Data Theft Mechanism via Infostealer Trojans
Browser database files are encrypted using standard operating system system libraries. If malware runs under the current user account, it accesses the same decryption interface, instantly gaining access to text passwords, cookies, and payment forms.
How to Protect Accounts from Stealers
- Move password storage to dedicated managers with an independent master password
- Disable autocomplete for payment forms and credit card numbers in the browser
- Use virtual disposable cards with spending limits for online shopping
- Regularly clear old saved sessions and temporary files from the browser memory
