What is "Supreme Court Email Virus"?

The "Supreme Court" email, is a deceptive letter designed to proliferate the AsyncRAT (Remote Access Trojan). This scam email is disguised as a notice of a new filing from the Supreme Court. The malicious file attached to the letter is presented as containing important information concerning the filing. If this file is opened, it initiates the infection process of AsyncRAT malware.

Fake Supreme Court malware-spreading email spam campaign

The fake "Supreme Court" letter states that in accordance to the "Supreme Court of Judicature Act 1873", by powers of Investiture, recipients are informed of a new filing. The case is specified as "Case No: 201605644-45 A2". This requires the attention of the recipients' firms. Relevant information is supposedly encompassed in the attached PDF document. Recipients are given a deadline to provide specific information, which is listed in the document. It must be emphasized that these "Supreme Court" scam emails claim is false and they must not be trusted. If the virulent file is opened - it will trigger the infection process (i.e. download/installation) of AsyncRAT. Remote access trojans enable remote access and control over the infected device. These malicious programs can have various abilities/functionalities, which allow a likewise broad range of potential misuse. Some of the main purposes of AsyncRAT is stealing information and causing chain infections (i.e. downloading/installing ransomware, cryptominers and other malware). Therefore, AsyncRAT can cause various system infections, financial losses, severe privacy issues and identity theft. If it is known or suspected that AsyncRAT (or other malware) has already infected the system, an anti-virus must be used to eliminate it immediately.

Deceptive/Scam emails are distributed by the thousand, during large scale operations termed "spam campaigns". "U.S Department of Labor", "BBVA Email Virus", "Polícia de Segurança Pública" and "Apex Enquiry Email Virus" are a few examples of other malware-spreading spam campaigns. The letters are usually presented as "official", "important", "urgent" and similar; they can even be disguised as mail from legitimate institutions, organizations, companies, businesses, service providers, and so on. Spam campaigns can also be used for phishing and other scams. Regardless of what these emails claim, request or demand, the end-goal is the same - to generate revenue for the cyber criminals / scammers behind them.

How did "Supreme Court Email Virus" infect my computer?

Systems are infected through virulent files, distributed via spam campaigns. Infectious files can be attached to the deceptive/scam emails, alternatively the letters can contain download links of them. These files can be in various formats, such as: archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), Microsoft Office and PDF documents, JavaScript, etc. When malicious files are executed, run or otherwise opened - it jumpstarts malware download/installation. For example, Microsoft Office documents infect systems by executing malicious macro commands. In MS Office versions released before 2010 this process begins automatically. The newer versions request users to enable macros (i.e. to enable editing/content); hence, the infection process is only initiated after the macro commands are enabled.

How to avoid installation of malware?

To avoid malware proliferated through spam campaigns, it is advised not to open suspicious and/or irrelevant emails, especially attachments or links found in them. It is recommended to use Microsoft Office versions released after 2010. These versions have "Protected View" mode, which prevent infection processes being initiated upon a virulent document being opened. Other popular distribution methods of malicious programs include - untrustworthy download channels (e.g. unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders), illegal activation tools ("cracks") and fake updaters. Therefore, it is important to always use official/verified download sources, activate and update programs with tools/functions provided by genuine developers. To ensure device integrity and user safety, it is crucial to have a reputable anti-virus/anti-spyware installed and kept updated. This software must be used to run regular system scans and to remove detected/potential issues. If you've already opened "Supreme Court Email Virus" attachment, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

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.

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.
