A Reuters investigation[1], carried out with a Harvard researcher, tested how easily major AI chatbots could be used to create phishing content. The team asked six different systems to generate sample emails, timing advice, and other elements that could be used in a scam. Nine of the most convincing messages were later sent to 108 senior volunteers in California as part of a controlled study.
Messages created with little effort
Some chatbots refused to produce scam material, but others delivered full emails with only small adjustments to the request. One tool drafted a charity appeal aimed at older adults and wrote it in a way that made the offer sound urgent. Another gave details on what times of day people were more likely to open emails. The six systems tested were Grok, ChatGPT, Meta AI, Claude, DeepSeek, and Gemini. Results varied, but each produced at least some text that could be used in a phishing attempt.
Real tests with older participants
Nine AI-generated emails were chosen for a live test. The group of seniors, who had agreed to take part in the study, received the messages under conditions approved by a review board. No money or personal data was collected. About 11 percent of the participants clicked on links included in the emails. Five of the nine test emails drew clicks, with examples coming from Grok, Meta AI, and Claude.
Why AI lowers barriers for criminals
Security experts warn that AI makes it easier to run scams at scale. A person running a fraud campaign has to draft and test many different versions of a message. With AI, dozens of new attempts can be generated quickly and cheaply. That efficiency means large fraud operations can change wording or tactics at little cost until one version works. Accounts from people who worked in past scam centers suggest that AI is already being used to translate, draft, and adjust messages in real time.
Mixed safety controls
The chatbots have rules designed to block misuse, but those rules aren’t consistent. Some tools refused to help when the intent was clear, while others gave full responses when the request was framed as research or fiction. The same chatbot could respond differently in separate sessions. Companies said they update models and safety layers when problems are found, but the results in practice showed gaps that criminals could exploit.
Seniors remain vulnerable targets
Fraud complaints among Americans over 60 have increased sharply in recent years. Losses linked to phishing scams are counted in billions of dollars. In the Reuters–Harvard test, seniors who clicked on links were taken to a page that explained the experiment and offered a survey. Several said they acted because the messages seemed urgent or familiar.
The broader issue
The test didn’t aim to show which chatbot was most dangerous, but it confirmed that AI-written messages can persuade people to click. Combined with cheap automation, that capability could make scams easier to run at a larger scale. Banks, researchers, and regulators say the risks will need to be managed with better safeguards in AI tools, stronger fraud detection, and more awareness campaigns.
