(And Why Should You Care?)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Let me start with a story. Last year, my friend Anna nearly transferred $10,000 to a \u201cvendor\u201d who emailed her from her CEO\u2019s address. Turns out, the sender wasn\u2019t her boss\u2014it was a hacker using&nbsp;<strong>spoof email phishing<\/strong>.<\/p>\n\n\n\n<p>Email spoofing is when attackers forge the \u201cFrom\u201d field to make an email look like it\u2019s from someone you trust\u2014your bank, your boss, even&nbsp;<em>you<\/em>. It\u2019s like a digital disguise. And trust me, it\u2019s easier to pull off than you\u2019d think.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Spoofing_Fuels_Phishing_Attacks_%F0%9F%8E%A3\"><\/span><strong>How Spoofing Fuels Phishing Attacks \ud83c\udfa3<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Phishing thrives on trust.
