What’s new? According to an anonymous researcher under the nickname ZachXBT, known for his publications about hacks and scams in the crypto space, Taiwanese crypto exchange BitoPro suffered an exploit with $11,5 million in damage on May 8.

What else is known? ZachXBT reported in its Telegram channel that suspicious outflows were reported from the exchange’s hot wallets on several networks, including Tron, Ethereum, Solana, and Polygon.

The stolen funds were then transferred to the Tornado Cash crypto mixer or redirected to the Bitcoin blockchain via the Thorchain protocol and transferred to the Wasabi wallet, which also offers mixing capabilities.

Although 25 days have passed since the incident, BitoPro did not publish an official statement regarding the incident until ZachXBT wrote about it.

When users of the exchange shared ZachXBT’s post on BitoPro’s official Telegram channel, its admin wrote, “Just received numerous inquiries, and we will respond uniformly to all of you later.”

BitoPro then issued an official statement in Chinese, admitting that the platform had been hacked during an update to its wallet system and asset transfer operations.

“At the moment the incident occurred, an emergency response mechanism was immediately activated, securely transferring platform assets to a new wallet and blocking hacker activities, while also commissioning a third-party professional cybersecurity company to comprehensively investigate and track related leads,” BitoPro said in its translated statement.

While the company assured that no user funds were affected, it did not explain why it did not promptly report the security breach. Official details about the exploit remain undisclosed.

The $1,5 billion hack of Dubai-based exchange Bybit by Beng Zhou in February also involved laundering assets through mixers including Wasabi, Tornado Cash, and Thorchain, which were then exchanged via cross-chain bridges and P2P platforms.

According to the latest update from the head of Bybit, more than 27% of the stolen funds, or about $380 million in cryptocurrency, are unrecoverable. The hackers behind the exploit have been identified as Lazarus Group, which is backed by North Korea.
