In a breach that has hit Indonesia’s crypto community, the centralized exchange Indodax has been hacked, losing over $22 million worth of various tokens in an attack on its hot wallets early Tuesday morning, security researchers confirmed on social media platform X (formerly Twitter).

The stolen assets included more than $14 million in Ethereum (ETH), $2.4 million in Tron (TRX), $1.4 million in Bitcoin (BTC), and $2.5 million in Polygon (MATIC), alongside smaller amounts of other digital tokens. Despite the sizable loss, Arkham Intelligence data revealed that Indodax’s remaining wallet holdings still contained over $400 million in cryptocurrencies at the time of the attack.

Founded in 2014, Indodax has become a prominent centralized exchange catering primarily to the Indonesian market. The platform traded over $11 million worth of cryptocurrencies within the past 24 hours before the attack, offering all tokens against the Indonesian rupiah. However, following the breach, Indodax suspended platform operations, citing “maintenance” on their X account. The announcement has sparked concerns among users, many of whom reported being unable to access their wallet balances, further fueling fears of a wider compromise.

Adding to the confusion, Indodax’s official X account promoted a rupiah “giveaway” on its Instagram page while platform services were paused. This suspicious activity has led to speculation that the exchange’s social media accounts may also have been compromised in the attack.

The exact nature of the attack is still unknown, and Indodax has not released detailed information regarding how the breach occurred. As of Tuesday morning in European time zones, investigations are ongoing, and the platform has yet to confirm whether the stolen funds will be recoverable.

Security Gaps in Centralized Exchanges

This breach serves as a stark reminder of the inherent risks tied to centralized crypto exchanges that fail to maintain up-to-date security protocols. Unlike decentralized exchanges (DEXs), which allow users to control their assets directly, centralized platforms like Indodax act as custodians—meaning they hold and manage users’ digital assets in their own wallets. When a centralized exchange gets hacked, it is the exchange’s infrastructure that is compromised, not the individual investor’s personal wallets.

Security experts have long warned of the vulnerabilities posed by hot wallets—digital wallets connected to the internet that are easier for hackers to access compared to cold wallets, which are stored offline. Centralized exchanges typically keep a portion of their assets in hot wallets for liquidity and operational purposes, but this practice also exposes them to greater risks of cyberattacks.

The Growing Importance of Decentralized Exchanges

The Indodax hack underscores why many in the crypto space are shifting towards decentralized exchanges, which offer greater user control over assets and minimize the risks associated with custodial platforms. Unlike centralized exchanges, DEXs allow users to manage their private keys and execute trades directly from their own wallets, meaning that a hacker would need to breach each individual user’s wallet—an inherently more difficult task.

While major centralized platforms like Binance, Coinbase, and Kraken have built robust security infrastructures to protect user funds, the Indodax breach highlights the dangers that smaller, less secure platforms face in an increasingly hostile digital environment.

For crypto holders, the question remains: How safe are your assets with a centralized exchange? And in the event of a hack, will you be made whole while recovery efforts take place? As the digital asset space continues to evolve, security will remain paramount for both exchanges and users alike.

Looking Ahead

As Indodax works to contain the damage and reassure its users, the broader crypto community is left reflecting on the balance between convenience and control. The incident is likely to reignite debates about the role of centralized versus decentralized exchanges and the best ways to safeguard digital assets in an era where cyber threats are ever-present.

For now, crypto investors must remain vigilant, conducting due diligence and ensuring they are entrusting their assets to platforms with proven track records of security, transparency, and reliability.
