"Bank Payment Copy email virus" removal guide

What is the "Bank Payment Copy" scam email?

"Bank Payment Copy email virus" refers to a malware-spreading spam campaign. This term defines a mass-scale operation during which thousands of deceptive/scam emails are sent. The letters distributed through this operation - request recipients to review the payment made to them and confirm it. When opened, the email attachment that supposedly contains the bank payment copy - triggers download/installation of the NanoCore RAT (Remote Access Trojan). Malware of this type is designed to enable remote access and control over infected devices.

Bank Payment Copy malware-spreading email spam campaign

The scam emails with the subject/title "Bank Payment Copy Attached" scam letters state that the sender's Purchase Manager is currently out of office and has instructed them into contacting the recipient. The emails then inform that a payment has been sent to the recipients' company account. They are asked to review the fake bank payment copy and confirm reception. Additionally, should there be any errors, the letters request to notify the sender. Once the attachment is opened, NanoCore trojan's infection chain is jumpstarted.

As mentioned in the introduction, NanoCore RAT can allow cyber criminals access and control over infected machines. Remote access trojans can have a wide variety of malicious functionalities. This malware can have a certain level of control over hardware, software, and content stored or accessed through the compromised device. These trojans can obtain data by downloading it from the system or by using spying abilities, e.g., taking screenshots, recording key-strokes (keylogging) and/or audio/video via microphones and cameras. Furthermore, the malicious programs can extract information from browsers and other installed applications. Data of interest includes: browsing activity, Internet cookies, IP addresses, personally identifiable details, account/platform log-in credentials (i.e., IDs, email addresses, usernames, passwords), and financial data (e.g., banking account details, credit card numbers, etc.). Causing chain infections is another common feature of RATs. Hence, this software can be used to download/install additional trojans, ransomware, cryptocurrency miners, and other malware. To summarize, by trusting the "Bank Payment Copy" scam emails, users can experience system infections, serious privacy issues, financial losses, and even identity theft. If it is known or suspected that NanoCore RAT (or other malware) has already infected the system - an anti-virus must be used to remove it without delay.

"NOTICE OF ACCOUNT CLOSURE FOR AUDIT", "SGBM Email Virus", "OCEANIC PROJECTS Email Virus", and "International Air & Sea Freight Forwarder" are some examples of malware-proliferating spam campaigns. The emails distributed through these large-scale operations - are typically disguised as "official", "urgent", "priority", "important", and similar. The letters may even be presented as messages from legitimate companies, corporations, institutions, organizations, or different entities. Aside from distribution of malicious software, spam campaigns are also used for phishing and other scams. Due to how prevalent deceptive mail is, it is strongly advised to exercise caution with incoming emails.

How did "Bank Payment Copy email virus" infect my computer?

Spam campaigns spread malware via infectious files distributed through them. Virulent files can be attached to and/or linked inside the emails. These files can be in various formats, e.g., archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), Microsoft Office and PDF documents, JavaScript, and so forth. When the files are executed, run, or otherwise opened - the infection chain is initiated. For example, Microsoft Office documents infect systems by executing malicious macro commands. This process begins the moment a document is opened - in Microsoft Office versions released before 2010. Later versions have "Protected View" mode that prevents automatic execution of macros. Instead, users can manually enable editing/content (i.e., macro commands), and they are warned of the potential risks.

How to avoid installation of malware?

Suspect and irrelevant emails must not be opened, especially any attachments or links present in them. It is recommended to use Microsoft Office versions released after 2010. However, spam campaigns are not used exclusively in malware proliferation. Malicious programs are also commonly distributed via dubious download channels (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, etc.), illegal activation ("cracking") tools, and fake updaters. Therefore, it is advised to perform downloads only from official and verified sources. Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers. It is paramount to have a reputable anti-virus/anti-spyware installed and updated. Furthermore, this software has to be used to run regular system scans and remove detected threats and issues. If you've already opened "Bank Payment Copy email virus" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

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 Combo Cleaner Antivirus for Windows.
