Full Incident Analysis Transcript
In this Rankiteo incident briefing, we review the Coder breach identified under incident ID COD1788855826.
The analysis begins with a detailed overview of Coder's information like the linkedin page: https://www.linkedin.com/company/coder, the number of followers: 8, the industry type: Technology, Information and Internet and the number of employees: 1 employees
After the initial compromise, the video explains how Rankiteo's incident engine converts technical details into a normalized incident score. The incident score before the incident was 771 and after the incident was 740 with a difference of -31 which is could be a good indicator of the severity and impact of the incident.
In the next step of the video, we will analyze in more details the incident and the impact it had on Coder and their customers.
On 31 August 2026, Coder disclosed Supply-Chain Attack issues under the banner "Critical Supply-Chain Attack on Coder’s Terraform Registry Exposes Cloud Credentials".
On August 31, 2026, Coder disclosed a security breach in its Terraform module registry, where attackers hijacked infrastructure to distribute malicious packages designed to steal credentials.
The disruption is felt across the environment, affecting Terraform module registry, Coder workspace templates, provisioner environments, and exposing Environment variables, OIDC tokens, SSH keys, temporary authentication credentials, database credentials, external authentication provider settings, cloud API keys, CI/CD secrets.
In response, moved swiftly to contain the threat with measures like Released patched versions (2.37.0, 2.36.4, 2.35.7, 2.34.9), advised removal of cached modules downloaded during the attack window, and began remediation that includes Updated to latest secure versions, rotated all potentially exposed credentials, while recovery efforts such as Audit logs for connections to *coder-infra[.]com* or *data.external.telemetry* string continue, and stakeholders are being briefed through Public disclosure and advisory to users.
The case underscores how teams are taking away lessons such as Growing risk of supply-chain attacks in infrastructure-as-code workflows, need to scrutinize trusted sources for similar threats, and recommending next steps like Remove cached modules from attack window, update to latest secure versions, audit logs for malicious activity, rotate all potentially exposed credentials, with advisories going out to stakeholders covering Advisory to remove cached modules, update to patched versions, rotate credentials, and audit logs.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
MITRE ATT&CK® Correlation Analysis
Rankiteo's analysis has identified several MITRE ATT&CK tactics and techniques associated with this incident, each with varying levels of confidence based on available evidence. Under the Initial Access tactic, the analysis identified Supply Chain Compromise: Compromise Software Supply Chain (T1195.002) with high confidence (90%), with evidence including hijacked infrastructure to distribute malicious packages, and tampered Terraform modules containing credential-stealing malware and Trusted Relationship (T1199) with moderate to high confidence (80%), supported by evidence indicating attackers hijacked Coder’s Terraform module registry, a trusted source. Under the Execution tactic, the analysis identified Exploitation for Client Execution (T1203) with moderate to high confidence (80%), supported by evidence indicating malicious code embedded in *data.external.telemetry* block executed *dlp-docker.sh* script and Command and Scripting Interpreter: Unix Shell (T1059.004) with high confidence (90%), supported by evidence indicating executed a script (*dlp-docker.sh*) to exfiltrate secrets. Under the Credential Access tactic, the analysis identified Unsecured Credentials: Credentials In Files (T1552.001) with high confidence (90%), supported by evidence indicating stole environment variables, OIDC tokens, SSH keys, temporary authentication credentials and Unsecured Credentials: Cloud Instance Metadata API (T1552.005) with moderate to high confidence (70%), supported by evidence indicating potential exposure of database credentials, cloud API keys, CI/CD secrets. Under the Collection tactic, the analysis identified Data from Local System (T1005) with high confidence (90%), supported by evidence indicating accessed local secrets in provisioner environments and Data from Code Repositories: Code Repositories (T1213.003) with moderate to high confidence (80%), supported by evidence indicating tampered Terraform modules hosted on hijacked registry. Under the Exfiltration tactic, the analysis identified Exfiltration Over C2 Channel (T1041) with high confidence (90%), supported by evidence indicating exfiltrated secrets to *coder-infra.com* (199.91.220.205). Under the Defense Evasion tactic, the analysis identified Subvert Trust Controls: Code Signing (T1553.002) with moderate to high confidence (80%), supported by evidence indicating malicious Terraform modules distributed via trusted registry and Valid Accounts: Cloud Accounts (T1078.004) with moderate to high confidence (70%), supported by evidence indicating unauthorized modifications to Cloudflare configuration. Under the Command and Control tactic, the analysis identified Application Layer Protocol: Web Protocols (T1071.001) with moderate to high confidence (80%), supported by evidence indicating exfiltrated data to *coder-infra.com* (lookalike domain). These correlations help security teams understand the attack chain and develop appropriate defensive measures based on the observed tactics and techniques.
