Friday's ransomware outbreak is ongoing, and while researchers work to stem the tide of infection, businesses, governments, and individuals can help the cause by making sure they have protected themselves.

The attack is due to a kind of ransomware called Wanna Decryptor, also known as WannaCrypt, WanaCrypt0r, and WannaCry. The malware not only infects targets through traditional means -- such as phishing campaigns, malicious emails, and dodgy attachments -- but once a system has been infected, the malicious code scans for additional targets through networks and jumps to fresh victims.
When a system has been infected with WannaCrypt, the malware encrypts everything it can -- including the PC's hard drive and any connected devices, such as USB sticks and external storage devices.
The ransomware then locks users out of the system, throws up a landing page, and demands a $300 ransom payment in the virtual currency Bitcoin in return for files to be unlocked. This amount then doubles within a few days if payment is not forthcoming. Users are also threatened with the mass deletion of files within a week if they resist paying.

If you've already been unfortunate enough to become infected with the ransomware, do not give in and pay up. The threat actors behind WannaCrypt have already made roughly $43,000 from the campaign, but there is no guarantee that you will gain your files back if you do.
Instead, unless -- or until -- a decryption key is released by security experts, the best option is to hold tight or restore your system from a backup. Alternatively, businesses can reach out to security professionals to see if infections can be eradicated without damaging their systems.
In order to be protected against this threat, it is necessary to understand that the attack only impacts those running on older Windows operating systems.
A security fix was released in March. It resolved the problem for Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2012 R2, and Windows Server 2016, which are still supported.
If you are running these versions and have not downloaded Microsoft Security Bulletin MS17-010, you should do so now manually, or allow Windows Update to do the work for you.
If Windows Update has been enabled, then automatic updates will be applied. If not, you should re-enable the system and do not disable it again so you receive security fixes as soon as they are available for future threats.
Users of Windows 10 are not affected by the ransomware.
In response to the threat, Microsoft has also released an emergency patch for legacy Windows operating systems, which (as out of cycle products) are no longer supported -- unless special support contracts are in place.
Simple attacks plus user willingness to pay ransoms to get their files back means ransomware is on the rise, warn Kaspersky researchers.
Security updates can be download and deployed manually for Windows Server 2003 SP2 x64, Windows Server 2003 SP2 x86, Windows XP SP2 x64, Windows XP SP3 x86, Windows XP Embedded SP3 x86, Windows 8 x86, and Windows 8 x64 directly from Microsoft.

Microsoft has also added a signature to the Windows Defender antivirus to detect the ransomware.
If it is not possible to patch, as noted by security expert Troy Hunt, you should disable Windows' Server Messenger Block (SMBv1) to prevent WannaCrypt exploit.
Failing this, another alternative is to lock-down machines and prevent them accessing the internet, or at least make sure network settings are as restricted as possible.
What the malware cannot reach, it cannot infect.
This should be a wake-up call for anyone and any business that still relies on antiquated operating systems that haven't been sold in decades. Threats that can cripped a business or destroy irreplaceable, personal content are real -- and security updates, however annoying, are important.
We are yet to see the full extent of how much damage WannaCrypt has caused, and new variants have already been spotted, so if there's any time to update systems and get them to modern OS standards, which are given regular security updates, it is now.

On April 24, I warned everybody that y’all needed to install the March Windows patch MS17-010 right away.
I sure hope you did. Even those among you who never install patches – the Group W contingent.
There’s a huge wave of Ransomware attacks running through Europe, and it’s already been spotted in the US. Britain’s National Health Service and most of its broader healthcare system is on its knees, with medical caregivers greeted by ransomware demands.
The culprit is a ransomware package called “Wanna Cry” that’s using the Shadow Brokers exploit known as EternalBlue to infect — all created by the US’s very own NSA. (Gratuitous comment about tax dollars delete.)
Graham Cluley says:
it would be wrong to think that the NHS was targeted. They weren’t. This plain old extortion – 21st century style. The bad guys release ransomware (in this carried by a worm which exploits a vulnerability), and their intention is to infect as many PCs as possible to make as much cash as possible.
Hitting the NHS wasn’t necessarily their intention, but it is a soft target due to its poor defences. And, of course, the implications of a widespread NHS infection is felt by many people.
If you haven’t installed MS17-010, drop everything and do it. Make a full, clean backup while you’re at it.

UPDATE: Darien Huss reports that
#WannaCry propagation payload contains previously unregistered domain, execution fails now that domain has been sinkholed
Looks like the number of new infections has tapered off.
Nonetheless, get patched, folks.
PLEASE: If you’re going to manually install updates (“Group B” style), you have to keep up with the patching pace. Microsoft released this patch on March 14, without describing its genesis. On April 14, Shadow Brokers released the exploits. By April 24, it became apparent that the EternalBlue exploit was being used to infect normal machines. Prior to that, there was some doubt as to how many machines were infected, and whether the infections were geared toward non-military-grade targets.
Those in Group A were much less likely to get hit because each of the March and April Monthly Rollups had the patch. I gave the go-ahead for March Monthly Rollup on March 30 and the April Monthly Rollup on April 25. If you had applied patches either time, you’d be all clear right now.
If you’re in Group W and don’t install patches — well, now you know one reason why I don’t recommend Group W.
Good technical summary here on Github.
Into conspiracy theories? How about a weapons test that was intentionally disabled with a killswitch before the US woke up? Seems plausible. Cisco’s Talos blog has details.
Or this one, where the worm was released inadvertently by Shadow Brokers and Russian gov.
