Received a letter from LexisNexis notifying me that my id was stolen [from Seisint -a private database intended for tracking terrorists]

and that I should sign up for a free years subscription to a credit monitoring service called Triple Advantage at ConsumerInfo.org. , an Experian company.
Anyone else get a letter like this ?
I checked with the FTC and the Credit Bureau and Experion seems legit though ConsumerInfo is only licensed by them .
