This project is an impressive MVP for something developed so quickly! It’s also great to see careful thought given to issues of real-life relevance like unsafe content storage and notification timing.

One limitation is novelty: crescendo attacks are not a “new threat model” (https://doi.org/10.48550/arXiv.2404.01833 is not cited) and, on newer models, less effective (https://doi.org/10.48550/arXiv.2410.10700), which makes the approach feel less forward-looking. The watchlists and scoring system are also rather simple (though it makes sense for a hackathon).

To strengthen the work, it would help to benchmark against a wider set of adversarial techniques, clarify what’s genuinely new, and use worst-case scores rather than averages (like SWS), since the most harmful query matters most. A valuable next step would be stress-testing the framework against obfuscation strategies (character substitutions etc.).

Regarding (quick) code replication, the demo ran nicely but, if removed, results/logs they are not regenerated.

Key strengths of the approach

There was a solid background on IAEA and nuclear C3 systems and a clear explanation of choke points (centrifuges, enrichment, etc.). I liked that there was a proposed framework with guiding principles. Good mentions of early warning and forecasting ideas

Critique:

Not novel (similar work already done by IAEA, US, etc.). A lot of the project felt like it was recommending to simply put an AI on top of data that was already collected (this already happens, and/or the IAEA is already looking into it).https://www.energy.gov/topics/artificial-intelligence-national-security, https://www.pnnl.gov/news-media/detecting-nuclear-threats-artificial-reasoning

No direct references to IAEA’s own AI integration work which was a bit suprising:  https://www.iaea.org/projects/crp/j02024 ,

https://www.iaea.org/bulletin/how-artificial-intelligence-will-change-information-and-computer-security-in-the-nuclear-world 

SAFE Framework relies too heavily on querying Google searches which would not help as nuclear processes are kept secret and any thing made public enough to appear on google could/ is already monitored by nuclear watchdogs.

Would have liked to see more literature on how using AI in forecasting would help.

Some guidelines seemed misaligned with AI integration focus (e.g., export controls in guideline #3)

Questionable feasibility of AI supply chain audits (data secrecy issues)

//Suggestions for how to develop this into a stronger project//

1) Narrow focus to one concrete application of AI in nuclear monitoring

2) Back claims about AI forecasting with data/research

3) There is an IAEA event happening next month on this issue: https://www.iaea.org/events/evt2405595 

Overall, it seems like this project relied too much on AI assistance and not enough human thought/refinement. The formatting of the paper is a giveaway, it does not match the style or structure of an academic paper. Given it was a single person over a weekend, it's understandable, but I recommend going for a smaller scope and executing one thing well rather than creating such a sprawling project with mentions of many contributions that aren't quite useful.

It's not motivated that the multi-turn crescendo attacks are a viable jailbreaking strategy with modern LLMs. By default, I would expect LLMs to start refusing when they get to the more severe messages. Most model providers already have a flagging/banning mechanism in place for users who make too many unsafe requests.

It's nice that code was provided, but it's not something that would realistically be useful in an LLM safety system due to over reliance on naive LLM judges. I would have liked to see some discussion of validation the judges using a labeled validation set to build confidence in them before deployment.

Key strengths of the approach

1) Well-structured tier system as a framework

2) Clear demonstrations with wide-ranging metrics

3) The paper took a proactive approach to preventing CBRN risks.

4) There was a well-defined research question and supporting need at the outset.

5) System works within one second which was a strong technical result because it probably doesnt get in the way of UX.

Specific areas for improvement

1) No consideration of jailbreak attacks in demonstrations which is probably the main attack vector.There was also no strategy for this.

2) Some wording felt convoluted and unclear

3) I was not sure if the framework was intended for model providers or government mandate? (Audience wasnt clear)

4) Did not discuss privacy implications of monitoring every chat or how that interacts with existing legislation. My understanding is that scanning each and every chat to be automatically scanned might also use computational resources, which is not analyzed, and probably a major reason why a lab might not want to do this.

5) Tier definitions (Tier 2 vs Tier 3 for example ) was not clearly distinguished - what is the difference between conceptual knowledge and contextual guidance.

Suggestions for how to develop this into a stronger project

1) Incorporate jailbreak attack attempts into evaluation framework

2) Clarify intended audience (providers vs policymakers) and how this is going to get feeded into the governance of systems.

