Note : This is referance only to CWM.zip , which is temporary/touch recovery commonly used to root device. Other cwm recoveries which are permanent and getting along with custom kernels are safe.
Entropy have quoted this
After seeing multiple reports of Superbricks connected with a "cwm.zip" - I've finally found the source of that file - here.
I checked the recovery binary using "strings" to see if it was a "dangerous" or "safe" one.

DON'T USE CWM.zip (touch recovery) at all
