What is the "Insoorya Express Cargo Shipment Documents" malspam

What kind of email is "Insoorya Express Cargo Shipment Documents"?

We have analyzed this email and determined it is malspam. Disguised as a shipping document update from a freight forwarding company, it carries a malicious Microsoft Excel attachment designed to install malware. This email should be deleted without opening any files it contains.

"Insoorya Express Cargo Shipment Documents" email virus overview

The email poses as a routine message from INSOORYA EXPRESS CARGO, a freight forwarding company based in Chennai, India. It references a shipment with PO number RFQ10930 and claims to share updated documents including a checklist, air waybill, packing list, certificate of conformity, and invoice. The sender also asks the recipient to confirm a colleague received documents shared earlier.

INSOORYA EXPRESS CARGO is a legitimate company and has no connection to this malicious campaign. Cybercriminals are using its name and identity to lend the email an air of credibility. The attached file, Updated Shipping Documents.xls, is a malicious Microsoft Excel spreadsheet.

When opened, Excel displays the file in Protected View - a built-in safety measure warning that files from the internet may contain viruses. If the recipient dismisses that warning by clicking "Enable Editing," hidden macro commands embedded in the spreadsheet run automatically.

The malware distributed through this campaign is currently unknown. Spam mail is routinely used to spread a wide range of threats - trojans (backdoors, loaders, stealers, spyware, keyloggers, clippers), ransomware, banking malware, and cryptocurrency miners.

Opening this file could lead to data or financial loss, identity theft, unauthorized account access, or other serious harm. If the file has already been opened and editing was enabled, a full antivirus scan should be run without delay.

Spam campaign examples

In conclusion, this email impersonates a real freight company to trick recipients into opening a malicious Excel file. Once editing is enabled, hidden macro code activates and begins installing malware - which can steal data, lock files, or cause other lasting damage to the system.

Finance Department Secure Document, Your Cheque Is Ready, and DocuSign - Shared Document are just a few examples of similar malspam we have analyzed. Spam campaigns are used to proliferate all kinds of malware.

How do spam campaigns infect computers?

Spam emails spread malware using malicious attachments or links to compromised pages. Common attachment formats include Microsoft Office documents, PDFs, archives (ZIP, RAR), executables, script files, and disk images. Some of these files launch malware immediately when opened; others need the user to take an extra step, such as enabling macro commands in an Office document.

When an email contains a link, it can redirect the recipient to a fake or compromised page. Such pages either download a malicious file automatically or prompt the visitor to run something manually. The end result in both cases is malware installed on the computer.

How to avoid installation of malware?

Exercise caution with unsolicited emails, particularly those urging you to open attachments or visit links. If an email arrives unexpectedly claiming to carry important documents - especially from a company you have not dealt with - treat it as suspicious and do not open any attachments.

Only download software from official developer websites and authorized app stores. Pirated software, key generators, and cracks frequently serve as distribution channels for malware. Keeping the operating system and all installed software up to date also reduces the risk of infection.

Use a reputable security tool and ensure it is running at all times. If you have already opened the attachment in this email, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate any infiltrated malware.

Types of malicious emails:

Phishing 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.

Sextortion Emails

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.

Frequently Asked Questions (FAQ)

Why did I receive this email?

Spam campaigns are not targeted at specific people. Cybercriminals send identical messages to large numbers of addresses, typically compiled from data breaches, fake registration forms, or web scraping. The fact that you received this email says nothing about you personally.

I have provided my personal information when tricked by this email, what should I do?

If you shared account credentials, change your passwords right away. For any financial or personal data that was disclosed, contact your bank and the appropriate authorities as soon as possible to limit potential damage.

I have downloaded and opened a file attached to an email, is my computer infected?

It depends on the file type and what actions you took after opening it. Excel files (.xls) with macro commands only install malware if the user clicks "Enable Editing." If you clicked that button, run a full system scan immediately.

I have read the email but did not open the attachment, is my computer infected?

No. Reading an email does not cause infection. Malware is only triggered when the user opens a malicious attachment or clicks a malicious link. Your system is safe as long as you did not interact with any files or links in the email.

Will Combo Cleaner remove malware infections that were present in email attachment?

Yes, Combo Cleaner is capable of detecting and removing most known malware. That said, some sophisticated threats hide deep within the system and may be harder to catch. A full system scan is the safest approach to ensure all threats are eliminated.
