Why is ICBC bank trading via USB stick after ransomware attack? Let’s Find out!

The US trading arm of the Industrial and Commercial Bank of China (ICBC) was hit by a ransomware attack on November 8, 2023, which forced the bank to handle trades via messengers carrying USB thumb drives across Manhattan.

The ransomware attack disrupted ICBC’s financial services systems, rendering it unable to clear swathes of US Treasury trades after entities responsible for settling the transactions swiftly disconnected from the stricken systems. The bank had to send the required settlement details to those parties by a messenger carrying a thumb drive as the state-owned lender raced to limit the damage.

The attack is believed to have been carried out by the Russia-linked LockBit ransomware gang. The bank will engage in proper supervision and communication to minimize the risks, impact, and losses.
