# ProxyShell/ProxyLogon - 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 _ProxyShell/ProxyLogon_. 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)

## Countries

These _countries_ are directly (e.g. origin of attacks) or indirectly (e.g. access by proxy) associated with ProxyShell/ProxyLogon:

## TTP - Tactics, Techniques, Procedures

_Tactics, techniques, and procedures_ (TTP) summarize the suspected MITRE ATT&CK techniques used within ProxyShell/ProxyLogon. This data is unique as it uses our predictive model for actor profiling.

ID | Technique | Weakness | Description | Confidence
-- | --------- | -------- | ----------- | ----------
1 | T1068 | CWE-269 | J2EE Misconfiguration: Weak Access Permissions for EJB Methods | High
2 | T1592 | CWE-200 | Configuration | High

## IOA - Indicator of Attack

These _indicators of attack_ (IOA) list the potential fragments used for technical activities like reconnaissance, exploitation, privilege escalation, and exfiltration during ProxyShell/ProxyLogon. This data is unique as it uses our predictive model for actor profiling.

ID | Type | Indicator | Confidence
-- | ---- | --------- | ----------
