This spam was delivered by the NACHA, which is a non profit organization in U.S which looks after the systems of the ACH i.e. automated clearing house.

ACH has being used greatly but the aging systems which are used by the financial institutes. These institutions use those systems for the purpose of exchanging any of the details related to checks, direct deposits or any sort of cash transfer done by individuals or businesses too. In the year 2004, ACH was used in almost 9 billion of the transactions who were valued to be more than US$ 24.4 trillion.

During the previous some months, much of the companies have lost their money by this ACH fraud. This loss of money was basically done at the point when the fraudsters got the authentication credentials as needed to transfer the money. It has been observed in most of the cases that the major portion of the money which was taken through the fraudulent transfer was not recovered and that has left the businesses to be hooked with their banks.
