Ok folks: I have never seen a Virus, Ransomeware or Malware attack that I could not find here till now. “.keepcalm”

A friend of mine has been nailed with this thing while he was gone over the weekend.

It only attacked his Server 2012 SR2 and VM's. The odd part is, it did not encrypt everything just some files..

He was running Clamwin and Sentinel. Oddly it removed both of them with out a trace. 

 

Also? The malware screen that pops up says nothing about payment for decryption.

All files that were hit were renamed .keepcalm

​We have tested the renamed files to see if it just did a mass rename? No go, you rename the extension and the file blows up talking about encryption.

 

The only thing we can find is listed here...

http://provirusesremoval.com/remove-keepcalm-virus/

 

I do not like the idea that this ransomeware is not listed anywhere I could find on Google, or Bleeping Computers! Also.. Once on the page all it advertises is the company that wants to "Scan for free" then charge you to remove it. The company?

https://www.enigmasoftware.com/products/spyhunter/

All seems to me to be really fishy.. 

 

OH! and you can install anything you want and run it.. The network was unaffected only the server!

What have we tried, other than what I listed above?

Malwarebytes and list of other Antivirus, Malware, Spyware and Ransomeware testers.. they ALL show the system is clear.

We are truly open to any thoughts.

 

Thanks.

Don

The best way to identify the different ransomwares is the ransom note (including it's name), samples of the encrypted files, the malware file itself, any obvious extensions appended to the encrypted files, samples of the encrypted files and information related to any email addresses used by the cyber-criminals to request payment.

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections. If ID Ransomware cannot identify the infection, you can post the case SHA1 it gives you in your next reply for Demonslay335 to manually inspect the files.

Example screenshot:

Samples of any encrypted files, ransom notes or suspicious executable's (installer, malicious files, attachments) that you suspect were involved in causing the infection can be submitted (uploaded) here with a link to this topic. There is a "Link to topic where this file was requested" box under the Browse... button. Doing that will be helpful with analyzing and investigating by our crypto malware experts.

Globeimposter variant.  Go here https://www.bleepingcomputer.com/forums/t/644166/globeimposter-20-fix-extension-ransomware-support-topic/?p=4218395

 

 

Per Demonslay:

 

 

Please see: https://twitter.com/malwrhunterteam/status/859301049638809600

 

This is a variant of GlobeImposter. Afraid the newest one is not decryptable. You can only restore from backups, or try recovery software such as Recuva and hope to be lucky.

 

I believe this group hacks RDP, so make sure that is secured.

Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.

Thanks
