Recently, there have been news of people receiving emails by scammers with regards to COVID-19 and they will claim that they are from World Health Organization: WHO.
These emails will normally ask you to provide sensitive information such as your username and passwords for certain sites. Or there might be a link or attachment which they would require you to click or download.
Do not provide any personal information nor click on any links or download any attachments as they might be able to steal your data or information. Worse is they might even download malware(s) on your device.
As per stated on WHO's website, make sure the sender has an email address such as ‘person@who.int’ If there is anything other than ‘who.int’ after the ‘@’ symbol, this sender is not from WHO.  For example, WHO does not send email from addresses ending in ‘@who.com’ , ‘@who.org’ or ‘@who-safety.org’.
Protect yourself and your data. Do not let scammers get their way.
