How to remove the Snake keylogger from your operating system

What kind of malware is the Snake keylogger?

Snake is a malicious program classified as a keylogger. As the classification implies, the primary function of this malware is keylogging. Therefore, Snake infections pose a threat to the privacy/safety of all typed information.

Snake keylogger in detail

Snake malware's main feature is keylogging (records key strokes), however, this program has other functionality as well. It can take screenshots and extract data stored in the clipboard (i.e. copy/paste buffer).

Furthermore, Snake can extract and exfiltrate stored information from certain browsers (e.g. Google Chrome, Mozilla Firefox, Opera, 360, etc.) and email clients (e.g. Mozilla Thunderbird, Microsoft Outlook, Foxmail, etc.). Malicious programs such as Snake are typically used to steal account log-in credentials (i.e. IDs, usernames and passwords) and financial information (e.g. banking account and credit card details etc.).

Communication/Messaging accounts (e.g. social media, social networking, messenger, etc.) are targeted by cyber criminals. Through these platforms, they can ask contacts/friends for loans and proliferate malware (by sharing infectious files) under the guise of the accounts' genuine owners.

Furthermore, should any sensitive/compromising content be found on hijacked data storage accounts, it can be held for ransom under threat of publication and/or sale to the victims' competitors. Accounts that directly deal with finances and/or store financial information (e.g. e-commerce, online money transfers, digital wallet, banking, etc.) are of particular interest, as through them, criminals can make fraudulent transactions and make online purchases.

To summarize, Snake infections can lead to serious privacy issues, financial loss and identity theft. If it is known or suspected that the Snake keylogger (or other malware) has already infected the system, use anti-virus software to remove it without delay.

Malware of this type in general

404 Keylogger, Kutaki, Matiex, Hakops and Cheetah are some examples of other keyloggers. These malicious programs can have a wide variety of dangerous functionality in different combinations.

Common malware types/capabilities include (but are not limited to): download/installation of additional malicious programs, data encryption and/or screen-locking for ransom purposes (ransomware), audio/video recording via integrated and/or connected microphones and webcams, enablement of remote access and control over an infected machine, use of system resources for cryptocurrency mining (cryptominers), and so on.

Regardless of how malware operates, it always poses a threat to device/user safety. Therefore, it is crucial to eliminate all threats immediately upon detection.

How did Snake keylogger infiltrate my computer?

The Snake keylogger is offered for sale online with prices varying from US$25 to $US500 (USD) depending on operation timeframe, and support and range of functionality/customizability. Hence, how it is spread depends on the cyber criminals using it.

Popular malware proliferation methods are via backdoor/loader Trojans, spam campaigns, illegal activation ("cracking") tools, fake updaters and dubious download sources. Some types of Trojans are designed to cause chain infections (i.e. download/install additional malware).

When cyber criminals attempt to distribute malware via malspam campaigns, they send emails that contain malicious attachments or download links for malicious files. Typically, they disguise their emails as official and important. If recipients open the attached file (or a file downloaded via a website link), they cause installation of malicious software.

Cyber criminals commonly attach executable files (.exe), archive files such as RAR, ZIP, PDF documents, JavaScript files and Microsoft Office documents to their emails. Software 'cracking' tools supposedly activate licensed software illegally (bypass activation), however, they often install malicious programs and do not activate any legitimate installed software.

Trojans are other rogue programs that can cause chain infections. I.e., when a Trojan is installed on the operating system, it can install additional malware.

Free file hosting websites, freeware download websites, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, and third party downloaders are examples of other sources that are used to distribute malware. Cyber criminals disguise malicious files as legitimate and regular. When users download and open them, they inadvertently infect their computers with malware.

Fake software updating tools install malicious software rather than updates/fixes for installed programs, or they exploit bugs/flaws of outdated software that is installed on the operating system.

How to avoid installation of malware

Do not trust irrelevant emails that have files attached (or contain website links) and are received from unknown, suspicious addresses. Software should not be downloaded or installed through third party downloaders, installers, unofficial pages or other similar sources/tools.

Use only official websites and direct links. Installed software should never be updated or activated with third party, unofficial tools, since they can install malware. Furthermore, it is illegal to use third party tools to activate licensed software.

The only legitimate way to update and activate software is to use tools and functions that are provided by the official developers. Regularly scan your computer with reputable antivirus or anti-spyware software and keep this software up to date.

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.

Screenshot of a malicious email attachment (MS Exel document) usred to inject Snake keylogger into the system:

Update May 25, 2022 - a new spam campaign proliferating the Snake keylogger has been discovered. The spam emails carried a PDF attachment titled "REMMITANCE INVOICE.pdf". Once opened, the Adobe Reader program displays a request to open a Microsoft Word document.

This file is intentionally named "has been verified. However PDF, Jpeg, xlsx, .docx" - so that the filename would match Adobe Reader's warning. Hence, instead of seeing that the document they're about to open might be malicious - users are presented with a statement that the file was verified, but the following formats may be harmful.

After the MS Word document is opened, the infection chain depends on whether the "Protected View" mode is enabled or disabled. If the mode is active, the infection process begins after users enable the malicious macro commands (i.e., editing/content).

Detailed description of the infection process employed in this campaign can be found in an article on the HP Wolf Security Blog.

Update February 20, 2025 – new version of the Snake keylogger has been discovered. This variant relies on a new anti-detection mechanism wherein the primary payload (Snake) is infiltrated and executed through the use of the AutoIt programming language. Basically, an AutoIt-compiled binary serves as the executable containing Snake – thus, the infection can evade traditional detection measures.

The preferred method for distributing this malware remains to be email spam campaigns. Significantly affected areas include Taiwan, China, Indonesia, Turkey, and Spain.

Update March 26, 2025 – Snake keylogger's design shows a continued emphasis on stealth and anti-analysis. The latest variant is still distributed using the same method – email spam campaigns. Snake malware infiltrates devices through a multi-stage infection chain.

The email attachment is a .IMG (Disc Image Data File) disguised as a PDF document. When this file is opened, it creates a virtual drive to access the data therein. The file within the .IMG is an executable – and with it begins the first stage of the infection.

The executable is a downloader and loader that, upon launch – connects to the attackers' C&C server to retrieve an encrypted payload. In the second stage, a DLL file (Dynamic Link Library) is dynamically loaded into memory. The DLL is likewise highly obfuscated.

The payload (Snake keylogger) is then injected by using the process hollowing technique – wherein a new process is created in a suspended state, and the legitimate memory region is unmapped while malicious code is inserted into the hallowed space prior to the process resuming.

More information on these developments can be found in an article on the Seqrite blog.

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.
