sample functional Windows malware. Now, another "trick» Windows Trojan
malware is implemented under Android: we found the first Android-Trojan,
who as a C & C uses the domain of pseudo-zone. Onion. Thus, the Trojan
uses the anonymous network Tor, built on a network of proxy servers. In
addition to providing user anonymity, Tor allows you to post in the
blast zone. Onion «anonymous» sites accessible only to Tor.

Backdoor.AndroidOS.Torec.a is a variation of the popular Tor-client
Orbot. Attackers have added your code in this application, the Trojan
does not impersonating Orbot, it simply uses the functionality of the

version of OS)

send SMS to the number specified in the command

Tor, it took much more code than for its own functionality.
