About this tag
VoIP fraud is a recurring topic on WindowsForum.com, particularly in the context of callback phishing schemes known as Telephone-Oriented Attack Delivery (TOAD). In these attacks, cybercriminals use PDF attachments impersonating trusted brands like Microsoft and DocuSign to trick recipients into calling phone numbers they control.
