Learning Feedback
Use explanations to understand why a message appears real, suspicious, or malicious.
Why It Exists
Email spoofing is becoming harder to judge from the sender name alone.
EmailKnight gives learners a structured way to slow down, inspect evidence, and practice defensive email analysis.
As AI-assisted email spoofs become more sophisticated, users need more than a quick glance at the sender name. EmailKnight helps analyze suspicious email headers beyond standard checks such as SPF, DKIM, and DMARC, including sender identity, message structure, mail server clues, and header-level spoofing patterns.
It is designed to help users decide whether a message is likely real, suspicious, or spam while learning the logic behind the decision.
EmailKnight can be used as a local analysis workflow for pasted or saved header data, reducing dependence on browser-extension overlays or cloud-upload tools.
That does not make any tool impossible to bypass, but it helps keep analysis under the learner's control and makes page-level tricks less relevant to the review process.
Developed through research by Professor Gurmeet Singh
Professor Singh, a computer science educator, developed EmailKnight during research on AI-assisted email impersonation. In those simulations, nearly 100% of participating computer science students were deceived by convincing spoofed messages, including technically savvy students with prior coursework in cybersecurity and programming. The results also showed that even educators with substantial industry experience can be vulnerable to well-crafted impersonation attempts.
