Biannual threats report documents 450%+ increase in dark-web posts mentioning AI agents for fraud and 25% rise in malicious bot transactions targeting merchants.

Amazon activated automated purchase capabilities within its Rufus shopping assistant this week 1, allowing users to complete product orders through conversational interaction without leaving the Amazon interface. Perplexity launched a direct-buy feature integrated with PayPal 2, the second AI search platform to connect purchase intent to payment processing in the same week.
Visa published its PERC (Payment Ecosystem Risk and Controls) fall 2025 report 3, categorising agent-specific threats across three domains: credential hijacking in multi-agent delegation chains, manipulation of agent decision logic through adversarial prompt injection, and replay attacks using captured agent authorisation tokens.
Amazon Rufus joins Walmart’s ChatGPT checkout 4 and Stripe’s ACP Instant Checkout 5 as the third major retail platform to deploy agent-initiated purchase capability. Perplexity’s PayPal integration mirrors the Stripe-ChatGPT model: an AI interface paired with an existing payment processor, neither of which owns the other’s infrastructure.
The Visa PERC report is the first security-focused publication from a payment network addressing agent-specific threats. All three lanes active this week — Pilots, AEO, and Security — recorded first or second events in the same week; Security recorded its first event in the tracking period.
