Rikkitic:

 

Does Win 10 require patching? I thought it wasn't vulnerable.

 

 

 

 

The exploit code used by WannaCrypt was designed to work only against unpatched Windows 7 and Windows Server 2008 (or earlier OS) systems, so Windows 10 PCs are not affected by this attack.

 

You should install the latest Quality Update for Windows 10.

gzt: What is the initial vector? Word document or executable?

 

We haven’t found evidence of the exact initial entry vector used by this threat, but there are two scenarios that we believe are highly possible explanations for the spread of this ransomware:

 

  • Arrival through social engineering emails designed to trick users to run the malware and activate the worm-spreading functionality with the SMB exploit
  • Infection through SMB exploit when an unpatched computer is addressable from other infected machines

Pretty sure you've got it right there. There's a google search you can perform that provides links to infected websites that are used to host the payload as linked to in the email.

I'm not sure iof what is generating the spam in the first place but likely from pwnd mailboxes.

Microsoft is it's own worst enemy actively allowing Malware to be advertised within its own products.

 

See current Skype ad below which directs to one of those fake anti-virus malware sites:

 

 

Not to mention the quantity of dubious Apps in the Windows Store last time I looked; unsurprising why people are so concerned about Windows 10 telemetry and increased advertising pushed to the desktop / Explorer.

It's money over sense/responsibility. Same with Stuff, NZ Herald and others running these sponsored links.

 

Meanwhile, someone added Geekzone to the Easylist and blocks everything (not only ads but other scripts too). Not because we distribute malware but because this person thinks he's the only one to dictate what we should show. And yes, he's a Geekzone registered user.

I imagine by now most good AV signatures have been updated

Clint

 

 

 

Signatures were available for both the malware and the SMB attack around mid-April from some security vendors (well before the big outbreaks). For all the frothing at the mouth about this malware suddenly appearing it was known about already.

 

It boils down to people have a combination of : old unpatched OSs/ bad email security-anti-spam / poor network security / and poor desktop AV.

do you have a source that shows that the AV signatures to understand "WannaCrypt, WannaCry, WanaCrypt0r, WCrypt, WCRY" were available prior to May 12 please?

From Symantec:

 

"Symantec Endpoint Protection (SEP) and Norton have proactively blocked any attempt to exploit the vulnerabilities used by WannaCry, meaning customers were fully protected before WannaCry first appeared. SEP14 Advanced Machine Learning proactively blocked all WannaCry infections on day zero, without any updates."

that's not a signature.  I'm curious to know more about this piece:

 

"Signatures were available for both the malware and the SMB attack around mid-April from some security vendors (well before the big outbreaks). "

Sure...

 

https://support.sonicwall.com/kb/229442

 

 

If you are a SonicWall customer, and you have an active Gateway Anti-Virus subscription, your SonicWall firewall has been protecting your network from WannaCry (also known as WanaCrypt0r or WannaCrypt) ransomware since April 20, 2017.

 

There are also IPS signatures for the worm side of things...

 

 

 

https://blog.sonicwall.com/2017/05/sonicwall-protects-customers-latest-massive-wannacry-ransomware-attack/

 

 

 

I suspect there will be other vendors with similar stuff, as the IPS signatures were derived from the leaked NSA hacks. And most security vendors having a group where they share signature data. Sandbox technology will also pick up such things (and then provide a source to derive new signatures).

I've updated the previous post to show the image - the poster updated over it to show a link. No problem.

 

Folks, remember that now that we are serving only HTTPS if you add images from HTTP these will not appear as most browsers will deem these "unsafe".
