The ACbackdoor Trojan is a malware threat which is effective against both Windows and Linux computers. There is no information available about the hacking group behind it. It is very possible that they are a very experienced collective as distinct distribution campaigns are being made for the two operating system variants. According to the available information the Linux version appears to be more advanced than the Windows one.
The version for the free operating system is distributed on hacker or hacker-controlled web servers, presumably using phishing tactics. The criminals will host these sites on domain names that sound very similar to well-known companies or services. Usually this will include stolen content and self-signed security certificates that will leave a sense of safety and legitimacy in the visitors. Various elements can be fake including boxes, interactive scripts and etc.
The Windows version depends on the Fallout Exploit Kit which relies mostly on bulk sending of email messages. They are designed to appear as being sent by services or companies that the recipients might know. By including the virus ACbackdoor Trojan attached files or links the infection will start.
Apart from these techniques there may be other tactics considered:
- Virus Code Carriers — The hackers can embed the necessary code in both documents an executable files. The documents can be of all popular file formats. On the other hand the executables files are almost always app installers of popular software which is often downloaded by the users.

ACbackdoor Trojan — Capabilities
When the ACbackdoor Trojan is installed and run on the affected device it will start a sequence of dangerous components. The exact number and type of modules depend on the local system conditions or specific hacker instructions. One of the first modules is the information gathering one which is responsible for the collection of valuable system data — details about the hardware parts, preferences and operating system conditions.
Depending on the operating system it will use different mechanisms which will cause boot options changes that will start the virus when the computer is started. This can be done by modifying the initrd scripts found within the init system on Linux and the Windows Registry for Microsoft Windows.
Future versions of this Trojan can include an expanded functionality which can block access to the recovery boot options. This means that the users will not be able to follow some manual user recovery instructions and will need to use a quality anti-spyware solution that will be capable to fully restore the computer.
What’s important about this virus sample is that it will also initiate a security protection module by masking itself as a common Windows service, part of the Windows Defender protective suite on Microsoft’s operating system. This is done by manipulating the system into thinking that the malware files are part of this system. On Linux it will mask itself as an Update Notifier.
As it is a Trojan by classification it can be programmed to conduct common actions that are often launched by this type of malware:
- Surveillance — The main engine will establish a secure and persistent connection to a hacker-controlled server allowing the hackers to access and monitor the user interactions of the victims.
- Code Execution — The ACbackdoor Trojan can be programmed to start certain commands or download and run other malware. Popular examples are cryptocurrency miners and ransomware.
- Automatic Updates — Some of the malware variants can automatically poll the server and update themselves with a newer release.
