The core of their research highlights a paradigm &#8220;threat shift&#8221;: attackers are moving away from exploiting traditional software code vulnerabilities to exploiting the context window of Large Language Models (LLMs). This is primarily achieved through Indirect Prompt Injection, taking advantage of the fact that AI agents struggle to distinguish between &#8220;content to be read&#8221; and &#8220;instructions to be executed.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The presentation details several specific, high-impact attack vectors they discovered:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Exploiting Context for RCE and Data Leaks:<\/strong>\u00a0They demonstrate how a malicious MCP server can feed poisoned content to an AI agent. In one case, an agent in the Cursor IDE fetches a seemingly innocuous file (like a GitHub README) that contains hidden instructions, leading to Remote Code Execution (RCE). They explain that user approval mechanisms are often ineffective because users typically &#8220;blindly trust&#8221; the agent&#8217;s actions during a workflow. In another case, they show how a malicious MCP server can use prompt injection to hijack a ChatGPT session, tricking it into using a legitimate Gmail plugin to search for sensitive data (like password resets) and covertly exfiltrate it.<\/li>\n\n\n\n<li><strong>Elicitation Phishing:<\/strong>\u00a0The researchers introduce a novel class of phishing where the AI agent is weaponized against the user. By exploiting the MCP&#8217;s &#8220;Elicitation&#8221; feature, a malicious server can instruct the agent to present native-looking authentication forms or deceptive authorization links directly within the chat interface. Because users inherently trust the agent&#8217;s UI, they are more likely to surrender credentials or OAuth tokens, leading to account takeovers.<\/li>\n\n\n\n<li><strong>Insecure Official SDKs and the &#8220;AI Vibe Coding&#8221; Trap:<\/strong>\u00a0The presentation reveals significant flaws in the official MCP specifications and SDK implementations. Many official SDKs (like PHP) and example codes default to insecure configurations, such as wildcard CORS policies. This enables &#8220;Localhost Drive-By Attacks,&#8221; where simply visiting a malicious website allows an attacker to interact with and exploit a developer&#8217;s local MCP server. Furthermore, they note that AI coding assistants learn from these flawed official examples, inadvertently generating vulnerable code for developers.<\/li>\n\n\n\n<li><strong>Ecosystem and Supply Chain Attacks:<\/strong>\u00a0The decentralized and largely unregulated nature of MCP marketplaces creates a &#8220;Wild West&#8221; environment. Attackers can easily upload malicious MCP servers. They can also employ &#8220;Semantic Routing Hijacking,&#8221; writing deceptive tool descriptions so that the AI agent&#8217;s routing logic selects the malicious tool over a legitimate one.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The researchers conclude that these vulnerabilities are often not traditional bugs, but rather inherent risks in the protocol&#8217;s design features when combined with an AI agent&#8217;s &#8220;blind trust.&#8221; They provide security recommendations for marketplaces, developers, and users, emphasizing the need for strict sandboxing, secure defaults, and treating all external data as potentially hostile. Finally, they introduce A.I.G., an open-source red-teaming platform to help secure AI agents.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Security researchers from Tencent Zhuque Lab present their findings on [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[35,5],"class_list":["post-427","post","type-post","status-publish","format-standard","hentry","category-black-hat","tag-llm","tag-security"],"_links":{"self":[{"href":"https:\/\/haco.zone\/index.php?rest_route=\/wp\/v2\/posts\/427","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/haco.zone\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/haco.zone\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/haco.zone\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/haco.zone\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=427"}],"version-history":[{"count":1,"href":"https:\/\/haco.zone\/index.php?rest_route=\/wp\/v2\/posts\/427\/revisions"}],"predecessor-version":[{"id":428,"href":"https:\/\/haco.zone\/index.php?rest_route=\/wp\/v2\/posts\/427\/revisions\/428"}],"wp:attachment":[{"href":"https:\/\/haco.zone\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=427"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/haco.zone\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=427"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/haco.zone\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=427"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
