Welcome Aanjhan :-) Happy to see you delurk. I recently read about a scam that some Ola cab drivers pulled on Ola to the tune of several lakhs per month for several months in falsified rides using GPS spoofing software and a thousand sim cards.
Impressive that this was done by your average cabbie who's not a hacker. The spoofing CD sells for ₹40k among cabbies. How easy would it be to divert a plane with this sort of spoofing? I assume one would need a fast plane, like a drone, some long range antennae and intent. Quite realistic in the modern battlefield I suppose. Do you think of yourself as a cyber weapons manufacturer? :-)
