Question 1

How do I use mimic to prank someone with a JavaScript file?

Accepted Answer

Pipe the JavaScript file through mimic in the terminal, e.g., `cat script.js | mimic > fake.js`. This substitutes ASCII characters with homoglyphs, making the code look correct but fail to run, as shown in the README examples.

Question 2

What are some common homoglyphs that mimic uses?

Accepted Answer

Mimic replaces characters like semicolons with Greek question marks or ASCII letters with similar Unicode variants. The README highlights the semicolon substitution inspired by a tweet, causing syntax errors in C# code.

Question 3

How can I detect if my code has been tampered with by mimic?

Accepted Answer

Use text editors with Unicode inspection modes or linters that flag non-ASCII characters. Writing scripts to check for homoglyph patterns can also help identify substitutions, as mimic doesn't provide detection tools.

Question 4

Is mimic similar to other obfuscation tools like UglifyJS?

Accepted Answer

No, while tools like UglifyJS minify code for performance, mimic focuses on visual deception with homoglyphs for pranks. It doesn't optimize or secure code but creates syntactical errors, as described in its philosophy.

Question 5

Can mimic be reversed to restore the original code?

Accepted Answer

Mimic doesn't include a reversal feature, so fixing requires manually replacing homoglyphs with correct ASCII characters. Creating a mapping table based on common substitutions is necessary, which adds overhead.

Question 6

Why would anyone use mimic beyond pranks?

Accepted Answer

It's primarily for educational purposes to demonstrate Unicode vulnerabilities or for code review challenges. The README mentions using it to spark curiosity and discussions on character encoding issues.
