The malware in question was a Trojan horse that allowed the company to make money through unsolicited ads and other malicious activities, all without the knowledge of phone users.
“The court ruled that the defendant Shenzhen Zhipu Technology Co., Ltd. committed the crime of illegally controlling the computer information system; the defendant Xu Li, Zhu Ying, Jia Zhengqiang, and Pan Qi were found guilty of illegally controlling the computer information system and were sentenced to three to three years and six months of jail term and each of them was slapped with a fine of 200,000 yuan.” Shenzhen Zhipu Technology Co., Ltd. is a subsidiary of Gionee. It was found guilty of planting the Trojan Horse on the Gionee phones. This practice of planting malware on phones to boost revenue has been reported in other Chinese smartphone brands as well. A number of them already run ads on their smartphones, a situation that users find annoying already. Planting malware is a different ball game entirely and is an abuse of user trust. Apart from the breech of trust issue, malware of this sort also are a drain on a user’s airtime, data subscription, and smartphone battery. Sometimes, the presence of such malware also impact the device’s performance. Source
