Maybe the crime of the century if you ask me. Just like in ‘Hackers’ and ‘Office Space’ a California man has been indicted for a inventive scheme that allegedly siphoned $50,000 from online brokerage houses E-trade and Schwab.com in six months — a few pennies at a time, and using the names of cartoon characters.
A salami attack is a series of minor data-security attacks that together results in a larger attack. For example, a fraud activity in a bank where an employee steals a small amount of funds from several accounts, can be considered a salami attack.
The main idea is to make the change as minuscule as possible so that any single transaction will go completely unnoticed[1] (This is due in part to round-off and truncation error[2]).
