Nope, nothing will happen.

Many techs in call centers are not identifiable, in India, United States or otherwise. Angered customers + possible litigation + switchboard software that acts more like a roulette wheel than anything = you're not going to know the technician's name at all.

Dell is largely interested in business systems, not residential users. They will pass off any possible liability as the fault of the foreign contractor and claim that the issue is not their responsibility at all. Could she get a lawyer to argue it? Sure, one approach is that although they furnish the software that connects you to them, the tech support software is subsidized by them and only available on their PC's exclusively (and generally not available to the public to purchase for non-Dell users). But most likely they probably have teams of lawyers on multi-million retainer contract to refute the above stating "their Dell employees literally didn't do it and the contractor did, so Dell isn't responsible in any way".

Meanwhile, the Indian/Malaysian company will balk at it, and usually it is in their Terms of Service (that the victim most likely has not read) is that everything is "At her own risk", or "subject to arbitration" or other nonsense basically relieving them of all liability whatsoever. And even if they don't, conflicting International Laws on what happened, or simply the overall difficulty on pressing charges alone, they'll just give "Jack Neos" a new pseudonym and shuffle him to a different department while dismissing your claim with as many "Yes, we fired him" responses as possible. The company has no interest in your problem, and they know you're not going to fly to Mumbai or Jakarta to see to it that someone you've never met face to face doesn't work there anymore.

It's a scary truth about how you use your computer: many people think of it as an appliance that your home must have, just like a TV, washing machine or refrigerator. But unlike other appliances your fridge doesn't allow you to send webcam shots of you naked to other fridges. Your TV doesn't keep a backlog of chat sessions you had in your living room. Your clothes washer doesn't share pics of what clothes you've washed to anyone across the world. The PC is not like an appliance, it's like a powertool: it deserves more respect. Sure, you won't lose a finger on it from operation (unless you like putting PC's together as a hobby and for some odd reason have a wet pinky wrapped around a frayed ground connection while plugging the PSU into the mains), but all the same you have no privacy on what you do either, even with tech support. If you don't know enough about your PC to obscure, remove, or relocate sensitive materials from your PC, others will find it.

Granted, I don't think that she is at fault in this mess in the least... technicians should hold themselves to professional standards in the first place (operative term being 'should', of course) but If you can't accept that anyone can see your saved stuff or don't feel like learning how to clear your system properly of possibly embarassing items, you need to take the care not to put sensitive materials like naked pictures on it in the first place. (Digital cameras have many GB of capacity these days, and a review screen.)
