The Beendoor Trojan is a dangerous hacking tool which is well-known by the criminals in the underground communities at least since 2016. It is believed that it is made by a criminal collective based in Pakistan. Ever since it has been used in several targeted attack campaigns. It became famous when it was used in a phishing campaign against Indian government facilities, including military facilities. The attacks are carefully planned as they target such servers.
So far one of the main methods of distribution is the spread of infected documents across all popular formats — text files, spreadsheets, databases and etc. When the users interact with the shown links, pop-ups and other content will redirect to a malicious page or directly launch the virus infection.
The criminals will take advantage of the CVE-2012-0158 exploit — ListView, ListView2, TreeView and TreeView2 controls in MSCOMCTL.OCX in the Common Controls in Microsoft Office 2003 SP3, 2007 SP2 and SP3, and 2010 Gold and SP1; Office 2003 Web Components SP3; SQL Server 2000 SP4, 2005 SP4, and 2008 SP2, SP3, and R2; BizTalk Server 2002 SP1; Commerce Server 2002 SP4, 2007 SP2, and 2009 Gold and R2; Visual FoxPro 8.0 SP1 and 9.0 SP2; and Visual Basic 6.0 Runtime allow remote attackers to execute arbitrary code via a crafted (a) web site, (b) Office document, or (c) .rtf file that triggers “system state” corruption, as exploited in the wild in April 2012, aka “MSCOMCTL.OCX RCE Vulnerability.
The CVE-2012-0158 exploit by nature allows the hackers to run dangerous code directly, create other files on the local machines and load various web content. The most common mechanism employed by the criminals is to redirect the victims to a certain hacker-controlled page which will download a malware to the affected hosts automatically.
As soon as the Beendoor Trojan is installed on the target machine it will allow the criminals to institute various actions against the victims. Some of them include the following:
- Scheduled Task Creation — The Beendoor Trojan can take the form of a XMPP library and inject itself in a service which will automatically start itself as soon as the computer is booted. Some of the services under which the Trojan uses as a mask include the following: ‘wmplayer.exe,’ ‘wmplayer.exe, ‘svchost.exe,’ ‘word.exe,’ and ‘winupdate.exe’.
- Files Retrieval — The Trojan can be configured to automatically harvest certain files or allow the operators to retrieve of their own choice.
- Surveillance — The Trojan allows the hacker to take over control of the computers. This will allow the criminals to spy on the users at any given time and meddle with their systems.
One of the most dangerous aspects of the made Beendoor Trojan infections is the fact that it is very small in size taking just 40 KB. Over the time several modifications to the base engine have been made and not all security solutions can detect its signatures. We anticipate that future versions might also include a security bypass function which will scan for the presence of applications that can block the malware installation: anti-virus programs, firewalls, virtual machine hosts and sandbox environments. Other malicious behavior can be set in future releases. Some of the known signatures so far include the following:

Beendoor – How Did I Get It
The Beendoor Trojan can be spread using a variety of different tactics. There are many variants of it which are spread using various collectives. There may be many versions using the Beendoor name and alternatives as well. This allows the criminal collectives to launch a multitude of attacks bearing different versions of the malware.
One of the main techniques is the coordination of phishing email messages which coerce the victims to interact with the included content. They are designed to appear as legitimate notifications sent from well-known services and companies. The Beendoor Trojan files can be either attached or inserted as text links.
Hacker-made sites that pose as legitimate download portals, search engines and software product pages will scam the users into downloading and running the application. They are generally hosted on domains that sound similar to popular sources and may include self-signed security certificates.
To increase the number of infected victims the criminals can also place the Beendoor Trojan in payload carriers such as macro-infected documents and malware application bundles. They are widely downloaded from the Internet by end users and may be found on file-sharing sites as well like BitTorrent.
Such infections can also be spread via browser hijackers which are dangerous web browser extensions that are usually uploaded to the repositories of the most popular browsers.
Beendoor – What Does It Do
The Beendoor Trojan upon execution will start its infection process as soon as the infection occurs. Its main goal is to start a secure and persistent connection to a hacker-controlled server. It allows the criminals to take over control of the affected computers, steal their data and deploy other threats.
Such malware can execute many different tactics depending on the exact attack campaign. Most of them are used in order to serve as payload carriers for other threats. Popular options are the following:
- Data Theft — The Beendoor Trojan may include an information harvesting ability which is capable of acquiring data that ca directly expose the identity of the victim users.
- Machine Identification — Many similar threats are programmed to extract the list of installed hardware components ,specific operating system environment values and user settngs which are then processed by a special algorithm that will output an unique infection ID that is to be assigned to each different computer.
- Windows Registry Changes — The Beendoor Trojan can create entries for itself in the Windows Registry which can make its removal more difficult. If it edits existing values then serious performance issues can arise. Data loss and errors are a common side effect of this operation.
- Boot Menu Options Modification — Some Beendoor Trojan versions can modify the boot options in order to automatically start themselves when the computer is powered on. By disabling access to these options manual user removal guides can become worthless.
- Data Removal — The engine can be configured to locate and delete files such as system backups, restore files and shadow volume copies. This makes recovery much more difficult and in this case the use of a data recovery solution needs to be used.
Any future Beendoor variants can include other malicious actions as per the hacker’s instructions.
