Problem
Session theft is not detected because the creator monitors password changes but not unfamiliar device or session activity.
Solution
Root Cause / Diagnostic:
Session theft utilizes stolen browser session cookies (__Secure-1PAPISID, SSID) rather than user passwords, completely bypassing password change alerts. Because the attacker operates within a valid, pre-authenticated cryptographic token, traditional password-monitoring mechanisms show no anomalies while the intruder navigates channel controls freely.
Actionable Fix:
1. Session & Device Audit: Navigate immediately to Google Account Security ([link removed]) and examine the active sessions list for unfamiliar IP addresses, operating systems, or geographic locations.
2. Sign-Out of Unrecognized Sessions: Click on each suspicious session, select "Sign out", and invalidate the active session cookies across all non-primary hardware.
3. Automated Security Alerts Configuration: Enable real-time Google Workspace / Account suspicious activity alerts and configure email/SMS push notifications for new device logins.
Pro Tip:
Info-stealer malware doesn't guess passwords; it steals active session cookies from your browser cache. Check your 'Your devices' page weekly to spot active intruder sessions that never triggered a password prompt.
