# Hardcoded iv

<AccordionGroup>
  <Accordion title="hardcoded-iv">
    Initialization Vectors (IVs) for block ciphers should be randomly generated each time they are used. Using a static IV means the same plaintext encrypts to the same ciphertext every time, weakening the strength of the encryption.<br />**Likelihood**: MEDIUM<br />**Confidence**: HIGH<br />**CWE**: <br />- CWE-329: Not using a random initialization Vector (IV) with Cipher Block Chaining (CBC) Mode causes algorithms to be susceptible to dictionary attacks.
