iOS 9.3.5 Security Update

Apple recently issued a patch to fix a dangerous iOS security vulnerability. The update is available for iPhone 4s and later, iPad 2 and later, and iPod touch (5th gen) and later. Note that IMSS-managed mobile devices will be automatically updated if the end user accepts the update. Others should also be prompted by iOS to update, but can also manually do so by opening Settings > Gen...

Zip files quarantined by Office 365/Exchange

IMSS would like to remind Office 365 and IMSS Exchange users that incoming messages containing .zip files will have the attachment quarantined. This change was made several months ago in response to a marked increase in malicious .zip attachments. If necessary, however, quarantined attachments may be retrieved by contacting the Help Desk (x3500, help@c...

Mail from *.top is no longer accepted

IMSS has updated its servers to silently reject mail from the '.top' domain in an effort to reduce the amount of spam we receive. For questions, please contact us (x3500, help@caltech.edu, https://help.caltech.edu).

Undeliverable Notifications may be due to Email Spoofing

IMSS has received reports of people receiving bounce-back undeliverable notifications that suggest they sent an email containing malware. Some people have been alarmed because they know they did not send the original malicious message. Most likely, the email address was spoofed, which means a spammer forged the “from" email address to mislead the recipient about the orig...

Check your Junk Mailbox Regularly

IMSS would like to remind you to regularly check your Junk mailbox for messages that may have been incorrectly tagged as Spam. While we do our best to ensure that legitimate messages arrive in your Inbox, the recent increase in malware has resulted in the likelihood of more valid messages ending up in Junk. For questions or concerns, please contact us (x3500, help@caltech.edu, http...

New Login Page for Box, software.caltech.edu, CardQuest, and Blackboard

Effective August 2, the login pages for Box, software.caltech.edu, CardQuest, and Blackboard will have a new look. Note that the login process will remain the same, but the login page will also include helpful links and a look that coordinates with access.caltech. The new login page will appear, as below. For questions, please contact the Help Desk (x3500, help@caltech.edu, https://help...

Don't let ransomware disrupt or destroy your work

Ransomware is a category of malicious software that is becoming increasingly widespread.  It differs from other kinds of malicious software in that its primary purpose is to render the victim's data files unusable (typically by encrypting them) until a "ransom" in difficult-to-trace virtual currency such as Bitcoin is paid. Organizations all over the world, including ...

"IMSS Help Desk" email message is a phisher scam

Many people received a scam message this morning that looks like it came from the IMSS Help Desk, indicating that two e-mails have been placed on hold. This message is a fake, and points to a fake Caltech login page. However, if you look at the address bar in your browser, or hover over the URL before clicking, you will see the website is not a Caltech website address at all. It has been blo...

Removal of Flash from Managed Computing systems

IMSS is currently working with Managed Computing customer groups to coordinate the removal of Adobe Flash Player from all Managed Computing systems. We are doing this because of numerous ongoing and severe security vulnerabilities from using Flash. While Flash was previously a popular plugin, many websites, such as YouTube and Pandora, have since moved away from Flash and transitioned to usi...

OneDrive for Business sync client issue

After a recent Microsoft update, the OneDrive for Business sync client is experiencing issues. Users that have mounted OneDrive for Business on their local computers will be unable to create or save changes to the documents stored there. Until the issue is resolved by Microsoft, a temporary workaround is to create and edit Office documents in a web browser. To do this, log in with your Calte...

Phisher scam pointing to fake access.caltech site

A message titled "New Message Notification" telling users to log into access.caltech "for immediate update" points to a fake website that is an exact duplicate of https://access.caltech.edu. Mousing over the link without clicking will reveal that the link actually points to a .com site, which has been notified. The fake website is blocked from campus, but off-campus recip...

Fake "Notice to Appear in Court" message

An email message with the subject line "Notice to Appear in Court" has been received by some campus users. Not all antivirus software can currently detect the included .zip attachment. If you receive such a message, please delete it. Do not attempt to open the .zip attachment, which contains a malicious javascript file intended to look like a Word document. For questions, please co...

Below is a temporary workaround.

IMSS recommends upgrading Eudora email clients

After a recent update to campus email, the Eudora email client is no longer compatible with the standard UNIX mail system. Customers using Eudora may no longer be able to access their mailbox. Since the latest version of Eudora was released in 2006, it is unlikely that we will find a solution for customers to continue to use Eudora. IMSS instead suggests upgrading to Beware Fake IRS Emails

Tax time brings IRS scam email messages.  A variety of scams are circulating in email right now purporting to be important messages from the IRS.  Be very suspicious of any incoming email message that claims to be from the IRS, particularly if it includes an attached document.  One current example is a message claiming to provide information about a tax refund, in the form of ...

Don't Be Fooled By Messages Asking For Your Caltech Username And Password

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 ...

Java 8 Update Information

Java users may have recently auto-updated or received prompts to update from Java 7 to Java 8. Though Java 8 is currently the default version on http://java.com, Caltech users may want to reconsider updating to Java 8 due to compatibility issues with some applications. If the Caltech administrative applications are an integral part of your workflow, IMSS does not recommend updating at this t...

Effective February 9, 2015, the IMSS-run proxy server which registers campus Red Hat systems to receive updates will be retired and transitioned to a new Satellite server.

This will ensure that your Matlab network installation accesses the new replacement license server. For instructions on how to obtain and update this license file, Bash "shellshock" vulnerability

A security problem with Bash was publicly disclosed on Wednesday, 9/24. Bash is a very popular operating system component known as a "shell" that comes with all versions of Linux and Mac OSX, as well as other systems. While this vulnerability has been present for many years, it was only discovered recently. As soon as IMSS became aware of the problem on 9/24, core IMSS sy...
