1. What is being reported?
The report highlights that attackers are using weaknesses in email systems (SMTP), VPNs, firewalls, and routers to gain remote access and control over these devices. This type of attack is known as remote code execution (RCE), meaning hackers can run harmful commands on your systems without permission.
2. What this means in plain English
If an attacker successfully exploits these vulnerabilities, they could access sensitive information, disrupt your internet connection, or use your network to launch further attacks. This risk is serious because these devices often serve as the first line of defence for your business network.
3. Could this affect a small business?
Small businesses using common email servers, VPNs, firewalls, or routers could be affected, especially if these devices are not regularly updated or properly secured. Organisations without dedicated IT security teams should be particularly cautious.
4. What to do now
- Check with your IT provider or software supplier to ensure all your email servers, VPNs, firewalls, and routers have the latest security updates installed.
- Review and strengthen your network device passwords and access controls to prevent unauthorised entry.
- Monitor your network for unusual activity that could indicate an attempted or successful attack.
- Ensure your backup procedures are up to date so you can recover quickly if an incident occurs.
5. Ask your IT provider
Can you confirm that all our email servers, VPNs, firewalls, and routers are patched against the latest remote code execution vulnerabilities reported recently?
6. Bottom line
Keep your network devices updated and secure to prevent attackers from exploiting these new threats.
