Previous attack uses just a wink smiley face attachment. But this time, the new attack vector is spreading thru emails with IMG<number>.jpg.js.zip format. It is reported that since 300,000 messages have been filter out and growing.

How are you infected (if you extracted the file):

  • launches Windows scripting host to run a command launching PowerShell with the execution policy bypass flag.
  • A file named sava.exe is then downloaded from the IP of 217[.]8[.]117[.]63 into the local temp folder and saved as 5203508738.exe, before it’s executed.

The ransom note:

You will be given then a 7 day window to pay the ransom, $600 via BTC.

This looks like the WannaCry attack. Is crazy to see how the hackers are using this attack as their favorite new attack. Is easy to infect the machines with the malware, and there is nothing we can do because windows will keep installing programs without asking us.

If you want to be safe and secure, then use Linux and navigate on the internet wisely.

Spam through the email is an old scam school, everyone should learn not to click on the links randomly.
I have not read all the data, but I do not think it is easy to close and encrypt all the data from a click of an image, any way you should be careful.

Use e-mail addresses with better filters, and do not publish them publicly.
Do not reply to any unknown e-mails.

It is being there are still non-educate individuals that can easily fall for this trick. They thought that it is interesting to see what the attach image are, click it and then it's too late, they feel victims. I agree that Linux are good, but it is not for everyone. Windows is still number one as far as desktop OS market share around the world.

Just think before you click and be very attentive on every mails coming into your inbox specially from unknown source.
