HuggingFace Transformers
PyPItransformersHuggingFace Transformers is the de facto standard library for loading, fine-tuning, and running pretrained language models from the Hugging Face Hub. It supports thousands of models across PyTorch, TensorFlow, and JAX. Production ML pipelines that serve models locally rather than via API depend on this package.

}Why this package is monitored
Model loading libraries execute code embedded in model artifacts, configuration files, and tokenizer definitions downloaded from external registries. A backdoored version of the library itself can intercept that execution path before any model is loaded.
Attestd monitors transformers using the following detection sources:
registryManually curated advisories in the Attestd registry, verified by a human analyst. Confidence 1.0.
osvOSV.dev malicious-package advisories with IDs prefixed MAL-. Confidence 0.95.
