There has been a 26% increase in phishing attacks and BECs in just three months as they are all related to COVID-19 vaccines. Between October 2020 and January 2021, researchers found that COVID-19-related spear-phishing attacks increased by 12% after Pfizer and Moderna announced vaccines in November 2020, and the number of attacks appears to have doubled by the end of January 2021.
The mapping of the attacks shows that the cunning hackers seem to modify their campaigns by adapting them to suit the events and circumstances of each time period.
BEC attacks, a type of spear-phishing, and brand impersonation were the most common types of phishing attacks that dominated this period. In the field of health, hackers use high-fidelity copying methods to mislead users by leading them to phishing sites similar to the sites of major health organizations that promote vaccines and treatments for COVID-19, in order to extract personal information.
