Microsoft Investigating Multiple Windows 11 Issues

While some of the issues are not fatal, others like a memory leak in File Manager that can only be recovered from by rebooting are more of a problem. I recommend waiting for a month or two in order for other users to detect more bugs. Credit: Bleeping Computer

Feds Arrest Nuke Navy Engineer for Selling Nuke Secrets to Foreign Power

A Navy nuclear engineer stole restricted data for a Virginia class nuclear submarine and tried to sell it to a foreign power. For whatever reason, the person that he contacted in the unnamed country shared his letter with the FBI. They strung him along for a while as he made several dead drops of data and they paid him cryptocurrency until they arrested him last week. He was able to smuggle the documents out past security, which just shows how hard it is to actually secure against a determined adversary. Credit: The Register

An unintended Consequence of Covid Vaccine Passports

The UK is one place where vaccine passports are required. The app that runs on people’s phones is managed by the National Health Service or NHS. The app has a barcode that security at the airport can use to check a passenger’s vaccine status. No proof of vaccine or negative Covid test and you can’t get on that plane. Which is great until the app’s backend database crashes like it did today. For about 4 hours. Heathrow came to a standstill. One journalist reported that she was offered a later flight for a 250 Pound fee. Oh, yeah, and she would need to take and pay for a rapid Covid test for another 119 Pounds. She opted not to fly. Another passenger tried using his paper vaccine card, but security would not accept it. The app has an offline mode or you could screenshot the barcode, but those only work if the app is running. Unintended consequences. Credit: BBC

Treasury Links $5 Billion in Bitcoin to Ransomware

The U.S. Treasury’s Financial Crimes Enforcement Network (FinCEN) has done some trolling on the Bitcoin blockchain. Anyone who thinks that bitcoin is anonymous does not understand how that works. They identified Bitcoin wallet addresses after analyzing suspicious activity reports (SARs) that banks send in. This has nothing to do with actually recovering any money. If they put those wallets on the banned list then the hackers will create new wallets (which they should be doing anyway to make things harder to track). It is probably a good thing for them to do because a lot of crooks are stupid and those are the ones that they might catch out of this. Credit: Bleeping Computer

Fallout From the Epik Hack

Epik, as I reported earlier, is a domain registrar that is kind of a last resort for people who can’t get another registrar to manage their domain – along with many vanilla domains. Epik supports a number of conspiracy theory and alt-right domains because they say that they are neutral in the battle. As a result of being hacked, a lot of data which people would like to remain private became public. As a result of that, people are being fired and businesses are losing customers. One person, who’s information was disclosed, continued the conspiracy theory tactic and said that the data was easily falsiable (who did this – Epik or the hackers – and why?), that he was the possible victim of extortion and the newspaper that reported the information was “fake news”. Possible, but that is likely not going to help some people who get outed. Credit: The Washington Post

Remember When Microsoft Said Windows 10 Was the Last Version? Just Kidding!

Microsoft did learn something from Windows 10 – don’t mess with their cash cow. They will continue to work on Windows 10 for the enterprise with a new release in the fall and cumulative updates for years.

But for consumers eager for the next new shiny object – Windows 11, here we come. For early adopters, it will be available on the ‘dev’ channel next week with a release in the fall.

I am not sure if Microsoft has run out of things to do with Windows, but they are touting Win 11 features like rounded corners, colorful icons, new animations and UI controls. With new features like that, you can see why enterprises are likely to stick with Windows 10.

Of course, improving stability, memory management and task scheduling are not sexy – but very important to the enterprise. Getting rid of that 25 year old code that is still in Windows – nah!

I don’t know; maybe I will become a believer after I see it, but so far, I am not impressed.

It seems like they are tweaking at the margins. Some new features include:

In addition to the user interface refresh, Windows 11 also introduces many new features, including a redesigned floating and centered Start Menu, a revamped windows snapping feature called Snap Groups, a new and improved Windows Clipboard, modern disk management, redesigned settings screen, and much more.

