Crypto tech provider Haruko hit by cyberattack affecting 15 clients, some funds lost

Some of Haruko’s smaller hedge-fund clients may have lost assets after the provider of crypto technology to institutions was targeted in a cyberattack earlier this week that affected 15 customers, according to three people with knowledge of the matter.

The breach exposed clients’ read-only exchange application programming interface (API) details and trading data, according to messages reviewed by CoinDesk and people familiar with the incident. APIs allow clients’ and Haruko’s computers to communicate and exchange information.

The affected parties were all of Haruko’s non-whitelisted clients, according to messages from the company’s co-founder and chief technology officer, Adam Carlile, to a client and seen by CoinDesk. A whitelist allows communication only with approved computers or websites.

Haruko did not respond to repeated requests for comment.
