Title: Cybercriminals Threaten to Hack EU Hospitals in Latest COVID-19 Vaccine Scam

Date Published: October 7, 2021


Excerpt: “This is very likely a scheme to steal people’s information and money. Scammers are always willing to prey on the vaccination-hesitant and those who desire a record of vaccination without actually getting the vaccine,” DarkOwl CEO Mark Turnage told ZDNet. “The offer has been circulated across multiple darknet forums and discussion groups. The cyber criminals also host a dedicated hidden service promoting their services. This very well could be a scam and they do not have the skills or access to actually hack any EU hospitals’ vaccination databases. Nevertheless, the idea is novel and it not out of the realm of possibility that hospitals are vulnerable to such record alterations”.”
