EnigmaSoft Threat Scorecard
EnigmaSoft Threat Scorecards are assessment reports for different malware threats which have been collected and analyzed by our research team. EnigmaSoft Threat Scorecards evaluate and rank threats using several metrics including real-world and potential risk factors, trends, frequency, prevalence, and persistence. EnigmaSoft Threat Scorecards are updated regularly based on our research data and metrics and are useful for a wide range of computer users, from end users seeking solutions to remove malware from their systems to security experts analyzing threats.
EnigmaSoft Threat Scorecards display a variety of useful information, including:
Popularity Rank: The ranking of a particular threat in EnigmaSoft’s Threat Database.
Severity Level: The determined severity level of an object, represented numerically, based on our risk modeling process and research, as explained in our Threat Assessment Criteria.
Infected Computers: The number of confirmed and suspected cases of a particular threat detected on infected computers as reported by SpyHunter.

Trojan.MSIL.Krypt.EEFG is a Windows Trojan with a danger level of 8 out of 10. Like other Trojans, it pretends to be harmless, or arrives without the user noticing, and then performs malicious actions in the background. The "MSIL" part of its name indicates a program built on the .NET platform. It is listed as related to another detection, MSIL.Krypt.GERE. Our data shows it was first seen on 2026-10-23 and most recently on 2026-11-11, with 5 detections recorded so far.

What the threat does
According to the description, MSIL.Krypt.EEFG installs itself stealthily and runs silently in the background while performing malicious functions. After installation, it may allow attackers to gain complete control over the infected system. It may also covertly delete files, and the description lists further harmful actions.
The analyzed file is a 32-bit .NET GUI executable. It is not packed, has no digital signature, and shows high entropy. It also uses Windows functions that are typically associated with anti-debugging, namely IsDebuggerPresent and NtQuerySystemInformation. Malware commonly uses such checks to detect analysis environments and avoid researchers. It also calls functions that read user-related information, such as the default locale.
The file's version information describes it as "Royal Mint" from "Officina Regalis", with a generic version number of 1.0.0.0. Such details are easy to set to anything, so they say nothing about whether a file is legitimate. Malware often uses ordinary-looking names and descriptions to avoid suspicion.
In behavior analysis, 190 blocks were examined. Of these, 6 were flagged as potentially malicious, 134 were whitelisted, and 50 were unknown.
How it usually gets onto computers
The feed data says this Trojan most often spreads in the following ways:
- Exploiting system vulnerabilities and security flaws.
- Software downloads from malicious websites.
- Email attachments from untrusted sources, usually .exe, .pif, .avi, and even .jpg files.
Files with double meanings or disguised extensions, such as a program made to look like a picture or video, are a typical trick for getting people to open them.
Risks for the user
With a danger level of 8, this detection should be taken seriously. Based on the description, the main risks are:
- Remote control of your computer by an attacker.
- Covert deletion of files.
- Other unwanted activity running quietly in the background.
Trojans of this type commonly also serve as a way to bring in additional malware or to collect personal data. This is typical for the category and is not confirmed specifically for this sample, but it is a good reason to treat any infection as a possible privacy and account-security problem.
Signs of infection
The Trojan is designed to run silently, so there may be no obvious symptoms. Typical warning signs for this kind of threat include:
- Unexpected slowdowns, crashes, or high resource use.
- Files that go missing or change without explanation.
- Unfamiliar programs or processes you did not install.
- Unusual network activity or settings that change on their own.
- Your security software reporting a detection with this name.
Because these signs can have other causes, a full scan is the most reliable way to check.
How to stay protected
- Keep Windows and all installed programs updated so known vulnerabilities are closed.
- Download software only from official, trusted sources, and avoid unfamiliar websites.
- Do not open attachments from unknown senders, especially executables or files whose type does not match what they claim to be. Turn on the display of full file extensions in Windows.
- Be cautious with unsigned programs that you did not expect to run.
- Use a reputable, up-to-date security tool and run regular full scans.
- Keep backups of important files on a separate drive or service that is not always connected.
If you suspect an infection, disconnect the computer from the internet, run a full system scan, and remove anything detected. Then change your important passwords from a clean device. If the computer still behaves strangely, consider seeking professional help.

Similar Families
Similar Families
This section lists other families that share similarities with this family, based on EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same packing and encryption techniques but uniquely extend functionality. Similar families may also share source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and network characteristics. Researchers leverage these similarities to rapidly and effectively triage file samples and extend malware detection rules.- MSIL.Krypt.GERE
