Analysis Summary

The organizations welcoming back workers are enacting testing programs and workplace rules to guard against COVID-19 infections. To prepare employees, many companies are offering webinars and training videos to explain the new rules and requirements. Of course, cybercriminals are aware of this trend and are actively exploiting it. The attackers are deploying emails and malicious files masquerading as COVID-19 training materials. One particular email tries to trap the recipient into signing up for a phony employee training seminar. Clicking the link in the email actually leads the person to a malicious website designed to capture their Microsoft credentials.
