DU Antivirus Security app was created by the DU Group. As per the data collected from Play Store page the app was downloaded on 10 to 50 million users devices.
App Collects User Data Secretly And Passes It To Another App
Check Point researchers in a report published purport that they have detected wary activities in the app’s operation. When using the app for the first time, DU Antivirus Security app collects the following data.
Location information, if available
The collected data is then encrypted and sent to a remote server located at 220.127.116.11. Initially, researchers assumed that the server is controlled by a malware author. But after some ingenious investigation done via DNS records and in line subdomains they discovered that the domains hosted on the server were registered to a person name Zhan Liang Liu who is an employee at Baidu.
This collected information was then utilized by another app, “Caller ID & Call Block – DU Caller which belongs to the DU Group itself. The app is used to deliver users with details about incoming calls.
Google Seized the App
After all the information was gathered to prove the suspicious behavior of the app. Checkpoint warned Google about the app and it’s working on August 21. After knowing the secret behavior of the app Google deleted the app on August 24th, from the Play Store.
To get the app reinstated on the Play Store DU group had to remove the data collection code responsible for prying onto user’s data. After it was removed the app was restored on August 28th
As per, Check Point DU Antivirus Security v3.1.5 and earlier had the data collection code, however they have not tested the previous versions, to confirm their claim. Therefore, to stay protected all users should update to the latest version of app which is without the data collection code.

30 other apps to have the same mechanism
After detecting the suspicious behavior of DU Antivirus Security app, Check Point examined other apps too to see if they too have the malicious code. They claimed that they could find the code rooted in 30 other apps, 12 of which were available on the Google’s Play Store. Based on the data found on Play Store, approximately 24 to 89 million users might have installed the nasty apps that collects data without taking any permission from the user.
“These apps probably implemented the code as an external library, and transmitted the stolen data to the same remote server used by DU Caller,” researchers said.
Prior to this DU Caller app has been under for its offensive behavior. Earlier this year, Chinese media too revealed that the DU Caller app uses several versions of privacy policies to fool users and collect data from their devices even when user has granted permission or not.
Below is a table which shows name of the apps containing the data collection code that Check Point identified hosted on the Play Store.
Here is another list of the apps which feature the same code, but they are distrusted by third party websites.
While speaking with SC Media UK, Tony Anscombe, ESET’s industry ambassador said, “If it’s collecting data and passing to another app, it sounds non-malicious but it is a disclosure issue. There’s a hundred different antivirus products on the market, 10 companies dominate, and I am sure there are some products in there developed with great intentions but sometimes people don’t understand what disclosures they should make and what disclosures they shouldn’t make.”
“These stories affect the entire industry because if people lose trust with the security industry it’s bad for all of us. Also – being in the Google Play store, it undermines that. It also emphasizes the need for diversity of supply. If you are in a monoculture, then if that one provider misses something it can get mass infection. With a diverse security industry with lots of different players looking at lots of different things, then you get lower infection rates, and fewer issues, because people look at things from different places.”
