Below is an article covering why you should avoid these files and how to handle them safely.

If you’ve come across a download for a "Loader" or "Setup" file inside a .rar archive with the password 123 , you are likely being targeted by a cyberattack. While this setup might seem like a simple way to share software, it is a classic tactic used to deliver dangerous malware while evading your computer's built-in defenses. Why Do Hackers Use a Password?

Many of these loaders target cryptocurrency enthusiasts to drain digital wallets.

It isn't for your privacy. Encrypting a file with a password like "123" or "pass123" prevents many automated security tools and antivirus programs from scanning the contents of the archive. By the time you extract the file using the provided password, the malware is ready to run on your system. What’s Really Inside the Archive?

These files are often distributed through YouTube descriptions or forums as "cracks" or "activators" for expensive software.

Downloading a "Loader" file contained in a RAR archive with a simple password like "123" is a major security risk. Such files are frequently used by cybercriminals to bypass antivirus scans and infect systems with "stealer" malware designed to grab your passwords, crypto-wallet credentials, and personal data.

Any file that requires a simple, publicly provided password like 123 , 1234 , or password is highly suspicious.
