My first impression was that the memo is fake. The author refers to people (such as Shantanu Ghosh) without titles; and from what I recall of Indian bureaucracy, titles are important and you just don't drop them. They would always say "Hon. XYZ" or "Shri ABC". Plus, it looks like the contents of the intercepts listed were there for gratuitous purposes only. I could be wrong, though.
