What is salami attacks?

Answer 1

Salami attack

In the salami technique, cyber criminals steal money or resources a bit at a time. The 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 cyber criminal will make a sizable amount of money every month.

The classic story about a salami attack is the old " collect-the-roundoff " trick. In this scam, a programmer modifies arithmetic routines, such as interest computations. Typically, the calculations are carried out to several decimal places beyond the customary two or three kept for financial records. For example, when currency is in dollars, the round off goes up to the nearest penny about half the time and down the rest of the time. If a programmer arranges to collect these fractions of pennies in a separate account, a sizable fund can grow with no warning to the financial institution.

To quote an example, an employee of a bank in USA was dismissed from his job. Disgruntled at having been supposedly mistreated by his employers the man first introduced a logic bomb into the bank's systems.

Logic bombs are programmers, which are activated on the occurrence of a particular predefined event. The logic bomb was programmed to take ten cents from all the accounts in the bank and put them into the account of the person whose name was alphabetically the last in the bank's rosters. Then he went and opened an account in the name of Ziegler. The amount being withdrawn from each of the accounts in the bank was so insignificant that neither any of the account holders nor the bank officials noticed the fault.

It was brought to their notice when a person by the name of Zygler opened his account in that bank. He was surprised to find a sizable amount of money being transferred into his account every Saturday.

Answer 2

A salami technique is an automated form of abuse involving Trojan horses or secret execution of an unauthorized program that causes the unnoticed or immaterial debiting of small amounts of assets from a large number of sources or accounts. The name of this technique comes from the fact that small slices of assets are taken without noticeably reducing the whole. Other methods must be used to remove the acquired assets from the system.

For example, in a banking system, the demand deposit accounting system of programs for checking accounts could be changed (using the Trojan horse method) to randomly reduce each of a few hundred accounts by 10 cents or 15 cents by transferring the money to a favored account, where it can be withdrawn through authorized methods. No controls are violated because the money is not removed from the system of accounts. Instead, small fractions of the funds are merely rearranged, which the affected customers rarely notice. Many variations are possible. The assets may be an inventory of products or services as well as money. Few cases have been reported.
