Google Chrome PDF Policy Change

Michigan Tech IT is changing how Google Chrome handles PDF files on Windows PCs. 

The ability to view the file in Chrome is currently disabled, forcing you to download the file to your computer and open it in Adobe Acrobat. This accommodation was for Michigan Tech forms with auto-expanding text boxes that did not work correctly with Chrome’s built-in PDF viewer. Examples include the Staff Hiring or Yearly Performance Management worksheet.

If you tried to open the form in Chrome you would see the following message:

This message was confusing and uninformative. It said you should install Acrobat Reader, even though you already had the full Acrobat Professional application installed. To avoid confusion, Michigan Tech IT disabled Chrome from viewing PDFs and forced downloading the file. 

The change produced widespread and unintended consequences. It changed the familiar viewing method on personal computers and broke the Google Sheet print function used by students. Furthermore, it caused problems with Concur.

For these reasons, we are reverting Chrome to its default behavior. 

After selecting a PDF link, Chrome will attempt to display it in the web browser. If the PDF file contains auto-expanding text boxes, the “Please wait…” message will display. Download these PDFs and open them in Acrobat. View the download icon below:

Michigan Tech departments that have PDF documents with auto-expanding text boxes should configure their website to force the download of the file rather than allowing the browser to decide how to handle the file.

Protecting Electronic Payments

Online sales in the United States grew to a record high of nearly 19 percent during the 2019 holiday season.1 At the same time, the convenience of using credit cards and other electronic payment services is compelling consumers to rapidly reduce their use of cash. The 2019 Diary of Consumer Payment Choice report shows that cash is used about 50 percent of the time for in-person transactions under $10 (for things like lunch or coffee).2 For larger purchases of $25 or more, cash is used only 10 percent of the time. Cybercriminals are taking advantage of the increase in electronic payments. According to the 2020 Cybersecurity Report from Check Point Research, mobile banking malware attacks increased 50 percent from 2018 to 2019.3 Here are some tips to help you safely use electronic payment sites.

  • Verify websites before entering important information. Clicking on a link may not take you where you expect to go. When shopping, banking, or making payments online, manually type in the website name (e.g., chase.com) instead of clicking on links in an email, social network post, or text message.
  • Look for deceptive emails and texts. Your bank or electronic payment processor won’t ask you to provide personal information or passwords via email, but scammers will. Watch this Consumer Reports video for examples.
  • Ignore phone calls from unknown and unfamiliar numbers. If you receive a phone call from someone who is urgently asking for money, there’s a good chance it’s a scam. Most of these calls can be safely ignored, but if you want to check, search for the organization’s website and find out for yourself. Don’t be rattled by threats over the phone.
  • Look for the lock icon in your browser. The lock icon in the address bar of your web browser shows that the website you’re visiting sends data in encrypted form. Never send money or pay for goods on a site without this important safeguard.
  • Public computers aren’t for private information. The computers in a hotel lobby or a public library may have a virus that records your activity, including any passwords you enter. Shop and make electronic payments only on a computer that you control.
  • Don’t use free Wi-Fi when making an electronic payment. The open nature of free Wi-Fi at cafes, airports, and other public venues makes it possible for others who are on the same Wi-Fi network to spy on your activities. If you cannot wait for another time to do your banking, use a VPN when using free Wi-Fi.
  • Consider getting a credit card just for electronic payments. If you decide to get a credit card or online account just for electronic payments, make sure the credit limit or available balance is low. This can protect you from a large loss due to online fraud.
  • Review your transactions regularly. Online banking allows you to check your account quickly and easily. Take time each day or each week to quickly review electronic payments. If you see charges you don’t recognize, notify your bank or payment application vendor (e.g., Venmo, PayPal, or Apple Pay) as soon as possible.
  • Check your credit reports to help spot fraud. Credit reporting services Experian, Equifax, and TransUnion are required to provide you with a free credit report once per year, so try to check one report every four months.4
