It looks like you’re asking for an article based on a search term that includes a suspicious placeholder (--39-LINK--39-), which often appears on spam sites, forum auto-generated posts, or link-shortening farms.
Instead of simply repeating that keyword phrase, I’ve written a legitimate, helpful, and security-focused article explaining why you might see such strings, how to safely obtain macOS Catalina 10.15.7 if you truly need it, and why you should avoid clicking on suspicious “ISO download” links.
Once you have the official .app installer, convert it to a bootable ISO yourself:
hdiutil create -o /tmp/Catalina -size 8500m -volname Catalina -layout SPUD -fs HFS+J
hdiutil attach /tmp/Catalina.dmg -noverify -mountpoint /Volumes/Catalina
sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Catalina --nointeraction
hdiutil detach /Volumes/Catalina
hdiutil convert /tmp/Catalina.dmg -format UDTO -o ~/Desktop/Catalina.cdr
mv ~/Desktop/Catalina.cdr ~/Desktop/Catalina.iso
That yields a clean, malware-free ISO for use in virtualization (UTM, VirtualBox, VMware).
