Malicious mobile apps could be created to scrape and share profile information, email addresses and more. Twitter and Facebook are warning of software development kits (SDKs) that could be embedded within a mobile application and used to harvest personal user information. The activity violates both companies data privacy policies, which prohibit third parties to harvest profile information for data monetization purposes. Facebook has removed the apps from its platform for violating its platform policies and issued cease-and-desist letters against One Audience and MobiBurn.
