Citrix receiver malware
This time around the chain of trust has been broken again, but the problem isn't the certificates, it's the CA that vouches for the certificates. A CA is an trusted organization that issues certificates. In the case of Mac apps, you're really supposed to get your certificates directly from Apple. However, not everyone does, and some companies will use certificates obtained from third parties to sign their apps. Citrix did exactly this, and the decision has come back to haunt them.
It turns out, they made a really poor choose of CA to obtain their certificate from: Symantec. A few years ago, Symantec offered CA services. An important part of being a certification authority is trust, and Symantec made some big mistakes as a CA. Those mistakes led to an investigation, and what was found was highly concerning.
As a result, it was widely agreed that trust for Symantec certificates should be gradually phased out. The slow process of distrusting Symantec certificates began in On August 23, , Apple pushed out an update for XProtect and other security systems that, among other things, rejects any code signed with certificates issued by Symantec. The Gatekeeper process in macOS will reject any apps signed with such a certificate, showing the infamous "will damage your computer" message.
For those technically inclined and in possession of one of the affected apps, you can verify this yourself with the codesign and spctl commands in the Terminal:.
The codesign command shows that the code signature is still valid—meaning that the app hasn't been tampered with and the certificate hasn't been revoked.
However, the spctl command, which checks the file with Gatekeeper, shows that it is rejected, and thus will not be allowed to run. The best fix is to simply remove or update the affected software. Unfortunately, we can't help you with that. We're good at removing malware here at Malwarebytes, but that's not what this is.
