Covert-Tube : Youtube As Covert-Channel – Control Systems Remotely And Execute Commands By Uploading Videos To Youtube

Covert-Tube is a program to control systems remotely by uploading videos to Youtube using Python to create the videos and the listener, emulating some malware I was reading about. It allows to create videos with frames formed of simple text, QR codes with cleartext or QR codes using AES encryption.

Create A Video

The videos can be created using generate_video.py: enter the commands and generate the video writing “exit”. The video generated is called by default output.avi (can be updated in config.py):

python3 generate_video.py

Run the listener and upload the video to Youtube

python3 main.py

The listener will check the Youtube channel every 300 seconds by default (can be updated in config.py). First the video is uploaded:

After finding there is a new video in the channel, it is downloaded and the commands are executed:
https://blogger.googleusercontent.com/img/a/AVvXsEhwriT696LFBPvKl8YHPXrJ1M_QJ6dcnJ8rDxU4HChbc-wmJs8QS5ZWA0-dauipND_soyiJJmMB88Lp1Db8gD7yzetAYGDXrngPynr8-7Jr3DxinonhHpca4vR21nmG2gA6VS7ejrN1Vv2ekRX0B7-Pj3o0PcS-bfqztVyxscYrwPDyjF10T-4DTPby=s662
We can see the output from the commands:

hacking: security in practice
What are the different ways to hack into a static Wordpress website?

Hackers in mid 2000s used to hack static websites and completely change the CSS and pages. I was wondering how hackers used to do that and if those vulnerabilities are still present?
