Credential Harvesting
A comprehensive overview of Credential Harvesting in the context of email security.
Detailed Definition
Credential harvesting is the process of secretly gathering valid usernames, passwords, private keys, and email addresses. This is typically done through spoofed login pages, buying databases of breached credentials on the dark web, or using keyloggers.
Why It Matters
Knowledge of Credential Harvesting is vital. Ensuring proper configuration and awareness surrounding Credential Harvesting drastically reduces an organization's susceptibility to targeted attacks.
Real-World Examples of Credential Harvesting
Attackers send a mass email that looks like an Office 365 password expiration notice. Clicking the link takes users to a pixel-perfect replica of the Microsoft login page. Any username and password entered is saved by the attacker for later use in account takeover.
1. Case Study: Credential Harvesting Initial Access
In an observed attack pattern, an adversary utilizes Credential Harvesting to compromise an organization's initial perimeter. The threat actors are then able to maneuver laterally and escalate their privileges across the victim's infrastructure.
2. The Role of Credential Harvesting in Zero-Trust Defense
Organizations actively defend against this by integrating their Credential Harvesting policy with continuous monitoring and strict identity verification processes, removing default-allow actions entirely.
Credential Harvesting Flow
Lure
Attackers send out phishing emails claiming an account needs urgent verification.
Redirection
The user clicks the link and is taken to a malicious, convincing login page.
Input
The victim unknowingly enters their real credentials into the fake form.
Capture
The attacker's server stores the entered credentials in plain text.
Exploitation
Attackers immediately log into the real service using the harvested credentials.
Best Practices
- 1Regular auditing and continuous monitoring of Credential Harvesting implementations.
- 2Extensive employee training centered around identifying risks related to Credential Harvesting.
- 3Integration of Credential Harvesting into a broader Zero Trust security posture.
