A deceptive app is software that misrepresents its purpose, value, or behavior to users. It may promise rewards, premium content, money, or other benefits while hiding its real intent, such as ad fraud, data collection, phishing, or malware delivery. The deception can be in the app name, store listing, screenshots, permissions prompts, or in-app behavior.
In cyber security, deceptive apps matter because they exploit trust. Users are more likely to install software that appears to come from a legitimate marketplace or that uses familiar branding and incentives. Attackers use this tactic to lower suspicion and increase installs, while defenders look for misleading descriptions, repeated reuploads, abnormal permission requests, and behavior that does not match the listing. Security teams also rely on review pipelines and post-publication monitoring to catch apps that look benign but are actually designed to scam or compromise users.
