AveMaria Trojan – Distribution Methods
The AveMaria Trojan has been identified in a small-sized campaign which doesn’t give out information about the preferred distribution methods. We anticipate that the most popular ones are going to be used:
- Email Phishing Campaigns — The criminals can devise email SPAM messages that utilize phishing strategies in order to coerce the recipients into thinking that they have received a message from a well-known company. The virus files can be delivered directly as attachments or linked in the body contents. Common disguises include software update notifications, patches and etc.
- Malware Web Sites — The criminals behind the threat can create dangerous sites that pose as legitimate and safe pages. Usually the most common ones that are done are download portals, product landing pages, search engines and others.
- Dangerous Documents — This is done by inserting dangerous macros in the most popular document types: spreadsheets, presentations, databases and text files. Whenever they are opened by the victims a prompt will appear asking for the macros to be run. The reason that is quoted is that this is required in order to correctly view the document.
- Dangerous Applications — The hackers can create dangerous installers for software that are popularly downloaded by end users. The hackers typically choose those apps that are most likely to be downloaded and executed by most computer users: system utilities, productivity, anti-virus and creativity suites.
- Browser Hijackers — They represent dangerous plugins which are made compatible with the most popular web browsers. They are frequently uploaded to the relevant repositories and use fake user reviews and developer credentials. The posted descriptions will promise the addition of new features and performance optimizations. Whenever they are installed not only will the AveMaria Trojan be deployed to the victim machines, but also modifications to the web browser settings will be made. This is done in order to redirect the victim users to a hacker-controlled page.
- File-Sharing Networks — The files can be sent over peer-to-peer networks like BitTorrent which are often used to spread both pirate and legitimate content.
Trojans like this one are also well-known to be distributed via direct vulnerability testing. This is done using automated software that use payloads that attempt to find out weaknesses in computer systems.
AveMaria Trojan – Detailed Description
The AveMaria Trojan will immediately start the infection engine as soon as the target machine has been penetrated. It can hook up to existing processes and thus monitor the users actions. The Trojan can access both the applications and the operating system itself even those with administrative privileges. Code injection is one of the most popular techniques used by such malware. It allows the engine to manipulate other programs into running code. This makes it much more difficult for security software and system administrators to detect.
The code analysis shows that a several stage deployment is being done. This is done in order to make it start the different modules in the prescribed order. Some of the example actions that can be started include the following:
- Persistent Installation — By modifying the system settings and certain configuration files the AveMaria Trojan can be set to start automatically each time the computer is powered on. This will override the standard bootup procedure and also disable access to the recovery menus which renders most manual user removal guides non-working.
- Windows Registry Changes — The engine can be instructed to make changes to the Windows Registry by creating ones for itself and modifying those that belong both to the operating system and the third-party installed applications. This can lead to severe performance issues to the point of rendering the computer completely unusable. When the strings that belong to individual programs are modified then certain functions can stop working or unexpected errors can come up.
- Security Bypass — The analysis of the ransomware shows that it can be programmed to block the software that can potentially interfere with the proper AveMaria Trojan execution. This includes all forms of anti-virus programs, firewalls, virtual machine hosts and debug environments.
The main goal of the AveMaria Trojan is to drop various malware threats to the affected hosts. A list of some of the most common ones:
- Ransomware Infections — These viruses follow a typical behavior of targeting sensitive user data based on a built-in list of target file type extensions. The information is processed by a strong cipher and the resulting data is marked with a preset extension.
- Browser Hijackers — These are dangerous plugins which are made compatible with the most popular web browsers. Once installed on the infected computers they will redirect the victims to a preset hacker-controlled page. This is done by changing the following settings: default home page, new tabs page and search engine.
- Trojan Horse Client — This instructs the local client to establish a connection with a hacker-controlled server. This allows the hackers to take over control of the machines, steal files (before any data processing occurs) and take spy on the victims in real-time.
- Cryptocurrency Miners — These small-sized applications or scripts will download a series of tasks that will place a heavy toll on the performance of the computer to the point of rendering it completely unusable. It will affect areas such as CPU, GPU, memory and hard drive space. Whenever one of the tasks is reported as complete the hackers will receive digital currency that will be directly wired to their wallets.
All kinds of other malicious actions can be ordered as well depending on the goals of the hackers.
