* **Step 3** – User information is sent to attackers.
#### Sideloading And Chain-loading of Code
#### Platform Or Cloud-Hosted Skimming
#### The Backdoors
Most organizations struggle with a single source of truth for their client-side code. Step one is actually knowing what exists. Let’s look into why most organizations struggle in discovering and classifying front-end assets. What more do we need to know?
**Complexity** in front end security leads to **mistakes**.
Mistakes, eventually, **lead to breaches**.
What does client-side chaos look like?

Top Four Vectors Of Client-side Web Skimming Attacks
1. Front end code, aka ‘the digital user experience’, can actively ingest customer/user information at the data input points including login and financial transaction forms, or any other web forms where organizations are processing sensitive user data.
* Are you aware of every backdoor?
* Do you know what is flowing through these backdoors?
* Can you lock and control backdoors?
The Client-side (Front End) Problem Is Twofold:
