It was on the 2nd of August when the first signs of WireX botnet attack came, but it went on unnoticed at that time. It was only discovered when researchers began analyzing logs and then looked for the 26 character User-Agent string within the logs. Most likely during that stage, it was in the early stages of its development due to its minimal effects.

Why should we be troubled?

Website owners should be worried because those in control of the botnet now have the capability to take down several large websites – putting junk traffic to it and then by consuming too much bandwidth, the website’s pages and services will go down.

Majority of the affected applications were easily downloaded from Google Play Store, there were over 300 applications reportedly discovered which carries the malware launching the botnet through the apps. The botnet starts a background process on the affected Android device that would seem to launch an unseen browser and emulate series of endless legitimate browsing activities that would look like a human being has done it. The traffic mainly generated by the attack nodes is by HTTP (get) requests, however, there are some variants that was capable of issuing POST requests.

Google removed the discovered apps from the Play Store as soon as they got the report of the incidents, and currently, they are working on removing the apps from the phones of the affected Android devices.
