Important Information About Internet Explorer - Vulnerability Fix Available

May 1, 2014

On Monday, April 28th, the United States Computer Emergency Readiness Team (US-CERT), part of the U.S. Department of Homeland Security, released a bulletin advising computer users of vulnerability within Microsoft Internet Explorer (IE). This vulnerability affects IE versions 6 through 11 and could lead to the compromise of an affected system.

Microsoft has released a fix for this vulnerability; more information about that release can be found here.

As always, it is important to help protect yourself from online threats, such as this. Below are some steps users can take to help protect themselves:

  • Install antivirus and antispyware software.
    Installing antivirus and antispyware software—and keeping it updated—is critical, even when there isn’t an imminent threat. Antivirus software detects and removes malware, including adware and spyware, and filters out potentially dangerous downloads and emails.

  • Apply all software updates.
    Be sure to install all of the latest software patches from Microsoft. It’s a vital, preventative step to a security routine. The latest Microsoft software updates can be found here.

  • Use Internet Explorer in "Enhanced Protected Mode."
    This enhanced security feature, which was first rolled out with Windows 8, helps stave off cyber criminals looking to alter system settings or install harmful software.

    1. To enable Enhanced Protected Mode in Internet Explorer 10 or 11, click the Tools menu and then click Internet options.
    2. In the Internet Options window, click the Advanced tab.
    3. Scroll down the list of options until you see the Security section.
    4. Look for the option to Enable Enhanced Protected Mode and click its checkbox to turn it on.
    5. If you're running IE 11 in a 64-bit version of Windows, you also need to click the checkbox to Enable 64-bit processes for Enhanced Protected Mode.
    6. Restart Internet Explorer to force the new setting to take effect.
  • Don’t click on suspicious links.
    Avoid suspicious looking URLs. Also, don’t open emails from anyone you don’t know, or even suspicious emails from someone you do know. If you accidentally open an email that contains suspect attachments or links, don’t click on or open any of them.

  • Disable Adobe Flash.
    Disabling the Adobe Flash plugin within Internet Explorer will prevent the exploit from functioning. Please be advised that if Adobe Flash is disabled, some of First Interstate’s online banking services may prompt you to answer security challenge questions before allowing you access into your account.

  • Use a firewall.
    Firewalls help safeguard computers by establishing a barrier between trusted, secure internal networks and other networks. Most computer operating systems already have a firewall built in. Make sure that it’s turned on to help further protect your computer from vulnerabilities.

Another protection is to use an alternative browser (such as Google Chrome) until a fix for Internet Explorer is available. However, if this option is chosen, users may experience reduced functionality in some of First Interstate Bank’s online systems, particularly our I-Corp Business Online Banking system. Specifically, Premier ACH and Remote Deposit, both available within the I-Corp product suite, are only compatible with Internet Explorer. Other online banking systems may have workarounds to function properly in another browser. For assistance in implementing these workarounds, please contact our Customer Support Center at 1-888-752-3332, Monday-Friday, 7:30am-6pm. Personal or small business assistance is option #2; corporate cash management products and service assistance is option #3.
