Caltech's site subscription for LabArchives is in the process of being renewed. While we work to complete this renewal, please disregard any warning notices that the subscription is expiring.
Many campus users are receiving email claiming to come from an IT support group (sometimes even IMSS or the Help Desk), asking for the user's password and other private information, or requesting that you "verify your account" by logging into a website. Please be aware that this is a form of security attack known as "phishing" designed to fool users into giving their usernames and passwords to an attacker. Please do not reply to these messages or visit any websites they may refer to. IMSS does not recommend providing usernames and passwords by email, and IMSS will never ask users for their passwords by email or by phone under any circumstances. When visiting a website, be sure to check the address bar on your browser to confirm that the site you're visiting is the one you were expecting. If you receive any confusing or worrisome email messages about any of your Caltech accounts, we strongly recommend contacting the IMSS Help Desk (395-3500 or http://help.caltech.edu) or your local system administrator. In the event that your password is exposed to an attacker, please be sure never to use that password again, for any purpose, and particularly never for the account it once belonged to.
Standalone Matlab licenses expire annually on December 1. To renew your standalone Matlab license for another year, follow these instructions.

Once you have started the activation process, follow these steps:
- Select "Activate automatically using the Internet", and click "Next".
- Log in with your MathWorks account by filling in your credentials and clicking "Next".
- Select your license number from the list that appears, and click next.
- Use the standalone key you used to activate the product. You can retrieve this key from your software.caltech.edu purchase receipt.
- Submit your activation by clicking "Activate".

Several of the applications that IMSS maintains will soon be optimized to use Java 7. IMSS urges you to update to the latest version of Java 7 immediately to avoid problems with using these Java-dependent applications, as well as protect your computer from using older and insecure versions of Java. Instructions on how to download and install Java 7 can be found at http://www.java.com/en/download/.
IMSS also recommends uninstalling Java 6, which is not automatically removed when updating to Java 7. Instructions to uninstall older and insecure Java versions can be found at:
- Windows: http://www.java.com/en/download/help/uninstall_java.xml
NOTE: To avoid issues with uninstalling Java 6, IMSS recommends installing Java 7 first, restarting your computer, and then uninstalling Java 6.
Additionally, IMSS recommends downloading and installing a custom Java configuration file on your computer. Installing this configuration file will further assist with security and compatibility with IMSS applications and it will prevent persistent, yet harmless, security warnings from appearing when using specific IMSS applications. Instructions for downloading and installing this file can be found at http://imss.caltech.edu/help/java-config-file.
Also note that in order for some IMSS applications to work with Internet Explorer 10, compatibility mode must be enabled. Instructions for setting up compatibility mode can be found at http://imss.caltech.edu/help/enabling-compatibility-mode-ie10.
Kronos is one of the applications that will be optimized to use Java 7. IMSS would like to remind you that you can avoid any potential issues with Java by using Kronos Limited instead, which does not require Java to run. To use Kronos Limited, go to http://kronoslimited.caltech.edu.
As a final note, IMSS managed computing customers were updated to Java 7 and had the custom configuration file installed during our maintenance window on 11/14, and therefore will not need to take any further action.
For questions or further advice, please contact the Help Desk (x3500, https://help.caltech.edu.)
There has been a recent resurgence of a type of malicious ransomware software known as "CryptoLocker." The CryptoLocker family of malicious software arrives as an email message that is intended to look like legitimate email from a known sender. The message includes a .zip attachment containing a Windows program disguised as a PDF that, when opened, will encrypt files on the victim's hard drive as well as any mapped network drives where the victim's account has write permissions. The victim is then prompted to send an electronic ransom payment to the attacker in order to get a decryption key.
- Exercise caution with unexpected email attachments and their contents, and be aware that they can be disguised as other types of files.
- Remember that sender information on an email message can be falsified.
- Maintain up-to-date backups. A good backup is critically important if you've already been affected.
- Using an unprivileged (non-Admin) account for routine computing.
Implementing a Software Restriction Policy to confine program execution to specified hard drive locations, rather than allowing program execution from arbitrary locations such as mail folders.
Note: IMSS Managed Computing systems use both of these measures to help protect against infection.
IMSS has resolved the issues with obtaining Red Hat updates. As of 10/17, Red Hat updates are available. If you are still unable to receive updates, please submit a support request at https://help.caltech.edu (request type IMSS > IO Applications - UNIX/Linux).
Due to serious security and compatibility issues with Java, IMSS recommends using Time Keeping (Kronos) Limited instead of regular Time Keeping (Kronos). Time Keeping Limited, the lighter version of Time Keeping, does not require Java and is compatible with all common operating systems and browsers. Time Keeping Limited can also accomplish the same common tasks and functions as regular Time Keeping for employees and managers.
As a reminder, IMSS strongly recommends using Java only when absolutely necessary and frequently keeping up on security updates. Note that IMSS regularly maintains Java on all Managed Computing PCs.
For questions or concerns, please contact us at http://help.caltech.edu using request type IMSS > Applications-Self Service > Time Keeping (Kronos) > Other.
Effective Monday, February 25th, the Help Desk and Hardware Repairs are now located in Central Engineering Services (building 85.) The Help Desk is located in Room 204 and Hardware Repairs is in Room 109. Also note that our new mail code is 200-85.
For several years, IMSS has provided Blackberry Enterprise Services (BES) for Caltech customers who wish to integrate Blackberrys with IMSS Exchange to sync their email, calendars, contacts and tasks. Please note that IMSS will continue to provide BES services to existing Blackberry customers for approximately one year, but we are no longer adding Blackberry devices to our current BES service. Blackberry 10, Blackberry's newest mobile operating system, can natively sync with IMSS Exchange, so BES is no longer necessary to use Blackberry 10 devices at Caltech.
We are making this change in response to the declining number of campus Blackberry customers. With the increasing popularity of iPhone and Android devices at Caltech and elsewhere, we believe this is the most efficient use of our resources. We encourage current BES customers to consider switching to an iPhone, Android or Blackberry 10 at their next opportunity (i.e. when you become eligible for upgrade or your contract is complete and you plan to move to a new wireless carrier). BES customers who wish to keep their current Blackberrys for more than one year will need to migrate to their wireless carrier's Blackberry integration services, commonly known as BIS.
For information on mobile devices and service plans, please contact the Telecommunications Office (x5995). For assistance setting up your mobile device, please contact the Help Desk (x3500, http://help.caltech.edu).
IMSS recommends using the "Find Me" function in iCloud to be able to locate your Apple mobile devices in the event they are lost or stolen. For information on how to set this up, visit http://www.apple.com/icloud/features/find-my-iphone.html.
