How to eliminate MassJacker from infected systems

What kind of malware is MassJacker?

MassJacker is a cryptojacking malware. The purpose of this malware is to steal cryptocurrency. It is likely distributed and utilized by multiple threat actors, suggesting that MassJacker may operate as a malware-as-a-service (MaaS). Users who suspect their computers may be infected should immediately eliminate the malware to avoid monetary loss.

More about MassJacker

MassJacker is a stealthy malware designed to hijack cryptocurrency transactions by intercepting and replacing copied wallet addresses with attacker-controlled ones. This tactic, known as clipboard hijacking, tricks victims into unknowingly sending funds to the attacker instead of their intended recipient.

If the cryptocurrency has already been sent to the attacker's wallet, it is nearly impossible to recover. Cryptocurrency transactions are irreversible by design, meaning that they cannot be canceled or retrieved once the funds leave the victim's wallet. This makes MassJacker particularly dangerous.

Also, MassJacker uses advanced techniques to avoid detection. It obfuscates its code, manipulates functions during runtime, and hides instructions in a custom virtual machine. It also scrambles code logic, encrypts its payloads, and hides malicious code in DLL files. With anti-debugging checks and memory injection, it makes analysis and detection very difficult.

It is worth noting that MassJacker shares similarities with MassLogger, a type of malware that steals login information, which suggests they may have been created by the same developers or are part of a malware service used by different threat actors.

Conclusion

In conclusion, MassJacker is malware that uses clipboard hijacking to redirect cryptocurrency transactions to attacker-controlled wallets. Successful operations can result in significant monetary losses. It is important for both individuals and organizations to stay vigilant and implement robust security measures to mitigate the risks posed by such threats.

How did MassJacker infiltrate my computer?

The infection starts on a website that claims to offer pirated software but actually tricks users into downloading malware. For MassJacker, this process begins with a command script and a PowerShell script designed to download three files. One of these files is Amadey, a known botnet, and the other two are versions of the same malware designed for different computer systems.

The malware then uses a tool called PackerE, which downloads an encrypted file, PackerD1. This file uses different tricks to avoid being detected by security tools. After that, PackerD1 loads another file, PackerD2, which contains the MassJacker payload. Finally, PackerD2 injects MassJacker into a process called InstalUtil.exe, allowing the malware to run undetected.

How to avoid installation of malware?

Only download software from trusted sources, like official websites or well-known app stores. Never use other sources and do not download pirated software, cracking tools, or key generators. Never click on links or open attachments in suspicious emails, especially those from unknown senders.

Do not click op-ups, ads, or links on questionable websites and do not agree to receive notifications from such pages. Always keep your operating system and software up to date, and use a trusted security tool to perform regular scans for extra protection.

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.

How to remove malware manually?

Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows.

If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:

If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:

Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:

Restart your computer into Safe Mode:

Windows XP and Windows 7 users: Start your computer in Safe Mode. Click Start, click Shut Down, click Restart, click OK. During your computer start process, press the F8 key on your keyboard multiple times until you see the Windows Advanced Option menu, and then select Safe Mode with Networking from the list.

Extract the downloaded archive and run the Autoruns.exe file.

In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.

Check 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".

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.

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.
