What to do
AI-suggested
To mitigate this threat, European organizations should: 1) Immediately verify if their Roundcube installations are running version 1.6.10 and assess exposure of the webmail interface to the internet. 3) Restrict access to the Roundcube web interface using network-level controls such as VPNs, IP whitelisting, or web application firewalls (WAFs) with specific rules to detect and block exploit attempts. 4) Monitor server logs and network traffic for suspicious activities indicative of exploitation attempts, including unusual Perl script executions or unexpected outbound connections. 5) Implement strict input validation and sanitization if custom modifications exist. 6) Conduct regular security assessments and penetration testing focused on webmail infrastructure. 7) Educate IT staff about the risks and signs of exploitation to enable rapid incident response. 8) Consider isolating the Roundcube server in a segmented network zone to limit lateral movement in case of compromise.
