More about the "Order Trial" malspam campaign

This email is designed to trick the recipient into opening the attached file containing malware. The subject line is "PO 091234 1FCL _OMAN shipment_urgent", implying that it is related to a purchase order and shipment. The body of the email suggests that the recipient has a business relationship with the sender and that there is a new order to be processed.

The message requests that the recipient review the attached purchase order and follow the proper packing list format to avoid any issues. The sender's signature includes contact information, which gives the email an air of legitimacy. However, the email is a fake, and the attached file contains malware.

The file attached to this email is named "PO091234.html" (its name may vary). It is designed to open a page that downloads a malicious .jar file (a package file). This file may be used to deliver ransomware, which encrypts victims' files and demands payment in exchange for the decryption key.

Other types of malware that may be delivered via this campaign include spyware, which can steal sensitive information from infected devices, and Trojans, which can create backdoors into systems and allow cybercriminals to take control. Additionally, malicious attachments and links can lead to the installation of viruses or worms, which can spread throughout networks and cause damage to systems.

Similar emails in general

Emails used to deliver malware often have certain commonalities that make them easy to identify and avoid. They often have a sense of urgency, urging the recipient to take immediate action. They also contain suspicious attachments or links that, when clicked, download malware onto the recipient's computer.

Additionally, they often come from unknown or suspicious email addresses, have misspellings or grammatical errors, and lack personalization or specific details that would indicate a legitimate sender. Examples of such emails are "Hydro Group Purchase Order Email Virus", "DHL Statement Of Account Email Virus", and "Company Contact Email Virus".

How did "Order Trial email virus" infect my computer?

Malware can be delivered to users' computers via email attachments or links, potentially infecting their systems. These attachments can take various formats, such as PDFs, ZIP files, or Microsoft Office documents. They may contain malware that activates upon opening or downloading.

Additionally, clicking on links within emails can redirect users to malicious websites, which could download malware onto their computers.

In this particular case, cybercriminals use a .jar (JAR) file to distribute malware. JAR files are executable archives that contain Java class files and associated metadata and resources. Cybercriminals can take advantage of the Java Runtime Environment's functionality to run Java applets or applications from JAR files on target computers.

Once a user downloads and executes a malicious .jar file, it can run arbitrary code on the target computer, such as installing backdoors or downloading additional malware.

How to avoid installation of malware?

In order to ensure your computer's security, it is important to be cautious when opening email attachments or clicking links from suspicious or unknown email addresses, especially if you were not expecting the email. Keep your operating system, programs, and plugins updated with the latest security updates and patches.

Ensure that your antivirus software is always updated. Download programs only from reliable sources, and avoid downloading from P2P networks, dubious websites, or third-party downloaders. Be wary of ads, pop-ups, and links on untrustworthy websites. If you've already opened "Order Trial email virus" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate 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.
