5 Real Vulnerabilities We Find Most Often in SMB Networks
Published by Synactive Security Team · 4 min read
Small and medium-sized businesses are increasingly targeted by attackers—not because they're easy, but because they're often under-resourced.
Here are five issues we encounter repeatedly during security assessments.
1. Exposed Remote Desktop (RDP)
Systems exposed directly to the internet remain a common ransomware entry point.
Recommendation: Restrict RDP access using VPNs, MFA, or secure gateways.
2. Weak Password Policies
Shared passwords, predictable credentials, and lack of MFA remain widespread.
Recommendation: Enforce strong passwords and enable MFA across all critical systems.
3. Outdated Software
Legacy applications frequently contain publicly known vulnerabilities.
Recommendation: Maintain a structured patch management process.
4. Excessive User Privileges
Users often have local administrator rights they don't need.
Recommendation: Apply the principle of least privilege.
5. Misconfigured Cloud Storage
Improperly configured cloud buckets and file-sharing permissions can expose sensitive data.
Recommendation: Regularly audit cloud permissions and access controls.
Conclusion
None of these vulnerabilities are particularly advanced.
Yet together, they account for a significant portion of successful attacks against SMBs.
Addressing them can dramatically improve an organization's security posture.
