For tech-focused scammers, knocking off sneakers and handbags is so last decade.

Thieves in the digital age are slamming consumers right in the app.

A slew of knockoff shopping apps have quietly infiltrated Apple’s App Store in recent months, looking to lure unsuspecting iPhone owners with bogus deals on everything from jewelry to designer duds.

The fake apps mimic the look of legit apps — and have proliferated since this summer, experts said.

It didn’t help that earlier this month, Apple introduced search ads in its App Store. The fake apps are buying search terms, it would appear, to increase their exposure to consumers.

The crooks are looking to tap into the fast-growing market for mobile sales, which last year leaped 56 percent to $49.2 billion, according to comScore.

Late last week, a slick-looking app bearing the Coach label was dangling “an extra 20 percent off” bags, shoes and accessories.

Coach doesn’t have an iPhone app, it said.

Fake apps for other luxury brands, like Moncler, Celine and Salvatore Ferragamo, have spread, too, on the App Store, with some boasting impressive traffic.

Rapper Kanye West and his fans have likewise been victims. A fake app called “Sports Shop: Yeezy Boots” has been attracting 7,600 visitors a day, according to Apptopia, as it promises steep markdowns on West’s Yeezy Boost footwear line.

Up to now, fake versions of blockbuster apps, like Minecraft and Pokemon Go, have mainly been sold on the web and on social networks like Facebook and Instagram.

But in the App Store, simply type into the search box the name of a certain popular retail brand — say, Michael Kors, whose only legit app is for a fitness tracker — and the fake app surfaces near or even above legitimate apps.

The fake “Shopping Online for Michael Kors” app was promising discounts of 30 to 50 percent.

In the case of brands that do have shopping apps, the fake apps are made to mimic the real one — and sport voluminous merchandise pages, selector wheels for size and color, and sophisticated checkout forms that can themselves spot fake addresses and credit-card data.

Thousands of unsuspecting shoppers may download any of the fake apps and unwittingly send the thieves a wad of cash, thinking they are making a legit purchase.

“This is the first year we’re seeing this kind of proliferation with Apple, and the brands are losing the game of Whack-a-Mole,” said Chris Mason, CEO of Branding Brand, a software developer that creates websites and apps for retailers like Ralph Lauren, Sephora and Levi’s.

Apple officials didn’t comment.

Fake shopping apps discovered by Branding Brand earlier this month appeared to be boosting themselves with the new search-ad feature in Apple’s App Store, Mason notes.

A recent search for “Dollar Tree” produced not only a fake app for the discount chain, but an ad for a fake app spoofing its rival Big Lots directly above it.

While the sheer number of potential brands to impersonate makes policing harder, a single developer was recently operating as many as 35 bogus iPhone apps, many of them aping major brands like Converse, UGG Boots and Louis Vuitton.

On Friday, one shopper using a fake Dillard’s app tried to buy three pairs of leggings for $198.95. The app tried to collect the money but the purchase was rejected.

The shopper was saved from losing the cash because the gift card being used for the purchase had only $100 left on it.
