US cryptocurrency firm Harmony said on Friday that hackers stole around $100 million from it.
According to the California-based company, hackers hit a tool to transfer cryptocurrencies from one system to another.
According to Elliptic, a London-based analytics firm, hackers took a number of different cryptocurrencies from Harmony, including Ether, Tether and USD Coin, which they then converted through so-called decentralized exchanges.
This theft is only the latest in a long series. In March, hackers extracted around $615 million worth of cryptocurrency from Ronin Bridge, another company. According to the American authorities, this theft would have been perpetrated by North Korean pirates.
In all, hackers have already stolen more than a billion dollars since the beginning of the year, according to Elliptic.
