"Email Configuration Error" Phishing Attack

A phishing attack urging users to download undelivered emails was reported to DoIT Security this week. Here is an example of the malicious message.

Date: 03 Sep 2020 14:40:40 +0800

Email account: (redacted)@umbc.edu

Time of error 9/3/2020 2:40:40 p.m.

If you do not retrieve your undelivered emails now, they may be lost forever.

umbc.edu Email Server

The link to “download” undelivered emails leads to a website which prompts users to enter their UMBC credentials, potentially giving malicious actors access to victims’ UMBC accounts.

Notice the warning signs in this email. First, check the sender address, and notice that the supposed "umbc.edu System Administrator" is not using a umbc.edu address. Next, check the time and time zone of the message. The time zone UTC+0800 is used in China and parts of Australia and Russia, for example, but not anywhere that a legitimate email about your UMBC account would likely originate. Finally, be wary of unexpected emails requiring immediate action. Malicious actors try to induce panic to make victims act before thinking about the risks.

If you do receive this or any other email that you suspect is a scam, please do not click on any URL or reply. Either of those actions confirms to the sender that your email address is valid. Please forward the message (with the email headers) to security@umbc.edu.
