+# Cameradar Changelog
+
+This file lists all versions of the repository and precises all changes.
+
+## v2.0.0
+
+#### Major changes:
+
+* Cameradar is no longer a C++ application but a Golang library
+* It is also a Golang application replacing the former C++ one (the C++ Cameradar image can still be used with the tag `1.1.4`)
+* The new docker image is twice lighter (14MB vs 379MB before)
+* The Cameradar golang library enables users to build their own application around camera discovery and attack. Example of applications could be an automatic camera discovery daemon with scheduled scans, a security audit tool to check if CCTV cameras are protected from attacks by being isolated and having strong passwords, etc.
+
+## v1.1.4
+
+#### Minor changes:
+
+* Simplified use of Docker image
+* Renamed MySQL table name to be more explicit
+* Refactoring of the Golang functional tester done
+* The output was made more human readable
+* Added automatic code quality checks for pull requests
+* Added contribution documentation
+* Updated dictionaries to add user suggestions for Chinese cameras
+* Enhanced `result.json` file's format
+
+#### Bugfixes:
+
+* Fixed a bug in the functional testing in which if the `result.json` file was not formatted correctly, the test failed but was still considered a success.
+
+## v1.1.3
+
+#### Minor changes:
+
+* Added automatic pushes to DockerHub to the travis integration
+* Made travis configuration file better
+* Changed the package generation scripts to make them report errors
+* Removed old etix_rtsp_server binary from the test folder
+
+#### Bugfixes:
+
+* Fixed an issue that made it mandatory to launch tests at least once so that they can work the second time
+* Fixed an issue that made the golang testing tool not compile in the testing script
+* Fixed an issue that made the golang testing tool sometimes ignore some tests
+* The previous known issue has been investigated and we don't know where it came from. However after a night of testing I have been unable to reproduce it, so I will consider it closed
+
+## v1.1.2
+
+#### Minor changes:
+
+* Added travis integration
+* Added default environment value for Docker deployment
+* Updated docker image description with new easy usage
+* Updated README badges style (replaced flat with square-flat)
+* Build last package can now also generate a debug package if given the `Debug` command-line argument
+
+#### Known issues
+
+* There is still the issue with Camera Emulation Server, see the [previous version's patchnote](#v1.1.1) for more information.
+
+## v1.1.1
+
+#### Minor changes:
+
+* Removed unnecessary null pointer checks (thanks to https://github.com/elfring)
+* Updated package description
+* Removed debug message in CMake build
+* Added `/ch01.264` to the URL dictionary in the deployment (Comelit default RTSP URL)
+* Updated tests partially (still needs work to make the code cleaner)
+  * Variable names are now compliant with Golang best practices
+  * JSON variable names are back to normal
+  * Functions have been moved in more appropriate source files
+  * Structure definitions have been moved in more appropriate source files
+  * Source files have been renamed to be more relevant
+  * JUnit output now considers each camera as a test case
+  * JUnit output now contains errors which makes debugging much easier
+* Added header files where it was forgotten
+
+#### Bugfixes:
+
+* Fixed an issue where if you loose your internet connection during thumbnail generation, FFMpeg would get stuck forever and thus Cameradar would never finish
+* Fixed an issue where multithreading could cause crashes
+* Fixed an issue where the routes dictionary was mistaken for the credentials dictionary
+* Fixed issues with the golang testing tool
+  * Fixed automated camera generation
+  * Fixed docker IP address resolution
+
+#### Known issues:
+
+* There is an issue with Camera Emulation Server that makes it impossible for Cameradar to generate thumbnails, which is why right now the verification of the thumbnails presence is commented and it is assumed correct. It is probably an issue with GST-RTSP-Server but requires investigation.
