• Woo X suspended withdrawals after a $14 million security breach affected nine user accounts.
• BigONE and CoinDCX also suffered major hacks in July, losing $27 million and $44 million, respectively.
• Crypto-related hacks have exceeded $3.1 billion in 2025, with access control exploits being the most common attack vector.

Woo X, a digital asset trading platform, temporarily paused its withdrawal services on Thursday following a security breach. The platform confirmed that nine user accounts were compromised, resulting in unauthorized fund transfers totaling approximately $14 million. The company reported that the exploit was quickly identified, and immediate steps were taken to block further withdrawals.

According to an official update posted on X, formerly Twitter, Woo X stated that the affected users had already been contacted. The company further added that it would fully reimburse all losses tied to the unauthorized transactions. 

Withdrawal services were paused as a security measure during the investigation and containment process. Woo X has not issued further public details about the breach’s origin or technical vulnerabilities.

Multiple Crypto Platforms Breached in July

The Woo X incident marks one of several major security breaches involving crypto platforms in July. At least three separate exchanges have reported significant losses due to hacks during the second half of the month.

On July 16, crypto exchange BigONE experienced a $27 million loss after a hot wallet was compromised. According to a security notice from BigONE, an external party gained access to the wallet, resulting in unauthorized fund transfers. The platform attributed the breach to a third-party attack and said the affected systems have since been isolated.

Just three days later, on July 19, Indian crypto platform CoinDCX confirmed it had lost $44 million. The breach involved an internal account used to provide liquidity. CoinDCX clarified that no user funds were affected. In response, the platform launched a White Hat recovery initiative, offering ethical hackers up to 25% of the retrieved funds.

DeFi Platform Arcadia Finance Also Targeted

In a separate case, Arcadia Finance, a decentralized finance platform, suffered a $3.5 million loss in mid-June. Attackers reportedly exploited Arcadia’s Rebalancer smart contract to drain funds. Details of the vulnerability were disclosed in a security analysis shared by blockchain investigators.

These incidents bring total crypto-related losses to over $3.1 billion in 2025 so far. The majority of the attacks this year have involved access control exploits, based on data provided by cybersecurity firm Hacken.

Exchanges Respond to Ongoing Threats

Following the recent breaches, platforms have implemented emergency protocols, paused transactions, and engaged security experts. CoinDCX’s bug bounty initiative is the latest example of steps being taken to trace and recover stolen assets.

While Woo X confirmed that it had stopped additional withdrawals during the incident, no official statement has been made on the timeline for restoring full services. Cointelegraph attempted to contact Woo X, but no response was received by the time of publication.
