TrustCor and Untrustworthy Certificate Authorities

Untrustworthy certificate authorities like TrustCor can pose a serious threat to online security. TrustCor, a certificate authority that operated during the early 2010s, was responsible for issuing fraudulent digital certificates. These certificates are used to verify the identity of websites and establish secure connections between users and those websites. TrustCor was able to issue fraudulent certificates because it was part of a network of trusted certificate authorities. These organizations are trusted by web browsers and operating systems to issue digital certificates, so when TrustCor issued a fraudulent certificate, it was automatically trusted by most users’ devices.
