How to eliminate Aurora malware from the operating system
Written by Tomas Meskauskas on (updated)
What is kind of malware is Aurora?
Our research team discovered the Aurora malware while looking through hacker forums. Its developers advertise Aurora as a multifunctional piece of malicious software. The program's promotional material states that it operates as a RAT (Remote Access Trojan), botnet, stealer, clipper, and data-encrypting ransomware.
Aurora malware overview
The developers of Aurora offer it for sale and promote this program as highly versatile. To provide a brief overview of the promised features, Aurora is stated to have RAT (Remote Access Trojan) functionality. Malware within this classification is designed to enable remote access and control over infected machines. RATs are typically capable of executing various commands, as well as managing system/user files and data, and installed applications.
Malicious software that operates as a botnet can link up a host of infected systems and use them for malicious purposes such as launching DDoS attacks, sending spam, and so on.
Aurora also has stealer capabilities - meaning that it can extract information from the system and installed apps. Stealers often target browsers, email clients, messengers, cryptocurrency wallets, FTPs, password managers, VPNs, gaming-related software, and so forth.
Aurora's promotional material does list the ability to extract passwords and steal cryptowallets. In addition to this data, information-stealing malware usually targets personally identifiable details, IP addresses (geolocations), browsing and search engine histories, finance-related data (e.g., online bank account log-in credentials, credit card numbers, etc.), and so on.
Aurora also works as a clipper - a type of program that can detect and replace data copied into the clipboard (copy-paste buffer). In most cases, clippers are used to replace cryptowallet addresses prior to outgoing transactions - so that the transferred funds would be redirected to wallets owned by the cyber criminals.
The program's developers state to have added an encryption functionality to it. Hence, Aurora might be used as ransomware, i.e., to encrypt victims' files and make ransom demands for the decryption.
To summarize, Aurora infections may lead to severe privacy issues, permanent data loss, significant financial losses, and identity theft. If you suspect that your system is infected with Aurora (or other malware) - we highly recommend using an anti-virus to remove it immediately.

Regardless of how malicious software operates - its presence on a system endangers device integrity and user safety. Therefore, all threats must be removed immediately upon detection.
How did Aurora infiltrate my computer?
Since Aurora is offered for sale - how it is distributed depends on the cyber criminals using it at the time. Malware is primarily spread using phishing and social engineering tactics.
The most common proliferation methods include: drive-by (stealthy and deceptive) downloads, online scams, malicious attachments and links in spam emails/messages, dubious download channels (e.g., unofficial and freeware sites, Peer-to-Peer sharing networks, etc.), illegal program activation tools ("cracks"), and fake updates.
How to avoid installation of malware?
We strongly recommend downloading only from official and verified sources. Additionally, all programs must be activated and updated using tools provided by legitimate developers, as illegal activation tools ("cracks") and fake updates can contain malware.
We advise against opening the attachments and links present in suspicious/irrelevant emails and messages since that may result in a system infection.
We must emphasize the importance of having a reputable anti-virus installed and kept updated. This software must be used to run regular system scans and to remove detected threats and issues. 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.

Update November 23, 2022 - The Aurora malware has been promoted since April 2022. However, after first few months of the release there was a significant decrease in the amount of Aurora sample's being submitted to malware databases. This indicates that the activity had slowed down. However, hundreds of new samples have been detected in October and November, which means that Aurora is "back into the wild". There are at least 7 known malware distribution teams that take part in spreading Aurora: RavenLogs, BrazzersLogs, DevilsTraff, YungRussia, Gfbg6, SAKURA and HellRide. You can find more information about Aurora's recent activity in this article published by SEKOIA.IO.

Screenshot of a fake nVidia Geforce driver download website (nvidio-geforce[.]site) spreading Aurora malware:
Update April 20, 2023 - Aurora malware has been found to be disseminated through YouTube videos and fake software download websites designed to boost search engine optimization (SEO tags are employed to enhance the ranking of videos in search results). Victims are lured into downloading the malware from counterfeit websites by clicking on links found in YouTube video descriptions, which appear to be legitimate utilities.
The threat actors are leveraging a service that allows them to produce counterfeit websites resembling authentic ones, utilizing comparable URLs, logos, and branding to give the impression of legitimacy. Upon visiting these fake websites, users are tempted to download an application containing malware or provide sensitive personal information to the decoy site.
Update May 25, 2023 - Malicious actors now employ deceptive advertisements to redirect users to a fraudulent Windows security update. The scheme is carefully crafted, utilizing a web browser to display a convincing full-screen animation resembling an official Microsoft update.
The fake security update utilizes a newly discovered loader that evades detection by most antivirus software and malware sandboxes. The payload of the loader has been identified as the Aurora stealer.

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.

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.
