In Security

Pass-the-Hash (PtH) attacks are a serious threat to organizations, allowing cybercriminals to exploit hashed credentials to access systems and data unlawfully. To protect against PtH attacks, it’s essential to understand their mechanisms, implications, and preventive measures.

What is a Pass-the-Hash Attack?
A Pass-the-Hash attack bypasses traditional authentication by using hashed credentials rather than cracking passwords. Attackers capture a password hash and use it to authenticate as the legitimate user, without needing the actual password.
How Pass-the-Hash Attacks Work
  1. Hashing: Converts a password into a fixed-length hash, which is stored in the system. During login, the system hashes the entered password and compares it to the stored hash.
  2. Kerberos and NTLM Protocols: In Windows environments, NTLM is particularly vulnerable. Attackers who obtain an NTLM hash can use it to authenticate to other systems without knowing the plaintext password.

Attack Steps

  1. Initial Compromise: Gain system access via phishing, exploiting vulnerabilities, or stolen credentials.
  2. Hash Extraction: Extract password hashes from memory or security databases.
  3. Lateral Movement: Use hashed credentials to authenticate to other network systems, expanding access.
