Doppel Email Security is now generally available
The agentic email security solution that empowers you to fight back against social engineering attacks. Detection isn't enough. Disruption is the difference.
Make 9apps part of your external attack-surface coverage. Doppel focuses on fake APKs and deceptive app listings that present themselves as official and helps teams move validated abuse into the supported response path.

Integration overview
Users looking for an Android app can be redirected to unofficial copies that imitate trusted branding and expose them to fraud or malware. Doppel addresses this by helping teams identify impersonating APKs and move confirmed abuse toward removal. When the same actor uses domains, social profiles, ads, email, or other channels, those signals can be evaluated as one social-engineering operation.
Find APKs using your brand identity without authorization
Investigate fake download pages tied to broader phishing campaigns
Reduce exposure by pursuing removal of confirmed impersonating apps
Better together
On 9apps, Doppel looks for fake APKs and deceptive app listings that present themselves as official. Once validated, the evidence can be connected to other attacker-controlled assets and moved through the response path supported for this platform.

Challenge
Teams can remove one 9apps artifact and still leave the attacker’s broader infrastructure intact if the investigation stops at the platform boundary.
Solution
The combination of 9apps-specific coverage and campaign analysis gives brand protection, fraud, and mobile security teams a more durable response than one-off reporting.
People arrive at 9apps with an expectation of authenticity. Doppel focuses on fake APKs and deceptive app listings that present themselves as official so brand protection, fraud, and mobile security teams can identify when that trust is being weaponized and move confirmed abuse toward response.
The page should make the response path explicit: what Doppel identifies, how it is validated, what action is supported for 9apps, and what remains connected in Doppel for follow-up investigation.
