CI/CD pipeline is the foundation of software development today – a smooth, automated process for quicker releases, agile sprints, and constant iteration. There’s an ugly underbelly, however. For attackers, CI/CD is no longer a playground for developers; it’s a valuable target.
As businesses are hurrying to automate, deploy, and scale, they are inadvertently leaving their pipelines vulnerable to disastrous cybersecurity attacks. Attackers don’t necessarily need to breach production if they can breach the pipeline that constructs it.
In this blog, we will examine where the threats lie, how attackers target CI/CD, and why businesses must employ a cyber security expert for hire to combat emerging threats.
Why the CI/CD Pipeline Is a Hacker’s Goldmine
CI/CD pipelines have access to all source code, environment variables, secrets, containers, cloud credentials, deployment tokens, and more.
Once an attacker has a foothold in a misconfigured CI/CD tool (like Jenkins, GitLab CI, CircleCI, or GitHub Actions), they can laterally move, add malware, and drop it directly into production. Your pipeline itself is the weapon, so to speak.
That is why CI/CD pipelines are so appealing:
- Automation scripts run with higher privileges
- Hardcoded credentials or secrets are usually kept in plaintext
- Security testing is generally reactive, not proactive
- Third-party integrations widen the attack surface
According to Verizon’s 2024 Data Breach Investigations Report, which looks at over 30,000 real security events and over 10,000 data breaches in 94 countries, 18% of last year’s breaches were some form of software supply chain compromise. That is a staggering jump from previous years, and it shows the growing threat to organizations’ development and deployment pipelines.
Common Attack Vectors in CI/CD
To fight off attacks, you must be aware of how the cracks get formed. Listed below are the common vulnerabilities normally overlooked:
1. Insecure Code Repositories
Poor access controls in a GitHub or GitLab repository make it easy for attackers to inject bad commits or exfiltrate sensitive code. Poor secret hygiene in public repos is low-hanging fruit.
2. Secret Leakage
Hardcoded API keys, database passwords, and access tokens in environment variables or YAML files are exposed to attacks. GitGuardian discovered 10 million secrets exposed in public GitHub repositories in 2023 alone.
3. Malicious Dependencies
NPM, PyPI, and DockerHub are riddled with typosquatting and malicious packages. These dependencies are automatically pulled and deployed without verification.
4. Overprivileged CI/CD Runners
Self-hosted agents or runners are typically over-permissioned and grant attackers elevated privileges if compromised.
5. Third-Party Toolchains
Third-party integrations (for monitoring, alerting, testing, etc.) increase the attack surface. If a connected service is breached, your pipeline is collateral damage.
Real-World Breach: Codecov (2021)
In 2021, attackers took over a Docker image used in Codecov’s Bash uploader script. The compromised script was shipped to thousands of user environments for weeks before being detected.
It enabled exfiltration of environment variables, such as tokens and credentials, from wherever the script was running.
This was a classic CI/CD pipeline compromise, and it cost hundreds of teams operational downtime, IP loss, and public trust.
Best Practices for Protecting Your Pipeline
Here is a step-by-step breakdown of defensive measures that any organization — and any cyber security expert for hire — should consider when assessing CI/CD risk:
- Apply Least Privilege Everywhere: Grant CI/CD agents access to only what they require. Utilize tightly scoped cloud roles, API permissions, and secrets.
- Use a Secrets Management Tool: Don’t hardcode secrets. Instead, use something like HashiCorp Vault, AWS Secrets Manager, or Doppler to securely store and inject secrets at runtime.
- Harden CI/CD Environment: Treat your CI/CD environment like production. Turn on audit logging, network segmentation, 2FA, and patch often.
- Shift Left on Security: Implement security scanning early in the pipeline: static code scanning (SAST), dependency scanning, secret discovery, and container scanning. Don’t let vulnerabilities go all the way to prod.
- Monitor for Abnormalities: Monitor behavior and apply anomaly detection to flag suspicious behavior within your pipeline. As noted in IBM’s 2024 Cost of a Data Breach Report, the worldwide average per-breach cost for a data breach in 2024 was $4.88 million. This is a 10% increase from last year, the highest level ever reported, and represents the increasing financial effect of cybersecurity breaches on organizations worldwide.
Should You DIY Security or Hire Cyber Expert Help?
Software environments today are too complex to be secured with basic configurations. Even seasoned DevOps teams typically lack end-to-end cybersecurity knowledge.
That’s where the worth of having a cyber security expert for hire becomes clear. They don’t merely introduce tooling, but context; threat modeling, secure architecture, and practical experience with vulnerabilities in high-speed CI/CD pipelines.
If your codebase is expanding and you’re dealing with multi-cloud, microservices, or high release cadences, hire cyber expert assistance, even if only for a strategic review.

Let’s Sum Up
Your CI/CD pipeline is strong, but if you don’t lock it down, it’s a loaded gun aimed at your own infrastructure. From hijacked credentials and malware to untrusted dependencies and over-permissioned executors, attackers today are no longer attacking your app — they’re attacking the system that builds and deploys it.
Don’t leave your pipeline open wide. Shift left. Lock down secrets. And when in doubt, bring in a cyber security expert for hire to help you audit and lock down the build chain before it is your weakest link. As in contemporary software, compromise doesn’t begin at production, it begins with code.
