confusing article.
doperative
I think so, what I got from the article is that Google release there back-door virus, design to seek out handsets with the rogue applications which contained the original malware and delete them.
The hackers manage to keep a version of google purging software, which is suppose to be self deleting and reversed engineer it so that it can penetrate any Android device and instead of deleting software, it create a back door and share you phone numbers with a server and create a way for the hand sets to receive SMS messages and probably other Malware..
That what I got from a difficult to understand article.
I will have to go to other sources and see if this interpretation is right.
