Asruex

Asruex Description

The majority of users on the Internet tend to neglect updating their software and their operating systems. It may be a tedious task to keep all your applications up to date, but it is necessary if you want to keep malware away from your system. Since there are so many people who fail to do this, cyber crooks have tailored special malware targeting systems running outdated software or outdated operating systems.

Exploits Almost Decade-Old Vulnerabilities

This is the case with the Asruex backdoor Trojan. The Asruex Trojan has been pestering users for years. If this threat manages to infiltrate your system, it has the full capabilities to gain complete control over your PC. What is even worse is that cybercriminals appear to have developed a new, updated variant of the Asruex backdoor Trojan. This strain of the Asruex Trojan takes advantage of vulnerabilities in outdated versions of common applications like Microsoft Office, Adobe Reader, and Adobe Acrobat. These known vulnerabilities are sometimes about ten years old, but there is still a large swab of people who are running this outdated software.

Propagation Method

The propagation method employed by the authors of the Asruex Trojan is spam email campaigns. The emails would contain a macro-laced Microsoft Word file or a PDF. Once the user opens the attachment, they are asked to approve the use of macro scripts. If they fall for this trick and give the permission requested they will trigger the downloading and subsequent execution of the Asruex backdoor Trojan.

Self-Preservation and Persistence

As a self-preservation technique, the Asruex Trojan is capable of distinguishing normal computers and sandbox environments. It is capable of doing this by scanning Registry entries and configurations, which can indicate the presence of software used for malware debugging. When the Asruex backdoor Trojan confirms that it has infiltrated a regular system, it will gain persistence by tampering with the Windows Registry. Next, the Asruex Trojan will establish a connection with the attackers' C&C (Command & Control) server.

Capabilities

Once these steps are completed, the Asruex backdoor Trojan will be able to:

  • Collect information.
  • List services and processes that are running.
  • Download files.
  • Upload files.
  • Execute files.
  • Browse files.
  • List files.
  • Modify files.
  • Plant additional threats.

Users need to understand how crucial it is to keep their software up-to-date because otherwise, they just serve their systems and their data on a silver platter to whoever wishes to take advantage. Also, they should make sure to download and install a legitimate anti-virus software tool to keep their systems secure.
