Micro-Learning Topic: Information disclosure (Detected by phrase)

Matched on "Information Exposure"

Many web applications and APIs do not properly protect sensitive data, such as financial, healthcare, and PII. Attackers may steal or modify such weakly protected data to conduct credit card fraud, identity theft, or other crimes. Sensitive data may be compromised without extra protection, such as encryption at rest or in transit, and requires special precautions when exchanged with the browser.

Micro-Learning Topic: Integer overflow (Detected by phrase)

Matched on "Integer Overflow"

What is this? (2min video)

Integer overflow occurs when the result of arithmetic operation is greater than the maximum value the integer data type can store.
For example, if an integer data type allows integers up to two bytes or 16 bits in length (or an unsigned number up to decimal 65,535), and two integers are to be added together that will exceed the value of 65,535, the result will be integer overflow.