Finally, they ARE killing off some of that 25 year old code. Companies that still run apps that require Internet Explorer will NOT be able to run Windows 11 except with Edge compatibility mode. Given that IE is a hacker’s delight, removing that is good.

Windows 11’s file explorer boasts rounded corners and new icons, but will it crash less? They aren’t saying.

They are finally adding a way to manage your webcam without having to install third party apps. That is nice.

They are also adding support for DNS over HTTPS, a nice security feature.

Now here is an interesting feature. Apparently, Windows 11 will have an Android emulator* so that you can run any Android app (no, not iPhone apps, Apple probably would get upset if they did that). That means all sorts of games and productivity apps that people run on their phones will run on your PC too.

* The emulator is really not an emulator but a post compiler that allows apps to run natively . If this is true, that means that app performance should be good.

Some things will be going away in Windows 11, although you may be able to load them from the app store if you insist, including:

IE, Timeline, Tablet mode, Wallet, 3d viewer Paint 3D, One Note, Skype, Cortana, Windows 10 S mode and others.

Not going to miss any of these.

Why The Microsoft Exchange Email Hack is So Bad

The media continues to report on the Microsoft Exchange hack, likely perpetrated by China. Reports are that at least 30,000 Exchange servers in the United States are impacted and some people say that number is likely way underestimated. On top of that, the number of servers worldwide is maybe ten times that number.

Given all the media attention, you would think that everyone would, at least, install the patches. It appears that AT LEAST 46,000 servers are not patched, according to The Record.

So why is this a big deal? First, the attackers could read any email on those servers. Whatever that might contain. One organization affected was the European Banking Authority. They say that no data was accessed. Sure, we believe them.

Second, the attackers, in many cases, left behind a present called a web shell. It is a way for the attackers to get back in to the server later. Many of our IT partners decided the only way to make sure that the hackers are really out is by rebuilding the servers from bare metal, not a simple task, especially if you have to do that to tens of thousands of servers.

So lets look at the timeline involved. We are getting more details every day and this timeline is interesting. This timeline comes from Brian Krebs, who Chris Krebs, former head of DHS CISA called his brother from another brother (i.e. they are not related).

Security testing firm Devcore says they alerted Microsoft on January 5 – two months ago.

On January 6th, Veloxity spots attacks that use unknown Exchange bugs

On January 8th, Devcore told Microsoft that they had been able to reproduce the bug.

On January 27th Dubex tells microsoft about new attacks on Exchange servers.

On January 29th, Trend Micro reports in their blog about these web shells infecting Exchange servers, but incorrectly says this was allowed by a bug patched last year.

In February, Microsoft tells the folks who reported the bug that they had escalated the problem and that they had a target release date of March’s patch Tuesday, March 9th.

By the end of February, the cat is out of the bag (it is hard to keep good news secret) and security folks are seeing global mass scans of Exchange servers looking for vulnerable systems.

This forces Microsoft’s hand and they released the patches a week before they planned to, now on March 2.

By March 3rd, tens of thousands of Exchange servers have been compromised. Once the patch is out, especially knowing that it is an emergency patch, hackers worldwide reverse engineer the patch, likely within hours of it being released.

By this time it is a national security emergency and everyone from CISA (who told government agencies that they had 48 hours to patch their servers or shut them down) to the White House to the National Security Advisors are sounding the alarm bell.

On March 5th, Chris Krebs, former head of DHS CISA says that the real number of compromised servers dwarfs the numbers being reported.

Needless to say, this is a big problem.

A couple of interesting footnotes.

Microsoft says that Office 365 was not compromised. Why? Don’t know. Possibly their server configuration is different. Possibly, since they knew about the bugs in early January, they were able to tweak their security before the word got out. I vote for number 2. Apparently at this point, now that we know how the attacks work, it is easy to block new attacks.

Second, Microsoft released patches for every supported version of Exchange. That means that the bug goes back, at least, to 2013.

But wait. Microsoft even patched an unsupported version of Exchange – Exchange 2010. That means that the bugs go back at least a decade. Possibly more.

Now here is the answer that we don’t have.

