Includes source code, opcodes, processed opcodes\r\n- ​**Preprocessing**:  \r\n  Extracted opcode sequences and decoded ​**Opcode Double-Tuples (ODTs)**​ with expert-designed filtering rules\r\n- ​**Temporal Validation**:  \r\n  Split into pre-2021 (training/validation) and 2021-2024 (testing) samples. Can be used for incremental learning.\r\n\r\n## License\r\n[![CC BY-NC 4.0](https://img.shields.io/badge/License-CC_BY--NC_4.0-lightgrey.svg)](https://creativecommons.org/licenses/by-nc/4.0/)  \r\n*Academic use only. \r\n\r\n## Key Value\r\nEnables behavior-based detection models by preserving semantic context through opcode-level feature engineering.","description_withheld":null,"homepage":"https://github.com/w-32768/PHP-Webshell-Detection-via-Opcode-Analysis/blob/main/readme.md","introduced_date":"2025-02-26","introduced_date_note":null,"introduced_by":null,"license":{"name":"CC BY-NC 4.0","url":"https://creativecommons.org/licenses/by-nc/4.0/"},"modalities":[],"tasks":[],"languages":[{"name":"English","url":"/datasets/language/english"},{"name":"Chinese","url":"/datasets/language/chinese"}],"variants":["PHP Webshell Dataset"],"data_loaders":[{"repo":"https://github.com/w-32768/PHP-Webshell-Detection-via-Opcode-Analysis","url":"https://doi.org/10.5281/zenodo.14938333","frameworks":["pytorch"]},{"repo":"https://github.com/w-32768/PHP-Webshell-Detection-via-Opcode-Analysis","url":"https://github.com/w-32768/PHP-Webshell-Detection-via-Opcode-Analysis","frameworks":["pytorch"]}],"num_papers_in_archive":1,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
