Modern Android banking Trojans are created by virus writers and sold for serious sums as commercial products via underground Internet platforms. However, the source code of one such malicious application was recently made public on a hacker forum, along with instructions on how to use it. Doctor Web security researchers believe that this may lead to a significant increase in the number of attacks involving Android banking Trojans.
Among the huge variety of Android Trojans, malicious programs that can covertly download mobile software have become widespread. They allow cybercriminals to get rewarded every time one of these programs is successfully downloaded and installed. One such Trojan detected by Doctor Web’s security researchers infiltrates the running process of Play Store and stealthily increases the total number of installs of Google Play applications.
Worm viruses are malicious programs that can replicate themselves but cannot infect executable files. Doctor Web specialists have examined one such Trojan that infects RAR archives and uses the VNC remote access system to spread itself.
