Cyber Research Unit (CRU)

Threat Hunting and Threat Intelligence for TSPs and MSPs

Meet the team dedicated to decoding the mysteries of cybersecurity

All about the CRU

Security Content

All the latest in security news. The CRU identifies new vulnerabilities, researches them, and shares what they find with all to see.


The CRU has developed automated tools to perform basic analysis on security incidents to help automatically make decisions on escalation and remediation. 


With “research” in the name, it only makes sense that research is involved. They dig deep into automated and manual malware analysis, vulnerabilities, and more.


The CRU monitors ransom leak sites and malicious botnets for new threats, uses OSINT resources, and utilizes data from the Perch platform to help create content and complete research.

Threat Hunting

With the CRU, cyber threat hunting involves building visualizations to highlight abnormal activity, searching through data for new indicators of compromise (IoCs), or testing various queries and reviewing the results.


The CRU is a big fan of hosting CTFs, and for good reason. From their eyes, cybersecurity capture the flag events are a great way to dip your toes into cybersecurity or build upon expert skills.

Initial Access Brokers
Successful cybercrime attacks often take groups of individuals working together. Some are extremely organized cybercrime syndicates such as the Conti group, but often individual criminals provide services to other criminals as vendors operating through a marketplace. Ransomware-as-a-Service (RaaS) or Botnet-as-a-Service (BaaS) providers regularly advertise their services on forums such as Exploit or XSS and setup affiliate programs. One type of service that can be found within the cybercrime ecosystem is the initial access broker (IAB).

ConnectWise Cyber Research Unit Threat Feeds

This repository contains lists of threat intelligence discovered by the CRU using our internal sandbox built on top of the Perch platform or found while threat hunting. This data is threat intelligence the CRU has been collecting for years and using internally at ConnectWise for threat hunting and threat analysis assistance. We use this intelligence daily, searching for these indicators in our customer's network data to find new threats and filter out false positives. This feed is updated daily.
