ACM_SHENZ.A
Posted: December 6, 2013
Threat Metric
The following fields listed on the Threat Meter containing a specific value, are explained in detail below:
Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.
Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.
Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.
Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.
% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

ACM_SHENZ.A is a backdoor Trojan that conceals itself as a benign file for computer-aided-design products, which may be an attempt at targeting business industries – or simply an effort to use an obscure file type that casual PC users wouldn't recognize. No matter what its overarching goals are, ACM_SHENZ.A is a high-level PC threat that takes over administrative privileges to compromise the system, including opening a backdoor connection that could allow for any number of additional attacks. Along with all of these attacks, ACM_SHENZ.A doesn't show any major signs of being visibility throughout the duration, and malware researchers urge any potentially affected PC user to use competent anti-malware tools for finding and deleting ACM_SHENZ.A.
From Computer-Aided-Design to Trojan-Aided-Destruction
ACM_SHENZ.A, with a disguise less obvious than that of a fake JPEG file, hides itself as an .FAS, which is specific to AutoCAD software. AutoCAD is a popular option for private sector companies related to architectural design, automobiles and various types of heavy industry, and ACM_SHENZ.A's choice of a disguise may be influenced by its intended targets. On the other hand, you don't need AutoCAD software installed to be endangered by ACM_SHENZ.A, which is more than capable of infecting PCs without this software – as long as you're careless enough to open the original installer.
When you've unwrapped the questionable gift of ACM_SHENZ.A, your PC may undergo various changes, all of them intended to harm its security. As far as malware researchers are concerned, the most threatening of these are as follows:
- The creation of a specialized user account for ACM_SHENZ.A that has administrative privileges. This may let ACM_SHENZ.A infections have theoretical access to critical system features and settings, such as the capability to install software.
- Opening network ports that may allow criminals to have remote access to your computer. The ports opened by ACM_SHENZ.A may let these criminals exert control over file transfers, serial ports and printer devices, among other things.
- Modifying hard drive settings (that may include removable drives, such as those used by USB devices and DVDs) to grant full network access to them. Naturally, this attack has an obvious synergy with the aforementioned backdoor connection.
Don't Let ACM_SHENZ.A Make You Look Like a Cad
Although ACM_SHENZ.A's existence is a fair reminder that business places often are recurring targets for PC security-disabling attacks, ACM_SHENZ.A also may be used for a second theme: letting other PC users know how risky it is to open a file type that they don't recognize. Because of this constant risk, malware analysts always recommend displaying file types when possible, and avoiding opening files from potentially unsafe sources (such as e-mail attachments) without verifying their safety beforehand. Like most backdoor Trojans, ACM_SHENZ.A may be an access point between threat designers and your personal computer, but ACM_SHENZ.A is an access point without easily identified features or symptoms.
On a lighter note, most qualified anti-malware products should find removing ACM_SHENZ.A to be well within their capabilities. You also should check to make sure that unreliable operating system accounts and other traits of ACM_SHENZ.A infections are removed along with its software. ACM_SHENZ.A-opened ports should be closed to prevent any future access by criminals, and if all of these steps are done promptly, your PC shouldn't lose much, if anything from the experience.
