If your computer becomes infected with malware, you may notice it immediately. Malware often goes undetected for a prolonged period. Whether it’s a virus, trojan, worm or ransomware, it may conceal itself on your computer while waiting for the perfect opportunity to strike. You can still scan your computer with antivirus software, but it may or may not catch the malware. Hackers often conceal malware using file binders. To learn more about file binders and how they work, keep reading.

What Is a File Binder?

A file binder is a type of software that’s designed specifically to join two or more files together. Files, of course, are typically separate from each other. You can download and open each file individually. A file binder, however, will merge or “bind” multiple files into a single computer.

How File Binders Work

File binders are software-based utility tools. They are used exclusively for malware; there are legitimate applications for file binders as well. You can launch a file binder, after which you can add two or more files to it. The file binder will then join the files together while subsequently generating a new file. The new file will contain all of the joined files.

Why File Binders Are Used for Malware

Why are file binders used for malware exactly? They serve two purposes when used for malware. First, file binders make malware harder to detect. Antivirus software may overlook malware if it’s joined with a legitimate file — and that’s exactly what a file binder does. File binders join multiple files together. To counter antivirus software, a hacker may merge a piece of malware with one or more legitimate files.

File binders are also used in polymorphic viruses. Polymorphic viruses are those that change or “morph” over time. Like all viruses, they can self-replicate. While regular viruses create exact copies of themselves, though, polymorphic viruses create modified versions of themselves. File binders can be used for polymorphic viruses. A file binder may allow a virus to join with one or more files when self-replacing.

In Conclusion

File binders are utility tools that are designed to join multiple together. While they are used for different purposes, hackers may use for malware. When joined with one or more other files, malware is harder to detect. Furthermore, file binders can be used to create polymorphic viruses. File binders can modifiy viruses during the self-replication process.
