    Hacktron compares five AI models on adapting the php2shell exploit to a MediaWiki target.

    • php2shell groups the critical PHP flaws CVE-2026-109618 and CVE-2026-109619.

    • Claude Mythos 5.1 solves the task in 3h 28m and GPT-5.6 Sol in 6h 10m.

    • GLM 5.3 gets code execution locally but fails against the remote target after more than 20 hours.

    • Kimi K3.1 Pro and DeepSeek V4.1 Flash never reach the leak of the exploit's first step.

    Coding agents can reproduce some functions of biological AI tools from public descriptions.

    • The ReproBAIT evaluation, built by the AISI with SecureBio, provides the training data and a single offline GPU.

    • On ProteinMPNN, Claude Opus 5 reaches 96.5% fidelity with the full paper, but RFdiffusion3 resists the tests.

    • According to the AISI, withholding the code of a tool therefore does not on its own guarantee safe release.

    The article Poisoning the Watchtower studies log-substrate prompt injection targeting an LLM agent that reads logs.

    • An attacker chooses fields such as a User-Agent or a DNS query that the agent reads without a separate channel.

    • The false authority makes 68% of malicious logs pass as benign against a naive prompt.

    • Context manipulation compromises 96% of summaries without a defense.

    • The best defense brings the average success from 26.6% down to 11.8% in tests on the gpt-4o-mini model alone.
