GoKawiilMalwarebytes warns AI email assistants are vulnerable to prompt injection phishing
Cybersecurity firm Malwarebytes reports that AI agents handling email can be manipulated by prompt injection attacks, where hidden instructions invisible to humans are embedded to hijack the assistant's behavior. The company says this differs from traditional phishing because the AI, not a person, is being deceived, and current fixes rely on filtering hidden content before it reaches the model.
GoKawiil's interpretation of the reporting above, not reported fact.
The report suggests that as autonomous AI agents take over more email and browsing tasks, traditional advice to 'look carefully' at suspicious messages becomes insufficient since the AI itself can be fooled even when a human wouldn't be. Developer Apollo Raines' comment that models can't distinguish content from commands points to a structural weakness that could require vendors to redesign how AI processes incoming text rather than relying on user vigilance alone.
