100 Million Android Users Warned Against Using this "Very Dangerous" VPN App


Millions of Android users are being cautioned against using a popular Android VPN that was removed by Google from its Play store. The action was taken by Google after Researchers found vulnerabilities in 'SuperVPN' that could leave devices open to malware attacks and allow attackers to redirect victims onto malicious servers.

As of now, the app has around 100 million downloads, however, in the year 2016 when the risks associated with the app surfaced for the first time ever in related research, it only had a total of 10,000 downloads.

While testing, security researchers identified three main issues with the app:

1. Unencrypted HTTP traffic: The communications can be intercepted by the attackers, it has been said that transferring highly sensitive information over HTTP is not secure at all.

2. Hardcoded encryption keys: The app has inbuilt decryption keys that can easily decrypt the information in an encrypted format.

3. Payload including EAP credentials: EAP credentials are being used by the VPNs therefore users outside the app can not connect to the same server. Hence, EAP credentials sent in the unencrypted payload in a way defeats the purpose.

Notably, SuperVPN was also listed as one of the top 5 VPN in Google Play Store's search results before it was taken down by the authorities. As per the findings by researchers, it contained vulnerabilities that allowed attackers to carry out man-in-the-middle attacks, also known as MITM attacks. It could expose communication that took place between the user and provider letting hackers have access to everything the user is doing online, be it browsing tabs in Chrome, making video calls or loading up apps – all of that sensitive data including passwords, private texts, and voice messages is being made available to the attackers.

Other occasions where SuperVPN drew negative remarks include the app being ranked third by the Australian researchers in an examination of the most malware-rigged VPN apps. The researchers pointed out that the app had been posing risks since it appeared on the Play Store.

While explaining more about the issues, Jan Youngren, Security Researcher at VPNPro told, "SuperVPN used a wide range of shady techniques to help it rank highly in Google, as well as to hide who actually owns the app, where it’s located, and the other apps from the same developer that may have similar issues."

"But lastly, and most importantly, it seems that the entire time the app was on the Play store, it had critical vulnerabilities in one way or another, either by being a vehicle for malware in 2016 or allowing for MITM attacks just before being removed."

"The only thing unclear now is whether these vulnerabilities are due to mistake, or intention. Nonetheless, there are millions of users right now with a dangerous app on their phone. If you’re one of those users, we implore you to delete SuperVPN immediately." He further added.

Google removes 16 apps infected by 'Agent Smith' malware

Every now and then, Android keeps getting visited from deadly malware attacks that put user and their data at lots of risks. This time, it's a new malware called Agent Smith and like its name, this malware is sneaky in what it's designed to do - bombard your phone with ads. Agent Smith also has properties to stick to other apps installed on the phone and ensure that the malware infection stays the same. The malware was first detected by Check Point and after working with Google, the infected apps have been removed from Google Play Store.

After it was informed of the infection, Google has identified and removed 16 apps from the Play Store that are known to be infected by Agent Smith. These apps are no longer available for download from the Play Store and there won't be further updates for these apps via the Play Store. However, Google can only remove the app from the Play Store but it can't wipe these apps from an individual's Android phone. Hence, if you have the following apps installed on your Android phone, you should uninstall them immediately.

Play Store Gaming Apps Infected with Malware

An android malware named “AdultSwine” has attacked children-friendly gaming apps in the play store. Over 60 apps have been pulled by Google after recognizing the malware.

The malware causes pornographic content to show on the devices while the infected app is running, aside from trying to get users to install fake security apps and charging for unregistered premium services. The malware reportedly has the ability to steal user credentials.

The malware was discovered by researchers at Checkpoint and the affected apps have since been pulled by Google, and the developers’ accounts banned.

The affected apps have been downloaded as much as 3 to 7 million times, according to Play Store data.

A comprehensive list of affected apps and related research can be found on Checkpoint’s research blog. Google will continue to send notifications to phones that have the affected apps installed.

Android SMS malware hosted on Google Play infects 1.2 Million users


Experts often suggest to download android apps only from Google Play to avoid malware infection.  But, it doesn't mean that we can trust all of the apps hosted on Google.  

Security researchers from Panda security has found more than five malicious apps being hosted on Google play.

The apps in question appear to be targeting users in Spain.  Name of the apps are in Spanish: “Peinados Fáciles” (Easy Hairdos), “Dietas para Reducir el Abdomen” (Abs Diets), “Rutinas Ejercicios para el Gym” (Workout Routines) and “Cupcakes Recetas” (Cupcake Recipes).

The apps obtain phone number of the infected device from WhatsApp and uses it to sign the victim up to a premium rated SMS subscription services.

Researchers say that each of these apps have been downloaded by between 50k and 100k users. It means that between 300k and 1.2 Million users might have affected this malware.

“The truth is that fraudsters are making insane amounts of money from these premium services. A conservative estimate of, let’s say, €20 paid by each user would result in a huge sum of 6 to 24 million euros stolen from victims”, said Luis Corrons, Technical Director of PandaLabs.

According one of the Reddit comment, the fake apps asked permissions for 'approximate location', 'percise location', 'full network access', 'read phone calls', 'mod or delete data on your sd card', 'find accounts', 'control vibration', ladies, 'run at startup', 'test access to protected storage'.
