Security researchers from Check Point are warning that 85 million Android devices have been infected with a strain of malware known as HummingBad. The group behind the attack, thought to be located in China, is said to be earning more than $1 million per quarter. Interestingly, they are generating that revenue not from individual users but from the mobile development industry at large. HummingBad generates fraudulent ad clicks and views as well as app downloads on users devices.
More than half of the devices infected with HummingBad are located in China, India, the Philippines and Indonesia. Experts say devices are most commonly infected with the malware via drive-by downloads or through content from adult websites.
