ConnectWise’s ScreenConnect screen sharing utility is widely used by Managed Security Providers (MSPs). Their Cyber Research Unit (CRU) publishes an annual MSP Threat Report, highlighting critical cybersecurity trends affecting MSPs and MSSPs. The report covers:
– Ransomware trends
– Vulnerabilities in MSP tools
– EDR evasion techniques
– Drive-by Compromises

You Should Know:
1. Ransomware Defense (Linux & Windows)
- Detect suspicious processes (Linux):
ps aux | grep -E '(crypt|ransom|encrypt)'
- Block ransomware extensions (Windows):
Get-ChildItem -Path "C:\" -Recurse -Include .locked,.encrypted | Remove-Item -Force
2. EDR Evasion Techniques
Attackers bypass EDR by:
- Process hollowing
- Reflective DLL injection
- Living-off-the-land binaries (LOLBins)
Detect malicious PowerShell:
Get-WinEvent -LogName "Microsoft-Windows-PowerShell/Operational" | Where-Object { $_.Message -like "Invoke-Expression" }
3. Drive-by Compromise Prevention
- Block malicious domains via hosts file (Linux/Windows):
echo "0.0.0.0 malicious.com" | sudo tee -a /etc/hosts
- Scan for browser hijacks (Linux):
grep -r "extension_id" ~/.config/google-chrome/Default/Extensions
What Undercode Say:
MSPs must move beyond compliance checklists and adopt threat intelligence-driven security. Key takeaways:
– Patch management automation is critical.
– EDR misconfigurations lead to breaches.
– Ransomware gangs increasingly target MSPs.
Additional Commands for MSP Security:
- Check open ports (Linux):
sudo netstat -tulnp
- Audit Windows logs for brute force attacks:
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625} - Scan for vulnerable services (Nmap):
nmap -sV --script vuln <target_IP>
Expected Output:
- Actionable threat intelligence from ConnectWise CRU.
- Hardened EDR policies to prevent evasion.
- Proactive ransomware detection via log analysis.
Prediction:
MSPs that ignore threat intelligence will face more supply-chain attacks in 2024-2025. Automation and behavioral detection will become mandatory.
