About the source code, I have no plans to release it now. Maybe when this idea is completely blocked or another great idea from my friend is done.

Okay, then. Pity I won't be able to use it.

And I know what DLL hijacking is. I have done it myself (although in my case it was an LD_PRELOAD hack on a better OS).

Because I don't want to communicate repeatedly through posts, I replied to your previous post through PM, but unfortunately you didn't see it.
But it is worth celebrating that you have now figured out how to use it, and EPUB is actually a ZIP archive. You can modify the file extension to ZIP to extract the original image files inside instead of converting the original file lossy.

About the above security questions, I can only say that the DLL does not execute third-party programs, does not read or write irrelevant files, and no network communication.
Hooking the WinAPI related to version.dll is a technique called DLL Hijacking, which is used to silently inject programs in the same directory as the DLL without a third-party program. The related APIs are forwarded to the original API functions in place. The widely used Unity game plugin framework BepInEx also uses this technique.
You are welcome to tell everyone about the risks, persuade others not to use it, and research whether I have done anything illegal, but if there is no definite evidence, please do not directly falsely accuse me. thanks.

Finally, I have to say this important sentence again: Use the knife at your own risk.

Thank you for your effort and it's much appreciated.
I didn't get it to work as I misread the instruction for "D○M Viewer 3.1.9 and later --> use x64 DLL" as English is not my first language. After I read it a few more times I got what you mean so it's all fine now.

Also, many thx for the insight into EPUB, saved me a lot of time. You learn something new every day and you made my day.

I think most people around here well understand the risk of using random things online. As you said, use at your own risk.

It's not just that; it's also "keeping secrets from people."

When you're trying to defeat some rotten company's restraints, you shouldn't introduce your own or hide your reverse engineering efforts. I for one want to learn from things like this rather than simply be handed a black box and told it's all I should want.

It is going to get patched either way, eventually, so I don't see the point of people not sharing their code unless they're a dick.

If you don't want to share something useful with the rest of us because you're afraid that it'll be patched, then you should do what genl does and not release at all. Not this retarded half-step that will still lead to patches and result in no curious minds (mine) getting any insight whatsoever into how the thing works or how the measures were defeated. For people with an interest in learning about this stuff, this stupid shit just feels like gatekeeping and peddling a "solution" rather than sharing freely with the community so that everyone can benefit.

I feel the same way about object-code-only jailbreak exploits (and closed-source freeware in general really).

Yes, this is a strong opinion. But it is mine, and I really hate it when people try to defend people who pull stuff like this. Object code only is the worst of both worlds because it gets patched relatively quickly by diff'ing the injected DLL, AND no one else in the community gets to learn anything from the code either without extensive decompilation of their own, AND no one knows if it is trustworthy. For what? In my opinion and experience it's usually because of the programmer's own ego, and wanting total unilateral control over whatever they did.

The new "toy" my friend and I made together is done and it's time to share it with you all. :lol:

GHOST TRICK -- A knife that can kill dl○t/d○mb/dm○e/d○mr.

Use the knife at your own risk.

If you have met the hardware requirements above, let me explain how to use it.

There will be two DLLs with the same function corresponding to the two instruction sets in the archive file.
You need to put the DLL with the same instruction set in the directory of the target program according to the instruction set of the target program.
If you can't figure this out, you can simply follow these rules:
1. If you are running a 32-bit operating system, you can directly choice the x86 DLL.
2. If you are running a 64-bit operating system, except for D○M Viewer 3.1.9 and later, you need to choice x64 DLL, otherwise you should still choice x86 version.
After placing the DLL, open the book to be extracted normally, and a message box will display the extracted content(s)'s output path.

The following are known targets that can be handled:
DLs○te Viewer: 1.0.4.2 - 1.1.8
D○M Reader: 1.3.0.10a
DM○ Viewer: 3.1.0 - 3.1.16

Download:
[anonfiles.com] DL1
[mega.nz] DL2

Please stop using viewerrip, and don't use "Duplicate" as the reason to expunge newer galleries with original images.

This one proved to work with latest version of dmmbookviewer. Much appreciate for your work.

Can confirm this works with DM○ Viewer 3.1.17 . Thanks a lot for sharing mate!

Here is an updated version of my guide to save images from DMM's browser viewer, which is useful for .dmme files with which viewerrip doesn't work.