Were these bugs being quietly exploited for years? Remember if you do it quietly, you probably won’t get noticed.

If so, by whom?



Private hackers?

The NSA, CIA, Others?

Foreign intelligence agencies – friendly or not?

And if so, what have they stolen?

Likely we will never know the full extent of the attack, but between the SolarWinds hack and the Microsoft Exchange attack, one thing should be clear. We came to a gun fight with a spoon. And if we do not improve on our security efforts, we are going to continue to lose.

Happy New Year. May 2021 be more sane than 2020.

Microsoft Says Goal of Solar Winds Attack Was Your Cloud Data

Microsoft says that the objective of the Solar Winds Hackers was to get into a number of organizations and then pick and choose which ones to attack, leaving the back door in place at the others for future operations. One way to do that was to generate SAML login tokens from inside the network and then use those tokens to gain access to cloud resources, including, but not limited to email. The article also provides more information on how to detect if the hackers did compromise your cloud resources. Credit: Bleeping Computer

“Swatting” Moves to the Next Level

Swatting, the practice of calling in a fake 911 call so that SWAT teams are deployed to the victim’s location based on, say, a fake kidnapping, are moving to the next level. As if having the police show up unexpected with lots of guns and breaking down your door isn’t bad enough, now the perpetrators are taking advantage of the fact that people choose crappy passwords and are watching and listening to the police assault on the victim’s own smart devices. On occasion, the situation becomes deadly when the police, not really knowing what to believe, shoot the victim. On rare occasions, the swatters, as they are called, are caught and prosecuted.

I Think The Wasabi Got a Little Too Hot

Wasabi, the cloud storage competitor to Amazon S3 that claims that it is significantly cheaper than Amazon and 99.999999999% reliable just got a little less reliable. Their domain registrar notified them of some malware hosted on one of their domains. Only they sent the email to the wrong email address. The registrar, following normal procedures, suspended their domain for not responding to an email they never got, knocking many of their customers offline.

After Wasabi discovered they had been DDoSed by their domain registrar, they suspended the offending customer and asked to get their domain back. That process took over 13 hours. Are you ready for this kind of attack from your suppliers?

That attack probably knocked several of those 9’s off their reliability, depending on how the mess with the data.

Solar Winds Troubles Are Not Over

A second piece of malware called SUPERNOVA and a zero-day vulnerability that it exploited makes it look like there may have been a second attack against Solar Winds. This appears to be a separate attack from the Russian attack. The attack vector is different too – this is not an attack against Solar Winds code base. This spells additional trouble for Solar Winds.

Remember That Vague Client Alert Earlier This Week?

For those of you who are clients, you received an out of cycle client alert on Tuesday (they usually come out on Wednesday) providing a copy of the Homeland Security Alert on the Sodinokibi ransomware going after Managed Service Providers or MSPs.   It now appears that the attack on Texas towns (see below) is based on an attack on the MSP hosting the systems of those municipalities.  Assuming that is true (The state of Texas is being very vague on the whole situation), that could explain why DHS issued the alert at this time.  To reiterate the recommendation in the alert – make sure that your MSPs’ security programs are up to the task.  In the case of Texas, one town has announced that the attacker wants that town to pay $2.5 million in ransom.  Source: Bleeping Computer.

20 Texas Towns Hit by Ransomware.  Wait 23.  Wait …..

Cities and towns across the country have been hit by a wave of ransomware attacks, but of course, everything is bigger in TEXAS.

While the press release is very short on details, the Governor has called out the Texas Military Department (that is the combination of the Army National Guard, the Air National Guard and the Texas State Guard, which is an organized militia as defined in the Constitution) along with the experts at Texas A&M University (The Aggies have a world class cybersecurity capability) to help the cities impacted deal with the situation.  While Colorado was the first state to activate the National Guard to help with a cyber attack, Texas is now the third (after Louisiana) in what may become a trend.

