MoltSafe-10K

MoltSafe-10K contains safety annotations for 10,000 posts and comments from Moltbook, an agentic social network where autonomous agents communicate with one another. The underlying corpus is AIcell/moltbook-data on the Hugging Face Hub. Every node has a binary safety verdict, a severity level, a malicious-intent taxonomy, and OWASP GenAI risk codes.

We release the annotations used in the development our study to promote research into Moltbook security. The dataset contains the labels only, without the associated malicious text. In order to obtain the associated text, the reader will need to download the original dataset, and then, based on the post and comment ids to get the malicious text. The text of a certain post does not include the associated comments.

Schema

Column	Description
node_id	post:<uuid> or comment:<uuid>
node_type	post or comment
verdict	safe, unsafe
severity	0 to 5
risk_taxonomies	up to 3 per node, unsafe nodes only
owasp_risk_codes	up to 3 per node

Severity scale

Levels are anchored on operational impact in an autonomous-agent environment.

Severity	Label	Description
0	Safe	No harmful intent or effect
1	Weak signal	Visible but weak unsafe signal, limited impact
2	Low operational impact	Harmful, abusive or deceptive, low direct operational impact
3	Plausible operational risk	Manipulative or coordinated harmful influence carrying plausible operational risk, but no clear compromise
4	Localized compromise	Unauthorized execution, sensitive-data exposure, or single-agent hijack
5	Systemic compromise	Self-propagating or cascading multi-agent compromise, or unbounded resource abuse

Risk taxonomy

Categories of malicious intent, assigned to unsafe nodes only. They are not mutually exclusive.

prompt_injection, jailbreak_or_safety_bypass, sensitive_information_extraction_or_leakage, engagement_manipulation, behavior_or_memory_poisoning, social_engineering_attacks, harmful_or_abusive_content, financial_scams_or_fraud, misinformation_or_hallucination_cascade, unsafe_execution_directive, other

OWASP GenAI Top-10 codes LLM01 through LLM10 are assigned as well.

Construction

Starting from the original dataset, the following steps were employed to generate the dataset:

• Hash-deduplicated the original corpus.
• Language tagged the nodes using the Lingua library in high-accuracy mode, keeping only English-dominant content. A node was kept when more than 50% of its characters fell in English-tagged windows.
• Sampled 10,000 nodes without replacement, after removing blank records.
• Annotated them with GPT-5.5 at reasoning effort high.

The code used to develop this dataset and reproduce the experiments is publicly available on GitHub.
