ATTACKS & VULNERABILITIES

TLDR InfoSec

EU BORDER SYSTEM HAS THOUSANDS OF CRITICAL VULNERABILITIES

Thousands of vulnerabilities were discovered in the Schengen Information System II (SIS II), which is used by EU border agencies to track illegal migrants and suspected criminals. An audit by the European Data Protection Supervisor (EDPS) found that the system contained an excessive amount of accounts with administrative privileges, was vulnerable to hacker overload and unauthorized access, and that 69 external employees had access without proper clearance. The EDPS found no evidence of a breach but warned that a breach could be catastrophic.

CMS NOTIFIES 103K MEDICARE BENEFICIARIES ABOUT UNAUTHORIZED ACCOUNT CREATION

The HHS Centers for Medicare and Medicaid Services (CMS) was recently alerted that Medicare.gov accounts had been created for 103K individuals without their knowledge. The investigation determined that the accounts were created using information gathered from external sources. The unknown threat actor could use their access to view the user's Medicare beneficiary ID, coverage start date, birth date, and zip code.

ROLES HERE? ROLES THERE? ROLES ANYWHERE: EXPLORING THE SECURITY OF AWS IAM ROLES ANYWHERE

AWS IAM Roles Anywhere is a method for authenticating to AWS using certificates signed by a configured trust anchor. By default, the Roles Anywhere policy does not include any conditions, and any role attached to it could be assumed by any request signed by any trust anchor in that region. Unit 42 recommends specifying an ARN using conditions in the default policy, utilizing ACM-PCA for the trust anchor, and adhering to the principle of least privilege.

HIJACKING AMAZON EVENTBRIDGE FOR LAUNCHING CROSS-ACCOUNT ATTACKS

Attackers exploit AWS EventBridge's cross-account features using six MITRE ATT&CK attack patterns: establishing persistent backdoors via check-in events, creating bidirectional command and control channels, conducting reconnaissance by capturing all events, exfiltrating data in small chunks disguised as telemetry, lateral movement exploiting trust relationships, and exploiting vulnerable Lambda functions for unintended AWS API calls. These bypass traditional controls and evade detection because EventBridge PutEvents API calls aren't logged in CloudTrail. Defenses include Service Control Policies, specific event patterns, input validation, and monitoring CloudWatch for unusual activities.
