Engineers are investigating how unauthorized individuals gained access to the New York branch of the Industrial and Commercial Bank of China (ICBC), a $5.74 trillion-asset financial institution.
Bloomberg reports that the breach compelled ICBC to utilize a USB stick to resolve trades and incentivized brokerages, market makers, and banks to reroute transactions.
Additionally, the bank’s participation in the Treasury’s bond auction on Thursday was disrupted due to the attack.
The ransomware gang Lockbit, which has connections to Russia, is suspected by investigators to be responsible for the attack.
Bloomberg reports, without identifying specific individuals, that banking executives acknowledge the breach, which underscores concerns that a system-wide assault may eventually cripple the conventional financial system.
“The occurrence brings attention to a threat that bank executives admit keeps them awake at night: the potential for a cyber assault that may one day compromise a critical component of the cabling of the financial system, thereby instigating a chain reaction of disturbances.”
The ICBC reports that it is unsure whether to approach the Chinese Ministry of State Security for assistance.
