To put your mind at ease, usually when you work with people for years there is a line of communication that is established for information flow in both directions that allows for things to be said in an informal way, even hints like "look there" or "have a look at this" pointing you to a reference. Sometimes, you cannot quote your sources when discussing such sensitive matters, which could also reduce the value of the information. Your sources could also be wary because they are under contract with one of the players and a sensitive information leak could lead to termination of contract.

All I can tell you at this stage is that the TV2U URL has been created on the 23 January 2018 and DNS references pointing to portalsol.com updated on 4 February 2018. So this is very much an ongoing thing. The creator of the website is a highly regarded IT professional in Brazil under contract to one of the companies involved.
