Agent Smith is threatening 25 million Android devices

Yesterday, July 10, cyber security agencies issued a warning about a malware called Agent Smith that is affecting about 25 million Android phones.

This malware can take advantage of Android OS weaknesses to launch attacks. Once installed, it will use malicious versions of ads pre-installed to replace applications like Whatsapp.

Agent Smith spreads through the third-party application store 9apps.com, owned by Alibaba Group (China), not from Google Play. Most victims of this malware are located in India with 15 million affected. In the US, 300,000 Android smartphones are infected and 137,000 in the UK.

According to security researchers, Agent Smith could not control the harmful ability because it runs in the background and does not appear on the phone interface.

Malware attacks Android smartphones

A typical attack works like this: When a user accidentally downloads and installs an application that contains a virus, it can be an image editing utility, a game, or an adult application. The app silently installs malware, then disguised as an official Google update tool. It is difficult for users to detect anomalies because no icons appear on the Android interface. Fake apps will then replace legitimate apps for hackers to spread ads. When users accidentally click on the ads, hackers will receive money.

Israeli security firm Check Point said that Agent Smith was developed by an anonymous Chinese company based in Guangzhou to help Android app developers in this country promote their products on overseas platform.
