.BAT Ransomware – How Did I Get It and What Does It Do?
The primary method that is used by Dharma ransomware to infect computers is likely done via the infection file being sent to you as a result of a malicious spam via e-mail. These e-mails contain the virus file added as an attachment and this file may pretend to be:
- An invoice.
- A receipt for an order.
- An important document from your bank.
- Something work-related.
- Security document sent to recover missing password or something similar.
Another possible scenario for replication is if the virus file of .BAT ransomware is directly uploaded on several different types of sites that are compromised and to appear as if it is some sort of seemingly legitimate software download. Usually, these types of virus files can pretend to be:
- Portable programs.
