(Reuters) — ION Group, the financial trading services group hit by a ransomware attack last week, began bringing clients back to its cleared derivatives platform overnight, a person familiar with the matter told Reuters on Tuesday.
Hacking group Lockbit claimed responsibility for an attack on part of ION last week, disrupting clients that include some of the world’s largest banks, brokerages and hedge funds.
Lockbit said last week that a ransom had been paid, declining to say how much it was or offer proof that the money had been handed over. ION declined to comment on Lockbit’s statement.
The Futures Industry Association said on Tuesday that the companies that have been affected have been working closely with ION to reconnect to the affected platforms.
ION, an unlisted company based in Dublin, offers data and services to clients in the financial industry who use its technology to facilitate the trading and settlement of exchange-traded derivatives. Last week̵
