What is the Woody RAT?
Woody is the name of a Remote Access Trojan (RAT). Malware within this category allows remote access and control over compromised machines. Woody is a piece of sophisticated malicious software, and it has a variety of functionalities.
Woody malware overview
The Woody RAT enables remote access/control over infected devices; it can perform a broad range of commands and functions, including those that relate to data gathering, content infiltration and exfiltration.
To elaborate on some of these functionalities - Woody is capable of extracting a wide variety of system data, e.g., operating system version and architecture, computer name, PowerShell information, user accounts and privileges, Network data, running processes, installed anti-viruses, etc.
This trojan also targets personal information. It can gather directory data, i.e., collect file: names, types, formats, creation/modification/access times, size, permissions, etc. The RAT can exfiltrate (download) files as well. Additionally, it is capable of taking screenshots.
Furthermore, Woody has the ability to infiltrate (upload) files and execute them. This means that this malicious program can be used to download/install additional trojans, ransomware, and other malware. The capability to cause chain infections creates another layer of risk associated with the Woody RAT.
What is more, how the data/content obtained through this trojan will be used can vary depending on the information itself and the cyber criminals' goals, which could range from extortion to espionage.
In summary, Woody can cause multiple system infections, severe privacy issues, financial losses, and lead to identity theft. If you suspect that your system is infected with the Woody RAT (or other malware), we highly recommend immediately using an anti-virus and removing this threat.

Remote Access Trojan examples
These trojans are often incredibly multifunctional; their threats and uses are exceptionally varied. However, regardless of a malicious program's versatility or lack thereof - the presence of malware on a system endangers device and user safety.
How did Woody infiltrate my computer?
The Malwarebytes Threat Intelligence team has observed two methods primarily used in Woody's distribution. The earliest instances entailed malicious archive files, while infectious Microsoft Office documents that abuse the Follina vulnerability surfaced later.
These files were named in Russian (not necessarily in the Cyrillic script) and related to security, forms, documentation, and so on. It is highly likely that these malicious files were distributed as either attachments or download links in spam emails.
What is more, malicious software is not spread exclusively via spam mail. Malware is also commonly proliferated through online scams, drive-by (stealthy and deceptive) downloads, dubious download sources (e.g., unofficial and free file-hosting websites, P2P sharing networks, etc.), illegal software activation ("cracking") tools, fake updates, and malvertising (malicious ads).
How to avoid installation of malware?
We advise against opening the attachments and links found in suspicious emails and messages - since that can result in a system infection. Additionally, we recommend using the latest versions of Microsoft Office, especially those released after 2010, as they have the "Protected View" mode that prevents automatic execution of macro commands.
Furthermore, all downloads must be done from official and verified channels. It is just as important to activate and update programs using functions/tools provided by genuine developers, since illegal activation ("cracking") tools and fake updates may contain malware.
It is crucial to have a dependable anti-virus installed and kept updated. This software has to 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.
