Information Technology Updates

I wrote about ransomware about a year ago. The only things that have changed since then are that the result of becoming infected have gotten far more severe and the number of victims has increased exponentially. Today's variants not only encrypt your data and demand payment to decrypt it, they also steal your data and threaten to expose it to the world if payment is not made. Under that scheme, even if you have proper and sufficient backups to restore your data, making the encryption moot, there is the threat that your data will be published for all to see.

We are not immune from these attacks here in the midwest. Last fall, the University of Nebraska Medical Center and Nebraska Medicine were breached. Associated costs are many tens of millions of dollars. More recently, and even closer to home, DMACC suffered a ransomware attack early last month that shut their network and classes down for almost two weeks.

Phishing provided the initial foothold for the bad actors behind these and many other similar incidents. Vigilance and skepticism when reading email remains key. Don't fall for the emotions that all phishing actors try to evoke -

  • Fear - something bad will happen if you don't click on the link in the message
  • Greed - something good will happen if you do click on the link in the message
  • Urgency - hurry up and click on the link in the message right now
  • Concern/Empathy -
    • I’m stranded in an unfamiliar city
    • I’m falsely accused, in jail, and need bail money
    • I’ve been mugged and am in the hospital

Don't click on links in email messages unless you're certain they are legitimate. Don't open attachments in email messages unless you're certain of the sender's identity and the content of the message makes sense to you. If you have any questions about the message, err on the side of safety and seek help by contacting security@uni.edu.

On June 18th Information Technology will replace the security certificate used to secure connections to Eduroam WiFi on campus. All UNI-owned and managed devices will be automatically reconfigured for the new connection and nothing will be required. However, personally owned laptops, tablets, and smart phones will potentially be asked to accept a new security certificate the first time they connect to Eduroam WiFi on June 17th. These prompts could look something like the screen captures below.

If you have questions or trouble connecting to Eduroam WiFi on campus, please visit this IT support article. You can also contact your IT support by submitting a "Get IT Help" request from the Service Hub Portal.

Vishing is to your phone as phishing is to your email account. Vishers may use either voice or SMS (text messages) to target you. They do this because there is less protection for your phone than for your UNI email account. Read the SANS OUCH! page at https://www.sans.org/newsletters/ouch/vishing/ for details and advice.

In an announcement earlier this calendar year, Google notified their education customers that they are changing the rules regarding storage for their Google Workspace for Education product line to no longer include unlimited storage space. Although Google has traditionally offered unlimited storage for free to its education customers, this model has become unsustainable with the rapid acceleration in growth of stored data. In July of 2022, Google will shift from unlimited storage to a pooled storage model for Google Workspace for Education customers.

This shift in strategy by Google means that UNI will need to reduce it’s overall storage consumption across Gmail, Google Drive (both My Drive and Shared Drives), and Google Photos in the Uni.edu Google domain prior to the July 2022 deadline. Information Technology (IT) is working closely with Google to ensure we have the tools and resources necessary to help us make this transition as smooth as possible.

IT will be communicating soon with users across campus who are using significantly more storage as compared to the average in our domain to understand their needs and work with them to clean up old and unneeded files and data. IT will continue to share information and answer questions as this project progresses. In the meantime, if you’re interested in seeing how much storage you’re using with your UNI Google account, or to find out how to reduce your overall storage usage, you can review this knowledge base article.

A W2 tax email scam is circulating in the U.S. using Typeform, a popular software that specializes in online surveys and form building. The campaign is aimed at harvesting victims’ email account credentials, researchers said.

According to Armorblox, the campaign also bypasses native Google Workspace email security filters in the victims it examined.

“The email impersonated an automated file-sharing communication from OneDrive, informing victims that they had received a file,” researchers explained in an analysis on Tuesday. “The email was sent from a Hotmail ID and was titled ‘RE: Home Loan,’ followed by a reference number and the date, making it seem like the email was part of an ongoing conversation to lend it more legitimacy.”

What is Identity Theft?  Identity theft happens when a criminal steals information about you and uses that information to commit fraud, such as requesting unemployment benefits, tax refunds, or a new loan or credit card in your name. If you don’t take precautions, you may end up paying for products or services that you didn’t buy and dealing with the stress and financial heartache that follows identity theft.
