Security Alert: Mac OS X Yosemite (10.10.4 - 5) Vulnerable to Exploits

08/21/2015

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.

Security Alert: An email with a subject line "Problem with invoices" carries a malware infected attachment

06/12/2015

An email with the subject line "Problem with invoices" containing a malware infected attachment named "New.zip" is currently circulating at Carnegie Mellon University. When a recipient opens the .zip attachment and double clicks on the program inside, the malware is executed, infecting the computer system you are using if it is running any version of the Windows operating system. The malware is known to hijack your email credentials (Andrew UserID and password) and then attempt to spread itself by sending email from your system.

Security Alert:  Email Scam Targets CMU Employees for Potential Payroll Theft

02/25/2015

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.
