WAPDropper – Android Malware Subscribing Victims To Premium Services By Telecom Companies online dumps shop, joker stash cc

Security analysts have found a new malware that infects mobile devices and subscribes the victims to premium subscription provided by telecom companies, and the victim remains oblivious to this.
The CAPTCHA verification that is usually required to subscribe to these services is bypassed via Machine Learning using the services of a Chinese company named “Super Eagle”.
This malware has been christened WAPDropper, and belongs to a new class of malwares that have been recently discovered.
WAPDropper consists of two modules,
The dropper module is responsible for downloading the 2nd stage malware and the premium dialer module subscribes the victims to legitimate premium services. In this case, services are provided by Thai and Malaysian telecom providers.
The flow of the attack is described in the below diagram:
WAPDropper, once installed on the victim device begins to collect the below information Device ID
WAPDropper then sends the collected information to a hardcoded C&C, which is the main C&C server, and then sends the malware a list of additional C&Cs from which a random URL is picked in future.
After it receives a response from the C&C server, WAPDropper parses the JSON configuration. The JSON configuration includes instructions concerning the additional payloads that the dropper module downloads, which includes:
As it finishes downloading each payload, WAPDropper decrypts the downloaded DEX files to .jar files and stores them locally on the infected device, while it downloads the pending payloads in the background.  
Once this is done, WAPDropper loads the decrypted .jar files and deletes them from the device right away, to avoid leaving traces behind.
WAPDropper monitors the frequency of the payloads and continually sends a report on the payload’s current status to one of its C&C servers and then the dialer module decrypts a DEX file and writes it as a “data.jar”.
WAPDropper then sends a request thread to the C&C server for the server to send an ad offer.
After it receives an ad offer, the malware constructs a 1×1 pixel dialog. This tiny dialog allows the malware to load the previously unpacked native library which is responsible for removing all “X-Requested-With” HTTP headers from all HTTP requests.
WAPDropper replaces all of the occurrences of “X-Requested-With” string with “Accept-Encoding” string, which leads to immediately disabling the protection against CSRF attacks.
After this, it injects a malicious JavaScript to the new vulnerable web-view.
This JavaScript is an interface that provides a remote website capable of the following actions:
The result of this malware is that all the victims would receive massive phone bills at the end of the month, until they subscribe from this premium service.
This type of attack was very common in the late 2000s and early 2010s but was extinct with the advent of the smartphone. It made a comeback in the latter half of the 2010s when the attackers realized that the newer smartphones and telecom operators supported the older WAP standard.
