What happened
On 9 November 2026 Trustwave SpiderLabs posted on X that its MailMarshal service detected an active hiring-themed phishing campaign impersonating the background-screening company HireRight. According to the post, the email links to an attacker-created Calendly routing form with a fake document-review button such as View Document or View Proposal. Clicking it returns a link to a ScreenConnect MSI installer from an attacker-controlled ScreenConnect instance at treffert.screenconnect.com. HireRight, Calendly and ConnectWise ScreenConnect are legitimate companies whose brands or services were abused; they are not involved in the scam.
How the scam works
SpiderLabs' graphic shows the flow: a fake HireRight employment-reference email, a Calendly page asking the visitor to download a reference verification file, and then a ScreenConnect ClientSetup.msi download. Running that installer gives the attacker remote access to the computer. Example abused Calendly form paths listed in the post include calendly.com/d/dt89-7hh-5ww, calendly.com/d/dvcz-23t-bf6 and calendly.com/d/d4jf-gpc-ddy.
Hiring and background-check themes work because people expect to open documents for a job or reference check. Using a real Calendly address makes the middle step look routine, and ScreenConnect is genuine remote-support software that IT teams also use, so Windows may not block the installer as unknown malware.
Do not install remote-access software from an unexpected hiring or reference email. Anyone who ran the MSI should disconnect the computer, uninstall ScreenConnect if they did not install it themselves, change passwords from a clean device and have the machine scanned. Report the email to HireRight and to your security team if it reached a work inbox. The details come from the SpiderLabs post and have not been independently checked by scammers.com.
