Attackers Breached JetBrains Cadence via Unpatched TeamCity, Extracting AWS Credentials

Attackers exploited an unpatched TeamCity flaw to breach JetBrains' own Cadence environment and exfiltrate AWS credentials — all Cadence users should treat stored secrets as compromised.

JetBrains is urging Cadence users to revoke and rotate all credentials following a security incident last month in which unidentified threat actors exploited a recently disclosed critical vulnerability in TeamCity to breach its own environment.

"Cadence users should immediately revoke or rotate all credentials and secrets that may have been used to run their Cadence executions," JetBrains said.

Editorial Analysis

Framed for the CISO & Security Leaders desk

Why it matters

A vendor's own environment was breached via a known TeamCity vulnerability, resulting in AWS credential exposure for downstream Cadence users — a textbook supply-chain compromise.

What to do

Direct teams to immediately rotate any credentials associated with JetBrains Cadence and review access logs for anomalous AWS API activity.

Board brief

A breach of JetBrains' own CI/CD infrastructure exposed customer cloud credentials, demonstrating how vendor compromises cascade to enterprise environments.
