10. 4.SALAMI ATTACKS Used for the commission of financial crimes.
Key here is to make the alteration so insignificant that in a single case it would go completely unnoticed.
E.g. a bank employee inserts a program, into the bank's servers, that deducts a small amount of money (say Rs. 5 a month) from the account of every customer. No account holder will probably notice this unauthorized debit, but the bank employee will make a sizable amount of money every month.
