The Information Security Office wants to alert students, faculty, and staff of a type of phone scam called Vishing (voice phishing) which uses fake caller-ID data to give the appearance that calls come from a trusted organization (such as UT Arlington). The caller tells people they owe money to the University and a warrant has been issued for their arrest. Next, the caller solicits immediate payment for the alleged debts.
University officials will not contact you in this manner or threaten arrest for non-payment of debts. Verifying UT Arlington debts, including citations, can be done by checking MyMav or visiting the Bursar directly. Be aware that this is a type of social engineering wherein someone uses influence, deception, and persuasion to get information that would otherwise be unavailable to them (which is also known as fraud).
Caller ID is far from proof positive of a caller’s identity or authentication. Don’t trust incoming calls based on Caller ID. Make 100% sure you know to whom you are speaking. If any incoming calls from supposedly legitimate companies ask for any personal information of any kind… it is a scam. It is fraud. Period.
If you receive an unexpected call like this from someone claiming to be from UTA DO NOT provide your credit card information. If you fall victim to the call, contact UT Arlington’s Police Department at 817-272-3381. For information on preventing social engineering and theft, please contact the ISO at firstname.lastname@example.org or call us at 817-272-5487.

The Information Security Office wants to make you aware that a number of vulnerabilities affecting Microsoft Office and Adobe Acrobat were disclosed this week. Furthermore, we have been made aware that savvy criminals are launching phishing campaigns to deliver malware (such as viruses, Trojans, worms, etc.) by sending specially crafted documents (like pdf, PowerPoint) attached to crafted email designed to bait recipients into opening the documents. If the document is opened, there is a potential for the computer to be infected and may begin downloading other malware.
The Office of Information Technology is aware of these vulnerabilities and is in the process of mitigating them by doing the following:
1. Updating the malware signatures on the email systems that deliver email to @uta.edu and @mavs.uta.edu addresses to block known attachments that might be infected.
2. Updating Microsoft Endpoint Protection (Windows) and McAfee Antivirus (Macintosh) to block known malware that might exploit this vulnerability.
3. Updating Microsoft Office and Adobe Acrobat products on computers that have the standard OIT image.
4. Patching vulnerable servers under their care that might be vulnerable if malware entered our network.
Additionally, the Information Security Office has implemented blocks on the Intrusion Prevention System for known communication that might exploit these vulnerabilities.
As is the nature with all anti-malware software or network protections, and while anti-malware vendors are constantly adjusting and improving detection capabilities, they are often playing catch-up with the latest techniques used by criminals to evade threat detection technology. As such I encourage you to alert your staff to be vigilant and to follow these general tips to avoid infection:
- Do not open email attachments from unknown or untrusted sources
- Remind users not to visit untrusted websites or follow links provided by unknown or untrusted sources, especially email.
- Ensure that computers and servers are protected:
- Keep all operating system, applications and essential software up to date to mitigate potential exploitation by attackers.
- Make sure all AV products are up-to-date with their signatures.
- Ensure that there is a properly configured firewall enabled on the computer or server.
If you are not sure whether your UTA computer is fully protected, please contact the OIT help desk or your Desktop Support Associate.
The Microsoft Security Advisory (found here) describes a new, un-patched vulnerability in all currently supported versions of Windows except Server 2003. Successful exploitation of this vulnerability would allow an attacker to gain the same rights on the machine as the current user.
Exploitation of this vulnerability requires the user to open a specially crafted Microsoft Office document. Researchers are seeing targeting attacks utilizing this attack.
Prevention: standard behavior rules apply:
- Don’t open attachments from unknown sources
- Don’t click on suspicious links in email
Also known as “Poodle”, this vulnerability could allow an attacker to steal web site login information or payment data.
“A vulnerability exists within the SSL version 3.0 protocol… allowing an attacker to hijack and decrypt session cookies that are utilized between a user’s web browser and the web site. This could lead to attackers obtaining enough information to temporarily impersonate web site visitor account logins and/or online payment systems.”
Several important vulnerabilities in Microsoft products, including Windows, Office, .NET, Internet Explorer, were released today along with patch information. They are:
- Vulnerabilities in .NET Framework Could Allow Remote Code Execution (MS14-057)
- Vulnerabilities in Kernel-Mode Driver Could Allow Remote Code Execution (MS14-058)
- Vulnerability in Microsoft Word and Office Web Apps Could Allow Remote Code Execution (MS14-061)
- Cumulative Security Update for Internet Explorer (MS14-056)
- Vulnerability in OLE Could Allow Remote Code Execution (MS14-060)
- Multiple vulnerabilities found in Adobe Flash Player and Adobe AIR could allow an attacker to execute code remotely. (APSB14-22)
- Critical Oracle Patches (http://www.oracle.com/technetwork/topics/security/cpuoct2014-1972960.html)
These Security Advisories will affect many users; student, staff and faculty; so it is important to update your instances of the software mentioned.
