Shopping app Temu is “dangerous malware,” spying on your texts, lawsuit claimsArs TechnicaTemu "surprised" by the lawsuit, plans to "vigorously defend" itself.

Griffin's suit cited an extensive forensic investigation into Temu by Grizzly Research—which analyzes publicly traded companies to inform investors—last September. In their report, Grizzly Research alleged that PDD Holdings is a “fraudulent company” and that “Temu is cleverly hidden spyware that poses an urgent security threat to United States national interests.”

As Griffin sees it, Temu baits users with misleading promises of discounted, quality goods, angling to get access to as much user data as possible by adding addictive features that keep users logged in, like spinning a wheel for deals. Meanwhile hundreds of complaints to the Better Business Bureau showed that Temu's goods are actually low-quality, Griffin alleged, apparently supporting his claim that Temu's end goal isn't to be the world's biggest shopping platform but to steal data.

Investigators agreed, the lawsuit said, concluding “we strongly suspect that Temu is already, or intends to, illegally sell stolen data from Western country customers to sustain a business model that is otherwise doomed for failure."
