PinDuoDuo
Pinduoduo, or “TEMU stands for Team Up, Exploit Down.” Pinduoduo got knocked off the Android store for installing literal backdoors into their own app to spy on their users. After being exposed by multiple media and security companies, Pinduoduo denied all the accusations and blamed Google for taking it off the Play Store, yet quickly and silently deleted all the malicious code and disbanded the team working on it. Even CNN picked up the story.
