Watering Hole Attacks - CompTIA Security+ SY0-701 - 2.2
Understanding Watering Hole Attacks
Introduction to Network Security Threats
- The discussion begins with the concept of gaining unauthorized access to a network through social engineering tactics, such as leaving USB keys in public areas.
- It highlights the effectiveness of employee training in preventing phishing attempts via email links and attachments.
What is a Watering Hole Attack?
- A watering hole attack involves an attacker compromising a third-party website that employees frequently visit, waiting for them to access it.
- Example: Employees might order from local shops online; if attackers exploit these sites, they can infect the company’s network.
Mechanism of Attack
- Attackers may send malicious email attachments to third-party sites (like sandwich shops), hoping those sites will inadvertently compromise their security.
- The attacker specifically targets organizations by poisoning only certain sections of a website, focusing on IP addresses associated with particular companies.
Case Study: Real-world Application
- In January 2017, attackers successfully poisoned websites related to financial authorities in Poland and Mexico, targeting specific banks.
- Malicious JavaScript was added selectively for certain IP addresses while other visitors saw no signs of compromise.
Defense Strategies Against Watering Hole Attacks
- There is no single solution; layered defense strategies (defense in depth) are essential for protection against such attacks.
- Multiple security measures like antivirus software, firewalls, and intrusion prevention systems work together to identify and block threats effectively.
