NOTE: The unserialize is triggered for the phar:// wrapper in any file operation, `file_exists` and many more.

### Wrapper iconv:// and dechunk://

### Wrapper convert.iconv:// and dechunk://

|

The goal is to leak the content of a file, one character at a time.
|
||||
- `convert.iconv://`: convert input into another folder (`convert.iconv.utf-16le.utf-8`)
|
||||
- `dechunk://`: if the string contains no newlines, it will wipe the entire string if and only if
|
||||
the string starts with A-Fa-f0-9
|
||||
|
||||
The goal of this exploitation is to leak the content of a file, one character at a time, based on the [DownUnderCTF](https://github.com/DownUnderCTF/Challenges_2022_Public/blob/main/web/minimal-php/solve/solution.py) writeup.
|
||||
|
||||
**Requirements**:
|
||||
- Backend must not use `file_exists` or `is_file`.

The `Microsoft-Windows-Threat-Intelligence` provider corresponds to ETWTI, an additional security feature that an EDR can subscribe to and identify malicious uses of APIs (e.g. process injection).
|
||||
|
||||
The most common bypassing technique is patching the function `EtwEventWrite` which is called to write/log ETW events.
