While the RAR format itself is safe, it is a common way for attackers to hide malware or viruses.

If you did not expect to receive a file named "54614.rar" or if it came from an untrustworthy source, do not open it. Attackers often use social engineering to trick users into opening malicious archives.

Simply extracting the files is generally safe; the danger occurs if you run an executable file (like an .exe or .bat ) that was hidden inside the archive.

Always use an antivirus program like Microsoft Defender to scan the archive before extracting it.
