More about the "Dynaseiki Industrial Supplies" email

Cybercriminals behind this email attempt to trick recipients into believing that they have received a quotation letter. Their goal is to trick recipients into clicking the "VIEW" or "DOWNLOAD" hyperlink that is supposed to view or download a list of products and their prices. Those links download a malicious file.

Currently, the type of malware distributed via this email is unknown. Usually, threat actors use such campaigns to spread ransomware, cryptocurrency miners, information stealers, remote access Trojans (RATs), or other malware.

Ransomware encrypts files and demands payment in return for data decryption. Files cannot be accesses/used while they are encrypted. Cryptocurrency miners use computer hardware to mine cryptocurrency. Having a computer infected with such malware affects its performance and consumes more electricity.

Information stealers gather usernames, passwords (or other login credentials), credit card details, and other sensitive information. RATs allow threat actors to access and control the infected devices. Usually, RATs are used to steal information and files, distribute malware, and other purposes.

Malspam campaigns in general

Most emails containing malicious files or links are disguised as important/official letters from legitimate companies, or other entities. The purpose of these emails is to trick recipients into downloading and executing malware. Examples of similar emails are "DHL NOTICE OF ARRIVAL", "CAETANO FORMULA", and "The List Of The Problem".

How did "Dynaseiki Industrial Supplies" infect my computer?

Malware infects computers after users execute it (open a malicious file) by themselves. Typically, emails used to deliver malware contain malicious MS Office or PDF documents, JavaScript files, executable files (like .exe), or archive files (like ZIP, RAR) containing malicious files.

Malicious MS Office documents do not infect computers after opening them until users enable macros commands (enable editing/content). This does not apply to documents opened with MS Office versions released prior to 2010. Those versions do not include the "Protected View" mode.

How to avoid installation of malware?

Do not open attachments and links in irrelevant emails sent from unknown or suspicious email addresses. Download software from official pages. Do not use unofficial pages, third-party downloaders, torrent sites, Peer-to-Peer networks, and similar sources to download software.

Update or activate the installed software using tools provided by the official software developers. Use reputable antivirus software for computer protection. If you've already opened "Dynaseiki Industrial Supplies" attachment, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Types of malicious emails:

Phishing email icon 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.

Email-virus icon 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 email icon 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.

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.
