Changes are enumerated below.

Rules​

• [New] OUTLIER-S00033 AWS DynamoDB Outlier in PutItem Events from User
  • [Disabled by Default] This rule detects an unusual amount of PutItem events to a DynamoDB resource within an hour time period (DynamoDB data events are required). Verify the user is authorized to modify the DynamoDB tables and instances. This rule is disabled by default due to potential volume of signals, before enabling consider excluding authorized users via match lists, and adjust floor value and model sensitivity as needed.
• [New] FIRST-S00100 First Seen User Enumerating Custom AWS Bedrock Models
  • [Disabled by Default] Detection of a user account's first enumeration of custom AWS Bedrock models via ListCustomModels API. Verify the user is authorized for AWS Bedrock access. The http_userAgent field indicates whether a browser or CLI tool was used. This rule is disabled by default due to potential high volume of alerts, particularly from service accounts. Before enabling, consider excluding authorized users and service accounts (such as CNAPP monitoring accounts with timestamp-based usernames) through rule tuning expressions.
• [New] OUTLIER-S00032 Outlier in Data Transferred from an S3 Bucket by User
  • [Disabled by Default] This rule detects an unusual amount of data transferred outbound from an S3 bucket (requires AWS Data events are required). Verify if the user, role and IP address associated with this activity are authorized. This rule is disabled by default due to potential signal volume. Before enabling, consider excluding authorized users with regular large transfers via match lists, and adjust floor value and model sensitivity as needed.
• [New] OUTLIER-S00031 Outlier in Data Transferred into an S3 Bucket by User
  • [Disabled by Default] Detects unusual amounts of inbound data transfers to S3 buckets (requires AWS Data events). Verify if the user, role, and IP address associated with this activity are authorized. This rule is disabled by default due to potential alert volume. Before enabling, consider excluding authorized users with regular large transfers via match lists, and adjust floor value and model sensitivity as needed.
• [Updated] MATCH-S00069 O365 - Users Password Reset
  • Changed Entity and Summary, replacing user_username with targetUser_username.
• [Updated] MATCH-S00449 Powershell Execution Policy Bypass
  • Fixed camel case in commandLine field.
