What Is the cloudbase-init Account in Windows ECSs?
In Windows ECSs, cloudbase-init is the default account of the Cloudbase-Init agent program. It is used to obtain the metadata and execute configurations when the ECS starts.
This account is unavailable on Linux ECSs.
Do not modify or delete this account or uninstall the Cloudbase-Init agent program. Otherwise, injecting the customized data for initializing the ECS generated using the Windows private image created based on this ECS will fail.
Security Hardening for Randomized cloudbase-init Passwords
In Cloudbase-Init 0.9.10, the security of randomized cloudbase-init passwords has been hardened to ensure that the hash values (LM-HASH and NTLM-HASH) of the passwords are different.
In Windows, the hash passwords are in the format of "Username:RID:LM-HASH value:NT-HASH value".
For example, in "Administrator:500:C8825DB10F2590EAAAD3B435B51404EE:683020925C5D8569C23AA724774CE9CC:::",
- Username: Administrator
- RID: 500
- LM-HASH value: C8825DB10F2590EAAAD3B435B51404EE
- NT-HASH value: 683020925C5D8569C23AA724774CE9CC
Use an image to create two ECSs, ecs01 and ecs02. Then, verify that the hash values of the cloudbase-init account for the two ECSs are different.
- LM-HASH and NT-HASH values of the cloudbase-init account for ecs01
- LM-HASH and NT-HASH values of the cloudbase-init account for ecs02
