Pulled out relevant details of the 5 cases

1) Chikungunya - "the platform tunneled traffic through US infrastructure to evade our regional blocks, and used a zero data retention (ZDR) service to hide content."

2) bird flu - "accessed Claude from an unsupported region via US virtual private server infrastructure, using a privacy-email provider with an auto-generated username. The researcher pursued this work in a credible institutional context, and interacted with Claude over the course of several weeks, exchanging thousands of messages. In these exchanges, the researcher leveraged Claude’s knowledge of the scientific literature to assist the researcher in study planning and design, data analysis, and the interpretation and prioritization of experiments."

3) orthopoxvirus - "randomly generated email address shortly before use and operated through anonymizing US infrastructure, with operator logins traced to proxies shared with a banned account farm. It was not a single user: it was a reseller relay serving more than a dozen unrelated customers, which exchanged over tens of thousands messages with Claude in a matter of days. The grant itself was one customer’s run entirely on Opus 5 in about an hour, in which the user used Claude to draft the application end to end including the central hypothesis, experimental design, dosing, statistical plans, and contingency strategies."

4) atlas of venom toxin peptides - "the atlas contained scaffolds for both analgesic and paralytic targets: it could, therefore, be used to generate both novel therapeutic or harmful compounds. The latter are derived from toxins that are export-controlled under the Australia Group common control list due to their dual-use potential as incapacitating agents. The researchers themselves showed awareness of the dual-use nature of their work, citing journal articles that referred to the dual-use nature of protein design. Moreover, international compliance assessments for this location raise concerns about the specific class of toxins that the researcher pursued and specifically the use of AI/ML for bioweapons applications in the context of this class of toxins. In this case, we learned from information shared with Claude that the researcher’s outputs also were part of a state-supported research program."

5) computational redesign of toxins - "described state priority research under a national public research program. As a part of this research assignment, the work covered a bacterial toxin subunit and a protein of the hemorrhagic-fever virus that is on the World Health Organization R&D Blueprint priority list of diseases with the greatest epidemic and pandemic threat. "The researcher co-wrote quarterly progress reports with Claude. Notably, the identity of the bacterial toxin and viral proteins were intentionally obscured, and the researcher specifically directed Claude to keep these descriptions deliberately low fidelity."
