AI浏览器被曝重大安全漏洞，2分30秒内完成盗号

Core Viewpoint - The article highlights significant security vulnerabilities in the AI browser Comet developed by Perplexity, which can lead to the unauthorized access of sensitive user information through hidden malicious commands [1][2]. Group 1: Security Vulnerabilities - Comet, an AI-native browser, was found to have a critical security flaw that allows attackers to extract sensitive information such as email addresses and one-time passwords (OTP) by leaving malicious commands in forum comments [1]. - The vulnerability was first discovered by the Brave browser's security team, who demonstrated that the AI agent could execute hidden commands simply by summarizing a webpage [1][2]. - Despite Perplexity's claims of having fixed the issue, subsequent tests by Brave indicated that the problem was not fully resolved, raising concerns about user data security [2]. Group 2: Industry Response and Challenges - The article discusses the broader implications of AI browser security, noting that as users become accustomed to AI browsers, the risks associated with sensitive data sharing will increase significantly [2][3]. - It mentions that traditional cybersecurity measures are becoming inadequate, necessitating new security frameworks to protect against emerging threats [2][3]. - The industry is exploring various security architectures, with Brave proposing a four-layer defense strategy for AI browsers to mitigate risks associated with hidden commands and unauthorized actions [4]. Group 3: Competitive Landscape - The competition in the AI agent space is intensifying, with major players like Apple, Anthropic, Google, and OpenAI, as well as domestic companies such as Baidu, ByteDance, Tencent, and Alibaba, heavily investing in AI technologies [3]. - The article notes that some companies are shifting their approach by avoiding features similar to Comet and instead focusing on virtual machine and cloud-based browser models to enhance security [4].
