fickling VS Stable-Diffusion-Pickle-Scanner-GUI

You're right! You should probably use Trail of Bits Fickling tool to investigate. https://github.com/trailofbits/fickling

I tested the Anything V3 pruned from Hugging Face, and indeed nothing funny in its pickle. I used the Fickling library to decompile it. I do not use Windows so my interests in .ckpt security are largely related to Pickle exploits— which could extract malicious code from a data file and then do something with it, but the data files themselves are not executed. I will edit this comment with lines referencing that data file.

I've been using Diffusion Bee on my Mac, and it's just gained the ability to import models (which it converts), but it is unpickling to do so— but barely. It unpickles, figures out what sort of data is in every data file and then computes what it wants from them on its own. I would love it to not use unpickling at all, so my intention is if I can figure it out, to write a script to decode the pickle file (with Fickling or otherwise) and then just do the weight calculation/assignment.

Something you won't gather from skim-reading the headline is that this is that the author has also created a tool, Fickling: https://github.com/trailofbits/fickling - to aid in playing around with pickle files.

From the article: [Fickling] can help you reverse engineer, test, and even create malicious pickle files.

Pickle scanner: https://github.com/diStyApps/Stable-Diffusion-Pickle-Scanner-GUI

Did you do a pickle scan on it already? You can find Distys pickle scanner here. If it's clean, then you could load it into Auto1111 and just do a checkpoint merge of that model at "0" (Meaning 100%) and save it as safetensor.

Safetensor is a new file format for models. Checkpoints create a security risk, since they are Python code encapsulated in binary form, so a malicious actor could put whatever code they wanted in one of those, and which is why it's recommended that you only use .ckpt models from reputable sources or use a checker like this https://github.com/diStyApps/Stable-Diffusion-Pickle-Scanner-GUI to make sure they are "clean."

If you are concerned about malware being embedded in .ckpt files, you can use an online tool to scan the models, or my Stable-Diffusion-Pickle-Scanner-GUI tool to scan your models before converting them.

I also recently updated my Stable Diffusion Pickle Scanner GUI, which you can find here: https://github.com/diStyApps/Stable-Diffusion-Pickle-Scanner-GUI Let me know what you think and if you have any suggestions for improvement!
