AppMaster Malware – Distribution Methods
The AppMaster malware is a modified version of a legitimate system utility that is being distributed using some of the common strategies. The security reports read that the main vector so far seems to be a hacker-created website that is designed to advertise a PDF conversion utility. A cross-check has confirmed that there are several different names that the Appmaster malware uses. One of the names it uses as a disguise is “PDF PRO 100” — a tool for converting popular file formats. Various scripts can redirect to the malicious sites — banners, pop-ups, in-line links and etc.
Another popular strategy is to send out SPAM emails — they use phishing tactics which are sent in bulk to the recipients. The malicious operators seek to impersonate messages that are sent by legitimate institutions and popular services.
By itself this particular threat represents a malicious software installer — there are two possible origins:
- Infected Software — The criminals can take legitimate system utilities, their original setup files will be taken by the criminals and modified to include the virus code.
- Malicious App — The application itself can be entirely made by the hackers with the intent of masking as a legitimate system tool.
Another tactic relies on the use of browser hijackers. They are dangerous plugins made compatible with the most popular web browsers and uploaded with fake user reviews and developer credentials. Their description often advertises promises of greatly enhancing their functionality or adding new features. When they are installed most of them will redirect the users to a hacker-controlled page and will also lead to a virus installation.
AppMaster Malware – Activity
The installation of the AppMaster malware will trigger different behavior according to the hackers configuration. One of the first signs of infection is the installation of additional programs — this means that the malicious operators can lead to infections of various types of threats. An example includes the following:
- Ransomware — These viruses are among the most deadly and are designed to encrypt target data with a strong cipher. The victims will be blackmailed to pay the operators for data recovery.
- Trojans — These are viruses that seek to take over control of the victims computers at any given time. They are also particularly useful for extracting files and data that can then be used for identity theft and financial abuse.
- Cryptocurrency Miners — Among the most popular threats are also miners that take advantage of the available system resources in order to carry out complex calculations. When they have successfully completed the malicious operators will be rewarded digital currency for the operations.
- Adware — Various scripts, redirects, pop-ups and banners can be generated in the victims banners. The reason for this is the fact that every viewed or interacted results in profit generation for the operators.
During the virus’s observation the analysts discovered that interaction with the document conversion utility does not actually fulffill the promises. The files are uploaded to a server belonging to a cloud service provider. It will do the conversation for them and offer the installation of a browser hijacker.
The security analysis shows that the Appmaster malware is particularly dangerous as it can use practically any software payload, not just the aforementioned “PDF PRO 100” application. We expect to see other campaigns featuring it as the main code.
