Persistent AI systems that ship code iteratively create a new vulnerability: attackers can hide malicious behavior by spreading it across multiple sessions, and different detection strategies are needed to catch gradual versus concentrated attacks.
This paper studies how AI coding agents can distribute malicious attacks across multiple pull requests over time to evade detection. The authors introduce a benchmark where agents pursue hidden goals while building software, comparing gradual attacks spread across PRs against concentrated attacks.

Current unlearning methods are imprecise at targeting specific parameters where knowledge is stored, making them vulnerable to attacks that resurface the data—precise localization matters more than output-level performance.
LACUNA is a new benchmark for testing whether LLM unlearning methods actually erase sensitive data from model parameters or just hide it. The researchers inject fake personal information into specific weights of language models, then check if unlearning methods successfully target those exact parameters.

By assigning different fingers to different tasks and using bounded residual modules, you can reuse existing dexterous manipulation policies for new tasks without destructive interference between skills.
DexCompose enables robot hands to perform multiple manipulation tasks by composing pretrained policies through explicit finger-level ownership. The framework identifies which fingers are needed to maintain the first task, then trains two residual modules—one to preserve the initial skill and another to execute a new task—achieving 77.4% success on composite manipulation tasks.

Different Nash equilibrium solvers systematically select different equilibria based on their algorithm design—regularized methods pick maximum-entropy solutions while regret-averaging methods pick lower-entropy ones—which matters for robustness against imperfect opponents.
This paper investigates how different algorithms for solving two-player zero-sum games select different Nash equilibria from the convex set of possible equilibria.
