Well, it looks like vishing is coming back (phishing using fake voicemail messages). This is when you receive an email stating you have a voicemail on a cloud collaboration provider technology. There isn’t a voicemail, but the victim will click the email and follow through the login steps to attempt to access the voice. By doing this, they give up their credentials. Other forms of this attack send the user to an exploitation page.
The lesson learned is to be careful about random voice mails. They may not be real. My advice is if you believe the voicemail could be real, DONT CLICK THE LINK. Instead, go to the service provider directly (example WhatsApp), login in and see if you have a voice mail.
