Examining Malware Web Browser Injections

Posted on 2019-03-23 by aswanda

Banking malware and information stealing malware are some of the most popular threats in today's landscape. Many stealers will collect information and credentials from locally installed applications such as web browsers, email and instant messaging clients, and other common software. Banking trojans, on the other hand, go the extra mile to pilfer data and use what is called Web browser injections, more commonly called "web injects". Web injects are code within malware that can inject HTML and JavaScript directly into otherwise legitimate websites a victim visits. This has the effect of modifying rendered browser content to achieve any number of goals the malicious actor chooses, such as adding, removing, or modifying text, inserting form fields, or capturing data entered into fields.
