Security Weekly Update: Cloudflare's Perplexity, GreedyBear, and HashiCorp's Involvements
In the digital world, a contentious debate is brewing over the use of robots.txt by Artificial Intelligence (AI) agents. This issue, which has sparked ethical, technical, and legal debates, revolves around the question of whether AI agents should be treated as bots subject to robots.txt constraints or as user proxies that should be allowed to access content as a user would.
On one side of the argument, AI companies like Perplexity argue that their AI agents act as user-driven assistants rather than traditional bots. They contend that robots.txt, being a voluntary, non-legal protocol, should not apply to them. AI agents, they argue, "assist" users by fetching content on their behalf, blurring the line between bot and user. Perplexity openly states that it does not pretend the old rules apply, betting that AI-assisted browsing will make the distinction harder to enforce.
On the other hand, content creators, supported by companies like Cloudflare, argue that robots.txt remains the de facto industry standard for websites to control automated access to their content. They contend that ignoring robots.txt undermines content owners’ control over their data and intellectual property, especially since websites explicitly use robots.txt to disallow scraping. Perplexity was accused of stealthily scraping sites that explicitly blocked it, including by evading restrictions using techniques like rotating IPs and altered user agents.
The core issue lies in the hybrid nature of AI agents, which are both automated fetchers and user proxies. This has led to calls for new norms, technologies, or legal frameworks to ensure content creators retain control and receive fair compensation if AI agents consume their content at scale.
Meanwhile, in the realm of cybersecurity, researchers at Cisco Talos discovered vulnerabilities in the Dell ControlVault, a Hardware Security Module (HSM) built into many Dell laptops. The vulnerabilities could potentially allow for tampering with the firmware on the HSM via physical access.
Elsewhere, US lawmakers are considering legislation that would require a kill-switch and location verification in future hardware, in response to concerns about potential backdoors in technology. Nvidia has reassured everyone that there are no back doors in their chips, addressing previous talks about backdoors.
In a separate development, Google has disclosed that they were a victim in the Salesforce hacks, which involved social engineering campaigns where attackers convinced employees to read off security codes. A Nigerian man was arrested in France and is being extradited to the US on multiple charges of fraud, identity theft, and other crimes, believed to be connected to these hacks.
Automated web crawling, a practice that has been part of the Internet since its inception, has also been in the spotlight. A more aggressive approach to blocking web crawlers involves using a Web Application Firewall (WAF). Researchers at Cisco Talos discovered a Remote Code Execution flaw in HashiCorp's Vault via plugin installation, which requires admin access and an information leak and audit log that allows writing to anywhere on the disk.
In HashiCorp's Vault, an admin cannot assign the policy "null", but can assign a policy with the same effect ("nil"). This could potentially bypass certain policy protections. Additionally, a TOTP code reuse protection issue allows an attacker to identify and reuse a valid but used code for authentication.
Perplexity has published a blog post to explain their current actions, stating that they are different from past practices. They argue that their AI agents do not behave like traditional web crawlers and that they respect the wishes of content creators who choose to block them via robots.txt.
In conclusion, the use of robots.txt by AI agents is contentious because robots.txt’s traditional bot management role conflicts with AI agents’ hybrid nature as both automated fetchers and user proxies. As the digital landscape continues to evolve, it is clear that new norms, technologies, and perhaps even legal frameworks will be needed to navigate this complex issue.
