Protect Yourself from Callback Phishing Scams: Key Tips and Examples
Callback Phishing Scams Overview
Callback phishing scams are a growing threat, leveraging social engineering tactics to deceive individuals into calling a phone number provided in a fraudulent email. These scams often impersonate well-known brands, creating a false sense of urgency to extract sensitive information. According to a report from Cisco Talos, malicious emails are often designed to look like they come from trusted companies like Microsoft, Adobe, and PayPal. They typically contain information about an account issue or an upcoming transaction, urging the recipient to call a listed number for resolution.

Once victims are on the phone, scammers pose as customer service agents and may attempt to gather personal information or direct individuals to malicious websites. A significant tactic used is attaching a PDF that loads automatically, circumventing email security features which usually scan for text and links.
Recognizing Callback Phishing Red Flags
It is crucial to be aware of the signs indicating a potential callback phishing scam. Red flags include:
- Urgent communication that incites fear or confusion.
- Emails containing attachments that automatically load.
- Requests for sensitive information over the phone.
Individuals should never click links or scan QR codes from emails or texts until verifying the sender through official channels. Email addresses can be spoofed, making it essential to independently verify any request before taking action.
