Predictable serial number attack
open-in-new
<p>A predictable serial number attack is a form of <a href="/facts/Security_exploit/EdlqsRJM">security exploit</a> in which the <a href="/facts/Algorithm/fnl5NmRt">algorithm</a> for generating <a href="/facts/Serial_number/2XUENAvJ">serial numbers</a> for a particular purpose is guessed, discovered, or <a href="/facts/Reverse_engineering/pmJCV7J7">reverse engineered</a>, a new serial number is predicted using the algorithm, and the newly generated serial number is then used for a <a href="/facts/Fraud/VyU68aBy">fraudulent</a> purpose, either to obtain an undeserved benefit or to deny service to the legitimate holder of the serial number. </p>