+
+## v1.1.0
+
+#### Major changes:
+
+* There are more command line options
+  * Port can now be overridden in the command line
+  * Target can now be overridden in the command line
+* Bruteforce is now multithreaded and will use as many threads as there are discovered cameras
+* Thumbnail generation is now multithreaded and will use as many threads as there are discovered cameras
+* There are now default configuration values in order to make cameradar easier to use
+
+#### Minor changes:
+
+* The algorithms take external input into account (so that a 3rd party can change the DB to help Cameradar in real-time) and thus check the persistent data at each iteration
+* The default log level is now DEBUG instead of INFO
+* The attack logs are now INFO instead of DEBUG
+* The thumbnail generation logs are now INFO instead of DEBUG
+
+#### Bugs fixed
+
+* Fixed a bug in which the MySQL cache manager would consider a camera with known ids as having a valid path even if it weren't
+* Fixed a bug in which TCP RTSP streams would not generate thumbnails
+
+## v1.0.5
+
+* Fixed error in MySQL Cache Manager in which thumbnail generation on valid streams could not be done
+* Fixed potential crash in the case the machine running cameradar has no memory left to allocate space for the dynamic cache manager
+
+## v1.0.4
+
+#### Bugs fixed:
+
+* Fixed nmap package detection
+
+## v1.0.3
+
+#### Bugs fixed:
+
+* Corrected GStreamer check
+
+## v1.0.2
+
+#### Bugs fixed:
+
+* Fixed issues in MySQL Cache Manager
+
+#### Minor changes:
+
+* Added useful debug logs
+
+## v1.0.1
+
+### Ubuntu 16.04 Release
+
+#### Major changes:
+
+* The Docker deployment is now done using Ubuntu 16.04 instead of Ubuntu 15.10, so that it uses more recent packages.
+
+#### Minor changes:
+
+* Removed useless dependencies
+
+## v1.0.0
+
+### First production-ready release
+
+#### Major changes:
+
+* Added functional testing
+
+## v0.2.2
+
+After doing some testing on a weirdly configured camera network in a far away Datacenter, I discovered that some Cameras needed a few tweaks to the Cameradar attack method in order to be accessed.
+
+#### Major changes:
+
+* Cameradar can access Cameras that are configured to always send 400 Bad Requests responses
+
+#### Minor changes:
+
+* Changed iterator name from `it` to `stream` in dumb cache manager to improve code readability
+
+#### Bugfixes:
+
+* Cameradar no longer considers a timing out Camera as an accessible stream
+
+## v0.2.1
+
+This package adds fixes the Docker deployment package.
+
+#### Minor changes
+
+* Fixed the Docker deployment package
+* Updated README
+
+## v0.2.0
+
+### MySQL Cache Manager Release
+
+This package adds a new cache manager using a MySQL database, that can store the results between mutiple uses.
+
+#### Major changes
+
+* Added a MySQL Cache Manager
+
+#### Minor changes
+
+* Removed legacy code
+* Removed boost dependency
+* Improved debugging logs
+
+## v0.1.1
+
+### Docker release
+
+This package adds a way to deploy Cameradar using Docker.
+
+#### Major changes
+
+* Added a quick Docker deployment process
+* Added automatic dependencies downloading through CMake for the manual installation
+* Added CPack packaging for the Docker deployment
+
+#### Minor changes
+
+* Changed recommended cloning method to HTTPS
+* Added lots of informations to README.md
+

+## An RTSP stream access tool that comes with its library
+
+### Cameradar allows you to
+
+* **Detect open RTSP hosts** on any accessible target host
+* Detect which device model is streaming
+* Launch automated dictionary attacks to get their **stream route** (e.g.: `/live.sdp`)
+* Launch automated dictionary attacks to get the **username and password** of the cameras
+* Retrieve a complete and user-friendly report of the results

+## Docker Image for Cameradar
+
+<p align="center"><img src="images/CameradarV4.png" width="70%"/></p>
+
+Install [docker](https://docs.docker.com/engine/installation/) on your machine, and run the following command:
+
+```bash
+docker run -t ullaakut/cameradar -t <target> <other command-line options>
+```
+
+[See command-line options](#command-line-options).
+
+e.g.: `docker run -t ullaakut/cameradar -t 192.168.100.0/24` will scan the ports 554, 5554 and 8554 of hosts on the 192.168.100.0/24 subnetwork and attack the discovered RTSP streams and will output debug logs.
+
+* `YOUR_TARGET` can be a subnet (e.g.: `172.16.100.0/24`), an IP (e.g.: `172.16.100.10`), or a range of IPs (e.g.: `172.16.100.10-20`).
+* If you want to get the precise results of the nmap scan in the form of an XML file, you can add `-v /your/path:/tmp/cameradar_scan.xml` to the docker run command, before `ullaakut/cameradar`.
+* If you use the `-r` and `-c` options to specify your custom dictionaries, make sure to also use a volume to add them to the docker container. Example: `docker run -t -v /path/to/dictionaries/:/tmp/ ullaakut/cameradar -r /tmp/myroutes -c /tmp/mycredentials.json -t mytarget`
+
+## Installing the binary on your machine
+
+Only use this solution if for some reason using docker is not an option for you or if you want to locally build Cameradar on your machine.
