Microsoft confirms that "WannaCrypt" uses an NSA exploit

That's some nasty business man. Made sure all my stuff was up to date after reading about that this morning.
 
It technically uses two exploits that had been held by the NSA a while ago before they got hacked. The way it spread (NSA's nickname for it is 'EternalBlue') only worked if the target machine hadn't had March's patches installed. If it detects it, it will also make use of the other ex-NSA exploit, codename 'DOUBLEPULSAR' if that hasn't already been disabled as well.

Sadly our Governments will always keep any exploit they find hidden as they won't be affected by this.
 
Linux is the solution. I am not well informed on this subject so i will ask. Why aren't hospitals, and businesses using Linux instead of Windows? It is rock solid, and free.

Sigh....simple answer in my opinion? Because nurses/doctors/secretaries/etc simply WONT learn the new system. Now, one could install a version of linux that looks and acts significantly like windows (its out there can't recall the name) and that would work wonderfully.

Longer answer? Governments / faculties / schools / medical buildings / don't have the time or money to do retraining on employees on how the new OS would operate. Never mind the fact that these same places ONLY use it for typing documents / patient information / google things / etc...nothing super intensive or 'power user' type things.

So there is no reason these places shouldn't be using either mac OSX or a version of Linux, it's just the fact that they don't care because everything in government takes forever and a year to get going. That would be the biggest reason why (again my opinion is all) because lets all face it, as far as exploiting is concerned windows is the most targeted OS. Sure you CAN target Macs or Linux distros....but no one does. Why? its harder, more time consuming, often enough not enough to gain quickly and easily, and generally you could probably have 3-5 windows machines compromised before 1 linux/mac machine. So again, time and effort vs reward chances....reward chances win everytime so windows will continue to be targeted over the other OSes.


This is all just my two cents is all, take it for what it is.
 
Over the weekend i was in contact with a couple of IT project managers who work for the NHS who have been pretty badly effected by 'wannacrypt'. They just were not prepared for any attack of this kind and are looking at weeks and possibly months of recovery time.

Most companies just dont want to spend the money on patching systems and are often 6 months or longer behind on critical microsoft patching of vulnerabilities.

Linux like all other OS's is vulnerable to exploits and there have been a lot of high profile potential exploits that havent been utilized. Hospitals dont use linux because a lot of the mission critical software they use is coded in windows only. There is also the training element which is cost prohibitive to most organizations.

Its scary that we are living in a time where the security services are stockpiling vulnerabilities and buying a lot of vulnerabilities from very questionable sources.

Good to see you back:)

Linux is only "rock solid" because so few people use it. The same with apple. If the usage numbers were switched with Linux being at the top and Windows at the bottom then Linux would be were Windows is. Completely insecure and riddled with Virus'.

Why code something that will infect 100 people when you can spend the same amount of time coding that will effect 1 million people.

Also, going to Linux really is not up to the hospitals.
Back when they were starting to use computers Linux was not a real option. Windows was their only option. So when they started buying other machines (MRI's, blood testers, bespoke software....) it was all coded for XP only.
To move all of that software over you'll have to pay each and every company to remake each piece of software then pay for the licence for each system.
It would take many years and billions of £'s.
 
Yeah corporate applications and specialized software are pretty much all windowscentric for a large corporation and the developments costs are prohibitive.

Also as mentioned above there are not enough end users to be worth specifically attacking Linux.
90% of my day is in a corporate app and 10% typing documents and other stuff (and a few% OC3D)
