Please reference this case SHA1: a31ccbbb428230362a74ca9dee01c6c96757bac8

 

Hi,

 

we have a second case with ransomware that I do not know... I have no ransom note yet - working on that - so I can not let ID Ransomware run on it.

I only have (many) corrupted files.

 

When I look at the data all .pdf, .ppt, .xls and .jg are ok. The virus only encrypted .doc(x) files.

 

Does this ring a bell?

Do all files have the same extension? MaktubLocker and CTB-Locker commonly create one random extension that is applied to all files. I don't see anything particularly interesting in the sample file myself (other than it is encrypted).

 

You should see a "_DECRYPT_INFO_utrllge.html" if it is MaktubLocker, or "!Decrypt-All-Files-utrllge.html" if it is CTB-Locker. It's hard to automate identification of these two without having the ransom note to match the extension.

ok I'll check for those 2 files, and we are getting the ransom note back normally through RAW recovery

 

But, if it's MaktubLocker or CTB-Locker - are there solutions currenty?

 

Regards

Afraid both have no solution currently, they both use very strong cryptography with no slip-ups.

 

More info on MaktubLocker and CTB-Locker:

Most likely Maktub Locker...we have not received any recent reports of CTB-Locker activity other than the CTB-Locker for Websites variant.

There's been some resurgence of it in Italy it seems. JAMESWT has been finding some new samples in the last week or two. https://twitter.com/search?q=%23ctblocker

CTB-Locker is definitely still active, I've had about 3 different files submitted. The files it uses to infected are called factuur and have a pdf icon, so definitely targeting Italians.

Thanks for the update Demonslay335 & xXToffeeXx.

It would be helpful for that kind of info to be posted in the CTB-Locker Support & Discussion topic.

Anyway then, we are back to either or with this .utrllge extension.
