Question
Windows LAN Manager (LM) hashes are known to be weak. Which of the following are known weaknesses of LM? (Choose three.)
Options
- AConverts passwords to uppercase.
- BHashes are sent in clear text over the network.
- CMakes use of only 32-bit encryption.
- DEffective length is 7 characters.
Explanation
This question identifies known cryptographic weaknesses associated with the deprecated Windows LAN Manager (LM) hashing algorithm.
Common mistakes.
- C. LM hashes internally use a variant of the DES (Data Encryption Standard) algorithm, which is a 56-bit key algorithm, not 32-bit encryption; the statement is technically incorrect regarding the underlying cryptographic strength.