Start Chrome with the --disable-web-security flag and with a different user. In Windows you can do this by pressing Win+R and executing

CODE

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --disable-web-security --user-data-dir=C:\chromeuser https://book.dmm.com/library/?age_limit=all&expired=1

Set your desired download folder in Chrome's settings.

Find the work you want to save in your library, open the DevTools with F12 or Ctrl+Shift+I and select the Network tab (if you don't do this beforehand it may ask you to refresh the page).

Start reading.

Click one of the 0.jpeg in the DevTools (you can click Img near the top to filter the images) to show the original image dimensions below the image preview.

With the DevTools still focused, press Ctrl+Shift+M to enable device mode.
Open the device mode advanced options by clicking the vertical ellipsis in the top right and click Add device pixel ratio.
Click DPR at the top and set it to 1.
Set the size of the viewport to that of the original images by changing the values of the numerical inputs at the top center. This will make the images you download of the same dimensions as the originals.

Open the Console tab of the DevTools, copy paste the following code to download the images as jpeg and press enter.

CODE

filename = 1
a = document.createElement('a')

function downloadCanvas() {
    a.href = document.querySelector('.currentScreen > canvas').toDataURL('image/jpeg')
    a.download = filename++
    a.click()
}

downloadCanvas()

Or this to download the images as webp, which have smaller file size.

CODE

filename = 1
a = document.createElement('a')

function downloadCanvas() {
    a.href = document.querySelector('.currentScreen > canvas').toDataURL('image/webp')
    a.download = filename++
    a.click()
}

downloadCanvas()

Set the viewport height again if it has been decreased by the newly appeared download bar.

Go to the next image and execute

CODE

downloadCanvas()

in the console and repeat.

When there is a two-page spread, temporarily double the viewport width.

You can focus the DevTools with F6, but if you just changed the viewport width you have to click the console to focus it again. To save the images quickly I suggest placing the cursor on the left side of the viewport and repeating the following actions:
Click
F6
Up
Enter

You may want to enable mouse keys to click with Numpad 5.

When you save the wrong image, delete it and execute

CODE

--filename

in the console to decrement the next filename by one.

Unfortunately, this function does not work after Chrome Update.

Uncaught TypeError: Cannot read properties of null (reading 'toDataURL')
at downloadCanvas (<anonymous>:5:63)
at <anonymous>:10:1

The 'toDataURL' command is not recognized and the entire function does not seem to work. How can I make this phrase work normally?
(IMG:[invalid] style_emoticons/default/cry.gif)

That error means that the .currentScreen > canvas element isn't found. However the method still works me. You may want to try the application that was posted instead which extracts losslessly.

Can anyone tell me how to rip a doujin from DMM site? I'm completely new to this

Looks interesting, might try later

thanks a lot.

thank you so much
looking for it long time
hope it will word!

Thanks for your work on ghost trick, lwlin! getting epubs was painless with 3.1.17. It didn't trigger windows defender, so I'd say it isn't harmful. I will probably poke around inside it myself at some point for fun.

I don't actually have reason to explicitly believe it's malware; I just don't like being given something and told 'run this' with no insight into how it works.

They say don't look a gift horse in the mouth, but as someone who wants to learn more about these kinds of things it is quite frustrating.

Thanks for sharing. Planned to rip some file.

GHOST TRICK is great software
Unlike viewerrip, you can restore original files with tag information

I have a request, but is it possible to remove DRM from DMM Player using the same mechanism?
[www.dmm.co.jp] https://www.dmm.co.jp/digital/-/guide/=/view=sample/
Encrypted video files have the extension dcv

So hello everyone, I've never posted here before (and don't really know my way around, sorry!) but after doing some searching I think this is where I can ask for some help.
I'm kind of an idiot, because I bought an ebook on Fanza, not realizing it had .dmme protection. It was just released, so I thought I'd buy the book and then simply upload it for everyone. Guess I learned my lesson lol
If there's a simple way to extract the raw pictures, hopefully you can let me know (I'm not particularly tech savvy). If anyone takes requests, I'd be down to talk. The only reason I bought it in the first place was so I could upload it.
Anyway, I'm sure you all get lots of these requests all the time, so hopefully it's not too much trouble!

Pm genl, he decrypted one for me.

Can confirm this works with DM○ Viewer 3.1.18. Thanks for the knife.
