Tzohar / PassLLM
World's most accurate password guessing AI tool. A PyTorch implementation of PassLLM (USENIX 2025) that leverages PII and LoRA fine-tuning to outperform existing tools by over 45% on consumer hardware.
Why this job: says: fine tuning, lora; topics: lora
What it does
- State-of-the-Art Accuracy. Achieves +45% higher success rates than leading benchmarks (RankGuess, TarGuess) in most scenarios.
- PII Inference. With sufficient information, it successfully guesses 12.5% - 31.6% of typical users within just 100 guesses.
- Efficient Fine-Tuning. Custom training loop utilizing *LoRA* to lower VRAM usage without sacrificing model reasoning capabilities.
- Advanced Inference. Implements the paper's algorithm to maximize probability, prioritizing the most likely candidates over random sampling.
- Data-Driven. Can be trained on millions of real-world credentials to learn the deep statistical patterns of human passwords creation.
