Transacted Hollowing

==========

[![Build status](https://ci.appveyor.com/api/projects/status/fpgr73aul25gc6kp?svg=true)](https://ci.appveyor.com/project/hasherezade/transacted-hollowing)

### Transacted Hollowing (classic)

Transacted Hollowing is a PE injection technique. A hybrid between [Process Hollowing](https://github.com/hasherezade/libpeconv/tree/master/run_pe) and [Process Doppelgänging](https://github.com/hasherezade/process_doppelganging).

### Ghostly Hollowing

Ghostly Hollowing is a similar technique, but using a delete-pending file instead of the transacted file. A hybrid between [Process Hollowing](https://github.com/hasherezade/libpeconv/tree/master/run_pe) and [Process Ghosting](https://github.com/hasherezade/process_ghosting).

You can switch to build the second variant with the help of the CMake option: `GHOSTING`. By default, Transacted Hollowing is built.

![CMake flag](img/ghosting_flag.png)

---

Characteristics:

-

+ Payload mapped as `MEM_IMAGE` (unnamed: not linked to any file)

+ Sections mapped with original access rights (no `RWX`)

+ Payload connected to PEB as the main module

+ Remote injection supported (but only into a newly created process)

![View](img/implant_view.png)

Supported injections:

-

If the loader was built as 32 bit:

```

32 bit payload -> 32 bit target

```

If the loader was built as 64 bit:

```

64 bit payload -> 64 bit target

32 bit payload -> 32 bit target

```

How to use the app:

-

Supply 2 commandline arguments:

```

[payload_path] [target_path]

```

Payload is the PE to be executed impersonating the Target.
