My pictures are converted to large size files 23GB each suddenly and can't be opened

[hsnmysr]

Hi,

 

Please help me

I have transferred pictures that I took from a camera (Canon, and from my mobile"Samsung") to my laptop, Microsoft surface with windows 10 operating system,

These photos were fine and opened smoothly, and each one is a few megabytes in size,

A few weeks later, I tried to back up my pictures and files on external hard drives; I was surprised that all my photos were of total 5 terabytes! And each one is 23 Gigabyte in length, and they can't be opened. I know this is a fake size as my storage in the laptop is a total of 1 TB, and the Kaspersky total security doesn't recognize any problem.

I am really worried as those pictures are very important to me

I hope you can find a solution to my problem as I am a researcher and if I lose those pictures, I lose lots of work for months!

Please help

 

Many thanks

Hassan

Hello,

Using notepad.exe to open the related picture jpg format, Could you see "JFIF" string?

This is the first time I've heard of ransomware that fills files with junk data and makes them bigger. Larger files have a great impact on the efficiency of encryption and the final degree of completion.?
