callback phishing
About this tag
Callback phishing is a social engineering tactic where attackers use legitimate-looking emails, often impersonating Microsoft or other trusted brands, to trick recipients into calling a phone number controlled by the threat actor. On WindowsForum.com, discussions highlight how cybercriminals abuse Azure Monitor to send fake billing alerts that appear genuine, use PDF attachments branded as DocuSign or Microsoft to initiate telephone-oriented attack delivery (TOAD), and even leverage real Microsoft purchase notification emails to add credibility. Once on the call, victims are manipulated into revealing sensitive information or installing malware. These campaigns exploit trust, urgency, and legitimate infrastructure to bypass traditional email security filters.