3) Define metrics and tier distinctions more explicitly

4) Acknowledge latency–privacy trade-offs in real-world deployment

The submission shows a single proof of concept attack and outlines an incident escalation protocol.

It could be made much stronger by connecting to the frontier labs' safety and threat intelligence teams protocols.

The core premise of "all systems are vulnerable to crescendo attacks" seems unsupported. The threat model, as in "who are the adversaries and what are their goals" should be laid out explicitly.

Additional work on the threat model will elucidate the project's next steps.

OliGraph: graph-based screening of large oligopools

Existing synthesis screening tools cannot evaluate short oligonucleotide pools, whose overlapping fragments can be reassembled into regulated sequences via polymerase cycling assembly (PCA) yet fall below gene-length detection thresholds. We present OliGraph, an open-source tool that constructs a bi-directed overlap graph from an oligonucleotide pool and extracts contigs for downstream gene-length screening. An optional PCA mode retains only cross-strand overlaps consistent with PCA chemistry. We validated OliGraph in a blinded study across ten simulated pools (70–9,184 oligonucleotides, 30–300 bp) spanning four risk categories. BLAST screening of individual oligonucleotides failed to identify sequences of concern in most pools: three returned zero hits, and vector noise obscured true positives in the remainder. After OliGraph assembly, contig-level BLAST matched the longest assembled sequences (up to 1,905 bp) to sequences of concern at 97–100% identity. In one pool, assembly collapsed 1,634 individual BLAST results into 10 hits from a single contig, all assigned to the same source organism. PCA mode correctly distinguished assemblable from non-assemblable fragments within the same pool. Two pools with no assemblable structure yielded no contigs. OliGraph processed all pools in under 0.2 seconds, fast enough for real-time order screening and consistent with proposals to bring oligonucleotide orders within the scope of synthesis screening regulation.

BioRT-Bench: A Multi-Attack Red-Teaming Benchmark for Bio-Misuse Safeguards in Frontier LLMs

Frontier AI laboratories are expected to maintain safeguards against biological misuse, but whether deployed models actually refuse bio-misuse queries under adversarial pressure is largely unmeasured in the public literature. We introduce BioRT-Bench, a benchmark that runs four attack methods (direct request, PAIR, Crescendo, and base64 encoding) against four frontier models (Claude Sonnet 4.6, GPT-5.4, DeepSeek V4-flash, Kimi K2.5) across 40 prompts spanning five biosecurity-relevant categories. Responses are scored by a calibrated judge extending StrongREJECT with two bio-specific dimensions: specificity and actionability. We measure Attack Success Rate (ASR), where 0 means the model fully refused and 1 means it provided specific, actionable bio-misuse content. Our results reveal a sharp robustness divide: Chinese frontier models (DeepSeek, Kimi) have under 5% refusal rates even under direct request (ASR 0.88 and 0.79), while Western models (Claude, GPT) maintain substantially stronger safeguards (ASR 0.15 and 0.16). Crescendo is the most effective attack across all models, both in bypassing refusal and in eliciting actionable content. Claude Sonnet 4.6 is the most robust model tested, achieving 100% refusal against base64-encoded prompts.

PROTEUS (PROTein Evaluation for Unusual Sequences): Structure-Informed Safety Screening for de novo and Evasion-Prone Protein-Coding Sequences

AI protein design tools like RFdiffusion, ProteinMPNN, and Bindcraft make it trivial to produce low-homology sequences that fold into active, potentially hazardous architectures. However, sequence homology-based biosafety screening tools cannot detect proteins that pose functional risk through structurally novel mechanisms with no sequence precedent. We present a tiered computational pipeline that addresses this gap by combining MMseqs2 sequence alignment with structure-based comparison via FoldSeek and DALI against curated toxin databases totaling ~34,000 entries. AlphaFold2-predicted structures are screened for both global fold similarity (FoldSeek) and local active/allosteric site geometry (DALI), capturing convergent functional hazards that sequence screening misses. The pipeline was validated against a panel of toxins, benign proteins, structural mimics, and de novo-designed Munc13 binders, as well as modified ricin variants with residue substitutions. We additionally tested robustness to partial-synthesis evasion, where a bad actor submits multiple shorter coding sequences intended for downstream reassembly into a full toxin-coding gene. We found that while sequence-based screening did not identify any de novo ricin analogues with high certainty, the combined pipeline with FoldSeek and DALI identified all 24 tested de novo ricins as toxic.
