Overview of Mail Checker (メールチェッカー) #Security Risk リスク 分析 判定
Mail Checker (メールチェッカー) is a specialized tool designed to analyze and evaluate the security risks associated with emails. Its primary purpose is to help users identify potential phishing attempts, malicious content, and other email-related security threats. By examining email headers and body content (either in plain text or HTML), Mail Checker provides insights into the legitimacy of an email, offering a detailed assessment of the potential risks. The analysis includes checking the sender's address, the email's route, disguising techniques using similar-looking characters (e.g., 0 and O, I, l, and 1), and the authenticity of the header information. Furthermore, it verifies the legitimacy of source IP addresses and corporate site links to enhance the accuracy of its evaluation. This tool is equipped to provide a nuanced, comprehensive risk assessment, highlighting the safety of the email through a five-star rating system, where five stars represent the highest level of safety.
