WBS 2018 Comparative Report: Protection Against Phishing

AUTHORS:

Morgan Dhanraj, Luis Rojo

TECHNOLOGY DESCRIPTION:

Phishing attacks gain the trust of users by masquerading as reputable entities to steal login credentials or sensitive account information. Examples of common phishing attacks include an email designed to look like the sender is a credible organization or a disguise that looks like it comes from someone familiar and trusted inside a company such as the IT department.

To protect against malware, leading browser vendors provide cloud-based reputation services, which scour the Internet for malicious websites and then categorize content accordingly, either by adding it to blacklists or whitelists, or by assigning it a score. A web browser requests reputation information about a specific URL, and if results indicate that the website is “bad,” the browser redirects the user to a warning message explaining that the URL is malicious. If a website is determined to be “good,” the browser takes no action and the user remains unaware that a security check was just performed.

To evaluate a browser’s effectiveness in protecting against phishing attacks, NSS’ testing focused on block rates, consistency of protection, and early protection against new threats.
