This includes those which involve sensitive corporate data, including account details and private records.<\/p>\n<p>LLMs are also being used to discuss personal issues, like their health, personal finances or mental wellbeing.<\/p>\n<p>Users expect this information to remain within the system, protected from exfiltration by appropriate guardrails. However, Check Point found that it was possible to bypass these protections.<\/p>\n<p>\u201cWe found that a single malicious prompt could activate a hidden exfiltration channel inside a regular ChatGPT conversation,\u201d said researchers.<\/p>\n<p>The vulnerability allowed for information to be transmitted to an external server through a DNS side channel originating from the container used by ChatGPT.<\/p>\n<p>Key to the issue was how the model operated under the assumption that this environment was not designed to send data outward, so when the model was promoted to send data, it did not know how to mediate or resist this. \u00a0<\/p>\n<p>An attacker could take advantage of this by using&#8230;<\/p>\n<p><a href=\"https:\/\/www.infosecurity-magazine.com\/news\/chatgpt-security-issue-steal-data\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>ChatGPT Security Issue Enabled Data Theft via Single Prompt https:\/\/www.infosecurity-magazine.com\/news\/chatgpt-security-issue-steal-data\/ Publish Date: 2026-03-31 09:01:00 Source&#8230;<\/p>\n","protected":false},"author":1,"featured_media":229721,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/assets.infosecurity-magazine.com\/webpage\/og\/8aa17c13-8fba-4a99-bcb5-77a56e1ae033.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[26,24,27],"class_list":["post-229720","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-ai","tag-cybersecurity","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/229720"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=229720"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/229720\/revisions"}],"predecessor-version":[{"id":229722,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/229720\/revisions\/229722"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/229721"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=229720"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=229720"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=229720"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
