Mailqor

The idea for Mailqor came while investigating the September 2025 npmjs supply chain phishing attack, where critical packages like chalk were compromised to inject crypto-stealing malware. I realized that preventing such attacks could be addressed quite simply by offering users a trustworthy verification tool to check email senders and domain safety in real time. Mailqor was built to fill that gap by combining a browser extension and web app that flags verified or suspicious emails instantly. During development, the process evolved to leverage powerful AI models that analyze not just domain reputation but also behavioral signals, making Mailqor a practical defense against phishing and supply chain compromises.
