Just a quick note with some good information on the newest Malware threat to be in the news.

Some background information on the whole story (if you haven’t heard of it) can be found here, there and also over here.

Aaron Silber sent over some useful links to test if you have been infected and some instructions on removing it if you have been compromised.  Be sure to test all installed browsers on your machine.

Microsoft updated Windows Defender to catch the malware and remove it.

Lock-Blocked by vSphere Lockdown mode.

I was doing some routine upgrades this past night when I ran into a strange issue that I figured I would make a note of.  While using VMware’s Update Manager to upgrade an ESXi host from 5.1 to 5.5, I ended up getting a pretty cryptic error message from Update Manager letting me know I couldn’t proceed.

The details complained about not having enough memory to create a scratch space partition to store the upgrade image.  Weird.  My host had plenty of free space on the drive and tons of memory – All the VMs were evacuated and I had all the host memory to myself.

Fast forward after a bit of Googling and I ran across this blog post.  The alert message was exact but the resolution wasn’t correct for my situation.  Luckily someone had posted another resolution in the comments. (Side Note: Even if you don’t have the time or desire to run a blog, just adding comments to existing blog posts is a great way to contribute back to the virtualization community.)

The hosts I was working on were in a DMZ and had Lockdown Mode enabled.  The commenter had mentioned disabling Lockdown mode as the answer.  Worth trying!

I made the quick modification in vCenter to the DMZ host, reran the Update Scan and successfully upgraded the host to 5.5.  Just had to remember to re-enable lockdown mode after the reboot.  Lockdown mode only affected the actual upgrade and not the patches.  Patching a lockdown host presented no issues at all.

PSA: Watch out for CryptoLocker / CryptoWall emails

With the holiday season here, your users will be getting plenty of packages and tracking emails.  They will also be getting more than their share of malware infested scam emails.  Be a good IT Admin and remind them that vendors do not send attachments with tracking information inside for them to click. 

Curious where your package is?  Visit FedEx, UPS or USPS websites directly.  Or better yet, just paste your tracking number right into Google.

We’ve had a few clients recently where some gullible users have clicked through on these attachments and were hit with encrypted files and ransom notes.  Keeping your antivirus and anti-malware DAT files up to date is a great start but a little education and subtle reminders to the user community will provide a good last defense.

Happy Virus Free Holidays! :)

IPM Sponsored - Upcoming VDI Rollout Webinar

A few months back, I helped Phil Alberta (CIO at IPM) with a great onsite VDI workshop called VDI Myths.  It was focused for the hedge fund crowd, hosted at Goldman Sachs and was well received by the audience.   For me, it was also a lot of fun to participate in.   You can read about the details here.
(http://www.vmwareinfo.com/2014/07/some-vdi-myths-and-pdf.html)

This time, Phil is teaming up with Jim Kannengieser (Program Manager at IPM) for a webinar titled ‘Make your VDI Project Shine’.  With their varied experience, they will talk about how to get the most out of your VDI investment.  This particular talk will be Citrix focused.

The webinar is Thursday December 18th @ 1pm EST so grab a cup of coffee or sandwich and tune in for 30 minutes.  Be sure to register for the event here and get a handy Outlook appointment so you don’t forget. ;)
