Google has scrambled to remove third-party apps that led users to child porn sharing groups on WhatsApp in the wake of TechCrunch’s report about the problem last week. We contacted Google with the name of one these apps and evidence that it and others offered links to WhatsApp groups for sharing child exploitation imagery. Following publication of our article, Google removed that app and at least five like it from the Google Play store. Several of these apps had over 100,000 downloads, and they’re still functional on devices that already downloaded them.
