How Hackers Are Exploiting The COVID-19 Vaccine Rollout

Tessian Cloud Email Security intelligently prevents advanced email threats and protects against data loss, to strengthen email security and build smarter security cultures in modern enterprises.

Where there is uncertainty, there are cybercriminals. And the uncertainty surrounding the roll-out of the Covid-19 vaccine is creating the perfect environment for cybercriminals and their phishing scams.

According to new Tessian research:

  • 2,697 new website domains, related to the Covid-19 vaccine, were registered between 5 December 2020 and 10 January 2021. Many of these domains impersonate legitimate healthcare websites, tout misinformation around injection side effects, and falsely claim to offer guidance around timing and logistics of distribution to dupe people.
  • Some of the newly registered domains were confirmed as malicious. Tessian researchers found specific examples of domains that impersonate a legitimate O365 login in page and Apple ID login page. These pages have been designed to steal people’s account credentials.
  • 22% of the live domains take advantage of a technique called “typo-squatting” – a technique where one or two letters of a word are changed, in the hope that people make mistakes when typing the website into the URL bar or just simply miss the typo when landing on the page. One example of this is

Why do newly registered domains pose a threat?

The NHS recently issued a warning about scam emails that invite people to click on fake invitations to “register” for the vaccine. However, no registration is actually required for the real vaccine. The fake website, the BBC reports, also asks people for their bank details either to verify identification or to make a payment.

Often, scammers will register new domains to lure people to a page after they’ve clicked a link in a phishing email. Tessian researchers found that many of the vaccine-related websites contain online forms designed to harvest financial or healthcare information and, in some cases, steal people’s account credentials. For example, some of the confirmed-malicious websites impersonate an Office 365 or Apple ID page and prompt people to log-in and share their username and password.

People urgently want to find out things such as when they will get the vaccine, where can receive the jab, and many more want to research and understand potential side effects. As we’ve seen throughout the pandemic, cybercriminals are capitalizing on people’s desire for more information and are finding ways to trick people into clicking on links to fake websites or enter their valuable details.

Who is most at risk from the vaccine scams?

Anyone who is eligible for the vaccine, and anyone who is looking for information about the vaccine roll-out, should be wary about the websites they land on.

For example, concerns have been raised over U.S. health officials’ use of ticketing website Eventbrite to schedule vaccination appointments. Health departments have warned citizens of scams whereby fraudulent Eventbrite websites have been created, while The Tampa Bay Times reported that people had been charged money for vaccination slots that turned out to be fake.

One of the main concerns surrounding vaccine scams is how hackers will target older generations – those at the top of the list for the vaccine. A Tessian report published in 2020 – The Psychology of Human Error – found that people over 55 years old were the least likely to know what a phishing email was. Awareness is crucial; people must think twice before responding to these messages and be sceptical of emails or websites requesting payment or personal information at this time.

“Vaccines are the new “hot thing” for cybercriminals to use to trick people. Uncertainty over the vaccine roll-out and people's desire for information about how to get it has created the perfect storm for convincing phishing scams. ”
Tim Sadler CEO and co-founder of Tessian

Vaccine scams: what to look out for

Be wary of emails purporting to come from healthcare organizations asking you to click on links to ‘find out more’. Always check the sender name and address, particularly if you have received an email on your phone in order to verify the sender’s identity.

It’s also important to questions any websites that request personal data. Domains that spoof government healthcare websites, like the Centers for Disease Control and Prevention (CDC) are especially dangerous, as bad actors could potentially steal extremely sensitive information such as Social Security numbers and health information like insurance or medical history details.

At a time when phishing scams are rife, always think twice before entering your personal information online and remember, if it doesn’t look right, it probably isn’t.
