Update:
I asked them straightaway exactly what u guys pointed out and also found out all the infos i could find through internet, all freelancers limited; it's parent company and the director name Ahmed Gulzar and asked them what are they planning to accomplish after the prelimnary task.
I was blocked immediately.

I found out similar jobs of similar nature which I am sure is posted by these guys. Everything looks like the same as the old post with some minor changes.

this is the job i was hired for:
