Sorano Stealer virus removal guide
What is the Sorano Stealer?
Sorano Stealer is malicious software designed to exfiltrate (i.e., steal) various information from an infected system. This malware's primary functions include exfiltration of information stored in browsers and sessions from applications. The stolen data can be misused in various ways. For example, Sorano Stealer's developers offer stolen information for sale. How the malware works and obtained information is used depends on the cyber criminals' modus operandi.
As with the first version of Sorano Stealer, its updated version has also been made available for purchase. One of this malicious program's main functions is stealing browser autofill data, cookies and stored passwords. The malware targets Chrome, Yandex, Kometa, Opera, Orbitum, Comodo, Amigo and Torch browsers, however, it does not affect all of these in the same way. For example, Sorano Stealer cannot exfiltrate passwords from Yandex. Some of this has been rectified in the updated variant. An added feature is for password decryption and exfiltration from Chrome v80 version, but not for its browsing cookies. Another addition are capabilities to steal from the Gecko browser engine (which is used for Mozilla Firefox browser, Thunderbird email client, etc.). According to the listed features in Sorano Stealer's promotional material, it can steal sessions from Discord, Telegram, Skype, Steam and Filezilla. In the new variant, VPN and Jabber are added as targets, as are Skype sessions, however, during research, neither of the versions targeted Skype in the manner advertised. In fact, the updated version steals only Pidgin messaging-client sessions and not those of all Jabber-based (XMPP) communication clients. Sorano Stealer can steal certain cryptocurrency wallets as well. Other features of this malware include exfiltration of text files (.txt) from the desktop and system information, and taking screenshots. While some of the functions promised were missing from the first version of Sorano Stealer, several were implemented in the update. Furthermore, this malicious software contains basic anti-analysis capabilities, such as launch prevention on virtual machines or other "sandbox" environments. Both versions of Sorano Stealer are dangerous. This malicious program can cause financial loss, serious privacy issues, identity theft and other serious problems. If it is known or suspected that a system is infected with this (or other) malware, you are strongly advised to use an anti-virus program and remove it immediately.

PoulightStealer, Neshta, ArkeiStealer and Oski are some examples of other information-stealing malware infections. Malicious programs of this type can target different information, and might also have additional capabilities not associated with data exfiltration. Regardless of how such programs operate, the purpose is identical: to generate revenue for the cyber criminals behind them. Malware infections endanger device and user safety, and therefore immediate removal is crucial.

How to avoid installation of malware
Do not open suspicious or irrelevant emails, especially those received from unknown/suspect addresses. Any attachments or links found in such messages must not be opened, as these files are a potential source of infection. Use only official and varied download sources.

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.

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.