+
+### Dependencies
+
+* `go` (> `1.10`)
+
+### Steps to install
+
+Make sure you installed the dependencies mentionned above, and that you have Go modules enabled (`GO111MODULE=on`)
+
+1. `go get github.com/ullaakut/cameradar`
+2. `cd $GOPATH/src/github.com/ullaakut/cameradar`
+3. `cd cameradar`
+4. `go install`
+
+The `cameradar` binary is now in your `$GOPATH/bin` ready to be used. See command line options [here](#command-line-options).
+
+## Configuration
+
+The **RTSP port used for most cameras is 554**, so you should probably specify 554 as one of the ports you scan. Not specifying any ports to the cameradar application will scan the 554, 5554 and 8554 ports.
+
+`docker run -t --net=host ullaakut/cameradar -p "18554,19000-19010" -t localhost` will scan the ports `18554`, and the range of ports between `19000` and `19010` on `localhost`.
+
+You **can use your own files for the credentials and routes dictionaries** used to attack the cameras, but the Cameradar repository already gives you a good base that works with most cameras, in the `/dictionaries` folder.
+
+```bash
+docker run -t -v /my/folder/with/dictionaries:/tmp/dictionaries \
+           ullaakut/cameradar \
+           -r "/tmp/dictionaries/my_routes" \
+           -c "/tmp/dictionaries/my_credentials.json" \
+           -t 172.19.124.0/24
+```
+
+This will put the contents of your folder containing dictionaries in the docker image and will use it for the dictionary attack instead of the default dictionaries provided in the cameradar repo.
+
+## Check camera access
+
+If you have [VLC Media Player](http://www.videolan.org/vlc/), you should be able to use the GUI or the command-line to connect to the RTSP stream using this format: `rtsp://username:password@address:port/route`
+
+## Command-line options
+
+* **"-t, --targets"**: Set target. Required. Target can be a file (see [instructions on how to format the file](#format-input-file)), an IP, an IP range, a subnetwork, or a combination of those. Example: `--targets="192.168.1.72,192.168.1.74"`
+* **"-p, --ports"**: (Default: `554,5554,8554`) Set custom ports.
+* **"-s, --speed"**: (Default: `4`) Set custom nmap discovery presets to improve speed or accuracy. It's recommended to lower it if you are attempting to scan an unstable and slow network, or to increase it if on a very performant and reliable network. You might also want to keep it low to keep your discovery stealthy. See [this for more info on the nmap timing templates](https://nmap.org/book/man-performance.html).
+* **"-T, --timeout"**: (Default: `2000`) Set custom timeout value in miliseconds after which an attack attempt without an answer should give up. It's recommended to increase it when attempting to scan unstable and slow networks or to decrease it on very performant and reliable networks.
+* **"-r, --custom-routes"**: (Default: `<CAMERADAR_GOPATH>/dictionaries/routes`) Set custom dictionary path for routes
+* **"-c, --custom-credentials"**: (Default: `<CAMERADAR_GOPATH>/dictionaries/credentials.json`) Set custom dictionary path for credentials
+* **"-o, --nmap-output"**: (Default: `/tmp/cameradar_scan.xml`) Set custom nmap output path
+* **"-d, --debug"**: Enable debug logs
+* **"-v, --verbose"**: Enable verbose curl logs (not recommended for most use)
+* **"-h"**: Display the usage information
+
+## Format input file
+
+The file can contain IPs, hostnames, IP ranges and subnetwork, separated by newlines. Example:
+
+```go
+0.0.0.0
+localhost
+192.17.0.0/16
+192.168.1.140-255
+192.168.2-3.0-255
+```
+
+## Environment Variables
+
+### `CAMERADAR_TARGET`
+
+This variable is mandatory and specifies the target that cameradar should scan and attempt to access RTSP streams on.
+
+Examples:
+
+* `172.16.100.0/24`
+* `192.168.1.1`
+* `localhost`
+* `192.168.1.140-255`
+* `192.168.2-3.0-255`
+
+### `CAMERADAR_PORTS`
+
+This variable is optional and allows you to specify the ports on which to run the scans.
+
+Default value: `554,5554,8554`
+
+It is recommended not to change these except if you are certain that cameras have been configured to stream RTSP over a different port. 99.9% of cameras are streaming on these ports.
+
+### `CAMERADAR_NMAP_OUTPUT_FILE`
+
+This variable is optional and allows you to specify on which file nmap will write its output.
