The apps can also collect private data like the Android ID, Mac address, IMSI (which identifies the network operator the user is subscribed to), information about the OS, brand and model of the device, device specifics (like dots per inch and screen size), language, location information (from the city the device is in to the longitude and latitude), and data on installed apps like Google Play and Facebook. The leaked privacy data of user operation We can see in Figure 7 how user information and the user’s operational events can be uploaded.įigure 8. The app is able to upload user data information, installed app information, as well as attachments, user operational information, and data on activated events to a remote server. But we can still say that the app abuses privacy because the collection and transmission of personal data is unrelated to the functionality of the app.
HARVEST APP REFERRAL LICENSE
Users are actually asked to sign and agree to a EULA (end-user license agreement) which describes the information that will be gathered and used by the app. It is clear that one of the main focuses of the app is ad display and click fraud. The user is bombarded with ads with almost every action. The aggressive ads show up during many different scenarios - for example, after the app sends notices to unlock the device screen or if the user is told to connect to a charger.

If the user clicks the button to resolve the detected “Fraud SMS Broadcast Vulnerability,” then the app will just show a simple animation illustrating that the problem has been ‘resolved.’ This way, the user will think the app is working and will not be suspicious of it.įigure 5.

Or the user will be sent notifications like “10.0 GB files are being wasted,” which will prompt some kind of action.īut the data shown in these messages are fake - they are just used to add a layer of legitimacy to the app.įigure 4. For example, if the user installs another app, then it will immediately be reported as suspicious. After checking the original code, we found that most detection results from the notifications are false. Once the app is running, the user will be bombarded with “security” notifications and other messages from the malware. It is possible the malware developers knew that this tactic would not work on these devices, or they wanted to avoid being checked by Google Play during inspection periods. The excluded devices are: Google Nexus 6P, Xiaomi MI 4LTE, ZTE N958St and LGE LG-H525n. The malware code showing how specific devices are excluded from the “hide” behavior The “hide” function of the malware is explicitly designed not to run on specified devices, as seen in the code below:įigure 3.

They typically push alarmist security warnings and pop-up windows to the users.įigure 2. Since the apps are hidden, users will only see the notifications sent by the app. Technical AnalysisAfter first launching, the apps will not appear on the device launcher’s list of applications, and shortcuts will also not appear on the device screen. We notified Google of these apps, and at the time of writing all the apps have been removed from Google Play. Malicious apps found on Google Play, detected by Trend Micro Mobile Security The apps were actually able to perform these simple tasks, but they also secretly harvested user data, tracked user location, and aggressively pushed advertisements.įigure 1.

They also advertised a variety of capabilities: scanning, cleaning junk, saving battery, cooling the CPU, locking apps, as well as message security, WiFi security, and so on. These apps posed as useful security tools under the names Security Defender, Security Keeper, Smart Security, Advanced Boost, and more. In early December 2017, we found a total of 36 apps on Google Play that executed unwanted behavior.
