Indicators of a Malicious Code Attack: What You Need to Know
Malicious code attacks are growing rapidly, costing businesses millions every year. According to a recent study, the average cost of a data breach has soared to $4.45 million in 2023. Early detection of indicators of a malicious code attack is crucial for stopping these threats before they cause serious damage.
Attackers often exploit open-source vulnerabilities, leaked secrets, and misconfigured infrastructure to deploy malicious code. For example, the Meow Bot attack targeted thousands of unsecured databases, wiping data without warning. These incidents highlight the need for proactive security measures.
Xygeni’s automated security platform helps teams detect, prioritize, and remediate threats—ensuring your systems stay protected.
How to Spot Indicators of a Malicious Code Attack
Suspicious Behavior in Open-Source Dependencies
Open-source components are key to modern development, but they are also a common entry point for malicious code. For example, the NoxPlayer supply chain attack compromised software updates to deliver malware. In many cases, developers miss these changes until it’s too late.
Common Indicators:
- Outbound connections to unfamiliar domains from previously trusted libraries.
- Dependencies that request elevated permissions without a clear reason.
- A data processing component suddenly accessing the file system, which it never did before.
How Xygeni Helps:
- SCA detects and monitors dependencies for changes and known vulnerabilities.
- EPSS prioritizes vulnerabilities based on their real-world risk.
- Automated patch suggestions ensure quick remediation.
Secrets Exposure: A Major Security Risk
Leaked credentials are among the most serious indicators of a malicious code attack. For instance, in the Codecov breach, attackers accessed cloud services by stealing API keys from CI/CD environments. As a result, they gained unauthorized access and moved laterally across multiple systems, expanding their reach. Moreover, this kind of breach can expose sensitive data and lead to long-term security risks.
Warning Signs:
- Hardcoded secrets or credentials in repositories.
- Unexpected access attempts from external IPs.
- Increased API activity without corresponding application changes.
Xygeni Detects and Secures Secrets:
- Real-time scanning for secrets across repositories.
- Immediate alerts and automatic remediation.
- Integration with secret management tools like AWS Secrets Manager.

Misconfigured IaC: A Hidden Entry Point for Malicious Code
IaC misconfigurations can also expose systems to highly targeted attacks, including those similar to the Polyfill attack. For example, overly permissive IAM roles might allow attackers to inject malicious scripts directly into cloud services. In addition, unrestricted network policies may leave your infrastructure vulnerable to remote code execution.
Common IaC Misconfigurations:
- Overly Permissive IAM Roles: An IAM role with
*permissions allows attackers to access far more resources than needed. - Unrestricted Network Policies: A security group allowing inbound traffic from any IP address on ports 80/443 opens your web servers to attacks.
- Lack of Resource Isolation: Without proper segmentation, attackers can jump between services and expand their reach.
How Xygeni Prevents IaC Misconfigurations:
- Scans IaC templates for vulnerabilities before deployment.
- Enforces network and IAM policies to follow least privilege principles.
- Provides real-time remediation suggestions to developers.
EPSS: Prioritizing the Most Critical Indicators of a Malicious Code Attack
Exploit Prediction Scoring System (EPSS) ranks vulnerabilities based on their likelihood of being exploited within the next 30 days. Unlike CVSS, which focuses on severity, EPSS predicts real-world risks. Teams can focus on high-risk vulnerabilities instead of wasting time on minor issues.
Xygeni Uses EPSS To:
- Reduce false positives and alert fatigue.
- Prioritize vulnerabilities that attackers are actively targeting.
- Focus remediation on the most critical issues.
Why Choose Xygeni? The Benefits You Gain
Instead of listing features, let’s focus on what Xygeni does for your security:
- Reduce Supply Chain Risk: Comprehensive SCA scans all dependencies and generates a Software Bill of Materials (SBOM).
- Prevent Secrets Exposure: Xygeni catches secrets before they are committed and integrates with your vault solutions.
- Secure Your Infrastructure: Proactively detect and fix IaC misconfigurations to prevent attackers from exploiting them.
- Focus on Real Threats: EPSS-based prioritization ensures your team works on the most dangerous vulnerabilities first.
- Speed Up Remediation: Automated remediation reduces manual work and improves your response time.
Addressing Common Concerns
What if We Already Use Other Security Tools?
In many cases, security teams already have several tools in place. However, Xygeni doesn’t replace your current tools—it enhances them. By integrating seamlessly with CI/CD pipelines and security platforms, it ensures consistent protection at every stage of the development lifecycle. In other words, think of Xygeni as a security multiplier that boosts the effectiveness of your existing setup.
Stay Ahead of Malicious Code Attacks
Malicious code attacks are costly and increasingly common, but with early detection, teams can stop threats before they escalate. By focusing on automation, prioritized remediation, and proactive monitoring, security teams not only reduce risk but also respond faster. Moreover, automation allows developers to stay productive while improving security across the board.
Xygeni simplifies security, helping teams detect, prioritize, and remediate vulnerabilities quickly.
