WOO X Halts Withdrawals After $14M Hack

July 25 2025, crypto trading platform WOO X suffered a $14 million security breach, prompting an immediate halt of all withdrawal services to contain the damage.

What Happened in the WOO X Hack

Crypto trading platform WOO X reported on July 25 that several user accounts were compromised, resulting in $14 million in unauthorized withdrawals. According to the team, the exploit was contained quickly, and many of the malicious transfers were blocked before completion.

Nine user accounts were directly affected, and the company has promised to fully compensate all users impacted by the breach. Withdrawals have been paused temporarily for additional safety.

“The incident was quickly detected, and as a precaution, withdrawals were paused. We’ve already contacted the affected users, and all unauthorized withdrawals will be covered,” the WOO X team stated.

Build on Bitcoin Adds ZK-Proofs and Other Exchanges Hit

The WOO X incident is the latest in a wave of crypto exchange hacks that have struck the industry in July. Notably, Build on Bitcoin adds ZK-proofs to strengthen decentralization and mitigate future vulnerabilities. The push for stronger onchain privacy and verification is gaining traction in response to these ongoing exploits.

In the past two weeks:

• June 15: Arcadia Finance suffered a $3.5 million exploit through its Rebalancer contract
• July 16: BigONE exchange was hacked for $27 million via a hot wallet breach
• July 19: Indian exchange CoinDCX lost $44 million due to a server compromise

Crypto Security in 2025: A Mounting Concern

Build on Bitcoin adds ZK-proofs as part of a broader trend to fight back against growing exploits, especially those targeting access control mechanisms. So far in 2025, crypto hacks have caused over $3.1 billion in losses globally.

In response, some exchanges like CoinDCX are launching White Hat bounty programs, offering up to 25% of funds recovered by ethical hackers and security firms.

As vulnerabilities persist, the focus on decentralization and verifiable computation has never been stronger. Build on Bitcoin adds ZK-proofs to support this shift toward a more secure crypto infrastructure.
