Hacken, which searches for vulnerabilities in DeFi, NFT, and blockchain applications and produces security reports, itself encountered a major cybersecurity vulnerability that affected the mining of its HAI tokens on the Ethereum and BNB Chain networks. This led to a 98% collapse in the value of HAI.
This was reported by The Crypto Times, which notes that a hacker who exploited the Hacken vulnerability managed to sell tokens worth over $250,000.
The company acknowledged the problem and said they were working on an investigation.
«We are investigating an incident involving unauthorized mining of HAI tokens on Ethereum and BNB Chain, caused by a compromised private key associated with the bridge deployment. As a precautionary measure, the ETHVET and BSCVET bridges have been temporarily suspended. If you have HAI on the Ethereum or BNB chain, please do not initiate transactions through the bridge until further notice», — Hacken said.
The company later stated that it did not consider the situation a security breach, but considered it a «human error» during architectural changes.
The recent $HAI security incident was not a hack, but a human error during architectural changes.

A recap of the AMA with @buda_kyiv clarifying the details, what we know now, and how we’re moving forward 👇
«The private key of the miner account (ETH and BNB) was compromised, which led to unauthorized mining of HAI and a drain on BSC DEX. One big misunderstanding: the developer’s wallet was NOT compromised. This is what allowed us to withdraw the compromised miners from the $HAI contract,» Hacken later noted.
The company claims that the core infrastructure has always been separate from $HAI and remains secure.
«I will never forget this night. Yes, we have problems. It was and is painful and stressful. But we are HAI. This is a moment of growth, and I am grateful for this challenge,» Hacken co-founder and CEO Dmitry Budorin commented on the incident.
As Incrypted notes, on June 21, 2025, the HAI token collapsed by almost 98% immediately after the first reports of the Hacken attack appeared.
«The price drop is the biggest blow in the short term. It is not a issue in the long term,» Budorin believes.
Previously, the Iranian cryptocurrency exchange Nobitex was hacked, causing losses of almost $82 million. The Gonjeshke Darande group, which is linked to Israel, claimed responsibility for the hack.
