AWS API calls indicating Route 53 log tampering

ID:aws_route53_evasion
Data type:AWS CloudTrail
Severity:
Informational
-
Medium
MITRE ATT&CK:TA0005:T1562.008

Description​

AlphaSOC detected an unexpected use of DeleteResolverQueryLogConfig or DeleteQueryLoggingConfig API calls. These actions may indicate an attempt to disable or delete AWS Route53 query logging configurations. Adversaries may disable DNS logging to evade detection and obscure their activities.

Impact​

Disabling Route53 query logging can impair an organization's ability to detect and investigate DNS-based threats. Without these logs, security teams lose visibility into DNS queries, making it challenging to identify malicious activities.

Severity​

Investigation and Remediation​

Investigate the specific Route 53 configurations that were modified. Review AWS CloudTrail logs to identify the source of these changes. Analyze network traffic patterns for any suspicious activities or unauthorized data transfers.
