Seems like every week there is at least one headline reporting a security breach. In fact, Forbes recently reported a file located on the Dark Web contains 1.4 billion stolen passwords and usernames.
At the SHSU Information Security office, we constantly monitor these reports and assess threats to our campus community. In this case, we reviewed the information and found no notable impact; however, a few accounts did appear on the list and were immediately disabled. IT@Sam is working with the account owners to reset passwords and reactivate access.
Data thieves and hackers are becoming increasingly aggressive and sophisticated. It is more important than ever to protect yourself and the university. Below, are recommended best practices when creating passwords for online accounts:
Best Practices for Passwords
- Use a unique and strong password for each site you use.
- Use a password manager (i.e. KeePass, LastPass, 1Password, or Dashline) to keep track of all of your passwords and help you generate random, strong passwords when you need to.
- Change all your passwords regularly, even if the site does not require you to do so.
- Setup Two-Factor authentication if the site allows for it. This will add a layer of protection as the site will ask you to use a code sent to you via a text message or smartphone app as a second password.

National Cyber Security Awareness Month (NCSAM) – observed every October—was created as a collaborative effort between government and industry to ensure every American has the resources they need to stay safer and more secure online.
We lead Internet-connected, digital lives, even when we are not directly connected to the Internet. The Internet is a shared resource and securing it is Our Shared Responsibility. Everyone has a role in securing their part of cyberspace, including the devices and networks they use.
Throughout the month, IT@Sam will share tips and resources to help you implement stronger security practices. Together we can create a digital society that is safer and more resistant from cyber-attacks.

News headlines are referencing a global ransomware attack. Ransomware is a type of malware that is usually delivered via an email attachment or link to a malicious website. When this malware is unintentionally activated by a user, it begins to encrypt all the files that the user has access to and then informs the user that they have to pay a ransom in bitcoin (an online currency) to decrypt the files. Until this is done, the only recourse the user has is to restore the files from a backup if there is one available, or if not, the user unfortunately pays the ransom. Often times, even when the ransom is paid, the hacker does not decrypt the files. This is why it is imperative that users backup their data, like IT@Sam does with the SHSU servers. Previous ransomware attacks against the university that made it past security controls were thwarted by IT restoring files to a previous version, usually from the day before.
A key difference with these ransomware attacks (yes, there are multiple variants from different hacking groups) is that they are not just encrypting files that the user have access to, rather they are exploiting a vulnerability in Microsoft Windows to encrypt all files hosted on every server or workstation that is vulnerable. Microsoft released a patch for this vulnerability in March 2017. At that time, IT@Sam patched systems that were know to be vulnerable.
However, on April 14th, 2017, a group of hackers known as The Shadow Brokers released a set of hacking tools that were stolen from the NSA. These hacking tools contained an exploit for the Microsoft vulnerability, meaning that with a push of a button, anyone could attack vulnerable servers and workstations, even if the user doesn’t have permissions to the files. IT@Sam decided to take immediate action on all servers to ensure they would not be vulnerable. This critical updated occurred during working hours and did disrupt a few services on campus last month, but they were quickly rectified.
These current ransomware attacks are using these hacking tools to encrypt all files they can where Microsoft has not been patched. Many organizations have not yet applied patches and are being negatively impacted. SHSU takes its security posture seriously, and makes it a point to be better safe than sorry. IT Security has rescanned the entire campus network, and no servers are reporting as vulnerable to this attack. A handful of workstations are vulnerable and are under investigation.
It is important to practice caution when opening attachments in emails or clicking on links as these are the methods used to begin these attacks. IT Security has taken the threat intelligence it has at this time to block known email subjects from entering SHSU’s email system and the campus Intrusion Prevention System (IPS) has rules in place to detect and block the malware that is currently known at this time. However, these can change rather rapidly which is why the IPS system gets updates automatically from the vendor to stay up to date. No security is 100%, but we will continue to monitor the situation as more information is released and take the appropriate actions to swiftly protect the students, faculty and staff of the SHSU community.

More and more cybercrimes occur every day over the world. Unfortunately, many
people are still unaware of the dangers that lurk just around the mouse click.
It is for this reason that, over the past few years, Homeland Security has made
it a priority to bring cyber awareness to the masses. With the help of various
organizations they are able to reach a vast number of individuals. That is why
SHSU will participate in National Cyber Security Awareness Month with other
organizations across the country. Read More.
At least one agency in the Texas State University System has been the target of two attempted social engineering events in the past few weeks. We want to make sure that you are careful with the information that you provide to those that contact your department.
Social engineering is a means of manipulating a person into releasing information or performing acts that will give another person access to secure information. A lot of times the person being manipulated may not realize what is happening until well after the information is given out.
For additional information on this topic including steps to help you avoid being a target, read the July 2012 Cyber Security Tip Newsletter published by the Texas Department of Information Resources. Additional information can also be found on the United States Computer Emergency Readiness Team site.
If you feel you have been the target of social engineering, please do not hesitate to contact IT@Sam to report the issue.
