To resolve remaining concerns with the Exchange Virtual Machines, at 5:00 pm today the email group will take the Exchange servers offline so the server group can shutdown the servers and reboot the VMWare ESX hosts.  This will create approximately 30 minutes of downtime impacting the services below.

Impacted Services:

  • N.O. - All mailbox services
  • HCSD – internet mail, inter-site mail, and off network client access
  • SHV – internet mail and inter-site mail

 

Date Posted: 04/22/17 2:12 PM

Supporters,

We are again having issues with the Virtual Machines hosting our Email servers.  Some users will be unable to access their mailboxes, and there will be some delays in message delivery.  We are working with the Server Group to resolve.

Booby-trapped Word documents in the wild exploit critical Microsoft 0day

There’s currently no patch for the bug, which affects most or all versions of Word.

Dan Goodin  -  

Ars Technica | 4/8/2017, 3:00 PM 

There's a new zeroday attack in the wild that's surreptitiously installing malware on fully-patched computers. It does so by exploiting a vulnerability in most or all versions of Microsoft Word.

The attack starts with an e-mail that attaches a malicious Word document, according to a blog post published Saturday by researchers from security firm FireEye. Once opened, exploit code concealed inside the document connects to an attacker-controlled server. It downloads a malicious HTML application file that's disguised to look like a document created in Microsoft's Rich Text Format. Behind the scenes, the .hta file downloads additional payloads from "different well-known malware families."

The attack is notable for several reasons. First, it bypasses most exploit mitigations: This capability allows it to work even against Windows 10, which security experts widely agree is Microsoft's most secure operating system to date. Second, unlike the vast majority of the Word exploits seen in the wild over the past few years, this new attack doesn't require targets to enable macros. Last, before terminating, the exploit opens a decoy Word document in an attempt to hide any sign of the attack that just happened.

The zeroday attacks were first reported Friday evening by researchers from security firm McAfee. In a blog post, they wrote:

The exploit connects to a remote server (controlled by the attacker), downloads a file that contains HTML application content, and executes it as an .hta file. Because .hta is executable, the attacker gains full code execution on the victim's machine. Thus, this is a logical bug [that] gives the attackers the power to bypass any memory-based mitigations developed by Microsoft. The following is a part of the communications we captured:

The successful exploit closes the bait Word document and pops up a fake one to show the victim. In the background, the malware has already been stealthily installed on the victim's system.

The root cause of the zeroday vulnerability is related to the Windows Object Linking and Embedding (OLE), an important feature of Office. (Check our Black Hat USA 2015 presentation in which we examine the attack surface of this feature.)

FireEye researchers said they have been communicating with Microsoft about the vulnerability for several weeks and had agreed not to publicly disclose it pending the release of a patch. FireEye later decided to publish Saturday's blog post after McAfee disclosed vulnerability details. McAfee, meanwhile, said the earliest attack its researchers are aware of dates back to January. Microsoft's next scheduled release of security updates is this Tuesday.

Zeroday attacks are typically served only on select individuals, such as those who work for a government contractor, a government agency, or a similar organization that's attractive to nation-sponsored hackers. Still, it's not uncommon for such attacks to be visited on larger populations once the underlying zeroday vulnerability becomes public knowledge.

People should be highly suspicious of any Word document that arrives in an e-mail, even if the sender is well known. The attacks observed by McAfee are unable to work when a booby-trapped document is viewed in an Office feature known as Protected View. Those who choose to open an attached Word document should exercise extreme caution before disabling Protected View. There's no word yet if use of Microsoft's Enhanced Mitigation Experience Toolkit prevents the exploit from working.

We continue to work with Veritas Enterprise Vault Technical Support to make sure this problem is fully resolved.   With their guidance, we have implemented some steps we believe may resolve the issue.  At this time archive file Recalls are again enabled, and the system appears to be stable.  We continue to monitor the situation.  Please report any new issues to the Help Desk.

 

Date Posted: 03/31/17 10:59 AM

Unfortunately, in order to stabilize the responsiveness of ENTFILESRVR and of Citrix, we have had to stop and disable the Enterprise Vault File System Archiving Services on ENTFILESRVR.    The result is that for the time being it is not possible recall any archived file (one with a gray icon overlay in the lower left corner) simply by double-clicking it).    Users who have an urgent need to recall a file should contact Enterprise Server Support or the Help Desk, and we will do our best to assist with the request, while we are also working the primary issue.

 

While it is possible that tonight’s scheduled reboot of ENTFILESRVR may help resolve this issue, we will go ahead and open a case with Symantec in case it does not.

