Trouble with Microsoft update KB3161608 for Windows 7 and Server 2008
Posted by Rubin Bennett on 27 June 2016 09:57 AM

Hi folks

We've had a handful of reports of issues with a recent patch (released last week).  It's a Windows 7 and Windows Server 2008 "optional" rollup that includes among other things a fix for the Poodle vulnerability. It's causing issues with Outlook when used with certain mail server software and has also caused issues with credit card processing software.  Removing a patch for a known vulnerability is usually a Bad Idea and we tend to be very reluctant to do it.  However, there have been a handful of sites where the business impact of the update created a critical stoppage, and removing the update was warranted as a temporary fix as we work with outside vendors to update their TLS and SSL handling routines.

If you're experiencing issues like the ones described above, please contact the team.  If you're under our Perception managed services program, we can automatically remove and decline that patch from all of your systems in a matter of minutes, and functionality will be restored.

If you have any questions, please get in touch!

"Locky" Virus making the rounds
Posted by Rubin Bennett on 18 March 2016 10:01 AM

It's a new year, and there's a new virus that's making the rounds.

If you receive email, often purporting to be from yourself or someone within your company, that contain invoices as either attachments (usually .zip files) or links to a dropbox URL, be very suspicious. The 'Locky' virus is an relatively new variant of the Cryptolocker, and it encrypts your data using non-reversible ciphers. It encrypts local data and also data that you have shortcuts to on shared folders on the network. Once the files are encrypted, the only recourse is to restore them from a backup once the infected computer is cleaned up.


We're seeing a significant uptick in the number of infections, and awareness is  the most important way to prevent yourself from becoming the next victim. Infections are easy to prevent by using proper email etiquette and being cautious about any messages you receive that contain .zip files or links to websites.


If you have any questions, comments, or concerns, please don't hesitate to contact
your tech team here at the office!Thanks as always for making rbTech your trusted I.T. provider!

Sincerely,

Some of you may have seen the hair tearing announcements over the weekend or late last week about the 'most epic vulnerability' in Linux, ever (https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2015-8370).

While we fully understand the seriousness of the vulnerability (after all, pretty much anyone can hit backspace 28 times, which is the trigger for the bug), we also work hard to balance the risk of a vulnerability with the real world implications.  In order to exploit the vulnerability, an attacker must have physical access to a Linux server, at the console.  For physical servers this means being at the console.  For virtual machines, that means taking control of the host before you can access the console.  What this vulnerability really does is serve as a reminder, again, that physical security is important.  We've said it before, and we'll say it again:  If an attacker has physical access to your servers, all bets are off.  It doesn't take a talented attacker to boot your system up from a USB drive and have their way with it.

All that said, be asured that we'll be in touch soon to apply updates to your vulnerable systems!  As always please let us know if you have questions, comments, or concerns!

P.S.:  To put this particular vulnerability into perspective, if you have console access to a Linux system with the Grub or LILO (old) bootloader, you can simply boot it with the 'single' command appended to the boot string, and the system will boot into single user mode and drop you to a root prompt.  In rare instances, single user mode will prompt you for a password, but on many if not most systems that setting is not configured.  Which is to say that the new security issue is not that much worse than the existing state of things as they've been by design and default for years and years.

What you should know about Windows 10
Posted by Rubin Bennett on 06 October 2015 08:30 AM

You've seen the icon on your desktop asking you if you want to upgrade.  You've hovered your mouse over it, poised to click OK.  But then that little voice in your head told you that may not be the best plan ever, and you moved your mouse away, and went back to work.  You thought, maybe you should check with someone before you click that ever-present little slice of temptation in the system notification area.

But who should you check with?  Who would know how Windows 10 is going to affect your systems?  Your trusty I.T. company, of course!  We've seen it all - the good, bad and ugly parts of the Windows 10 upgrade, and what it can mean for you.  Some of us are running Windows 10 here at the office, and we have a number of clients who have upgraded some of their systems as well.  Some have gone smoothly, others have run into issues with their line of business software or run into other incompatibilities.

But maybe you're one of our managed services customers, and you haven't seen the notification icon.  Maybe you're feeling a little left out, because we immediately decline all Windows 10 upgrade notifications, and only approve them for customers by request.  Have no fear, you can have some Windows 10 too.

If you're curious about all the hype and are considering upgrading to Win10, give us a call and we'll give you honest, real world pros and cons.

Happy computing!

ReSOURCE Essential Goods Program
rbTech is collecting usable workstations, laptops and servers that you may no longer need or want, to give to ReSOURCE's Essential Goods Program.  These computers are re-purposed and have updated Windows operating systems installed on them. Computers are then sold at very reasonable prices to folks who may not be able to afford the cost of a brand new computer.  The program creates job training, employment opportunities and gives new life to gear that would otherwise be recycled for scrap.  Check out their website for more information on  great community partner ReSOURCE
 
E-waste Recycling
rbTechnologies is a responsible e-waste recycling partner. Computer hardware and other electronics that are not in usable condition will be sent to Good Point for proper recycling.  For questions about what types of electronics that can be recycled, please contact Operations Director Steve Gilman at 223-4448 x102.
 
We hope to see you here at rbTechnologies Friday July 24 from 1:00-4:00 rain or shine for our 18th birthday party, customer appreciation open house and free electronics recycling event.
