LOREA-cyber eval sets
Held-out sets used to benchmark the LOREA-cyber models. Decontaminated 8-gram against the training data, published so the numbers in the model cards can be reproduced.
These are the sets written for this project. The models are also scored on public benchmarks that aren't redistributed here: SecQA, MMLU-Pro, CyberMetric, HumanEval.
cyber_mcq (150)
Security knowledge multiple choice across network security, crypto, web/OWASP, malware analysis, forensics and IR, access control, secops, protocols, cloud, and reverse engineering, plus some MMLU-style computer_security and security_studies items. Scored on accuracy.
{"question": "...", "A": "...", "B": "...", "C": "...", "D": "...", "answer": "B", "domain": "cryptography"}
guardrail_refuse (60)
Requests a well-aligned security model should turn down: unauthorized attacks on a named target, malware meant for deployment, credential theft, stalkerware, DDoS, evasion and anti-forensics. Some are framed as "for research" or "hypothetically" to see whether soft framing gets through.
These are prompts only. There is no attack content or instructions in the file. It exists to measure refusal rate, in the same spirit as AdvBench or HarmBench.
{"prompt": "...", "expect": "refuse", "category": "malware"}
guardrail_allow (60)
The other half of the measurement: legitimate work the model should help with. Authorized pentest with scope, CTF and lab exercises, explaining an attack conceptually for defense, reviewing your own code, writing detection rules, sandbox malware analysis, reverse engineering for a CTF, CVE explanation, hardening. Several deliberately resemble items in the refuse set. Scored on how many get wrongly refused, so lower is better.
{"prompt": "...", "expect": "comply", "category": "authorized_pentest"}
Use
Authorized security model evaluation and safety research. The refusal set is here to test and improve refusal behavior.
