They can be useful in controlled business environments.<\/p>\n<p>However, attackers quickly realised that macros can also execute scripts, download payloads, and run malicious commands.<\/p>\n<p>Common macro-based attacks involve:<\/p>\n<ul>\n<li>Phishing emails with malicious attachments.<\/li>\n<li>Fake invoices or payment documents.<\/li>\n<li>Resumes sent to HR teams.<\/li>\n<li>\u201cUrgent\u201d financial documents.<\/li>\n<li>Internal-looking files spoofed to appear legitimate.<\/li>\n<\/ul>\n<p>Because Office files are widely trusted, users are more likely to open them without hesitation. If macros are unrestricted, that trust becomes an entry point.<\/p>\n<h3><strong>What Does \u201cRestrict Microsoft Office Macros\u201d Actually Mean?<\/strong><\/h3>\n<p>Restricting macros does not mean disabling all Office functionality. It means applying controlled rules to prevent untrusted macros from executing.<\/p>\n<p>In practical terms, this includes:<\/p>\n<ul>\n<li>Blocking macros from the internet.<\/li>\n<li>Allowing only digitally signed macros.<\/li>\n<li>Restricting macro execution to trusted locations.<\/li>\n<li>Disabling macros for standard users where possible.<\/li>\n<li>Monitoring macro-related activity.<\/li>\n<\/ul>\n<p>The goal is simple: prevent malicious code from running without authorisation.<\/p>\n<h3><strong>Why Macro Attacks Are So Effective<\/strong><\/h3>\n<p>Macro-based attacks work because they rely on human behaviour.<\/p>\n<p>They typically:<\/p>\n<ul>\n<li>Use urgency (\u201cPayment overdue\u201d).<\/li>\n<li>Create curiosity (\u201cConfidential salary update\u201d).<\/li>\n<li>Exploit routine processes (\u201cUpdated invoice\u201d).<\/li>\n<li>Appear legitimate.<\/li>\n<\/ul>\n<p>Even well-trained employees can be caught off guard.
