What is Masad?

Masad Stealer is malicious software that, once installed, allows cyber criminals to steal various information/data. Its basic version is free, however, cyber criminals can purchase a 'full version' with more features for $85. Masad Stealer is available for download on hacking forums. Having a computer infected with this malware can lead to serious problems. Therefore, if there is any reason to believe that Masad Stealer might be installed on your system, remove it immediately.

Masad malware

Masad malware is mainly used to steal information stored on browsers (including passwords), cryptocurrency wallet data, and various files. It can also be used to record system information, lists of installed software and running processes, and to take screenshots of the Desktop, steal Steam files, Discord and Telegram data, and FileZilla files. Masad is capable of stealing browser data, including autofill entries. In summary, cyber criminals can use this malware to steal logins, passwords of various accounts and credit card information, and then make fraudulent transactions, purchases, proliferate malware through the victim's email or social networking accounts, and so on. Furthermore, it can be used to replace cryptocurrency wallets that are saved on the clipboard with those used by cyber criminals. In this way, victims might inadvertently transfer cryptocurrency to cyber criminals by pasting replaced wallet addresses. In addition, cyber criminals can use Masad to steal files stored on the victim's Desktop. For example, they could steal text files that might contain personal details (logins, passwords, banking information, and so on). Stolen Steam files can be used to steal Steam accounts and make purchases through them. As a channel to exfiltrate data stolen with Masad Stealer, cyber criminals use Telegram - all stolen details are sent to them through Telegram, which they use as a Command and Control channel. In summary, this malware can be used to steal a wide range of sensitive data. Typically, victims who have computers infected with this malware experience financial loss, problems with privacy, identity theft, and other serious issues.

Other examples of information-stealing malware include Krypton, Laturo, and Qulab. Typically, cyber criminals use this malware so steal as much sensitive information as possible and them misuse it to generate revenue in various ways. People often download and install software of this type unintentionally and are unaware of its presence until they start to experience various problems.

How did Masad infiltrate my computer?

Research shows that Masad is distributed by disguising it as legitimate tool/software. To proliferate it, cyber criminals might use various unofficial websites, third party installers (or downloaders), Peer-to-Peer networks, free file hosting or freeware download web pages, and so on. People who open files downloaded from these channels risk installing malware such as Masad. It can also be proliferated through various unofficial activation and/or 'cracking' tools (which supposedly activate installed software free of charge). Cyber criminals often proliferate malware through emails: they send messages with files attached that, if opened, install malicious software. Typically, they attach PDF or Microsoft Office documents, executable files (.exe), ZIP, RAR and other archive files, JavaScript files, etc. Furthermore, malware can be distributed through unofficial updating tools that install malicious programs rather than updating any software, or they exploit bugs/flaws of software already installed on the operating system.

How to avoid installation of malware

Avoid using third party software downloaders/installers, unofficial websites, Peer-to-Peer networks, and other such tools to download files or programs. They should be downloaded from official web pages and via direct links. Update installed software using implemented functions or tools provided by official software developers. Attachments or web links presented in irrelevant emails should not be opened, especially when they are sent from unknown/suspicious email addresses. Software 'cracking' tools are illegal and often cause computer infections - they should not be used. To protect systems from malware attacks, regularly scan them with reputable anti-spyware or anti-virus software and ensure that it is up-to-date. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes 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 Malwarebytes for Windows.
