[German]During the last hours I stumbled twice over the keyword WannaCry. What looks like a return of this pest may turn out to be a scam or fraud email campaign. I thought I’d post it here for admins’ information.
Two hits on WannaCry
The first impact came during browsing through postings on a German administrator forum, when I came across the article Wannacry – Malwarebytes. The question ‘could it be the start of a new WannaCry’ sprang into my head. But due to the nature of the forum posting I did not investigate further (the posting asked questions, that no admin will ask after a real WannaCry infection, hitting network computers.

Then I saw the above Tweet, which immediately triggered an ‘Ok, an explanation’ reaction.
Scammer plays WannaCry
The background to the MalwareTech Tweet is described by The Register in the article WannaCry is back! (Psych. It’s just phisher folk doing what they do). Thursday, 21.06.2018 was not only Midsummer.

We are receiving reports this morning of a #wannacry threat email being widely received.
It is designed to cause panic resulting in payment of their empty threat.
If you have concerns speak with your IT company.

Affected users received the e-mail shown in the tweet above. Within the mail, the senders claim that WannaCry is back and that all files on the victim’s computer will be encrypted.

So if something like this comes to your attention: Just delete the mail and continue with your daily work.
