• Callback Phishing

Attack Type: Callback Phishing

Callback phishing is a straightforward but dangerous scam that usually begins with a fake invoice or receipt. These attacks often appear to be a charge from a well-known company, such as Norton, McAfee, Geek Squad, or Apple. The email includes a phone number to call if the charge wasn't authorized. The goal is to get you to call that number, not to click a link.
Once you're on the phone, the attacker often poses as a customer service representative. They might ask for personal information, offer to help you “cancel the charge,” or convince you to install remote support software. From there, they can access your device, steal sensitive data, or walk you through a fake refund process that results in real financial loss.
Because there’s often no link or attachment in the email, these messages can bypass traditional security filters. Once the conversation moves to a phone call, it’s out of sight from most security tools. That’s what makes this type of attack so effective and why it’s important to verify unexpected emails or charges through official channels, not the contact info provided in the message.
