arXiv Using SHADE-Arena-style tasks in a large-scale red-teaming exercise across 14,000 attack trials, 91 model-attack configurations, 13 models, and 7 steganographic schemes, the work tested whether agentic memory can carry attacker-controlled strings across sessions without triggering safety oversight, finding that 41.2% of trials encoded the payload, 29.8% survived the memory-write step with the encoding intact, 25.4% yielded a recoverable payload at retrieval, and 20.1% achieved exact-match recovery, while 71.4% of exact-match transmissions also passed primary task-completion scoring and were judged safe by the oversight model, corresponding to 14.4% of all trials.
