A hacker walked away with $25 million from quantitative trading firm Kronos Research after accessing its compromised API keys.

On Nov. 19, Kronos Research  revealed that an unauthorized entity accessed some of its API keys. Subsequently, the firm stopped its trading services on the platform. However, no losses were reported at the time.

In the interest of transparency
Around 4 hours ago, we experienced unauthorized access of some of our API keys. We paused all trading while we conduct an investigation. Potential losses are not a significant portion of our equity and we aim to resume trading as soon as possible.

Blockchain investigator ZachXBT followed up on the announcement and found roughly $25 million in total was siphoned away into six unique crypto wallet addresses. According to the investigation, the six transactions — worth 2,780 Ether ( ETH ), 2,540 ETH, 2,540 ETH, 2,636 ETH, 4.93 ETH and 2,507.52 ETH, respectively — were made from a Kronos Research account to various addresses owned by the hacker.

While Kronos Research is indefinitely halting the trading services until internal investigations track down the culprit who stole over 12,800 ETH, the firm expects a positive outcome:

“Potential losses are not a significant portion of our equity and we aim to resume trading as soon as possible.”

Kronos Research did not immediately respond to Cointelegraph’s request for comment.
