After i pass exam on last year ooh my god "
congratulation you pass this exam"
But after i sent my endorsement to isc2, they reply this email to me
"As part of our ongoing  forensic analysis of examination data, we carefully reviewed your  examination responses.  This review revealed a number of irregularities  in your examination responses.  Based on forensic analysis, and further  investigation, we have concluded that your exam score cannot be  certified as representing a valid measure of a candidate’s competence in  the domains assessed by (ISC)2.  (ISC)2 has therefore invalidated your  CISSP certification examination results.
Pursuant to the (ISC)2 Examination Agreement which you accepted prior to  the exam, this letter is serving as notice that your exam score has  been voided and you are prohibited from sitting for any (ISC)² exam for a  period of one (1) year.
(ISC)2 does not take this action lightly.  To validate the legitimacy of  exam scores, and confirm a candidate’s knowledge and experience in the  field of information security, (ISC)2 conducts this analysis as part of  its examination security program.  As the leading credential for  information security professionals worldwide, and because of the  significance placed on achieving an (ISC)2 credential, it is important  to safeguard the validity and protect the security of the (ISC)2 exam."
And they can't explain why?
