# CVE-2021-44228 - Cyber Threat Intelligence
These _indicators_ were reported, collected, and generated during the [VulDB CTI analysis](https://vuldb.com/?kb.cti) of the campaign known as _CVE-2021-44228_. The _activity monitoring_ correlates data from social media, forums, chat rooms, and darknet markets. It helps to determine associated actors, specific activities, expected intentions, emerging research, and ongoing attacks. Our unique _predictive model_ uses _big data_ to forecast activities and their characteristics.
_Live data_ and more _analysis capabilities_ are available at [https://vuldb.com/?actor](https://vuldb.com/?actor)
