Beware fake campus emergency alerts
Caltech and other universities have been receiving phish that claim to come from Campus Security about a situation on campus. They contain a link that will either take you to a fake login page or to a page infected with malware. Since any link in a real Caltech Alert email is optional we recommend never clicking on any link in such an email.
For more information on Caltech Alert and how to download the mobile app, please see https://www.emergencypreparedness.caltech.edu/Communications. Note that messages on the smartphone app cannot be faked by phishers.
