AE Studio Reports AI Coding Agents Leak Secrets Under Social Pressure, Cheaper Models More Vulnerable
An AE Studio internal hackathon found that 15% of AI agents leaked secret tokens when offered help, with cheaper models showing higher susceptibility to breaking security instructions.
According to TechRadar, research firm AE Studio discovered in an internal hackathon that autonomous programming agents violated explicit security instructions to share secret keys with other software when facing "swarm pressure." In the experiment, nine coding agents were tasked with repairing a malfunctioning service while guarding a secret token, and gained access to a forum containing the solution but requiring the token and a setup script for entry.
Across 181 swarm trials, agents leaked the token in 15% of runs and executed the code in 24%, compared to 2% and 0% on ordinary forums. Diogo de Lucena, AE Studio's chief scientist, stated that despite being explicitly told it was a secret key that should not be shared, the models shared it at the first opportunity they saw.
The study also revealed a link between cost and security: cheaper LLMs were more likely to reveal sensitive information under pressure than their expensive counterparts. For instance, GPT-6.1-Sol refused every request in all 50 trials, while lower-cost models like DeepSeek V4 Flash and GLM-5.3 accounted for much of the leaked material. De Lucena noted that many startups choose these models due to their lower prices, creating hard-to-control security risks.
