Leaked credentials arenāt just a one-time mishapāthey often linger as active security threats for years. While many companies are getting better at detecting when secrets like API keys, database logins, or cloud credentials slip into public repositories, the crucial follow-up stepāremediationāis lagging dangerously behind. GitGuardianās State of Secrets Sprawl 2025 report paints a troubling picture: secrets exposed as far back as 2022 are still being found valid today, highlighting an urgent operational failure across industries.
Exposed Credentials Still Valid After Years: A Security Time Bomb
A new wave of research confirms a deeply rooted security issue: organizations are failing to revoke or rotate credentials even after their exposure is detected. GitGuardianās analysis of GitHub data spanning from 2022 to 2024 reveals that most leaked secrets continue to be valid long after their discovery.
Key Insights:
Secrets remain valid long after exposureāsometimes for yearsāmaking them active entry points for attackers.
The underlying issue often
Hardcoded secretsālike those embedded in source codeāremain prevalent and difficult to manage. Revoking them can disrupt production environments and services.
Legacy systems pose a technical barrier, often incompatible with ephemeral credentials or automated key rotation.
The Growing Risk Profile
Analysis of leaked secrets over three years indicates that some of the most critical infrastructure credentials are being exposed and left valid:
MongoDB credentials: Expose sensitive customer and system data, posing serious breach risks.
Cloud service keys: Google Cloud, AWS, and Tencent Cloud keys were frequently exposed and still valid, giving attackers potential access to codebases, storage, and customer environments.
SQL credentials (MySQL/PostgreSQL): Despite some progress in remediation, a significant number remain publicly accessible.
These are not test environments. These are production credentials with direct links to real systems.
Cloud Credentials: The Fastest Growing Risk
In 2023, active cloud keys made up 10% of valid exposed secrets. By 2024, that rose to nearly 16%. The increased adoption of SaaS and cloud-native tools likely explains this jump, but it also signals inadequate access management.
Interestingly, database secrets showed a decline in persistence. From 13% in 2023, valid database keys dropped to 7% in 2024, hinting that recent attention to database securityāpossibly from high-profile breachesāis beginning to work.
Still, cloud keys are taking their place as the new top threat, driven by the complexity of cloud access and rapid development cycles.
What Undercode Say:
The takeaway from GitGuardianās findings is more than just statisticsāitās a red alert for operational maturity in cybersecurity.
In our assessment, three core issues explain the failure in secret management:
- Operational Friction: Many organizations lack the tools to perform credential rotation at scale. Revoking a key often requires updating multiple interconnected services, triggering downtime or production disruptions.
Security Prioritization: With limited resources, teams often address only the most urgent threats. If a secret was leaked but hasnāt (yet) led to a known compromise, itās often deprioritizedādespite being a ticking time bomb.
Tooling and Automation Gaps: While cloud providers offer robust tools like AWS STS, IAM Roles, or GCP Workload Identity Federation, adoption is inconsistent. Teams continue using static keys out of convenience or legacy requirements.
This isnāt just poor hygieneāitās a systemic vulnerability. Hardcoded secrets, outdated credential models, and a lack of secrets lifecycle management are allowing threats to persist in the wild for years. Attackers donāt need zero-days when they can use publicly available, still-valid API keys.
We also observe a paradox: as the DevOps landscape matures with automation and CI/CD pipelines, secret management hasn’t kept pace. Integrating secret rotation into CI/CD, leveraging dynamic secrets via Vault or AWS Secrets Manager, and enforcing expiry policies must become part of the build process.
Undercode strongly recommends:
Automated detection using Git scanning tools.
Immediate rotation on detection, not just alerts.
Short-lived credentials for all external and internal workloads.
Secrets-as-a-service platforms that manage access and audit logs in real time.
Infrastructure-as-code integration that prohibits committing secrets from the start.
Until organizations shift to a ācredentials are disposableā mindset, they will continue to face prolonged risk from past exposures. Treat credentials like session cookiesānot lifetime access keys.
Fact Checker Results:
- GitGuardianās data comes from real-world GitHub repositories, not simulated environments.
- The trends showing increased cloud key exposure align with wider adoption of cloud-native development.
- Decline in database secret persistence appears legitimate, though long-term verification would require third-party studies.
Prediction:
As companies move deeper into cloud-native ecosystems, we expect exposed cloud secrets to become the number one attack vector in supply chain attacks by late 2025. Developers will increasingly rely on third-party integrations, making secrets management more complex and fragmented. The transition to ephemeral, identity-based authentication models will be forcedānot chosenādriven by mounting breaches and new regulatory pressures. Expect automated secrets rotation tools and policy-enforced commit scanning to become standard in most DevSecOps pipelines by 2026.
