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.

A phishing email titled "SCAN" that includes a malware-infected attachment titled "scan3434.zip" is circulating at Carnegie Mellon University. Once a recipient clicks on the attachment the malware is executed, and the email client is compromised, sending copies of the email (and the attachment) to all contacts.

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.
A vulnerability has been announced for most web browsers that could enable the disclosure of private information during a "secure" web session (https), such as a shopping, banking, enrollment or mail viewing session, where you'd normally expect secure, encrypted traffic.

Announced on April 7, 2014, a security vulnerability called Heartbleed allows attackers to collect information that is expected to be encrypted including encryption keys, session cookies, credit card numbers, passwords, and social security numbers. Computing Services Information Security Office (ISO) is actively scanning CMU's network for vulnerable hosts, monitoring for evidence of attack and compromise, and responding to impacted individuals accordingly. University vendors are also being assessed.

Microsoft plans to end support for Windows XP on April 8, 2014. There have been a number of advisories from various sources indicating that shortly after the end of support, a rash of malware and exploits will be released targeting the XP operating system. Accordingly, the Information Security Office (ISO) will begin scanning for XP computers on campus or connected to campus services on Thursday, March 20, 2014.

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.
