OysterLoader is a loader family that researchers tracked throughout 2024 in distribution campaigns that used malicious Chrome browser extensions and malvertising. It maintains persistence on Windows systems and delivers heavier payloads such as information stealers, and its operators refresh the code regularly to defeat detection.
