Hackers have stolen hundreds of millions of dollars from cryptocurrency holders and disrupted major retailers by targeting outsourced call centers used by American corporations to reduce costs, WSJ reported Thursday.

Coinbase faces potential losses of $400 million after hackers compromised data belonging to 97,000 customers by bribing call center workers in India with payments of $2,500. The criminals also used malicious tools that exploited vulnerabilities in Chrome browser extensions to collect customer data in bulk.

Retail attacks targeted Marks & Spencer and Harrods with hackers impersonating corporate executives to pressure tech support workers into providing network access.
