Global spear-phishing campaign targeting the COVID-19 vaccine “cold chain” is expanding, IBM says. The campaign targets 44 companies in 14 countries in Europe, North America, South America, Africa and Asia. The cold chain refers to companies involved in the delivery and storage of vaccines at low temperatures. IBM says attackers could be looking to infiltrate the supply supply chain to gain “privileged insight” into key topics surrounding the vaccine supply chain, including negotiations surrounding national procurement of vaccines.”]
