McAfee recently announced it detected 16 million mobile malware infections in the third quarter of 2017 alone. That is twice as many infections as it found in the third quarter of 2016.
One malware campaign, called Garbos, contained in 144 apps on the Google Play Store, infected around 17.5 million devices before Google removed the infected apps.
According to McAfee's Mobile Threat Report for Q1 2018, cybercriminals can now earn one to two million dollars per ad click fraud, pay-per-download, or prevalent banking trojan scam. In 2010, the highest paid malware campaigns brought in approximately $100,000 to $300,000. In 2018, pay-per-download scams alone will earn cybercriminals around $40 billion.
If this trend continues, a malware strain could bring in a billion dollars for its creators by 2020. Since cybercrime pays so well, cybersecurity experts predict that we will continue to see growing numbers of malware infections.
