Wana Decryptor Ransomware Using NSA Exploit Leaked By Shadow Brokers To Spread Ransomware Worldwide (threatpost.com)

msm1267 quotes a report from Threatpost: A ransomware attack running rampant through Europe today is spreading via an exploit leaked in the most recent Shadow Brokers dump. Researchers said the attackers behind today's outbreak of WannaCry ransomware are using EternalBlue, an exploit made public by the mysterious group in possession of offensive hacking tools allegedly developed by the NSA. Most of the attacks are concentrated in Russia, but machines in 74 countries have been infected; researchers at Kaspersky Lab said they've recorded more than 45,000 infections so far on their sensors, and expect that number to climb. Sixteen National Health Service (NHS) organizations in the U.K., several large telecommunications companies and utilities in Spain, and other business throughout Europe have been infected. Critical services are being interrupted at hospitals across England, and in other locations, businesses are shutting down IT systems. An anonymous Slashdot reader adds: Ransomware scum are using an SMB exploit leaked by the Shadow Brokers last month to fuel a massive ransomware outbreak that exploded online today, making victims all over the world in huge numbers. The ransomware's name is Wana Decrypt0r, but is also referenced online under various names, such as WannaCry, WannaCrypt0r, WannaCrypt, or WCry. The ransomware is using the ETERNALBLUE exploit, which uses a vulnerability in the SMBv1 protocol to infect vulnerable computers left exposed online. Microsoft issued a patch for this vulnerability last March, but there are already 36,000 Wana Decrypt0r victims all over the globe, due to the fact they failed to install it. Until now, the ransomware has laid waste to many Spanish companies, healthcare organizations in the UK, Chinese universities, and Russian government agencies. According to security researchers, the scale of this ransomware outbreak is massive and never-before-seen.
UPDATE: The Guardian reports that "An 'accidental hero' has halted the global spread of the WannaCry ransomware" by discovering a kill switch involving "a very long nonsensical domain name that the malware makes a request to." By registering that domain, the spread of the ransomware was effectively halted.

      No. Say thanks to Micro$oft for making people extremely gunshy after their concerted efforts to force Windows 10 down everyone's throats.

      It's bad enough to worry that an update to a bad driver will brick your machine without the problem of waking up to find Windows 10 on your machine.

      I'm sure there's enough blame to go around here, but don't forget that the update paranoia around Windows OS's was brought to you by none other than Micro$oft themselves.

      Blame lax IT policies and ineffective management for leaving exposed machines to the internet unmatched. Of course your going to get hosed. Most know to put a firewall, enable the machine's firewall, or air-gap their systems.

      Since there were so many people that turned off updates to avoid getting MS Windows 10 unasked I don't think blaming the victims is a useful approach.

    I've said it before but it bears repeating.

    When you create an exploit, you create a weapon but when you submit a fix, you make that weapon ineffective. So now instead of having the world's best armor, we have an absurd cache of weapons and those weapons have been stolen. The moral isn't to protect your weapons better, it's that you should be making better armor.

    You got it all wrong. The entity to blame is Microsoft. Their operating system is poorly secured which is the root cause of this entire mess.

    And you use unpatched computers in a hospital WHY?

    Because patches are often broken. Imagine these hospitals had applied the patch when Microsoft released it, but the patch was faulty in some way, and all of the hospital computers went down as a result. Instead of complaining the hospitals were running unpatched, you and/or many people like you would be bitching and moaning that they were negligent to install the patch too soon.

    Updates from Microsoft frequently include at least one broken patch. There was one update last year that broke millions of peoples' webcams. There have been several updates that interfered with settings and reverted them back to default configurations, and several more updates that seemingly deleted group policy objects that had been configured by the domain administrator. There was a patch around the new year that inadvertently disabled the DHCP service, despite the update itself having nothing to do with DHCP. (Things that make you go hmmm.) This particular fuck-up rendered a lot of machines not only broken, but totally irreparable without manual human intervention, i.e. dispatching someone clueful to each of your premises to clean up the mess.

    Patch deployment in any enterprise environment requires extensive testing. You have to coordinate with your software vendors to make sure their applications are compatible with the update. If you install Patch XYZ without first getting approval from Vendor123, you wind up invalidating your support contracts with them. All of this takes time. In 2016, there were several months in a row where Microsoft had to un-issue, repair, supersede, and re-release a broken patch they'd pushed out. Put yourself in the shoes of an admin team who got burned by Windows Update breaking your systems, especially repeatedly. Are you going to be in any hurry to patch? If you were bitten by the DHCP bug, do you trust that the "critical SMB patch" really only touches SMBv1, and isn't going to inexplicably corrupt Office or remove IPV4 connectivity on every computer it touches?

    If the PC your kid plays Minecraft on gets hosed by a broken patch, it's not that big of a deal. The business world is a different story.

    Microsoft told lie after lie after lie about their intentions. There was absolutely no reason to believe that setting your update threshold to "Critical Only" would save you from an unsolicited Windows 10 installation.

    The only rational course of action for those who didn't want Windows 10 was to turn off Windows Update entirely. Deny this all you want, but be prepared for justified accusations of victim-blaming.

    common sense tends to get driven out by a business MBA who is an expert in efficiency.

    proprietary software created by a vendor that is 4 guys in an office somewhere on the other side of the planet, who just got bought out by megacorp which then spun off as dildicorp and fired all the original creators... does not have a flying clue about why your Blobnatz75 driver doesn't work on Windows 10, nor are they going to get an answer anytime soon.
