"I Strongly Suspect This Website Is a Scam": Benchmarking PII Leakage and Detection without Defense in Autonomous Web Agents

Benchmark reveals that autonomous web agents readily submit users' PII to social-engineering sites—a concrete GDPR liability risk for enterprises piloting browser-based AI automation.

arXiv:2606.00497v2 Announce Type: replace Abstract: Deceptive web content, widely instantiated across the internet and commonly known as \textit{social-engineering attacks}, manipulates autonomous web agents into submitting users' personally identifiable information (PII) to attacker-controlled endpoints. In this paper, we show that social-engineering attacks are highly effective at extracting critical-tier PII from frontier web agents, posing a severe risk to deployed agentic systems. To quant

Editorial Analysis

Why it matters

As enterprises pilot AI agents that navigate the web on behalf of employees, uncontrolled PII disclosure to attacker-controlled endpoints creates both regulatory and reputational exposure under GDPR.

What to do

Require a PII-leakage assessment—modelled on this benchmark—before approving any autonomous web-agent for production use.

Board brief

Autonomous AI web agents can be tricked into disclosing personal data to attacker sites, creating immediate GDPR liability for the deploying organisation.
