Auditors generally publish their results in two places, their official website and their github.
They always update the github first and then the official site, so it can happen that an audit is legitimate but is not published on their site yet.
There have been cases of "rugpulls" where, through this delay, they have posted fake audits, uploaded to a fake github, and saying that the auditor simply hadn't updated the official site yet.
Always go to the auditor's official website first. If the audit is not published, look there for the official github to see if the audit is uploaded.
If it isn't, they are showing you a fake audit.
In our case you can check that the audit is official:
