Research shows information stealers routinely exfiltrate desktop screenshots, browser vaults, extensions and MFA secrets, sometimes uploading directly to Telegram; a monitored collection reaches about 1.5M logs/week and 120M unique logs. Demonstrated tools and techniques include extracting TOTP secrets from an Authenticator extension, using John the Ripper/hashcat on KeePass dumps, and automated account validation with turnkey BL tools checker; Chrome’s application‑bound encryption is helpful but has practical bypasses. Defensive measures: block risky extensions, enforce strong master passwords, avoid disabling AV, and test/safeguard credentials.
