What is PO Copy email virus?
Generally, malspam campaigns are used to trick recipients into opening a malicious attachment or a file downloaded via a malicious website. The file then infects computers with malware. In this particular case, cyber criminals send emails with an attached ".7z" archive file, which contains a malicious Microsoft Office document designed to install Agent Tesla.
This email is disguised as a message from Shyamsree Infrastructure PVT LTD, a non-government real estate company. It contains an attachment (the "PO Copy.7z" archive file), which is supposedly a purchase order (PO) copy. In fact, the file contains a malicious MS Office document which installs Agent Tesla.
This malware is capable of functioning as a keylogger and can record keyboard input. Therefore, cyber criminals responsible could steal information such as credit card details, login credentials (usernames, passwords), and other sensitive, confidential data, which could be misused to steal accounts and identities, make fraudulent purchases, transactions, etc.
Agent Tesla is capable of stealing information from a number of web browsers, email clients, messaging clients, VPN and FPT clients, and various download managers. Furthermore, newer Agent Tesla versions can prevent victims from accessing Task manager, System Registry, launching Command Prompt and some other Windows features.
Cyber criminals can use it to take screenshots of the victim's computer screen, and steal Wi-Fi profiles and passwords as well. Possible damage caused by this malware can be avoided by leaving the attachment in this malspam campaign unopened.

Some examples of other malspam campaigns are "Atlas Home Products Email Virus", "Talkline Communications Email Virus" and "Nico International Email Virus". Note that these emails are often disguised official, important messages from legitimate companies and organizations. Other examples of malware distributed in this way include Adwind, TrickBot, and Ursnif.
How did "PO Copy Email Virus" infect my computer?
In this case, Agent Tesla is installed when users extract the attached "PO Copy.7z" archive file, open the Microsoft Office document (named "PO Copy.exe") and enable macro commands (enable editing/content) within the document.
Note that when users open malicious documents with MS Office version released before 2010, they infect computers without having to enable macros commands (these versions do not include "Protected View" feature, and so computers are infected automatically).
How to avoid installation of malware
Software should not be downloaded or installed through third party downloaders, installers, unofficial sites, Peer-to-Peer networks such as torrent clients, eMule or other tools/sources of this kind. The safest way to download files and programs is using official websites and direct links.
Irrelevant emails that contain attachments, web links and are received from unknown, suspicious addresses should not be trusted or opened. Installed software must be activated and updated through tools that are provided by the official developers. Avoid third party, unofficial tools to update or activate software.
Furthermore, it is illegal to use such tools to activate any licensed software. Operating systems should be regularly scanned for threats with a reputable antivirus or anti-spyware suite. If you have already opened "PO Copy Email Virus" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Types of malicious emails:
Most commonly, cybercriminals use deceptive emails to trick Internet users into giving away their sensitive private information, for example, login information for various online services, email accounts, or online banking information.
Such attacks are called phishing. In a phishing attack, cybercriminals usually send an email message with some popular service logo (for example, Microsoft, DHL, Amazon, Netflix), create urgency (wrong shipping address, expired password, etc.), and place a link which they hope their potential victims will click on.
After clicking the link presented in such email message, victims are redirected to a fake website that looks identical or extremely similar to the original one. Victims are then asked to enter their password, credit card details, or some other information that gets stolen by cybercriminals.
Emails with Malicious Attachments
Another popular attack vector is email spam with malicious attachments that infect users' computers with malware. Malicious attachments usually carry trojans that are capable of stealing passwords, banking information, and other sensitive information.
In such attacks, cybercriminals' main goal is to trick their potential victims into opening an infected email attachment. To achieve this goal, email messages usually talk about recently received invoices, faxes, or voice messages.
If a potential victim falls for the lure and opens the attachment, their computers get infected, and cybercriminals can collect a lot of sensitive information.
While it's a more complicated method to steal personal information (spam filters and antivirus programs usually detect such attempts), if successful, cybercriminals can get a much wider array of data and can collect information for a long period of time.
This is a type of phishing. In this case, users receive an email claiming that a cybercriminal could access the webcam of the potential victim and has a video recording of one's masturbation.
To get rid of the video, victims are asked to pay a ransom (usually using Bitcoin or another cryptocurrency). Nevertheless, all of these claims are false - users who receive such emails should ignore and delete them.
How to spot a malicious email?
While cyber criminals try to make their lure emails look trustworthy, here are some things that you should look for when trying to spot a phishing email:
- Check the sender's ("from") email address: Hover your mouse over the "from" address and check if it's legitimate. For example, if you received an email from Microsoft, be sure to check if the email address is @microsoft.com and not something suspicious like @m1crosoft.com, @microsfot.com, @account-security-noreply.com, etc.
- Check for generic greetings: If the greeting in the email is "Dear user", "Dear @youremail.com", "Dear valued customer", this should raise suspiciousness. Most commonly, companies call you by your name. Lack of this information could signal a phishing attempt.
- Check the links in the email: Hover your mouse over the link presented in the email, if the link that appears seems suspicious, don't click it. For example, if you received an email from Microsoft and the link in the email shows that it will go to firebasestorage.googleapis.com/v0... you shouldn't trust it. It's best not to click any links in the emails but to visit the company website that sent you the email in the first place.
- Don't blindly trust email attachments: Most commonly, legitimate companies will ask you to log in to their website and to view any documents there; if you received an email with an attachment, it's a good idea to scan it with an antivirus application. Infected email attachments are a common attack vector used by cybercriminals.
To minimise the risk of opening phishing and malicious emails we recommend using Combo Cleaner Antivirus for Windows.
Example of a spam email:
What to do if you fell for an email scam?
- If you clicked on a link in a phishing email and entered your password - be sure to change your password as soon as possible. Usually, cybercriminals collect stolen credentials and then sell them to other groups that use them for malicious purposes. If you change your password in a timely manner, there's a chance that criminals won't have enough time to do any damage.
- If you entered your credit card information - contact your bank as soon as possible and explain the situation. There's a good chance that you will need to cancel your compromised credit card and get a new one.
- If you see any signs of identity theft - you should immediately contact the Federal Trade Commission. This institution will collect information about your situation and create a personal recovery plan.
- If you opened a malicious attachment - your computer is probably infected, you should scan it with a reputable antivirus application. For this purpose, we recommend using Combo Cleaner Antivirus for Windows.
- Help other Internet users - report phishing emails to Anti-Phishing Working Group, FBI’s Internet Crime Complaint Center, National Fraud Information Center and U.S. Department of Justice.
