Threat Hunting and Threat Intelligence for TSPs and MSPs

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.

Automation

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

Research

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.

Intelligence

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.

CTFs

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.

The initial sighting showed an Emotet DLL being downloaded by Trickbot, but since then multiple reports have come in of new malicious emails with malicious Emotet attachments spoofing replies from stolen email chains, presumably originating from already infected hosts.
