Hackers targeted COVID-19 vaccine supply chain

IBM says a cyberattack on companies that distribute the COVID-19 vaccine was much larger than previously thought.

Forty-four companies across 14 countries were targeted in the hack. CBSN technology reporter Dan Patterson joins CBSN's Elaine Quijano to discuss.
