Asruex Trojan – Hvordan har jeg det

The Asruex Trojan is a dangerous malware release which has been active since 2015 where the first version was released. Subsequent iterations are launched by different hacking groups and using tacics that are relevant to the chosen end targets at the time of the campaigns. The original distribution of the malware threat was done by sending out malware shortcut data which were sent to the targret users. When these files are opened by the victims a small-sized script (dropper) will download the rest of the Trojan and place it inside image files which are very hard to identify as malware. The end goal is to infect not only a single host, but the whole network.

The latest iteration of the Asruex Trojan has been uncovered in a global attack detected a few days ago. The hackers are using malicious PDF files as payload carriers of the threat. They are being used in phishing-kampagner that can take various forms — both as hacker-made phishing sites or email messages that are sent to the users. They will impersonate services or companies and manipulate the recipients and visitors into downloading and running the prepared documents. Usually they include macros which are prompted to be run by the users. The hacker-created sites will be hosted on similar sounding domain names to the ones which are copied.

Furthermore the new versions of the Asruex Trojan make use of two specific vulnerabilities which the hackers attempt to exploit:

  • CVE-2012-0158 — The ListView, ListView2, TreeView, and TreeView2 ActiveX controls in MSCOMCTL.OCX in the Common Controls in Microsoft Office 2003 SP3, 2007 SP2 og SP3, og 2010 Guld og SP1; Kontor 2003 Web Components SP3; SQL Server 2000 SP4, 2005 SP4, og 2008 SP2, SP3, og R2; BizTalk Server 2002 SP1; Commerce Server 2002 SP4, 2007 SP2, og 2009 Guld og R2; Visual FoxPro 8.0 SP1 og 9.0 SP2; og Visual Basic 6.0 Runtime muligt for fjernangribere at udføre vilkårlig kode via en fabrikeret (en) internet side, (b) Office-dokument, eller (c) .RTF-fil, der udløser “systemets tilstand” korruption, som udnyttes i naturen i april 2012, aka “MSCOMCTL.OCX RCE Vulnerability.
  • CVE-2010-2883 — Stack-based buffer overflow in CoolType.dll in Adobe Reader and Acrobat 9.x before 9.4, and 8.x before 8.2.5 on Windows and Mac OS X, muligt for fjernangribere at udføre vilkårlig kode eller forårsage denial of service (applikationsnedbrud) via a PDF document with a long field in a Smart INdependent Glyphlets (SING) table in a TTF font, as exploited in the wild in September 2010. BEMÆRK: some of these details are obtained from third party information.

For the purpose of infecting as many victim hosts as possible in forthcoming camapigns the hackers may use other tactics as well. Common ones include the inclusion of the installation code in payload luftfartsselskaber or being part of a more complex attack campaign.

Asruex Trojan – What Does It Do

As soon as the relevant Asruex Trojan infection is made the built-in sequence will be run.One of the first actions that are run is the thorough and extensive informationsindsamling which includes the following data: running processes, module versions, file names and disk name strings. All of this is done in order to check whether or not the virus is running inside a debug environment or virtual machine. Dette security bypass check will make the virus run only if there is no such service installed on the computer.

It will proceed by searching for available network shares and installing itself on other devices on the network if possible, note that this can be done with attached removable storage devices as well. Malware of this type attempt to install backdoor modules allowing the hackers to take over control of the hosts, steal data and spy on the victims.
