Chinese Bank Hit by Ransomware Attack, Disrupting U.S. Treasury Market

A ransomware attack on China’s largest bank has disrupted the U.S. Treasury market by forcing clients of the Industrial and Commercial Bank of China to reroute trades, market participants said. The Securities Industry and Financial Markets Association told members that ICBC had been hit by ransomware software, which paralyses computer systems unless a payment is made, according to several people familiar with the discussions.
