Hacker Behind Massive Ransomware Outbreak Can't Get Emails From Victims Who Paid (vice.com)
Joseph Cox, reporting for Motherboard: On Tuesday, a new, worldwide ransomware outbreak took off, infecting targets in Ukraine, France, Spain, and elsewhere. The hackers hit everything from international law firms to media companies. The ransom note demands victims send bitcoin to a predefined address and contact the hacker via email to allegedly have their files decrypted. But the email company the hacker happened to use, Posteo, says it has decided to block the attacker's account, leaving victims with no obvious way to unlock their files. [...] The hacker tells victims to send $300 worth of bitcoin. But to determine who exactly has paid, the hacker also instructs people to email their bitcoin wallet ID, and their "personal installation key." This is a 60 character code made up of letters and digits generated by the malware, which is presumably unique to each infection of the ransomware. That process is not possible now, though. "Midway through today (CEST) we became aware that ransomware blackmailers are currently using a Posteo address as a means of contact," Posteo, the German email provider the hacker had an account with, wrote in a blog post. "Our anti-abuse team checked this immediately -- and blocked the account straight away.
While this doesn't do anything to improve life for the poor folks trying to retrieve their files, this type of aggressive approach may be required to eliminate the incentives for ransomware creators. It's truly the nuclear option, as the fallout is likely to hurt many unintended targets, but it could end the war.
Let the scammer's email addy active and be accused of being accessory to racketeering?
Tough shit for the ransomware victims, but they just had to do it.

It would be funny, except that people are paying the ransom and not getting their files back. Perhaps there will be a positive result here and people will start to get the idea that it is never worthwhile to pay the ransom and to keep backups instead. Oh, who am I kidding? That is #5 of The Six Dumbest Ideas in Computer Security.
Out of curiosity, why don't anti-viruses create a random file on disk and flag any process that modifies it as a suspected ransomware (for manual or automated intervention)?
It is always a temptation to an armed and agile nation
To call upon a neighbour and to say: --
"We invaded you last night--we are quite prepared to fight,
Unless you pay us cash to go away."
And that is called asking for Dane-geld,
And the people who ask it explain
That you've only to pay 'em the Dane-geld
And then you'll get rid of the Dane!
It is always a temptation for a rich and lazy nation,
To puff and look important and to say: --
"Though we know we should defeat you, we have not the time to meet you.
We will therefore pay you cash to go away."
And that is called paying the Dane-geld;
But we've proved it again and again,
That if once you have paid him the Dane-geld
You never get rid of the Dane.
It is wrong to put temptation in the path of any nation,
For fear they should succumb and go astray;
So when you are requested to pay up or be molested,
You will find it better policy to say: --
"We never pay any-one Dane-geld,
No matter how trifling the cost;
For the end of that game is oppression and shame,
And the nation that pays it is lost!"
