 ## Overview of the Vulnerability
 
-Cryptographic algorithms use an initial block of data (called an initialization vector) alongside the plaintext data that is encrypted. When this IV is reused for multiple encryptions, an attacker can identify the IV from the original data within the encryption.
+Cryptographic algorithms use an initial block of data called an Initialization Vector (IV) alongside the plaintext data that is encrypted. When this IV is reused across multiple encryptions, the cryptographic algorithms are weakened as an attacker can differentiate the IV from the original encrypted data. This can lead to further targeted attacks.
