Cloud 9 infections lead to the cyber criminals gaining the ability to access/control victims' devices; essentially, it operates as a RAT (Remote Access Trojan). RATs tend to be very versatile, and Cloud 9 is not an exception. It can add compromised machines into a botnet, launch DDoS attacks, steal data from browsers and systems, install additional malicious content/programs, and mine cryptocurrency.
Cloud 9 is commonly distributed through deceptive Adobe Flash Player update websites, and it can appear as a Flash Player extension on Chrome browsers. This malware has been on the market for a while; its been available on hacker forums since 2017 - therefore, it is likely spread using a wide variety of techniques.
Following successful infiltration, Cloud 9 begins collecting relevant data concerning the system and installed browsers. This data harvesting is important for further stages of the infection, as the malware's goal is to inject malicious code and programs into the device - thus assuming full control over it.
Cloud 9 can monitor users' browsing activity, e.g., when a browser is closed, the movements made on a webpage and when one is refreshed, etc. Additionally, the malicious extension can steal Internet cookies. It also has keylogging abilities (i.e., keystroke recording), which can be used to obtain usernames/passwords, credit card numbers, and other vulnerable information.
This extension can run intrusive ad campaigns (i.e., operate as adware). Cloud 9 is capable of stealthily opening webpages on a browser, and this functionality is often used to access malicious sites and further the infection.
As the infection progresses, this malware gains control over the machine - and if the user has admin privileges, they can be abused to create new accounts, access/manipulate/delete data, and so forth - without limitation. Hence, Cloud 9 can operate as a RAT - a type of malicious software that enables remote access and control over devices.
Cloud 9 can obtain the data copied into the clipboard, and this feature is triggered whenever the victim pastes content. The malware can also abuse system resources to generate cryptocurrency (i.e., operate as a cryptominer).
Additionally, Cloud 9 can add infected devices into a botnet, with which it can then launch DDoS attacks and thus disrupt various processes (e.g., websites, services, companies, etc.).
To summarize, Cloud 9 infections can result in severe privacy issues, data loss, hardware damage, significant financial losses, and identity theft.

Malware in general
Malicious software can have a broad range of functionalities, which can be in varied combinations. However, regardless of how malware operates - its presence on a system endangers device integrity and user safety. Therefore, we strongly advise eliminating all threats immediately upon detection.
How did Cloud 9 infiltrate my computer?
Cloud 9 has been observed being proliferated via fake Adobe Flash Player update websites. However, since it has been available on hacker forums for several years - how the malware is proliferated depends on the cyber criminals using it at the time.
Malware is widely proliferated via drive-by (stealthy/deceptive) downloads, online scams, malicious attachments/links in spam emails and messages, untrustworthy download sources (e.g., unofficial and freeware websites, P2P sharing networks, etc.), online scams, malvertising, illegal software activation ("cracking") tools, fake updates, and so on.
How to avoid installation of malware?
We highly recommend being careful with incoming mail. The attachments and links present in suspicious/irrelevant emails and messages - must not be opened since that can result in an infection. We also advise being vigilant when browsing - as illegitimate and malicious material usually appears harmless.
Another recommendation is to download only from official/verified channels. Furthermore, all programs must be activated and updated using functions/tools provided by genuine developers, as illegal activation tools ("cracks") and fake updaters may contain malware.
It is essential to have a dependable anti-virus installed and kept up-to-date. Security 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.

How to remove malware manually?
Manual malware removal is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Combo Cleaner Antivirus for Windows.
If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
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.

Windows 8 users: Start Windows 8 is Safe Mode with Networking - Go to Windows 8 Start Screen, type Advanced, in the search results select Settings. Click Advanced startup options, in the opened "General PC Settings" window, select Advanced startup.
Click the "Restart now" button. Your computer will now restart into the "Advanced Startup options menu". Click the "Troubleshoot" button, and then click the "Advanced options" button. In the advanced option screen, click "Startup settings".
Click the "Restart" button. Your PC will restart into the Startup Settings screen. Press F5 to boot in Safe Mode with Networking.

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.
