The CRDF Threat Center is a service published by the independent French laboratory CRDF Labs. This service detects malicious URLs that violate our detection criteria and integrates these URLs into our databases to combat cybercrime.
CRDF Labs develops its own detection systems, sharing with others our threat intelligence data and technologies to fight and detect security risks. CRDF Labs is a nonprofit laboratory, independent and completely transparent to its users.
The CRDF Labs laboratory has its own R & D and its own detection and analysis tools. The CRDF Threat Center is a demonstration of our unique know-how in the detection of security risks on the Internet.
These technologies are based on our old Blockulicious, Blockulicious DNS and CRDF Sandbox products.
We do not want anyone to be infected with this homepage accessible to everyone. We prefer someone interested in our databases to come forward and contact us to discuss possible access to CRDF Threat Center's private area.

CRDF Labs is not intended to provide any evidence that a website is against our detection criteria. The purpose of CRDF Labs is to protect its users against security risks associated with a browser over the Internet.
If our system tells you that the URL is not contained in our database, your website is not contained in our database and your website is not blacklisted. No need to contact us to ask for information, we would have nothing more to communicate to you.
This is perfectly normal. The propagation can take several hours to get synchronized with VirusTotal. It is not necessary to contact us to report this error. Everything is automatic and the process will automatically delete the detection on VirusTotal at the next occurrence.
If you still have it after hours, consider refreshing the report when scanning a VirusTotal URL.

If you send us an email without using this procedure, we will not reply as indicated on our pages.
