Addtional CCleaner 5.33.6162 -- unanswered question

Can you clarify why there is a second build of "5.33.6162" signed 16 minutes later? Why was this second copy created? What is changed? Is it typical to build and sign a second copy of the software (and installer) ever? (or not to change the build number?)

Is the malware different in version B? Does it connect to another server?

I'm open to non-staff input and speculation. Which ones did you encounter?

Hi NonConvergentWaveform,

From time to time we build a second set of binaries for testing purposes. A test version was built for version 5.33.6162 and this build was also affected by the compromise.

Thank you for your valid and concise answer.
