When you download a file from the internet, Windows often adds a special “Mark of the Web” (MotW) attribute. This triggers security warnings when you try to open the file. However, attackers have found vulnerabilities in archiving software that can bypass this protection. When extracted, the files may not receive the MotW attribute, meaning Windows would not show a warning when you run a malicious executable hidden within the archive. This flaw allows malware to be executed as if it were a safe, local file.
Before extracting, use 7-Zip to "Test" the archive. This ensures the 18 GB download didn't corrupt during the transfer.
Once downloaded, you can extract the contents of the ZIP file using built-in tools on your computer (like Windows Explorer on Windows or Finder on macOS) or third-party software. Here's a basic process:

Safe and Responsible Downloading Practices
To help protect your digital infrastructure, could you share you are currently running and if this download has already been executed on your computer? Knowing whether your system is showing any sudden sluggish behavior or unusual network traffic can help me provide the exact remediation steps you need. Share public link
Another clever evasion technique involves manipulating the zip file's header information. Attackers can modify the header field. Antivirus engines rely on this metadata to know how to decompress a file. If the header is malformed, the antivirus may fail to decompress it entirely, leaving the payload un-scanned. A standard extraction tool like 7-Zip will also fail to decompress the file, but a custom loader, specifically designed by the attacker, can ignore the malformed header and decompress the malware directly. While this requires custom tooling to recover the payload, it effectively creates an invisible threat that can sit dormant on your system until activated.
Here’s why:
