# APT33 - Cyber Threat Intelligence These _indicators_ were reported, collected, and generated during the [VulDB CTI analysis](https://vuldb.com/?kb.cti) of the actor known as [APT33](https://vuldb.com/?actor.apt33). 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.apt33](https://vuldb.com/?actor.apt33) ## Campaigns The following _campaigns_ are known and can be associated with APT33: * Elfin * PoshC2 * Powerton ## Countries These _countries_ are directly (e.g. origin of attacks) or indirectly (e.g. access by proxy) associated with APT33: * [US](https://vuldb.com/?country.us) * [DE](https://vuldb.com/?country.de) * [PL](https://vuldb.com/?country.pl) * ... There are 10 more country items available.
