Granda Misha malware overview
At the time of writing, Granda Misha's developers were offering this trojan for sale and made promises to add more features in the future. Our research into the promotional material revealed that this malicious program is proclaimed to have the ability of enabling user-level access to an infected device.
Among the advertised features are command execution and loader capabilities. The latter means that Granda Misha could be used to infect systems with additional malware (e.g., trojans, ransomware, cryptominers, etc.).
It also operates as a stealer - hence, this program can extract information from various browsers, e.g., Firefox, Google Chrome, Opera, Brave, Vivaldi, Yandex, Chromium, QQ, and Torch Web. Such functionalities are typically used to acquire victims' financial details (e.g., banking account credentials, credit card numbers, etc.), account usernames/passwords (e.g., social networking/media, e-commerce, online banking, etc.), and other vulnerable data.
Granda Misha's developers claim it can obtain information from communication platforms, FTPs (File Transfer Protocols), and cryptowallets (primarily those designed for Bitcoin). This list includes: Telegram, Gajim, Pidgin, Psi, Psi++, NppFTP, WinSCP, Core FTP, FileZilla, and so forth. Another of its information-stealing features is keylogging - the ability to record user keystrokes.
The advertising also includes a ransomware section detailing a variety of customizable options. Ransomware capabilities include data encryption for ransom purposes. Granda Misha offers several cryptographic algorithms (Curve25519, ChaCha20, and SHA-256), encrypted extension options (no extension, different extension per file, etc.), desktop wallpaper changing, ransom note variants (sixteen languages, alternative communication methods, Windows Volume Shadow Copy deletion, and so on.
To summarize, Granda Misha infections can lead to multiple system infiltrations, permanent data loss, severe privacy issues, financial losses, and identity theft.

The term "trojan" covers a wide range of malicious software. Therefore, the functionalities of these programs can vary drastically. Popular features include (but are not limited to): data extraction, file download, file upload/execution (chain infections), remote access/control, spying (live-streaming/recording the desktop and audio/video via microphones/webcams, keylogging, etc.), and clipboard (copy-paste buffer) data replacement.
We have analyzed many trojan-type malicious programs; Maxtrilha, Ares, Numando, Cinobi, Bizarro, and Ceprolad are just some examples of them.
How did Granda Misha infiltrate my computer?
At the time of research, the Granda Misha trojan was offered for sale online. Hence, how it is proliferated (and used) - depends on the cyber criminals using it. The most common malware distribution techniques involve promotion through dubious download channels, spam mail, drive-by (stealthy and deceptive) downloads, and online scams.
To elaborate on some of these techniques, malicious software can be disguised as or bundled with ordinary programs/media and hosted on untrustworthy download channels, e.g., Peer-to-Peer sharing networks (Torrent clients, eMule, etc.), unofficial and freeware websites, and other third-party downloaders.
Illegal activation tools ("cracks") can cause system infections instead of activating licensed software. Fake updaters infect systems by abusing outdated programs and/or by installing malware.
How to avoid installation of malware?
Caution and vigilance are key to computer safety. Therefore, we recommend downloading from official and verified sources. Programs must also be activated and updated with legitimate tools obtained from official channels. We advise against opening the attachments/links found in suspicious emails and other messages.
The importance of having a reputable anti-virus installed and updated - must be emphasized. We strongly advise using security software to perform regular system scans and to remove 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.

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.
