Chrome Browser Login Data

Google's Chrome browser stores some login data of accessed websites, that can provide the URLs and usernames used for authentication.

 

On Windows, this information is stored in the following location:

C:\Users\[Username]\AppData\Local\Google\Chrome\User Data\Default\Login Data.

 

This file is a database file and can be opened in software such as DB Browser For SQLite. The ‘logins’ and ‘stats’ tables are of immediate interest to understand saved login data.

 

The passwords are not visible as they are encrypted. However, the encryption key is stored locally and can be used to decrypt saved passwords. The key is stored in the file C:\Users\[Username]\AppData\Local\Google\Chrome\User Data\Local State, which can be read with any text editor, such as Notepad, and searching for the “encrypted_key” value. The tool decrypt_chrome_password.py (referenced) can decrypt the AES-encrypted passwords to plaintext.

Sections

ID Name Description
IF010Exfiltration via Email

A subject uses electronic mail to exfiltrate data. This can be achieved through including data in the email subject line or body, or utilizing email attachments to send files.

IF008Inappropriate Web Browsing

A subject accesses web content that is deemed inappropriate by the organization.

IF018Sharing on AI Chatbot Platforms

A subject interacts with a public Artificial Intelligence (AI) chatbot (such as ChatGPT and xAI Grok), leading to the intentional or unintentional sharing of sensitive information.

MT020Ideology

A subject is motivated by ideology to access, destroy, or exfiltrate data, or otherwise violate internal policies in pursuit of their ideological goals.

 

Ideology is a structured system of ideas, values, and beliefs that shapes an individual’s understanding of the world and informs their actions. It often encompasses political, economic, and social perspectives, providing a comprehensive and sometimes rigid framework for interpreting events and guiding decision-making.

 

Individuals driven by ideology often perceive their actions as morally justified within the context of their belief system. Unlike those motivated by personal grievances or personal gain, ideological insiders act in service of a cause they deem greater than themselves.

IF010.001Exfiltration via Corporate Email

A subject exfiltrates information using their corporate-issued mailbox, either via software or webmail. They will access the conversation at a later date to retrieve information on a different system.

IF010.002Exfiltration via Personal Email

A subject exfiltrates information using a mailbox they own or have access to, either via software or webmail. They will access the conversation at a later date to retrieve information on a different system.

IF018.001Exfiltration via AI Chatbot Platform History

A subject intentionally submits sensitive information when interacting with a public Artificial Intelligence (AI) chatbot (such as ChatGPT and xAI Grok). They will access the conversation at a later date to retrieve information on a different system.

IF018.002Reckless Sharing on AI Chatbot Platforms

A subject recklessly interacts with a public Artificial Intelligence (AI) chatbot (such as ChatGPT and xAI Grok), leading to the inadvertent sharing of sensitive information. The submission of sensitive information to public AI platforms risks exposure due to potential inadequate data handling or security practices. Although some platforms are designed not to retain specific personal data, the reckless disclosure could expose the information to unauthorized access and potential misuse, violating data privacy regulations and leading to a loss of competitive advantage through the exposure of proprietary information.

ME006.008Generative AI Websites

A subject can access generative AI websites.

IF025.002User Account Sharing

A subject deliberately shares credentials for an individually assigned user account with another person, or uses credentials assigned to another individual without authorization. Individually assigned accounts are intended to be used only by the assigned account holder and are governed by organizational policy, access control requirements, and identity management processes. Sharing or using another person’s account violates these controls by moving access outside approved provisioning, delegation, and review mechanisms.

 

User account sharing typically emerges where convenience, workload pressure, informal delegation, or perceived access delays are prioritized over account-use policy. Teams may rationalize the behavior as necessary for shift coverage, urgent operational tasks, peer assistance, or temporary access needs. In other cases, a subject may share or receive account credentials to avoid onboarding delays, bypass access request processes, or complete work without obtaining the permissions formally required for their role.

 

When user account credentials are shared, the receiving individual gains access through an identity that was not assigned, approved, or reviewed for their use. This can bypass role-based access controls, segregation of duties, conditional access policies, approval workflows, and access review assumptions. The infringement is not dependent on malicious intent; the policy violation arises from the unauthorized transfer or use of identity-bound access.

 

User account sharing may expose sensitive systems, regulated data, approval functions, administrative consoles, or business workflows to individuals who have not been formally authorized for that level of access. In environments with compliance obligations, privileged workflows, or strict access governance requirements, user account sharing should be treated as a significant infringement and reviewed against the organization’s Acceptable Use Policy, identity governance standards, and disciplinary or remediation processes.
