attack
BigONE, a well-established crypto exchange, has recently announced a devastating hot wallet attack, resulting in the loss of an astonishing $27 million. This significant breach serves as a stark reminder of the ongoing threats that centralized exchanges still face.
According to reports, BigONE’s real-time monitoring system detected unusual asset movements on July 16, triggering an immediate investigation into the incident. After conducting a thorough examination, it has been confirmed that an attacker breached the exchange’s production servers, bypassing risk checks and making off with the aforementioned sum of $27 million.
The scope of this heist is quite extensive, involving the theft of 120 Bitcoin, over 350 Ether, millions in Tether (USDT), as well as a variety of other tokens like SHIB and CELR. Despite this colossal loss, BigONE has assured users that its private keys remain secure and will fully compensate affected customers.
Experts from Cyvers and Hacken have suggested that the attack likely originated from weaknesses in BigONE’s Continuous Integration and Deployment pipelines, combined with inadequate network segmentation between servers. The hackers deployed malicious binaries to gain unauthorized access, subsequently consolidating stolen assets into fresh wallets for laundering purposes.
This incident serves as a potent reminder of the imperative need for stronger CI/CD protections and automatic incident response systems to swiftly contain damage. As losses across the sector have already surpassed $2.4 billion in the first half of 2025, this event underscores the pressing requirement for improved security measures by centralized platforms.
On a more positive note, decentralized self-custody and peer-to-peer infrastructure continue to be at the core of the industry’s trust foundation, even as centralized actors confront breaches.
