Polymorphic phishing is a sneaky type of scam where each email is slightly altered—changing subject lines, sender names, links, and design—to avoid detection by spam filters. These constant changes make it hard for traditional systems to recognize the threat. That’s where emailSONAR helps: by analyzing hidden patterns, technical metadata, and suspicious behaviors across emails, it spots the red flags no matter how the message is disguised—giving you a clear, plain-English risk report to stay safe.
