I am writing to alert you to a number of recent – and, unfortunately, successful -- email phishing scams that have been received by faculty and staff at Carnegie Mellon or by other schools. These scams target Workday users, DropBox users, Blackboard users, and research faculty with the goal of capturing login ids and passwords for various purposes. They impersonate our official email addresses and service providers. The email messages and websites they lead to are sophisticated, look legitimate, and require due diligence in detecting and reporting.
See additional details for each of these scams below.
As April 1 approaches, a day notorious for pranks and scams, please be on increased alert for scams:
- Avoid clicking on links or opening attachments in unexpected email;
- Check in with senders to be sure a message is legitimate before taking action;
- Never send your username and password in response to an email, no matter how urgent sounding;
- Validate URLs or use known good URLs or bookmarks to navigate to university services;
- Question unexpected callers before providing requested information.
If you receive suspicious emails, phone calls or other forms of contact, please report as soon as possible to email@example.com.
The ISO will triage the situation and if necessary block campus access to malicious destinations, notify affected parties, and take other actions to contain harmful effects. The sooner you report, the sooner we can protect.
From the entire ISO team, thank you for remaining vigilant, reporting concerns, following procedures, and assisting in our response efforts. We appreciate your partnership in keep CMU’s data, systems, and networks secure.
Thank you,Mary Ann Blair
Director of Information Security
Carnegie Mellon University
Thursday night starting around 9:45 PM a phishing email attack was sent to CMU email addresses.
The phishing message was a fake Dropbox shared document notification pretending to be from "Farnam Jahanian via Dropbox [firstname.lastname@example.org]".
This phish asks users to click on a link leading to a fake Dropbox login page and provide their username and password. The fake login page showed logos for Gmail, AOL, Windows Live, Yahoo and "other emails" and prompted with the text "To view the shared document, you are required to Login with your email address below"
This is not a legitimate e-mail and it was not an ISO phish training campaign. ISO notified the recipients around 11:35 PM that same evening.

Identity Finder version 8.1 is now available and is compatible with Windows 7+ and Mac OS X 10.9+. Identity Finder is licensed by Carnegie Mellon University to protect sensitive information from Identity Theft. The University offers this software at no cost to faculty, staff and students.
Version 8.1 identifies and highlights sensitive data stored in documents, applications, email and browsers.
Carnegie Mellon University has over 13,200 students and 5000 faculty and staff. With so many employees and students, it is likely people will shift job responsibilities, leave their position or graduate. When these changes occur, access to resources no longer required should be removed. This practice is known as deprovisioning and is key to protecting institutional data.
Supervisors should keep a list of job related resources that employees have been authorized to access; and inform system and application managers to deprovision the account when access is no longer authorized.
Data classification organizes institutional data into categories based on level of sensitivity, value and criticality to the University if the data is disclosed, altered or destroyed without authorization.
There are designated individuals at Carnegie Mellon with the Data Steward role. These individuals classify institutional data into three categories: public, private and restricted. It is important to know the type of data you interact with to understand your role in its protection.
Security Advisory: A Phish Email Titled “Your Computer will be suspended from CMU network” with an Attachment is Reported
Critical threats were detected in the Yosemite OS X (versions 10.10.4 - 5) operating system. One of the methods by which attackers use to exploit the operating system is going through untrusted applications from the web. Installing untrusted applications could allow attackers to gain access to the computer without using a password -- allowing them to take full control. The Information Security Office (ISO) recommends that those using the Macintosh operating system enable the Gatekeeper feature (built-in to Yosemite) for protective measures until Apple provides a software update to correct this issue.

On December 4, 2014 the Information Security Office (ISO) published an information notice titled “Scam Alert: Higher Ed is Target of Direct Deposit Thieves”. This notice can be found on the ISO’s home page at www.cmu.edu/iso. The article warned of phishing email attacks targeting schools for the purpose of stealing credentials and using them to alter the victims’ direct deposit information.
On Saturday, February 21, 2015, nearly 200 Carnegie Mellon users received a phishing email that appears to have been designed for this purpose. The email’s subject was, “Your Salary Raise Information”. A link in the message led to a well-crafted copy of Carnegie Mellon’s login page. After providing their login information, victims were redirected to campus web sites. Later, the attacker used a subset of the harvested login information to access Workday. Workday is the system used by employees (including work study and some grad students) for payroll, human resources and time tracking information.
While the investigation is ongoing, there is no evidence that any Workday data was modified and known victim accounts, of which there were relatively few, have been secured. Only data accessible to the individual victims’ accounts was ever at risk.
A weakness called GHOST in the Linux and Unix operating systems C library "glibc" allows attackers to take complete control of a compromised system. The GHOST vulnerability may affect many Unix and Linux systems including but not limited to Debian 7 (wheezy), Red Hat Enterprise Linux 6 & 7, CentOS 6 & 7, Ubuntu 12.04 & 10.10.

Many schools have experienced email scams that use harvested credentials to alter direct deposit information. These scams typically involve fake emails impersonating Human Resources or other university offices about salary increases, email storage limits, or connections from unexpected IP addresses. The emails include malicious links that when clicked, lead to login pages that are carefully crafted to look the same as the university’s login pages. Once someone provides their login id and password, the attacker uses them to access the victim’s payroll information to redirect direct deposits to a bank account. This is not a hypothetical situation. Faculty and staff at other institutions have lost their paychecks via this scam. While this hasn’t happened at Carnegie Mellon, analysts warn of a continuing trend.
Stay alert to scams like these. Confirm with Human Resources, the Information Security Office, or your supervisor before attempting to login if you are suspicious of any email.

Several university staff members reported receiving phone calls where individuals asked for their "HP number". When questioned, the caller typically hangs up. While "HP number" is unclear, it is possible that they are looking for the printers IP address, which might provide the scammer with remote access to the printer.
