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.Kryptik.YKAL is a Windows Trojan with a danger level of 8 out of 10. Trojans pretend to be harmless or arrive hidden inside something else, and then run malicious functions without the user noticing. Kryptik is a detection name used for a broad group of trojans, and YKAL identifies this particular variant. Only one detection of this sample is recorded in the feed data, so it does not look widespread, but it should still be treated seriously.

What the threat does
According to the description, Kryptik.YKAL installs itself stealthily and runs silently in the background while performing malicious functions. It may give attackers complete control over an infected system. It may also covertly delete files and install additional malicious software. The feed text is cut off at this point, so the full list of actions is not available here.
The analyzed sample has these technical traits:
- It is a 64-bit Windows DLL, a native application rather than a .NET one.
- It has no digital signature, no resources, no debug information and no security information.
- It has an exports table and is not packed.
- Of 331 analyzed code blocks, 25 were flagged as potentially malicious, 302 were whitelisted and 4 were unknown.
- It uses low-level system calls from ntdll.dll, including ones for writing files, querying process information, and working with virtual memory.
Direct system calls and memory-related functions are commonly used by malware to work close to the operating system. The feed does not say exactly how this sample uses them, so they should not be read as proof of any single behavior.
How it usually gets onto computers
The feed names these distribution routes:
- Exploiting system vulnerabilities and security flaws.
- Software downloads from malicious websites.
- Email attachments from untrusted sources, usually .exe, .pif, .avi and even .jpg files.
Disguising a malicious file as a video or picture is a typical trick. The file name or icon suggests harmless media, but the file actually runs code when opened.
Risks for the user
- Loss of control: attackers may be able to take over the computer.
- File deletion: documents and other data may be removed without warning.
- Further infections: additional malware may be installed on the system.
Trojans of this kind can typically also be used to steal personal data or credentials, but the feed does not confirm this for Kryptik.YKAL. Because remote control is possible, it is wise to assume that anything stored or typed on the affected computer could be exposed.
Signs of infection
The Trojan is designed to run silently, so there may be no obvious symptoms. These are general signs that are typical for trojans of this type:
- Unexpected slowdowns, crashes or high resource use.
- Files that go missing or programs you did not install.
- Security settings that change or turn off on their own.
- Unusual network activity when you are not using the computer.
Since symptoms may be absent, a full system scan is the most reliable way to check.
How to stay protected
- Install Windows updates and software updates promptly to close vulnerabilities.
- Download software only from official, trusted sources.
- Do not open email attachments from unknown senders, especially .exe or .pif files, or media files that behave strangely.
- Be suspicious of any "picture" or "video" that asks to run a program.
- Keep a reputable real-time security solution active and run full scans regularly.
- Back up important files to a location that is not permanently connected to your computer.
If you suspect an infection, disconnect the computer from the internet, run a full scan with an up-to-date security tool, and remove everything it detects. Afterwards, change your important passwords from a clean device. If the computer still behaves oddly, consider seeking professional help or reinstalling Windows.

Block Information
Block Information
During analysis, EnigmaSoft breaks file samples into logical blocks for classification and comparison with other samples. Blocks can be used to generate malware detection rules and to group file samples into families based on shared source code, functionality and other distinguishing attributes and characteristics. This section lists a summary of this block data, as well as its classification by EnigmaSoft. A visual representation of the block data is also displayed, where available.| Total Blocks: | 331 |

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.- Kryptik.YKAL
Registry Modifications
Registry Modifications
This section lists registry keys and values that were created, modified and/or deleted by samples in this family. Windows Registry activity can provide valuable insight into malware functionality. Additionally, malware often creates registry values to allow itself to automatically start and indefinitely persist after an initial infection has compromised the system.| Key::Value | Data | API Name |
