Overview
Attackers use fake reviews or ratings to manipulate user trust and encourage downloads of malicious apps. Review tampering exploits the reliance users place on app store ratings and reviews to make download decisions. Malicious developers use bots or hire individuals to flood app listings with positive reviews and high ratings, masking the app’s malicious intent. Conversely, attackers may leave negative reviews on legitimate apps to discredit competitors.
Risk factors
App Store/Play Store review tampering can arise from:
- Lack of robust review moderation by app stores.
- User over-reliance on reviews without verifying app credibility.
- Insufficient scrutiny of app permissions during installation.
Consequences
If an attacker successfully exploits App Store/Play Store review tampering, the following could happen:
- Malware infection: Users may download apps containing spyware, adware, or ransomware.
- Data theft: Malicious apps can steal sensitive data like location, contacts, or login credentials.
- Erosion of trust: Legitimate developers may lose credibility due to fake negative reviews.
- Review amplification: With the app stores’ algorithmic promotion of highly rated apps, the impact of fake reviews is amplified.
Solutions and best practices
To mitigate the risks associated with App Store/Play Store review tampering, organizations should implement the following security measures:
- Verification tools: Use app verification platforms to check for authenticity.
- User awareness: Educate users on the risks of downloading poorly verified apps.
- Developer accountability: App stores should strengthen policies to detect and remove fraudulent reviews.
- App shielding: Ensure apps have strong security measures to protect against tampering or unauthorized modifications.
