In‑Depth Analysis

Infection Vector
Often arrives via phishing emails containing malicious attachments or links labeled with contract-themed filenames like dogovor.vbe, договор-2025-5.vbe, or приложение.vbe.

Behavioral Profile
Once opened, Batavia:

• Installs itself using Delphi-based code, hidden from the user.
• Harvests system logs and installed software details.
• Grabs Office file types, PDFs, screenshots, and content from removable devices.
• Exfiltrates data to external servers under attacker control.
• May maintain persistence via registry modifications or autorun entries.

Risk Assessment
If undetected, Batavia allows continuous data siphoning:

• Confidential documents (blueprints, contracts) may be leaked.
• Internal system structure and software profiles are exposed.
• Threat actors could leverage the data for industrial espionage or deeper compromise.

Severity is high. Stealth and persistence make it particularly dangerous to corporate networks.
