Is there a version limit on this? I just get an error when I try to import:

Loading configuration... /tmp/upload_template.tmpl 01070712:3: Caught configuration exception (0), ERROR app_template - /Common/WannaCry_Blocker_v2 definition: line 3 [undefined procedure: iapp::template][iapp::template start] line 75 [undefined procedure: iapp::conf][iapp::conf "create ltm rule WannaCry-Blocker { ${patched} }"] - sys/validation/AppTemplateAction.cpp, line 127. Unexpected Error: Loading configuration process failed.

The iApp should run on version 11.4+ I think. The iRule inside it should work on version 11.0+. What version is your BIG-IP running?

Of course, its running 11.3.0
