Adobe reportedly tweaks your hosts file to detect Creative Cloud — and people aren’t happy

What happened

It has been reported that Adobe Creative Cloud installers add entries to users' hosts files on Windows and macOS to check whether Creative Cloud is already installed when someone visits adobe.com/home. The site attempts to load an image (https://detect-ccd.creativecloud.adobe.com/cc.png); if a hosts-file DNS entry points that hostname at an Adobe server the browser connects and Adobe concludes the app is present, otherwise the load fails. Allegedly, this is a fallback after Adobe’s earlier technique — pinging localhost on various ports — was thwarted when Chrome tightened Local Network Access restrictions.

Why it matters

The hosts file is a system-level configuration that most people never touch. Let a third-party scribble in there and you’ve crossed a line. Is this clever engineering or a privacy-and-trust violation? Plenty of commenters on OSNews and Hacker News compared it to old DRM-era transgressions — think Sony/BMG’s rootkit fiasco — and the tone is flat-out outraged. Editing hosts entries may not be a rootkit, but for many users it feels like the same kind of surprise tampering.

Adobe response and the fallout

As of reporting, Adobe had not publicly commented on these specific reports. Some users warn of worst-case scenarios — broken installs, system instability, or worse — while others shrug and call it a pragmatic workaround after browsers tightened local access. Who’s right? The emotional moment here is trust being chipped away: users don’t want their OS “helpfully” nudged by background telemetry tricks.

What you can do

If this bothers you, check your hosts file (Windows: C:\Windows\System32\drivers\etc\hosts; macOS: /etc/hosts) for unexpected Adobe entries and remove them if you’re comfortable doing so, or use endpoint tools that lock the hosts file. And ask loud questions: do you want commercial software rewriting your DNS rules? Because once the gates are opened, it’s hard to pretend we didn’t see it coming.
