Context
Unlike most attack tools that one can only find in cybercriminal underground markets, Lost Door is very easy to obtain. It’s promoted on social media sites like YouTube and Facebook. Its maker, “OussamiO,” even has his own Facebook page where details on his creation can be found. He also has a dedicated blog (hxxp://lost-door[.]blogspot[.]com/) where tutorial videos and instructions on using the RAT is found. Any cybercriminal or threat actor can purchase and use the RAT to launch attacks.
