Security firm Mimecast has warned Queenslanders about the increase in potential cyber scams involving the rollout of COVID-19 vaccines. 

The warning has followed reports that cyber criminals are sending fake vaccine booking messages to steal personal information and cash from victims.

Mimecast’s cybersecurity expert, Garrett O’Hara, said it’s important to check links before clicking them to ensure they come from official sources. 

"Events like this are a perfect storm," O'Hara said.

"Many people are still working from home, there's a lot of noise about the vaccine.

"People are more likely to click on links in emails for fear of missing a spot in the vaccine queue rather than getting their information from official government and health sources.

"It's a classic case of social engineering."
