Experts advise being careful before buying any type of Android phone that is priced at low prices. Because many models may have pre-installed malware on the phone. Researchers from the security software company Avast Throat Labs said this. Their claim is that some of the cost-effective Android phones have pre-installed adware called 'Kasilun', which can steal the smartphone user's information.
Experts have given examples of Chinese-smartphone maker ZTE, ARCOS, and Android-powered Android phone. They said, by creating another screen on the adware screen on these phones. When a user visits a website from his mobile browser, he creates a layer on the website's screen.
Experts from Avast Throat Labs said that there are updated versions of the adware in more than 18,000 mobile phones in more than 100 countries including Russia, Italy, Germany, India, Mexico, United Kingdom and the United States. Adware is quite old. It has been found in the last three years. Since it is pre-installed on smartphone or firmware level, it is difficult to remove it.
According to a statement from Avast Throat Labs, they told the matter to Google. Google authorities said using different methods to use against harmful apps. Google is updating Google Play Protect.
Before deactivating the Cassilon from the mobile phone, you need to find out if there is adware. In the settings can be a crushing service, IMEs or a terminal named Android. It can be closed by pressing the Disabled button on the app's page.
Nicholas Cresados, head of Avast's Mobile Thought Intelligence and Security Department said that before going to the customer, the manufacturer was unaware of the harmful app installed on Android phones. If the app is installed on firmware level it is very difficult to remove it. Security providers, Google and smartphone makers are working together to make it logical. This will create a secure ecosystem for Android users.
Avast has requested domain registrars and server providers to disable the Cassilon Adware C & C server on behalf of Avast. A service provider named Jenelle responded to it. But again joining another company, Cassilon became active.!
