"C.N. FREIGHT & SHIPPING email virus" removal guide

What is the "C.N. FREIGHT & SHIPPING" scam email?

"C.N. FREIGHT & SHIPPING email virus" refers to a malware-proliferating spam campaign - large-scale operation during which deceptive emails are sent by the thousand. The letters distributed through this campaign are presented as quotation requests from C.N. FREIGHT & SHIPPING. It must be emphasized that these scam emails are in no way associated with the genuine C.N. Freight & Shipping company. The goal of this spam campaign is to infect recipients' systems with the GuLoader malicious program, which is designed to cause chain infections.

C.N. FREIGHT & SHIPPING malware-spreading email spam campaign

The fake "C.N. FREIGHT & SHIPPING" emails (subject/title "Request for Quotation (RFQ) #4425"; may vary) inform that the sender is currently in the procurement process. Hence, recipients are requested to provide a quotation. The attached file supposedly contains relevant information and specifications, which the letters ask recipients to review prior to providing the quotation. However, instead of containing the promised data, the infectious attachment initiates download/installation of GuLoader malware - upon opening.

GuLoader's goal is to infect compromised systems with additional malware. The malicious programs infiltrated into devices in this manner can have a wide variety of heinous functionalities, and the functions can be in different combinations. Malware classified as trojans can be capable of: stealing information (e.g., exfiltrating content stored on the system and/or extracting it from installed applications), enabling stealthy remote access and control over the device, spying (recording keystrokes, audio, video, etc.), and so forth. Programs within the ransomware classification operate by encrypting data and/or locking the device (e.g., its screen) - in order to demand payment for decryption/ access recovery. Cryptocurrency miners use system resources to mine cryptocurrency. To summarize, by trusting the "C.N. FREIGHT & SHIPPING" scam emails, users can experience system infections, severe privacy issues, financial losses, and identity theft. If it is suspected/known that GuLoader (or other malware) has already infected the system - an anti-virus must be used to remove it immediately.

"Customer Complaint Report", "All Best Logistics", "Here's your PayPal invoice", "Galp Energia Email Virus", and "International Air & Sea Freight Forwarder" are some examples of other malware-spreading spam campaigns. Deceptive/Scam emails are usually disguised as "official","important", "urgent", "priority", and so on. Aside from proliferation of malicious programs, these mass-scale operations are also used for phishing and other scams. Due to spam mail's relative prevalence, it is strongly advised to exercise caution with incoming emails.

How did "C.N. FREIGHT & SHIPPING email virus" infect my computer?

Systems are infected via malicious files distributed through spam campaigns. Infectious files can be attached to the emails, and/or the letters contain download links of such files. They can be in various formats, e.g., archive (RAR, ZIP, etc.) and executable (.exe, .run, etc.) files, Microsoft Office and PDF documents, JavaScript, and so forth. When virulent files are executed, run, or otherwise opened - the infection chain (i.e., malware download/installation) is initiated. For example, Microsoft Office documents cause infections by executing malicious macro commands. In Microsoft Office versions released before 2010 - this process begins the moment a document is opened. Later releases have "Protected View" mode that prevents automatic execution of macros. Instead, users are asked to enable macro commands (i.e., enable editing/content) and warned of the potential risks.

How to avoid installation of malware?

To avoid infecting the system via spam mail, it is advised against opening suspicious/irrelevant emails - especially any attachments or links found in them. Additionally, it is recommended to use Microsoft Office versions released after 2010. Malware is also distributed through untrustworthy download channels (e.g., unofficial and free file-hosting sites, Peer-to-Peer sharing networks, and other third-party downloaders), illegal activation ("cracking") tools, and illegitimate updates. Therefore, it is important to only download from official and verified sources. Furthermore, all programs must be activated and updated with tools/functions provided by legitimate developers. To ensure device and user safety, it is crucial to have a dependable anti-virus/anti-spyware suite installed and kept updated. This software must be used to run regular system scans and remove detected threats and issues. If you've already opened "C.N. FREIGHT & SHIPPING email virus" attachment, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Malwarebytes for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:

manual malware removal step 4In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Malwarebytes for Windows.
