- Malspam.

Primarily, Delta Plus aims to reach personal files and encode them without being detected. Only by encoding valuable files, the ransomware can then try to blackmail victims into paying a hefty ransom fee.
As a data locker ransomware, the Delta Plus virus encrypts target files by utilizing a strong cipher algorithm. For encryption, it scans system drives and transforms the code of all files that are likely to store valuable data.
The complexity of applied changes leaves encrypted files completely inaccessible. Until their code is reverted back to its original state victims cannot use them. Unfortunately, access to the following types of files may be restricted by Delta Plus ransomware:
- Audio files.
- Image files.
- Video files.
- Document files.
- Backup files.
- Banking credentials, etc.
