There are several different ransomware infections which append a random 4, 5, 6, 7, 8, etc character extension
to the end of all affected filenames (i.e. CTB-Locker, Crypt0L0cker, CryptON (Cry9, Cry36, Cry128, Nemesis), Maktub Locker, Alma Locker, Princess Locker, Locked-In, Mischa, Goldeneye, Al-Namrood 2.0, Cerber v4x/v5x and some Xorist variants).
Did you find any ransom notes
and if so, what is it's actual name? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. Most ransomware will drop a ransom note in every directory/affected folder where data has been encrypted. These notes are often created in multiple file formats (.txt, .html, .png) to ensure that the victim can open them. Check your documents folder for an image the malware typically uses for the background note. Check the C:\ProgramData (or C:\Documents and Settings\All Users\Application Data) for a randomly named .html, .txt, .png, .bmp, .url
The best way to identify the different ransomwares that use "random character extensions" is the ransom note
(including it's name), samples of the encrypted files
, any obvious extensions appended
to the encrypted files, information related to any email addresses
used by the cyber-criminals to request payment and the malware file
responsible for the infection.
You can submit samples of encrypted files and ransom notes to ID Ransomware
for assistance with identification
. 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.