IRS Notifies Thousands of Cryptocurrency Traders of Back Taxes and Penalties

Not wanting to leave money – even digital money – on the table, the IRS has sent out letters to thousands of cryptocurrency traders who did not report the trades on their tax returns assessing them  taxes and penalties along with the threat of possible criminal prosecution.  Not a big surprise, but if you thought you could escape the tax man…  Of course, if you are trading peer to peer, then it is 100% unlikely that the tax man will ever find you.  Source: CNBC.


Huawei Goes Into Full Battle Mode

Huawei CEO Ren Zhengfei sent a memo to the company that says, in light of the US bans, that it was time for the company to go into full battle mode, making references to the military bible, The Art of War.

As President Trump effectively admitted, the ban on Huawei has only a little to do with national security and all to do with his trade war, by continuing to suspend the ban – which is affecting US companies bottom lines and user’s security.

In the mean time, Huawei says that it will build 60,000 5G base stations this year and 1.5 million next year – all without any US components.  Since other countries continue to buy Huawei equipment and US rural cell carriers say that that it will cost them more than a billion dollars to replace Huawei equipment which they do not have – meaning that they will dramatically slow 5G deployments.

Currently the US is lagging in 5G deployment and despite the President’s wishes that this is not so, this is not likely to change any time soon.  Read the details of this dance here.


Plan for End of Life of Software Support

End-of-life in software and hardware means no more security fixes and given the number of fixes we see every month, using software and hardware that is no longer supported is not a good plan.  No more patches does not mean no more flaws – just no more fixes for those flaws.  Hackers count on that fact.  Here is what is coming up to the end of life soon:

Python 2 on January 1, 2020 (about 4 months)

Windows 7 on January 14, 2020 (also about 4 months)

Windows Server 2008 and 2008 R2 also on January 14, 2020 (4 months).  As an incentive to get you to migrate to Azure, if you migrate your Windows 2008 servers to Azure before January 14th (and therefore pay Microsoft monthly cash), they will support Server 2008/2008 R2 for three more years.

For states with cybersecurity and privacy laws that say that you have to take reasonable measures to protect your data, it will be hard to defend in court, if you have to, that using unsupported software is taking reasonable measures.

Google to Add GMail Features – Maybe – For A Fee?

Google has a interesting strategy.  Build prototypes of products.  Show them or leak them.  See if anyone cares.   Kill them if it doesn’t work out – there are lots of examples.  After many users are already using them.

One other thing that they do is attempt to lock users into the Google ecosystem.  Of course.

Tech Crunch is reporting that Google is working on a self destructing email (like Snap Chat for email?).  But it only works if both users are on GMail and only if both users use the web client for GMail.  Sounds a bit limiting.  If one user is not using the GMail web client, they get a link instead that takes them to the web.

They may also be adding a feature to stop printing and stop forwarding.

Again, if they do, it will only work for GMail on both ends and only with the GMail web client.

Information for this post came from The Register.

So what does this mean?

Well first, what seems to be missing is end to end encryption, which seems like a pretty important feature.  

But encryption stops them from reading your email and doing things that they like to do.  They don’t read your emails to target ads – they have better ways to target ads – but they do read them for other features.

Next, the speculation is that this will only be available under the paid GMail model (GMail for business).  The paid version costs either $10 or $25 a month per user.  At that price there are competitors.

As of last year, Google said that they had 3 million paying users.  Microsoft says that they have 60 million paying Office 365 users and adding 50,000 customers (not mailboxes) a month.  Google never wants to play second fiddle.

It is certainly possible that they will give it away for free, but given that they are so far behind Microsoft, maybe not.  With GDPR taking effect in the European Union next month and other countries, not including the U.S. following the EU lead, maybe ad revenue might be less predictable going forward.  Millions of monthly paying customers might be nice.

If you are looking for a free answer for secure email, Proton mail is a good choice.  They also have a paid version with more features, but the free version is pretty good.

Office 365 has nice security features at well below $25 a month.  Microsoft has said that they are about to roll out end to end encryption for all paid Office 365 users at all levels.

The bottom line is that if you are looking for a secure email solution there are some decisions to make.  To me, Google’s solution is not so great.
