Last week, the web hosting industry faced two severe "0-day" security threats: the cPanel authentication bypass and the Linux "Copy Fail" exploit. These were critical vulnerabilities that could have allowed unauthorized access to servers worldwide.
At Varial Hosting, we believe waiting for a patch is waiting too long. 🛡️ We took immediate action to ensure our clients remained protected throughout both events.
Here is how we stayed ahead of the timeline:
1️⃣ Immediate Mitigation: As soon as the cPanel flaw was identified, we "closed the door" by restricting access to vulnerable services—securing our servers before an official software patch was even finalized.
2️⃣ Kernel-Level Hardening: While the industry waited for OS vendors to release a fix for the "Copy Fail" threat, we implemented deep-system protections and performed controlled reboots to ensure 100% data protection.
3️⃣ Rapid Deployment: When official patches were released, we tested and deployed them immediately—finishing the work hours before standard maintenance windows even opened.
The result? For our clients, these global threats remained a non-event. No action was required on your part, and no data was at risk. We manage the complexity of server security so you don’t have to.
