ION Cleared Derivatives, a division of ION Markets, was hit by a cyber attack earlier this week, which has impacted its ability to run overnight processing of derivatives trades on its platform. LockBit, the Russian-linked ransomware group, has claimed responsibility for the attack.

According to reports, 42 of ION’s customers have been affected by the attack, with several forced to process trades manually. The FIA (Futures Industry Association) is working with affected members to assess the impact of the attack, which is ongoing.
