Threats - WAF limitations

One of the biggest trends in securing the web against skimming is to use a web application firewall (WAF).

What is WAF?

Web application firewall is a special type of application firewall that applies specifically to web applications. It is deployed in front of web applications and analyzes bi-directional web-based (HTTP) traffic - detecting and blocking anything malicious

How WAF can let you down?

WAF is an OSI layer 7 defense mechanism against attacks known as application-layer attacks, and it protects services that user-facing web applications use to present data. WAF is not protecting browser-level user interface itself. If a web application and its user experience is a house, then WAF protects walls, not the furniture or electronics inside.

Drive-by skimming

Steals data of hundreds of websites in one hit

Sideloading

WAF does not protect against skimming performed by a sideloaded JavaScript code.

Third-arty JavaScript code

Attackers load skimming code on target web pages using legitimate scripts and tools

Multi-stage attacks

Skimming code uses anti-forensics or loads only on target web pages

Supply chain attacks

It's often a lot easier to add skimming code to a third-party JavaScript code because it's not part of internal security oversight. Additionally, attacking third-party tools allows hackers to penetrate almost all the customers of the target third-party. This type of attack is commonly called "drive-by skimming."
