A watering hole attack compromises or imitates a website that a target group is likely to visit so the attacker can infect, monitor, or exploit those visitors. It matters because attackers sometimes target trusted habits and routines rather than attacking victims directly first.
What is a Watering Hole Attack?
In a watering hole attack, the adversary identifies websites, forums, portals, or online resources that a target population regularly uses, then compromises or spoofs them to deliver malicious content or harvest information. This method is often associated with targeted campaigns and patient adversaries.
Because the lure is a site the victims already trust or normally use, watering hole attacks can be harder for users to detect than generic phishing attempts.
How Watering Hole Attacks Commonly Work
Common patterns include compromising a legitimate site, injecting malicious scripts, redirecting users, fingerprinting visitors, serving exploit content selectively, or harvesting credentials from a cloned trusted page.
Watering Hole Attack vs. Phishing
Phishing usually pushes a lure directly to the victim. A watering hole attack waits at a location the victim is likely to visit naturally and then attacks there.
