Yes, they are unable to trace where it has come from but it seems thus far to be targeting important businesses rather than private computer systems, so UK hospitals, some places in Russia and the US. Apparently it was something that was created in the US by the government and accidentally leaked and now being used against large businesses and corporations. I don't believe we need to be concerned however it is better safe than sorry. Basically it throws up a page demanding information release for ransom like you would after clicking a dodgy link. Here is an article on it:
Although it's targeting corporate businesses now, it could just be a matter of time before it ripples.
This is the reason Apple declined to create a backdoor for the FBI to enter the iphone of a suspected terrorist, the insecurity of it. Virtually nothing can be kept from hackers these days.
The same common sense that applies to avoiding viruses on a daily basis applies here:
- DO NOT open emails period nevermind attachments from unknown senders and be wary of those from internet acquaintances.
- DO NOT open emails from familiar senders if there is no title.
- DO NOT download freeware, especially if it's something that isn't supposed be free such as a Microsoft Office download.
- DO NOT click sketchy links. I.e: those that appear in ad or spam tweets.
- DO NOT stream movies or television shows illegally. The sources are NOT secure.
- DO NOT click anything in a popup. Use a popup blocker to avoid them entirely.
- BACKUP YOUR FILES.
- Have a known and trusted security software such as MalwareByes, Norton, AVG, and/or SuperAntiSpyware and do regular scans.
Bonus tip: Use a Mac as they're less susceptible to viruses than PCs.
