A new type of Android malware has been uncovered in more than 20,000 apps a€“ and it's impossible to remove. The app will then serve ads, which generates money for the hacker.Although their may function is to display ads, their system-level status also lets them gain access to key security details built into Android.
The views expressed in the contents above are those of our users and do not necessarily reflect the views of MailOnline. It is noteworthy that all first versions of the Trojan attacked users only in Russia and CIS countries. The Trojan establishes Internet connection and keeps it active by using Wi-Fi or a transmission channel of mobile network operator.
One of the malware’s key features lies in the fact that it can attack clients of almost any bank in the world. Apart from stealing logins and passwords for user accounts, the Trojan still tries to get information on the user’s bank card information. However, the Trojan is able to perform other malicious functions: to intercept and send SMS and MMS messages, to send USSD requests, to send SMS messages to all contacts from the contact list, to transmit all saved messages to the server, to set a password to the lock screen, and to lock the home screen by using a specially-formed dialog. Users in the following countries suffered most of all: Turkey (18,29%), India (8,81%), Spain (6,90%), Australia (6,87%), Germany (5,77%), France (3,34%), the USA (2,95%), the Philippines (2,70%), Indonesia (2,22%), Italy (1,99%), South Africa (1,59%), Great Britain (1,53%), Pakistan (1,51%), Poland (1,1%), Iran (0,98%), Saudi Arabia (0,96%), China (0,92%), and Bangladesh (0,85%). Backdoors are typically designed to execute cybercriminals’ commands on the infected machine. The Trojan is distributed via a dropper in the form of the Microsoft Excel file with a special macros.
Before connecting to the server, the backdoor collects the following data on the infected computer: its name, version of the operating system, and information about the processor, RAM, and drives. This April was marked by a noticeable increase in activity of aggressive advertising modules—they once again turned out to be the most frequently detected malicious applications. An unwanted program module that is incorporated into the Android applications and is responsible for advertising on mobile devices.
Today, one of the popular way of money making among cybercriminals is to contrive malicious programs that can download and install software picking up its rating.
To solve a sudden problem that that the user had no clue about, the victim, of course, has to install a fraudulent application. If the user decides to download the malicious application, they are redirected to the Google Play store and right to the relevant section in which this app is located. Doctor Web strongly advises Android users to be very careful and not to install dubious applications even if these applications are distributed via Google Play.
April 2016 began with a new version of the Gozi Trojan, which now could create peer-to-peer botnets. However, unlike its counterparts, Trojan.Gozi can also generate peer-to peer (P2P) botnets, which allows the Trojan to transmit encrypted information directly to the infected machines. This Trojan displays fake search results in the browser window and imitates pop-up messages from social networking sites.
A family of malicious programs designed to download other malware to the compromised computer. A family of malicious scripts that are written in JavaScript and designed to redirect users to different (including malicious and fraudulent) webpages. A family of malicious scripts that are written in JavaScript and designed to download and install other malware programs on the computer. A family of Trojans designed to steal passwords and other confidential information stored on the infected computer. During April 2016, Doctor Web added 749,173 URLs into the Dr.Web database of non-recommended sites. To illegally infiltrate computer systems and remote networks, attackers often use software vulnerabilities.
According to the statistics collected by Dr.Web for Android, aggressive advertising modules became the most frequently detected programs among other malicious and unwanted applications in April. Find out more about malicious and unwanted programs for mobile devices in our special overview. At present, Facebook is considered to be one of the most popular social networks not only among ordinary Internet users but also among attackers.
If the user follows the specified link, they are redirected to some webpage whose appearance is identical to the Facebook web design. Online shopping has long become one of the most convenient ways to purchase products or services.
As a rule, this scheme starts from emergence of some online store, which offers its customers to buy expensive electronic goods, photography equipment, garden or construction tools, jewelry, and many other products on a very attractive price. Scammers provide fast delivery of goods to any Russian region and offer to pay for them by using QIWI Wallet, a bank card, POS terminals, or other payment services. Usually, it is rather problematic to track down these scammers because they use voice-over-IP (VoIP) service to organize their underground activity, and fly-by-night companies, stolen documents, and figureheads—to be able to withdraw money from the account. Are often tricked by an unbelievably low price of a product or by attractive benefits that advertised goods or services might have, which sounds too good to be true.
Neglect to look up when a domain of the online store was registered, by using any WHOIS service.
Do not use any online map service for finding the location of the office or a warehouse of the online store to make sure that there is not wasteland or an abandoned factory on this place.
Therefore, Doctor Web strongly recommends to be careful when shopping online and to make purchases only from reliable online stores. Instead of contriving brand new banking Trojans, attackers prefer to modify old versions of popular financial malware programs. This malware, which runs on 32- and 64-bit Windows, is able to carry out a wide range of malicious activities.
