Is malicious?

The domain has recently been flagged as compromised for many users, leading to some believing it to be malicious. However, is a legitimate domain that belongs to Let’s Encrypt, a non-profit certificate authority run by the Internet Security Research Group. According to Let’s Encrypt, the domain is used to host OCSP, CRLs, and issuer certificates.


Valkyrie Verdict, an online file verdict system that checks files to identify malicious ones, has classified the domain as malware but no anti-virus software or other similar service is detecting the same. A search of the domain with Google shows many results claiming that is dangerous and may even lead to a serious malware infection. However, that is not actually the case. Analysis reports indicate that it’s a clean domain, making the flagging a likely false positive. Let’s Encrypt itself has said they are aware that the domain has been flagged as compromised and are working to remediate the error. The false-positive detection should be fixed in the near future if it hasn’t already been done as it’s impacting many users. This should at least put users at ease that it’s not harmful and nothing to worry about. removal

Since being flagged as compromised is likely a false positive, there’s nothing that you need to do. Let’s Encrypt will have to fix the error on their end.
