DJVU files lost- Partition formatted and a few new files created

#1 Post by aimen »

Hello,

My PC was attacked by STOP ransomware. I lost all files due to .erif encryption. By mistake one partition was formatted and I stored 1 GB of word pdf files. Now I am unable to access the deleted files . Has my data overwritten? is there away to get erif files dencrypted? I have lost my Phd research data if some one can help ASAP it will be a great favor.

word files or pdf files?

Now I am unable to access the deleted files .
Which files have been "deleted"? How?
Has my data overwritten?
[/quote]Which data?
is there away to get erif files dencrypted?
There are some many ransomware algorithms - please check a search engine on that matter.
I have lost my Phd research data if some one can help ASAP it will be a great favor.
Help is only possible based on a comprehensible problem description.
Unprecise descriptions trigger a negative mood of helping people and diminishes their motivation.

DJvu family ransomware I guess. It left a note of providing 980$ to get my data back. All of the data is lost; word docs, pdf, images etc. As a partition was formatted and all the data is lost. on the same partition after formatting I saved 3 word documents, and a few other files. So this disk which was formatted and now contains 1GB data can it be recovered?
I have tried Photorec and some files recovered but these are text files or images and are not functional. Most of these are broken as the photorec manual described named with ''b'' . My Phd research data is also word or pdf files. All files are renamed as .erif and cant be opened.

I used testdisk for one file it gave this response

I still don't get.
Who formatted the partition? When?
Please file a precise report.
Use a timeline. State what your disk has been before, partition layout etc.
State what it's layout was after.
There are two things, a ransomware attack and formatted partition. That does not fit together.
I won't ask you a third time.

Please contact your local police station. If you were here in Germany local police would tell you if they aware of a decoding tool.
Ask a professional recovery company or your antivirus software provider if you have one.