+
+Default value: `/tmp/cameradar_scan.xml`
+
+This can be useful only if you want to read the files yourself, if you don't want it to write in your `/tmp` folder, or if you want to use only the RunNmap function in cameradar, and do its parsing manually.
+
+### `CAMERADAR_CUSTOM_ROUTES`, `CAMERADAR_CUSTOM_CREDENTIALS`
+
+These variables are optional, allowing to replace the default dictionaries with custom ones, for the dictionary attack.
+
+Default values: `<CAMERADAR_GOPATH>/dictionaries/routes` and `<CAMERADAR_GOPATH>/dictionaries/credentials.json`
+
+### `CAMERADAR_SPEED`
+
+This optional variable allows you to set custom nmap discovery presets to improve speed or accuracy. It's recommended to lower it if you are attempting to scan an unstable and slow network, or to increase it if on a very performant and reliable network. See [this for more info on the nmap timing templates](https://nmap.org/book/man-performance.html).
+
+Default value: `4`
+
+### `CAMERADAR_TIMEOUT`
+
+This optional variable allows you to set custom timeout value in miliseconds after which an attack attempt without an answer should give up. It's recommended to increase it when attempting to scan unstable and slow networks or to decrease it on very performant and reliable networks.
+
+Default value: `2000`
+
+### `CAMERADAR_LOGGING`
+
+This optional variable allows you to enable a more verbose output to have more information about what is going on.
+
+It will output nmap results, cURL requests, etc.
+
+Default: `false`
+

+
+## Frequently Asked Questions
+
+> Cameradar does not detect any camera!
+
+That means that either your cameras are not streaming in RTSP or that they are not on the target you are scanning. In most cases, CCTV cameras will be on a private subnetwork, isolated from the internet. Use the `-t` option to specify your target. If you are sure you did everything right but it still does not work, please open an issue with details on the device you are trying to access 🙏
+
+> Cameradar detects my cameras, but does not manage to access them at all!
+
+Maybe your cameras have been configured and the credentials / URL have been changed. Cameradar only guesses using default constructor values if a custom dictionary is not provided. You can use your own dictionaries in which you just have to add your credentials and RTSP routes. To do that, see how the [configuration](#configuration) works. Also, maybe your camera's credentials are not yet known, in which case if you find them it would be very nice to add them to the Cameradar dictionaries to help other people in the future.
+
+> What happened to the C++ version?
+
+You can still find it under the 1.1.4 tag on this repo, however it was less performant and stable than the current version written in Golang. It is not recommended to use it.
+
+> How to use the Cameradar library for my own project?
+
+See the example in `/cmd/cameradar`. You just need to run `go get github.com/ullaakut/cameradar` and to use the `cameradar` package in your code. You can find the documentation on [godoc](https://godoc.org/github.com/ullaakut/cameradar).
+
+> I want to scan my own localhost for some reason and it does not work! What's going on?
+
+Use the `--net=host` flag when launching the cameradar image, or use the binary by running `go run cameradar/cameradar.go` or [installing it](#installing-the-binary).
+
+> I don't see a colored output:(
+
+You forgot the `-t` flag before `ullaakut/cameradar` in your command-line. This tells docker to allocate a pseudo-tty for cameradar, which makes it able to use colors.
+
+> I don't have a camera but I'd like to try Cameradar!
+
+Simply run `docker run -p 8554:8554 -e RTSP_USERNAME=admin -e RTSP_PASSWORD=12345 -e RTSP_PORT=8554 ullaakut/rtspatt` and then run cameradar and it should guess that the username is admin and the password is 12345. You can try this with any default constructor credentials (they can be found [here](dictionaries/credentials.json)).
+
+> What authentication types does Cameradar support?
+
+Cameradar supports both basic and digest authentication.
+
+## Examples
+
+> Running cameradar on your own machine to scan for default ports
+
+`docker run --net=host -t ullaakut/cameradar -t localhost`
+
+> Running cameradar with an input file, logs enabled on port 8554
+
+`docker run -v /tmp:/tmp --net=host -t ullaakut/cameradar -t /tmp/test.txt -p 8554`
+
+> Running cameradar on a subnetwork with custom dictionaries, on ports 554, 5554 and 8554
+
+`docker run -v /tmp:/tmp --net=host -t ullaakut/cameradar -t 192.168.0.0/24 --custom-credentials="/tmp/dictionaries/credentials.json" --custom-routes="/tmp/dictionaries/routes" -p 554,5554,8554`