It has come to our attention that some LSUHSC-NO employees have been victimized by a sophisticated phishing scam that resulted in fraudulent IRS tax returns being filed under their names.  More information about these scams can be found on the following IRS web page:

https://www.irs.gov/uac/newsroom/irs-states-and-tax-industry-warn-of-last-minute-email-scams

If you believe you may have been a victim of such a scam, additional information and resources can be found on this IRS web page:

https://www.irs.gov/individuals/identity-protection

To address the serious problem of identity theft, LSUHSC-NO IT is planning to implement multi-factor authentication (MFA).  MFA is used by online websites that seek a second level of authentication to verify your identity and prevent hackers from gaining access to your personal information, even if hackers have acquired your user ID and password through a scam.  In the meantime, LSUHSC-NO reminds all employees that phishing scams are at an all-time high and every email should be treated with a healthy degree of skepticism, especially emails that come from outside the lsuhsc.edu network. Questions to ask oneself when evaluating an email include but are not limited to the following:

  • Was the email unexpected? (i.e. There was no earlier email or other announcement letting you know to expect this message or the message is not part of the normal business routine.)
  • Is the sender a title rather than an individual’s name? (e.g. from "HR Department" instead of the name of the HR director) Does the message start with "*EXTERNAL EMAIL: EVALUATE*"?
  • Does it ask you to take an action such as clicking on a link or an attachment, or transferring funds?
  • Does it ask for your username and password?
  • Does it create a sense of fear or urgency by stating or implying dire consequences for failing to act (e.g. access will be suspended, important document attached, etc.)?

 

If the answer to any of these questions is "Yes", send the email as an attachment (CTRL+ALT+F) to SPAM@lsuhsc.edu or contact your IT supporter for investigation.  Do not, under any circumstances, use any of the links or rely on any information from an email you feel may be suspicious.

More information about phishing emails is available in your HIPAA Security – Social Engineering training on KDS. If you have completed the training and would like to review the lesson’s content, you can do so at the following link:

http://www.lsuhsc.edu/administration/ocp/docs/HIPS-SE.pdf

Remember:

  • We don’t know your password and don’t need to know it to get our job done. We, or any legitimate site, would never ask for it, especially in response to an email.
  • Be very suspicious of requests to verify your account or mailbox for any reason, particularly due to exceeding limits or preventing deactivation. LSUHSC IT knows owner and access information and does not need to ask you this in an email.
  • Never divulge your SSN, bank account, or other such sensitive information via an email. LSUHSC-NO already has all the information needed for administrative purposes. Legitimate sites will not ask for this information via email.
  • Be suspicious of any email asking you to click on a link. Clicking on a link could install malware on your computer to be used by the perpetrator to gain access to the LSUHSC network.
  • Hover your cursor over all links in the email to determine if any of the URLs go to a web address other than the proposed sender’s site before clicking on the link.

 

Your user ID and password contain the keys to your identity. Keep your password confidential.

We are receiving emails about two major issues, with Office 365, today from supporters and students

1. Students in Office 365 that are not appearing in the GAL

2. Students unable to access their email.

We are presently working on this issue. We will send out updates as they occur.

 

Date Posted: 03/28/17 9:56 AM

We need to complete an additional upgrade to our Enterprise Vault File System Archiving software, this time from version 10.0.4, to version 11.0.1.  We are proposing Thursday, March 30th, at 5:00 pm to begin the upgrade process, which we expect will require about 2 - 3 hours of downtime.   During the proposed maintenance, it will not be possible to recall individual files from the archive, and we will not be able to process any requests for completing "bulk recalls" of all files within a particular folder tree.   

By design, the only files that have ever been eligible to be archived are those files that no one has accessed in at least 6 months, so any files that you have viewed or modified in the recent past should remain accessible throughout this maintenance.    Only those files that have not been accessed in more than 6 months, and then were archived, will become unavailable for the duration of the maintenance.

Once the maintenance has completed, you will again be able to retrieve individual archived files simply by double-clicking their icons, without any need to take any additional steps on your workstation.   There will be no change to the end user experience as result of this upgrade.

If you anticipate any upcoming needs for bulk recalls, we will be happy to work with you in advance of March 30th to complete them.

This weekend during the regular maintenance window (Saturday morning 3 am to 6 am), we will be applying the monthly Microsoft updates to the New Orleans campus Email and the LSU Health FileS servers.  Below are the affected servers and expected downtimes.

  • Exchange 2010 Mailbox servers (N.O.) – about 1 minute of total downtime as mailbox databases are switched over to alternate servers and back
  • Exchange 2013 Multirole servers (Enterprise) – no anticipated downtime as all current roles are redundant
  • LSU Health FileS server (Enterprise) – about 10 minutes downtime during which users will be unable to send or retrieve attachments
  • Lanfear server (Enterprise) – about 10 minutes downtime during which Listserv services will be unavailable.

In order to remain supported by the vendor, the “File System Archiving” software that is used on all home shares and department shares that are hosted by LSUHSC must be upgraded.    This process will begin Tuesday, March 14th, at 5:00 pm and is expected to require about 4 hours of downtime.   During the maintenance, it will not be possible to recall individual files from the archive, or to process requests for “bulk recalls” of all files within a particular folder tree.    As a reminder, you can identify which (if any) of your files have been archived, by way of the gray-colored “X” found in the lower left of the file icon.

By design, the only files that have ever been eligible to be archived are those files that no one has accessed in at least 6 months, so any files that you have viewed or modified in the recent past should remain accessible throughout this maintenance.    Only those files that have not been accessed in more than 6 months, and then were archived, will become unavailable for the duration of the maintenance.

Once the maintenance has completed, you will again be able to retrieve individual archived files simply by double-clicking their icons, without any need to take any additional steps on your workstation.

If you anticipate any upcoming needs for bulk recalls, we will be happy to work with you in advance of March 14th to complete them.  Contact the help desk at helpdesk@lsuhsc.edu or 504-568-4357.
