MITRE ATT&CK:TA0003:T1098

Description

AlphaSOC detected a successful login to 1Password. While successful logins are normal operations, certain patterns may indicate suspicious activity. Threat actors often target password managers to gain access to multiple accounts and systems through a single compromise, potentially obtaining credentials, API keys, and other sensitive data stored within the vault.

Impact

A compromised 1Password account could provide adversaries with access to all stored credentials, enabling lateral movement across multiple systems and services. This may lead to data breaches, unauthorized access to critical infrastructure, and further compromise of organizational assets and resources.

Investigation and Remediation

Verify the login source by checking IP addresses, geographic locations, and device fingerprints. If unauthorized access is confirmed, reset the master password, revoke all active sessions, and audit all credentials stored within the vault for potential compromise across connected systems.