The past month showed that virus makers have become more active in their attempts to compromise Apple computers.
For more information about these Trojans and their technical details, refer to the article. A Trojan that can download other malicious programs from the Internet and install them on the infected computer. A Trojan designed to steal login credentials and other confidential information stored on the infected computer, together with Steam user accounts.


During March 2016, Doctor Web added 458,013 URLs into the Dr.Web database of non-recommended sites. New adware Trojan that was preinstalled on a big number of Android mobile devices and was incorporated into some apps developed by well-known companies.
Accomplished analysis of dangerous Trojans that can inject themselves into an Android system process.
The malware masquerades as popular apps, such as Facebook, Twitter and Snapchat, and installs something known as 'troganised adware' onto phonesThe malware works by repackaging legitimate apps from the Google Play store with adware, and then released it to a third-party store.The problem is that the repackaged apps remain fully functional, and so the malware is difficult to detect.
Although this malware may seem outdated, its popularity rating is still high: attackers have made the Trojan even more dangerous and capable of performing ransomware functions. Initially, the Trojan was designed to intercept SMS messages containing one-use bank passwords, to covertly send text messages, and to make phone calls.
At that time, it was spread via spam SMS messages that offered the victim to follow the given link and get familiar with the reply to the announcement posted on the Web.
Therefore, the Trojan is continuously connected to the C&C server and prevents possible malfunctions. To do that, the Trojan checked whether the banking application specified in the Trojan’s configuration file is running.
If the user provides necessary information, it is sent to the server, and virus makers gain full control over the victim’s bank accounts. Thus, cybercriminals create a new template of a fraudulent authentication form and command the Trojan to update its configuration file. If the command is to lock the home screen, the Trojan displays a template of a fake dialog that informs the user that they illegally store and distribute pornography and have to pay for the iTunes Gift Card if they want to unlock the device.
Our analytics registered that the Trojan affected users of more than 200 countries and at least 40,000 mobile devices.
Apart from the Trojan itself, those who buy the Trojan also get the server part together with an administration panel that allows them to manage infected devices.
When the malicious application is registered to autorun, the Trojan removes the original file. Upon a command, the malware can send a particular file or information about the specified folder, to delete or rename a file, to create a new folder, and to take a screenshot and send it to attackers.
Besides, Doctor Web security researchers discovered a new Trojan designed to install various software, together with a Trojan incorporated into more than 190 Android applications. This Trojan infected more than 190 applications that were distributed by at least 6 developers. Depending on the result, the Trojan opens a bogus website with the warning and prompts the user to install the relevant software to solve the problem.
If you want to reduce the risk of your device being infected, Doctor Web strongly recommends you not to download dubious applications and to protect your mobile devices with anti-virus software. Typically, these are entertainment applications such as advice apps, horoscopes, dream-books, jokes, and other information for all occasions which the Internet is flooded with. We have informed Google about this incident but the majority of the programs are still available for downloading.
For each download, fraudsters receive interest under the terms of affiliate advertising agreements. Later this month, cybercriminals started to spread a backdoor for Linux via a hacker utility. In addition, the Trojan is also designed to get remote access to the user’s machine by means of Virtual Network Computing (VNC). In addition to this, the malware can replace advertisements displayed on different Internet resources.
Malicious programs of this family are able to execute intruder-issued commands on infected machine controlled by cybercriminals via the IRC (Internet Relay Chat) text-messaging protocol.
Yet, incorrect configurations of server applications and other programs may pose a more dangerous threat. Its key feature lies in the fact that it infiltrated the system via some hacker utility designed to send out UDP packets to a specified address. In addition, it can scan ports within a specified range of IP addresses, run certain files, send any file to cybercriminals, and execute other functions.
Such modules are often designed not only to display annoying advertisements but also to steal confidential information and to download and install various software, which helps cybercriminals make money from victims.
Doctor Web analytics found out that the Google Chrome plug-in able to send out spam messages has already affected more than 12,000 of Facebook users.
If the plug-in affects the browser, it determines the identifier of the user (UID) when they log on to Facebook and modifies the appearance of the website by removing the Privacy Shortcuts menu located at the upper-right side of the Facebook window, together with other drop-down menus of the social network’s interface. Yet, if another website was used to follow this link, the user is redirected to a blank webpage. Millions of people find it faster to log on to a website to buy what they want rather than stand in a long queue and wait for their turn. To make a profit out of gullible Internet users, attackers implement diverse fraud schemes. Such stores have a big number of positive recommendations published by allegedly happy customers, and its URL is very much alike to URLs of other popular online stores. However, after some time, the website and the phone number become unavailable, and all messages sent by the scammed user to the contact email address are returned.
