PYSA - Cyber Threat Intelligence
These indicators were reported, collected, and generated during the VulDB CTI analysis of the actor known as PYSA. 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.pysa
Countries
These countries are directly (e.g. origin of attacks) or indirectly (e.g. access by proxy) associated with PYSA:
IOC - Indicator of Compromise
These indicators of compromise (IOC) indicate associated network resources which are known to be part of research and attack activities of PYSA.
| ID | IP address | Hostname | Campaign | Confidence |
|---|---|---|---|---|
| 1 | 23.129.64.190 | - | - | High |
| 2 | 45.147.231.210 | - | - | High |
| 3 | 185.220.100.240 | tor-exit-13.zbau.f3netze.de | - | High |

There are 9 more IOC items available. Please use our online service to access the data.
TTP - Tactics, Techniques, Procedures
Tactics, techniques, and procedures (TTP) summarize the suspected MITRE ATT&CK techniques used by PYSA. This data is unique as it uses our predictive model for actor profiling.
| ID | Technique | Weakness | Description | Confidence |
|---|---|---|---|---|
| 1 | T1006 | CWE-22, CWE-29, CWE-35 | Pathname Traversal | High |
| 2 | T1040 | CWE-319 | Authentication Bypass by Capture-replay | High |

There are 22 more TTP items available. Please use our online service to access the data.
IOA - Indicator of Attack
These indicators of attack (IOA) list the potential fragments used for technical activities like reconnaissance, exploitation, privilege escalation, and exfiltration by PYSA. This data is unique as it uses our predictive model for actor profiling.
