What is Win32/Skeeyah?

Win32/Skeeyah (also known as Trojan:win32/skeeyah.A) is a trojan-type infection that stealthily infiltrates computers and allows cyber criminals to manipulate infected systems. The presence of this infection can cause various problems, including additional computer infections and privacy issues. Trojans such as Win32/Skeeyah infiltrate computers without users' consent.

Win32/Skeeyah malware

Research shows that after successful system infiltration, Win32/Skeeyah modifies/overwrites certain Windows registry entries. Furthermore, cyber criminals use this trojan to gather various personal information (credit card details, logins/passwords, etc.). These people aim to generate as much revenue as possible. Therefore, they are likely to misuse hijacked accounts in various ways. For instance, they can transfer funds to their own accounts and even borrow money using the victim's email address and social network contacts. Therefore, victims might lose money and get into debt. Since Win32/Skeeyah opens backdoors, there is a high probability that cyber criminals will take advantage and inject additional malware. Backdoors are typically used to proliferate ransomware and cryptominers. In some cases, however, criminals also inject adware and browser hijackers. Most ransomware viruses compromise data (typically, by encryption) and make ransom demands for recovery of files. Cyber criminals often ignore victims, once payments are submitted. Therefore, people are scammed and their files remain encrypted even though the ransom demands are met. Cryptominers misuse system resources to mine cryptocurrency without users' consent. Mining usually takes up to 100% of system resources, and thus it becomes unstable, virtually unusable (it barely responds), is likely to crash. In addition, fully-loaded hardware generates excessive heat. Overheating might cause permanent damage. Adware and browser hijackers are less dangerous - they typically deliver intrusive advertisements, cause unwanted redirects, and gather superficial information (e.g., URLs visited, pages viewed, search queries, IP addresses, etc.). Note that backdoors are also used to proliferate data-stealing trojans. Since Win32/Skeeyah is capable of this function, it is unlikely that criminal will use this tool to spread data-stealing viruses. In any case, Win32/Skeeyah should be eliminated immediately.

There are many trojan-type viruses that share similarities with Win32/Skeeyah including, for example, TrickBot, Adwind, Hancitor, and H-Worm. The developers are different and the behavior of these infections also differs, however, all they all pose a significant threat to your privacy and computer/financial safety. Remove infections such as Win32/Skeeyah immediately.

How did Win32/Skeeyah infiltrate my computer?

Trojan-type infections are often proliferated using spam email campaigns, fake software updaters/cracks and unofficial software download sources. Spam campaigns are used to send hundreds of thousands of emails that contain deceptive messages encouraging users to open malicious attachments (PDFs, Microsoft Office documents, executables, archives, etc.), however, opening them exposes systems to risk of infections - opening attachments distributed via spam email campaigns usually results in various system infections. Fake updaters infect computers by exploiting outdated software bugs/flaws or simply downloading and installing malware rather than the expected updates. Cracks activate paid software free of charge, however, they are often used to proliferate malware, and thus users can often end up infecting their computers rather than gaining access to paid features. Unofficial download sources (peer-to-peer [P2P] networks, freeware download websites, free file hosting sites, etc. are used by developers to present malicious apps as legitimate software. This often tricks users into manually downloading and installing. In summary, lack of knowledge of these threats and careless behavior are the main reasons for computer infections.

How to avoid installation of malware?

The main reasons for computer infections are poor knowledge and careless behavior. The key to its safety is caution. Therefore, pay close attention when downloading, installing, updating software, and browsing the internet. Download apps from official sources only, using direct download links. Third party downloaders/installers often include rogue apps, and thus these tools should never be used. The same applies to software updates. Keep installed applications and operating systems up-to-date, however, use implemented functions or tools provided by the official developer. Never attempt to crack installed applications, since the risk of infection is extremely high and software piracy is a cyber crime. Lastly, have a reputable anti-virus/anti-spyware suite installed and running - this software can detect and eliminate malware before it damages the system. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

To remove this malware we recommend using Malwarebytes 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:

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check 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".

locate the malware file you want to remove

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.

searching for malware file 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. 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 Malwarebytes for Windows.
