Perplexity's Free AI Browser: Cybersecurity Risk Revealed
Perplexity offers free Comet AI browser; AI browsers cybersecurity time bomb
Perplexity is giving away a browser, and that tells you everything about the state of AI. Its new tool, Comet, is free as of early October. This isn't a product launch so much as a land grab in a market where every startup believes the next Chrome will be powered by a language model.
The scramble feels frantic because it is. While big companies tinker, smaller ones like Perplexity and Sweden's Strawberry are shipping. They're betting that the experience of searching and browsing can be collapsed into one AI-mediated conversation. Strawberry, still in beta, is openly hunting for users who gave up on other AI browsers like Atlas.
What they're all building, however, might be structurally insecure.
Startups are also keen to stake a claim, such as AI startup Perplexity -- best known for its AI-powered search engine, which made its AI-powered browser Comet freely available to everyone in early October -- and Sweden's Strawberry, which is still in beta and actively going after "disappointed Atlas users." In the past few weeks alone, researchers have uncovered vulnerabilities in Atlas allowing attackers to take advantage of ChatGPT's "memory" to inject malicious code, grant themselves access privileges, or deploy malware. Flaws discovered in Comet could allow attackers to hijack the browser's AI with hidden instructions.
Perplexity's free browser is a user acquisition strategy wrapped in an app. The goal is to make its AI search the default, the starting point for everything. Security appears to be a secondary concern, a problem for the next round of funding.
Recent research shows these tools can be tricked. Vulnerabilities in Atlas allowed for code injection and malware deployment. Similar flaws in Comet could let an attacker secretly redirect its AI.
The pitch is a better way to use the web. The reality may be a more dangerous one. Users flocking to these free tools are effectively volunteering as beta testers for a new class of security vulnerability.
For Perplexity, the calculation is simple. Dominate the space first, fix the problems later. The market is too new for anyone to care about safety.
This is the standard playbook for Silicon Valley, applied now to the very conduit through which we see the world. It is a massive gamble with our collective security.
