On July 19, 2025, India's prominent cryptocurrency exchange CoinDCX fell victim to a sophisticated cyberattack, resulting in the theft of approximately βΉ380 crore (around $44 million) from an internal operational wallet. The incident, confirmed by the company over the subsequent days, highlighted vulnerabilities in the crypto sector amid a surge in global hacks. While customer funds remained untouched, the breach led to temporary suspensions of certain trading pairs and withdrawals, sparking concerns over platform security. This event echoes the 2024 WazirX hack, underscoring the escalating risks in India's burgeoning crypto market. Below, we delve into the details of the attack, its execution, CoinDCX's response, and broader implications for the industry.
The hack unfolded on July 19, 2025, targeting a liquidity wallet managed through a third-party platform, which was compromised via server-side vulnerabilities. Initial reports surfaced through on-chain analysis by blockchain sleuths, revealing outflows of over $44.2 million in various cryptocurrencies, including assets on Solana, which were subsequently bridged to Ethereum. CoinDCX CEO Sumit Gupta publicly acknowledged the breach on July 21, emphasizing that the loss represented about 7.6% of the exchange's internal treasury but did not impact user holdings, which are secured in cold wallets.By July 22, the company had resumed normal operations for most services, though some trading pairs experienced disruptions as a precautionary measure. No ransom demands were reported, and the attackers employed obfuscation tools like Tornado Cash to launder the stolen funds, complicating recovery efforts. The incident triggered over 31,000 withdrawal requests in the following 24 hours, reflecting heightened user anxiety.
Investigations point to a targeted server-side exploit, potentially orchestrated by the North Korean-linked Lazarus Group, known for similar high-profile crypto heists. The attackers drained an internal account used for liquidity provision, exploiting flaws in the wallet's integration with external services. This method aligns with Lazarus's tactics, including the use of advanced persistent threats (APTs) to infiltrate supply chains and bypass security controls.Unlike broad phishing campaigns, this breach involved precise reconnaissance and execution, possibly through compromised credentials or unpatched vulnerabilities in the third-party infrastructure. Blockchain analytics firms like Chainalysis have noted that such attacks contribute to 2025 being on pace for record crypto thefts, with over $1 billion already lost globally this year.
In a proactive move, CoinDCX announced India's largest crypto recovery bounty on July 21, offering up to 25% of recovered fundsβpotentially $11 millionβto ethical hackers, blockchain investigators, and white-hat researchers who assist in tracing and retrieving the assets. The company has collaborated with global security teams, law enforcement agencies, and on-chain trackers to pursue the perpetrators.CEO Sumit Gupta reiterated the exchange's financial stability, covering the losses entirely from internal reserves without affecting operations or user withdrawals. Security enhancements, including a full audit of wallet integrations and reinforced protocols, were implemented post-breach. Despite initial delays in communicationβtaking about 17 hours to address user complaintsβCoinDCX maintained transparency through updates on X and its blog.
This hack amplifies concerns over the security of centralized exchanges (CEXs), particularly in emerging markets like India, where regulatory frameworks are still evolving. With 2025 projected to surpass previous years in crypto losses, driven by state-sponsored actors like Lazarus, the incident underscores the need for decentralized alternatives and stricter supply chain audits.Broader ramifications include eroded investor confidence, as evidenced by the spike in withdrawals, and calls for enhanced cyber resilience. Experts, including those from The CyberDiplomat initiative, highlight this as part of a global trend involving APTs and supply chain attacks, urging international cooperation. For users, it serves as a reminder to diversify holdings, use hardware wallets, and enable multi-factor authentication.As crypto adoption grows, incidents like the CoinDCX breach emphasize that robust security isn't optionalβit's essential. CoinDCX's bounty program sets a precedent for community-driven recovery, but preventing such exploits requires ongoing vigilance and innovation in the face of evolving threats.
