Query: mitigate Keychain
Matching passage: T1555.001 Keychain. Tactics: credential access. Description: Adversaries may acquire credentials from Keychain. Keychain (or Keychain Services) is the macOS credential management system that stores account names, passwords, private keys, certificates, sensitive application data, payment data, and secure notes. There are three types of Keychains: Login Keychain, System Keychain, and Local Items (iCloud) Keychain. The default Keychain is the Login Keychain, which stores user passwords and information. The System Keychain stores items accessed by the operating system, such as items shared among users on a host. The Local Items (iCloud) Keychain is used for items synced with Apple’s iCloud service. Keychains can be viewed and edited through the Keychain Access application or using the command-line utility <code>security</code>. Keychain files are located in <code>~/Library/Keychains/</code>, <code>/Library/Keychains/</code>, and <code>/Network/Library/Keychains/</code>.(Citation: Keychain Services Apple)(Citation: Keychain Decryption Passware)(Citation: OSX Keychain Schaumann) Adversaries may gather user credentials from Keychain storage/memory. For example, the command <code>security dump-keychain –d</code> will dump all Login Keychain credentials from <code>~/Library/Keychains/login.keychain-db</code>. Adversaries may also directly read Login Keychain credentials from the <code>~/Library/Keychains/login.keychain</code> file. Both methods require a password, where the default password for the Login Keychain is the current user’s password to login to the macOS host.(Citation: External to DA, the OS X Way)(Citation: Empire Keychain Decrypt)
Near-miss passage: T1555.006 Cloud Secrets Management Stores. Tactics: credential access. Description: Adversaries may acquire credentials from cloud-native secret management solutions such as AWS Secrets Manager, GCP Secret Manager, Azure Key Vault, and Terraform Vault. Secrets managers support the secure centralized management of passwords, API keys, and other credential material. Where secrets managers are in use, cloud services can dynamically acquire credentials via API requests rather than accessing secrets insecurely stored in plain text files or environment variables. If an adversary is able to gain sufficient privileges in a cloud environment – for example, by obtaining the credentials of high-privileged [Cloud Accounts](https://attack.mitre.org/techniques/T1078/004) or compromising a service that has permission to retrieve secrets – they may be able to request secrets from the secrets manager. This can be accomplished via commands such as `get-secret-value` in AWS, `gcloud secrets describe` in GCP, and `az key vault secret show` in Azure.(Citation: Permiso Scattered Spider 2023)(Citation: Sysdig ScarletEel 2.0 2023)(Citation: AWS Secrets Manager)(Citation: Google Cloud Secrets)(Citation: Microsoft Azure Key Vault) **Note:** this technique is distinct from [Cloud Instance Metadata API](https://attack.mitre.org/techniques/T1552/005) in that the credentials are being directly requested from the cloud secrets manager, rather than through the medium of the instance metadata API.
