A friend sent me the bitcoin address, they've already collected 2600$. [EDIT] Now 3230$ Source: https://blockchain.info/address/1Mz7153HMuxXTuR2R1t78mGSdzaA...

it seems like a trivially avoidable mistake to use a single wallet for all collections, but maybe i shouldn't be giving them ideas...

As someone affected by the ransomware - did anyone else notice empty console windows popping up from time to time the days before the ransomware triggered the encryption?

This is most likely due to the Office bug: https://www.digitaltrends.com/computing/here-is-a-fix-for-mi...

> with WannaCry it was alleged a nation state was likely responsible for spreading the malware: North Korea Is there any evidence for this? Looks like another fake rumor.

There's an article on it in NYT which provides a short list of the reaons: https://www.nytimes.com/2017/05/22/technology/north-korea-ra...

It basically comes to it looking like Lazarus Group

The WannaCry attacks used the same command-and-control server used in the North Korean hack of Sony Pictures Entertainment in 2014, which wiped out nearly half of the company’s personal computers and servers.

...

Other digital crumbs linking the North Korean group to WannaCry include a tool that deletes data that had been used in other Lazarus attacks. The hackers behind WannaCry also used a rare encryption method and an equally unusual technique to cover their tracks.

I did see those console windows here on Windows 10 but I am not (yet?) affected. So might also be related to something else (Windows Defender updates?).

Earlier quoted context omitted.

As if this attack purely relied on people clicking on emails. Maybe that's 1 person out of 10.000 but obviously this used various other methods to spread.

how else could it spread? flash exploit? Skype? Wanna cry spread to computer connected to network but individuals at home probably aren't connected to a local network unless there are multiple computers

You are thinking "trojans," not viruses. Viruses spread without any user interaction by exploiting vulnerabilities in clean, but accessible machines.

Ransomeware used to be purely trojans, but newer iterations now come with a viral component based (at least partially) on that leaked NSA toolkit.

Security researchers matched parts of the WannaCry code to previous viruses that were thought to originate from NK. Of course they also said anyone could of copied and pasted the code and just made it look like that, but the media ignored that part.

> The haystack needle Mehta presented Monday now connects Lazarus to WCry, although the tie connecting the two isn't precisely clear just yet. WCry's creators may have deliberately added code found in Cantopee in an attempt to trick researchers into mistakenly believing Lazarus Group is behind the ransomware. Researchers at antivirus provider Kaspersky Lab said such a "false flag" is plausible but improbable. The Cantopee code snippet, the researchers explained, was removed from later versions of WCry, making it hard to spot and hence ill-suited to act as a decoy.

What a clickbait headline. A paltry $3k and yet the article calls this a "MASSIVE ransomware outbreak". I would be curious to see what a "minor" outbreak is.

it's not, my previous company took everything offline - they got infected via connections to their offices in Ukraine. lots of companies in the Ukraine are infected.

company I work for disabled all working from home VPN accounts for the time being until we do a security audit

There are reports of hundreds to thousands of machines infected across multiple firms in multiple countries. I'd bet >99% of people are never gonna send the $300 in bitcoin to decrypt their machine, instead they'll just clean and restore as much as they can. The $3k is 11 people desperate to restore all their data now, more may come in the future after people have exhausted other options, but the vast majority will never pay unless their backups were hit too.

That's not enough anymore: good ransomware will look for backup systems and wipe those out before proceeding. You need read-only, airgapped backups before you can consider yourself safe.

That doesn't help for targeted attacks, which corrupt the backups as they are being written. Not sure how to protect against that though.

An easy option is to use an offsite backup service that keeps versioned history (e.g. http://www.rsync.net or http://www.spideroak.com).

Not sure about Spideroak but in the case of rsync.net they duplicate snapshots and store them outside of your main account so even if your account gets compromised and an attacker deletes all your backups you're still safe.

how can they infect an external drive that backed up the data before the infection?

Why would the malware care about if it is an external or internal drive?
