As the Coronavirus pandemic continues to ravage much of the world, recently there has been cause for some hope due to reports that companies such as Moderna and others working on vaccines to fight the Coronavirus are making significant progress toward having such a vaccine fully developed and approved for use. Presently no such vaccine is approved and available however, so you should be extremely skeptical about any emails you receive with "inside" information about Coronavirus vaccines and their availability. Many people are reporting receiving emails with eye-catching subject lines such as "Urgent Information Letter: Covid-19 New Approved Vaccines" that promise to provide you with information about Coronavirus vaccines including how to get early access to the vaccines. You are them prompted to download an attachment that purports to contain all of this tremendously valuable information. Of course, if you do download the attachment, you won't get any information about a vaccine. Instead what will happen is that when you download the attachment, you download keystroke logging malware on to your computer that will steal personal information from your computer and use it to make you a victim of identity theft.
Even if you have the most up to date security software on your computer, you will not be protected from the latest zero day defects which are malware that exploit vulnerabilities that have not yet been discovered. It takes the security software companies at least thirty days after the discovery of new strains of malware to come up with defenses. Never click on a link or download an attachment unless you have absolutely confirmed that it is legitimate. In the case of unsolicited emails informing you of Coronavirus vaccines and how you can get early access to them, it will always be a scam.
