Thanks for the comments, David. I initially thought the same, but according to the reference and the recent Drupal exploit traffic we are seeing, the detection should still be valid. However, I haven’t tested this. So my comments above are yet to be validated. I will definitely check the reference you pointed out. Thanks again.
