More_eggs Malware

Also Known As: More_eggs trojan
Type: Trojan
Damage level: Severe

What is More_eggs?

More_eggs is high-risk trojan that opens 'backdoors' and allows cyber criminals to manipulate the system. This virus is typically proliferated using spam email campaigns. Specifically, criminals send fake job offers and attempt to trick recipients into opening malicious attachments (PDF/Microsoft Office documents) or links to websites that trigger download of other similar docs.

More_eggs malware

Written in JavaScript, More_eggs is an infection that allows cyber criminals to perform various tasks on the system. They can download and run portable executables, delete files and startup entries, and run shell commands. These are just some examples from the entire function list. Trojans like More_eggs can be a significant threat to users' privacy and computer safety.

These trojans are often used to inject systems with additional malware, such as data-tracking trojans, ransomware, cryptominers, and so on. Data-tracking infections record keystrokes, saved logins/passwords, banking details, and other similar personal data. Cyber criminals attempt to generate as much revenue as possible.

Therefore, they can misuse hijacked accounts to steal victims' savings and even identities. Ransomware compromises data (usually  by encryption) and makes ransom demands in exchange for recovery of the system. Note that cyber criminals cannot be trusted. Whatever the cost, never agree to pay, since you will be scammed.

Cryptomining applications misuse infiltrated systems to mine cryptocurrency without users' consent. Cryptomining can take up to 100% of system resources, thus making the system unstable (it can crash) and virtually unusable (it barely responds). Furthermore, fully-loaded hardware generates excessive heat.

Therefore, within certain circumstances (e.g., high room temperatures, bad cooling systems, etc.), system components can overheat and be permanently damaged. These are the most popular infections distributed via trojans, however, many others can infiltrate your computers (e.g., adware, browser hijackers, etc.).

You can read more about common computer infections in this article. In any case, the presence of More_eggs might lead to high-risk computer infections, serious privacy issues, and financial/data loss.

There are dozens of trojan-type viruses that share similarities with More_eggs including Cobalt Strike, IcedID, and Brushaloader

These are just some examples from a long list. Although the developers and functionality differ slightly, all of these viruses are capable of damaging the system and causing a number of privacy-relating issues. Therefore, eliminating infections like More_eggs is extremely important.

How did More_eggs infiltrate my computer?

As mentioned above, More_eggs is distributed using malicious PDF and Microsoft Office documents that are proliferated using spam email campaigns. Cyber criminals send fake job offers encouraging recipients to open attached links/files.

Note that criminals who proliferate this malware do not blindly send hundreds of thousands of emails to random people - they target certain companies and their employees. In most cases, the entire campaign consists of two emails. The first one is typically sent through LinkedIn direct messaging.

The sender claims to be a staff member of a company and offers the recipient a job position. Around one week later, the recipient receives another email with a similar message stating that she/he was contacted and that this is a reminder of the existing offer. Depending on the email, the recipient can receive various attachments.

If the attachment is a link, it leads to a fake website (a replica) of the original company site (of which sender claims to be staff member). Once opened, this site immediately triggers download of a malicious PDF/MS Office document. In some cases, these documents are compressed to a password-protected archive and simply attached directly to the email.

In any case, for More_eggs to infiltrate the system, users must manually open these files. Malicious documents contain macros designed using the Taurus Builder or VenomKit. Opening these files and granting permission to execute macros leads to infiltration of More_eggs malware.

How to avoid installation of malware?

To prevent these infections, be very cautious when browsing the internet. Never open email attachments that are irrelevant or received from suspicious/unrecognizable email addresses. Bear in mind that criminals send various deceptive emails that offer products or services free of charge. For example, emails claim that the user has won a lottery, received a package, and so on.

Do not be tricked. Have a reputable anti-virus/anti-spyware suite installed and running, since these tools can detect and eliminate malware before it damages the system. Use 2010 or a newer version of MS Office, since it is implemented with "Protected View" mode, which prevents malicious documents from executing macros automatically.

The main reasons for computer ifnections are poor knowledge and careless behavior - the key to safety is caution. If you believe that your computer is already infected, 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.
