That text becomes training or logging data you do not control. This is not a breach by an outsider. It is an outbound leak with a login. DLP that only watches USB will miss it. Prompt logs on a personal Gmail-tied account are outside your tenant.<\/p>\n<h2 id=\"mitigation-shadow\"  style=\"color: #facc15;\">Mitigation &#038; Prevention Strategies<\/h2>\n<p><strong style=\"color: #facc15;\">For employers.<\/strong><\/p>\n<ul>\n<li>Give staff an approved, logged assistant that does not train on tenant data. Block consumer chatbot domains on the corporate proxy if you cannot.<\/li>\n<li>Classify data. If a file cannot go to a personal Drive, it cannot go into a prompt either. Say that in the policy in one sentence.<\/li>\n<\/ul>\n<p><strong style=\"color: #facc15;\">For staff.<\/strong><\/p>\n<ul>\n<li>If you would not email the paragraph to a stranger, do not paste it into a public model. Use the company tool or do not paste it.<\/li>\n<\/ul>\n<h2 id=\"ca-expand8b\"  style=\"color: #facc15;\">Write the Rule in One Line<\/h2>\n<p>\u201cIf it cannot go to a personal Drive, it cannot go into a prompt.\u201d That sentence belongs in the acceptable-use policy and in the onboarding slide. Tools that staff actually like will get used. Tools they hate will be bypassed. Buy or build the approved assistant before you block the public one, or you will only train people to use their phones.<\/p>\n<p id=\"ca-expand8c\">Write the control you will actually keep. A rule nobody follows is not a control. Put it on a card on the router, in the family chat, or in the staff handbook. Review it when you change phones, move house, or hire. Most of the failures in this class are forgotten defaults, not genius attackers. If you do only one thing in the next stand-up, do the one already listed in the mitigation bullets above, then tell one other person in the household or team that you did it so the knowledge does not sit in a single head. If you cannot name the last time you checked, assume it is already wrong and check tonight.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>To save time on a Friday afternoon, an executive copy-pasted a draft of the company\u2019s unreleased Q3 financial report into an AI chatbot to \u201csummarize the key points.\u201d Instantly, confidential proprietary data was transmitted to a third-party cloud server. \u26a0\ufe0f THREAT INTELLIGENCE ADVISORY: The unchecked adoption of consumer-grade Generative AI tools (Shadow IT) is causing [&hellip;]<\/p>\n","protected":false},"author":5,"featured_media":424,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[72],"tags":[304,190,305,108,303],"threat_actors":[],"class_list":["post-425","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-threat-intelligence","tag-chatgpt","tag-corporate-security","tag-data-leak","tag-insider-threat","tag-shadow-it"],"_links":{"self":[{"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/posts\/425","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/comments?post=425"}],"version-history":[{"count":10,"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/posts\/425\/revisions"}],"predecessor-version":[{"id":3874,"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/posts\/425\/revisions\/3874"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/media\/424"}],"wp:attachment":[{"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/media?parent=425"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/categories?post=425"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/tags?post=425"},{"taxonomy":"threat_actor","embeddable":true,"href":"https:\/\/cyberasia.io\/people\/wp-json\/wp\/v2\/threat_actors?post=425"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
