Common Android Application Security Risks
快速回答
Android apps face risks from over-broad permissions, insecure storage, supply-chain SDKs, exported components, and sideload distribution — whether or not the APK is overt malware.
Common Android application security risks include malware, but most product teams hurt themselves with ordinary defects and supply chain.
Product defects
Listed under common APK vulnerabilities: exported components, storage, TLS, secrets, debuggable releases.
Permission sprawl
SDKs merge permissions you cannot explain in Play's Data safety form.
Supply chain
A dependency that phones home or ships a debug key. Review the APK, not only build.gradle comments.
Distribution
Users install lookalike APKs. Your identity (package + cert) is how they can tell. Fake builds are malware analysis for the victim, and a brand problem for you.
Process
Ship through a checklist so release night does not skip cert and permission diffs.
This is the non-malware half of what analysis is.
要点
- Shipping a non-malicious app still requires a security bar.
- SDKs can add permissions and tracking you did not intend.
- Sideload increases impersonation risk for your users even if your Play build is clean.
实践指引
- 01Inventory SDKs and the merged manifest on every release.
- 02Assume users will be offered fake APKs of your brand; keep an official cert story public.
下一步怎么做
常见问题
Is this only for sideload?
No. Play apps still have component and storage bugs. Sideload adds impersonation and malware kits.
Are trackers a security risk?
They are a privacy and sometimes a supply-chain risk. They also expand the merged permission set.
Where do I start for my own app?
An [assessment](/apk-security/security-assessment) of the release APK plus source, using the [vulnerability](/apk-security/common-security-vulnerabilities) list.
