Microsoft email zero day
What is it? Microsoft is investigating targeted attacks on their on premises Email servers. Attackers have found a way into servers that are already fully patched.
If we have online email with Microsoft, are we at risk? No.
Is this disturbing that EVERY time there is a zero day in Microsoft on premises email servers, Microsoft can conveniently scramble and get their online servers patched and meanwhile those that purchase on premises software are stuck holding the bag.
If you are an Exchange admin and need help, pile on here
(note I am sending this out as a defcon text alert but not an email alert)
Follow the guidance in the MSRC post to protect your on premise email servers:
The current mitigation is to add a blocking rule in “IIS Manager -> Default Web Site -> URL Rewrite -> Actions” to block the known attack patterns
Note:
If you don’t run Microsoft Exchange on premise, and don’t have Outlook Web App facing the internet, you are not impacted.

MS-DEFCON 2: Printing issues, again
ISSUE 19.31.1 • 2022-08-04 By Susan Bradley
This time we’re forewarned, and the problem probably won’t affect many.
Here we go again. Month after month this year, updates have affected printing in some way, and the side effects have ranged from minor to major (such as printers being completely disabled).
Fasten your seatbelts anyway, although chances are that many of us won’t notice this side effect at all. In fact, the security fix causing this side effect has actually been installed on our systems for over a year. Starting with the July and August updates, “hardening” is finally being enabled. Still, prudence demands raising the MS-DEFCON level to 2.

MS-DEFCON 4: July updates make some hot and bothered
ISSUE 19.30.1 • 2022-07-26 By Susan Bradley
Access bugs ruin a quiet July, but we can still lower MS-DEFCON to 4.
To any reader of this alert who is sweltering in a heat wave, my sincere condolences. I can slightly relate, as I’m having the normal July heat wave in my neck of the woods.
The big difference is that my area of the country is used to this weather. Thus I’m inside an air-conditioned home, remotely accessing office workstations and servers to perform the monthly maintenance tasks while some of you are … well … just really hot and really uncomfortable. Fortunately for us, this month’s Windows and Office updates were mostly well behaved.

MS-DEFCON 2: Pause to review
ISSUE 19.27.1 • 2022-07-07 By Susan Bradley
We’re halfway through the patching year.
It seems like just yesterday when I lowered the MS-DEFCON level to allow a cautious breather so we could apply critical patches. Oh, wait — that’s right, it was just last week.
In June, Patch Tuesday fell on the latest day of the month possible: the 14th. It takes all of us patch watchers a little bit of time to assess the safety of the last round of updates — and before you know it, the next Tuesday is upon us. So after little more than a week, it’s time to pause updates again. Accordingly, I am raising the MS-DEFCON level to 2.

MS-DEFCON 2: Zero days unpatched
ISSUE 19.23.1 • 2022-06-09 By Susan Bradley
Once again, we are faced with several zero days that are plaguing Office and Windows.
Accordingly, I am raising the MS-DEFCON alert level to 2.
At this time, the vulnerabilities are being used in targeted attacks and ones that are more probing in nature (probes test the ability of the attack to get in but don’t take action). So far, we have not seen widespread attacks, but there are some ways you can proactively protect yourself.

MS-DEFCON 2: 2004 is out of support
ISSUE 19.18.1 • 2022-05-05 By Susan Bradley
Check your Windows version, then update accordingly.
I regularly come across PCs that are running old, out-of-support versions of Windows because they aren’t on the Web long enough to be “serviced” by Windows Update. For example, there are two Surface laptops in my office that are used by people on cellular connections. As a result of sporadic use, they never get a feature update.
Just the other day, I realized they were running Windows 10 2004 and thus no longer were getting security updates, a serious matter.

MS-DEFCON 2: Deferring April
ISSUE 19.14.2 • 2022-04-07 By Susan Bradley
Don’t let April showers rain on your PCs.
I love April. It’s the end of the busy tax season at the office, and it’s spring where I live — the tulips are in bloom. But what I don’t love is updates disrupting my business before the end of the busy season. So I urge you to do what I do at the office: defer those updates.

MS-DEFCON 5: A very quiet February
ISSUE 19.08.1 • 2022-02-22 By Susan Bradley
For the first time in an extremely long time, this month of patching has been so quiet that I’m changing the patching status to the magical level of 5.
All’s clear. Patch while it’s safe!
Don’t blink, because it may not happen again. There are so few issues that it feels too quiet, like the calm before the storm. The only thing I’m tracking is a few reports on issues with the 2012 R2 print server, because it broke printing on DataMax label and badge printers. However, I’m not tracking any issues with standalone printers.
