# Evaluation of packer type estimation/detection tools
We evaluated two packer type estimation/detection tools ([pypeid](https://github.com/FFRI/pypeid) and [Detect It Easy (DIE)](https://github.com/horsicq/Detect-It-Easy)) to fix [this issue](https://github.com/FFRI/ffridataset-scripts/issues/1).
## Summary
DIE can detect packed binaries and estimate the type of packer with high precision compared with pypeid. However, the detection coverage of DIE is slightly lower than pypeid. See [results](#Results) for more details.
## Dataset used for evaluation
We use two datasets for evaluating packer type estimation/detection tools.
- [PackingData](https://github.com/chesvectain/PackingData)
- [RCE\_Lab](https://github.com/apuromafo/RCE_Lab)
### PackingData
This dataset contains both packed and normal (i.e., non-packed) binaries, which are used in the paper titled ["All-in-One Framework for Detection, Unpacking, and Verification for Malware Analysis."](https://www.hindawi.com/journals/scn/2019/5278137/) Since it contains both packed and normal binaries, we use it for the performance evaluation of both the packer type estimation and detection.
**Specification**
- It contains 458 normal binaries.
- It contains 2469 packed binaries.
- These binaries are created by packing 130 PE files using the following 19 packers (but 129 PE files for JDPack):
- ASPack, BeRoEXEPacker, FSG, JDpack, MEW, MPRESS, Molebox, NSPack, Neolite, PECompact, Petite, Packman, RLPack, UPX, WinUpack, Yoda’s Crypter, Yoda’s Protector, eXpressor, exe32pack
**Notes about PackingData dataset (2021/03/11)**
We noticed that PackingData dataset contains some mislabeled samples after publishing the [first evaluation result](https://github.com/FFRI/PackerDetectionToolEvaluation/tree/ae0f653ade67e5e0d9d0d7d996dd9816e09a1a3c).
(For example, `PackingData/Notpacked/avs_check_x86.exe` is [an UPX packed-binary](https://www.virustotal.com/gui/file/2fd27a3f6c9644b8105c7934d0f41fe10b056e327491df37750d634336f4b2db/details), but labeled as `NotPacked`.)
So, we changed the labels of some samples for the precise evaluation.
To fix the labeles of mislabeled samples, please run [change\_dataset\_labels.py](./change_dataset_labels.py) script.
TPRs and FPRs slightly differs from the previous result, but the [conclusion does not change](#summary).
### RCE\_Lab
This dataset contains binaries packed by various different packers. We only use the binaries in `tuts4you/Unpack*` for evaluation. Since this dataset does not contain normal binaries, we mainly use it for evaluating the performance of packer type estimation.
## Results
### PackingData
The following table shows the comparison of packer type estimation performance between pypeid and DIE. You can see the DIE's improvement of estimation performance to pypeid.
| | pypeid | DIE |
| --- | -----: | ----: |
| Accuracy | 73.2% | **84.9%** |
The following table shows the comparison of packer detection performance between pypeid and DIE. You can see the great reduction of FPR for DIE compared with pypeid.
| | pypeid | DIE |
| --- | -----: | ----: |
| TPR | 94.5% | 93.5% |
| FPR | **54.8%** | **0.7%** |
### RCE\_Lab
The following table shows the comparison of packer type estimation performance between pypeid and DIE. You can also see the improvement of estimation performance in this dataset.
| | pypeid | DIE |
| ---- | -----: | ----: |
| Accuracy | 65.1% | **69.0%** |
The following table shows the comparison of packer detection performance between pypeid and DIE. We do not show the FPR because this dataset does not contain normal binaries. The packer detection performance of DIE is slight lower than pypeid.
| | pypeid | DIE |
| --- | -----: | ----: |
| TPR | 88.2% | 83.1% |
## How to reproduce the results?
