Dubbed Xhelper, the malware has already contaminated extra than 45,000 Android units in just the very last 6 months and is continuing to spread by infecting at least 2,400 equipment on an normal each individual month, in accordance to the hottest report printed nowadays by Symantec.

From Where Xhelper Android Malware Will come?

“None of the samples we analysed were being available on the Google Participate in Keep, and whilst it is achievable that the Xhelper malware is downloaded by people from unidentified resources, we believe that that might not be the only channel of distribution,” Symantec scientists write in its report.

“From our telemetry, we have viewed these applications mounted a lot more often on specific cellular phone models, which leads us to think that the attackers might be focusing on particular models.”

In a individual report released two months ago by Malwarebytes, scientists thought that the Xhelper malware is becoming unfold by “internet redirects” or “other shady sites” that prompt users to down load applications from untrusted 3rd-occasion sources.

“We imagine the pool of malware stored on the C&C server to be broad and diverse in performance, supplying the attacker several solutions, which include data theft or even full takeover of the device,” the scientists say.

The scientists imagine that the resource code of Xhelper is however a get the job done in progress, as some of its “more mature variants included empty lessons that had been not implemented at the time, but the operation is now absolutely enabled.”

The Xhelper malware has been found targeting Android smartphone end users mostly in India, the United States, and Russia.
