Introducing Eschecker 0.1

Email is the number one attack vector for cybercriminals. Every day, billions of messages are sent worldwide, and a large share carry hidden threats. Phishing emails impersonate banks, cloud services, or colleagues to trick recipients into handing over passwords or sensitive data. Spoofed domains make a message look like it came from a trusted business partner, when in reality it was sent from an attacker-controlled server. Fake invoices or purchase orders pressure employees into sending money or clicking on malicious links.

When a single email slips through and a user clicks, the impact can be severe. Companies face data breaches, financial theft, ransomware infections, reputational damage, and regulatory penalties. Unlike other attacks that target systems directly, email attacks rely on human error, which makes them both effective and dangerous

What Eschecker Does

• Upload an email file (.eml, .msg, or .html) for instant safety analysis.
• Verify if the sender’s domain matches the legitimate company (microsoft.com vs mic0rosoft.com).
• Detect if the mail server is flagged or blacklisted.
• Scan links and addresses inside the email for suspicious patterns.
• Check if the message delivers and behaves as expected.

Why It Matters

• Helps business owners who receive random or unexpected messages verify legitimacy before engaging.
• Gives IT teams a fast, first-level check before escalating to security tools.
• Reduces the risk of staff falling victim to spam or phishing attempts.
