Overview of the Bpant Ransomware

Bpant is a type of ransomware that uses strong encryption algorithms to lock files on an infected system. It appends the ".Bpant" extension to the encrypted files and leaves ransom notes, urging victims to pay a Bitcoin ransom for file recovery. Bpant disables security tools, deletes backups, and spreads through several methods, including phishing emails and unpatched vulnerabilities.

Key Characteristics

1. Encrypts a Wide Range of Files: Targets documents, databases, backups, and more.
2. Renames Files: Appends unique victim IDs, attacker email addresses, and the ".Bpant" extension.
3. Drops Ransom Notes: Leaves instructions in text files across all directories.
4. Deletes Backups: Attempts to remove Volume Shadow Copies to block recovery.
5. Geo-targeting: Avoids encryption in certain regions to maximize profits.
6. Disables Security Tools: Deactivates antivirus programs and firewalls.

How Bpant Infects Systems

1. Phishing Emails: Malicious attachments or links pretending to be invoices or urgent notifications.
2. Compromised RDP Access: Exploiting weak passwords on Remote Desktop Protocol (RDP).
3. Unpatched Vulnerabilities: Exploiting outdated software with remote code execution flaws.
4. Malicious Downloads: Fake installers, pirated software, or crack/keygen tools.
5. Malvertising: Redirecting users through malicious advertisements to infected sites.