It is noteworthy that this application is initially designed to send out UDP packets to a specified address. In the third one, the Trojan periodically sends a specific datagram to the server in order to inform that it is still active. However, they can differ from each other by the name under which the Trojans are saved to the system, amount of information about the computer they send to the server, or by a set of commands they can execute. Thus, Doctor Web security researchers discovered a new modification of Trojan.Gozi, a banking Trojan whose source code became publicly available some time ago.
Thus, it can steal information entered by the user into web data forms and perform web injections and keylogging functions.
It downloads a text file from the NASA server, used as a glossary, from the server and modifies it regarding the current date, so that the malware can then generate domain names of its control servers.
However, in March, our security researchers found how files affected by this Trojan could be decrypted.


This malicious program was detected in some popular applications and on several dozens of Android firmwares. Banking Trojans for Android mobile devices are considered to be one of the most dangerous threats for those who use mobile banking software because they run the risk to get robbed by cybercriminals. In fact, all those links redirected the user to scam websites that distributed the malicious application under the guise of a benign program.
The number of applications the Trojan monitors can be different, but Doctor Web specialists have already found about 100 of such applications. When the Trojan detects that one of them is running, it immediately displays a phishing form of Google Play payment service settings. The archive consists of an executable file, which has a valid digital signature registered to Symantec, and a dynamic library, in which all the main functions of the Trojan are implemented. After that, the Trojan gathers more detailed data on the computer’s drives, which is sent to cybercriminals, together with the kelogger file. To ensure its downloading, the Trojan displays this website every 2 minutes, which makes it almost impossible to use the device normally. Besides, security researchers detected the intensified activity of Internet scammers who have already tricked a big number of gullible users by creating fake online stores.
Moreover, upon a command, the Trojan can run the SOCKS proxy server and download and install various plug-ins. In April, Doctor Web specialists discovered some misconfiguration of hardware belonging to a large company that supplies DNS and web hosting services. It means that the Linux user, in their attempts to attack a server, fell victim to the Trojan. What is more, the Trojan adds all the victim’s friends on Facebook to the post so this message is published on their walls too. Yet, our specialists recommend you to pay careful attention when installing extensions for the browser even if they are offered by such a popular website as Facebook. Today, almost anything can be purchased online—starting from food to electrical goods. In this paper, we are going to focus on one of them that is quite popular on the Russian Internet judging from the number of people affected by it. In addition, these fraudulent websites contain such standard information as their office address, a contact number (answered by a dispatcher), and a founding company’s name. In several days, the same shop with similar range of goods but with a different name and URL emerges on the Internet. In addition, while the Trojan is being installed to the system, the contents of the iptables utility is cleared. According to Doctor Web analytics, this Trojan is presumably in process of development, because its new modifications appear on a regular basis. Dr.Web for Linux successfully detects all these malicious programs, so they do not pose any threat to our users. Besides, our specialists found a new malware program for Android that attackers incorporated either into some popular apps or into firmware of Android mobile devices.
To read more about the Trojan, and learn what actions should be taken if your computer is infected by this malware, refer to the news article. In particular, if the user launched Google Play or online banking applications developed by several well-known Russian banks, the Trojan displayed a fraudulent input form on top of the running application. The identifier and other technical details are sent to the server, where the infected device is registered. If the user agrees to install the program, it is redirected to the relevant Google Play section. If the necessary application is installed on the device, the Trojan shows another fake warning, for example, about battery malfunction.
In addition, numerous online stores offer affordable prices, fast delivery, and a wide variety of payment methods.
Yet, it is noteworthy that all of them are created using one and the same website template.
However, it can also download, install and run various software, and transmit confidential information to the server. The information about the bank card entered by user was immediately sent to cybercriminals. Once launched, this file loads the malicious library into the memory of the infected computer.
These domains can be used to organize internal non-public servers, version control systems (VCS), bug trackers, various monitoring services, wiki resources, etc.
However, not only potential customers take full advantages of online shopping but also cybercriminals do to conduct their illegal activity.
Then it prompts the user to grant it root privileges, without which its operation is impossible. The server sends an encryption key, information about the server to which requests should be sent, and a port number. Later in March, more than 100 Google Play apps were found to contain an advertising spyware. Having this domain list, attackers can easily examine the network of a potential victim in order to find vulnerabilities. Such flood programs are often able to execute additional covert functions—for example, download other dangerous applications from the Internet. This script is responsible for display of advertisements in the browser window and collects the user’s Web search queries of several search engines.
Moreover, Doctor Web specialists carried out the examination of dangerous Trojans able to inject themselves into Android system process and processes of running applications.
