A new Android malware called Guerrilla has been discovered that has infected millions of devices around the world. The malware steals personal information from users, including their passwords, credit card numbers, and other sensitive data. Guerrilla can access and steal data from any app on the user’s device.
New Android malware Guerrilla Infects Millions of Devices
The expert group in security Trend Micro is the one who has detected this threat. The malware is particularly dangerous because it can infect devices even if they are running the latest security updates. This is because Guerrilla does not infect devices through apps, but rather by modifying the device’s ROM.
The ROM is the core software that runs on an Android device. It is responsible for loading the operating system and managing the device’s hardware. Modifying the ROM is a complex process that requires specialized knowledge and tools.
So, it is believed that Guerrilla was created by a group of cybercriminals who are known for developing sophisticated malware. Experts believe that the group has been active for several years and is based in China.
