.BACKUP Files Virus – How Does It Spread
The main method which is used by the .BACKUP files ransomware is to target you via e-mail messages, mostly malicious spam. These e-mail campaigns use deceptive tactics to trick you into opening the attachments within them and they often pretend as the files attached are:
- Invoice for a purchase.
- An order confirmation file.
- A fake bank account report.
- New funds into your account.
- Receipt.
- A fake digital signature.
These e-mails are often pretending as if they come from big companies, like eBay, DHL, FedEx, PayPal and several others. In addition to this, the e-mails are also masked with fake claims that they originate from employees of those organizations, for example:
In addition to via e-mails, the malwar emay also use other methods to infect your PC, such as upload the infection file on torrent or other suspicious sites as a legitimate setup of a program, licence activator or a portable app of some sort.

- %AppData%
- %Local%
- %LocalLow%
- %Roaming%
- Receipt.
- %Temp%
Among the malicious files is the ransom note of the .BACKUP file variant of CryptoMix ransomware. It is named _HELP_INSTRUCTION.txt and just like previous versions of this virus, it aims to get victims to contact the crooks via e-mail:

DECRYPT-ID-{RANDOM NUMBER}
After this, the ransomware also drops another executable type of file in the %ProgramData% directory, which runs a script that stops some services of Windows, primarily related to the backups of your computer. This happens by running the following service stop commands in Windows Command prompt:
→ sc stop VVS
sc stop wscsvc
sc stop WinDefend
sc stop wuauserv
sc stop BITS
sc stop ERSvc
sc stop WerSvc
cmd.exe /C bcdedit /set {default} recoveryenabled No
cmd.exe /C bcdedit /set {default} bootstatuspolicy ignoreallfailures
C:\Windows\System32\cmd.exe” /C vssadmin.exe Delete Shadows /All /Quiet
The last of the commands aims to delete the shadow volume copies of the infected computer and hence make their recovery more difficult than before.
.BACKUP Ransomware – Encryption
