Overview

Threat actors are increasingly weaponizing cloud infrastructure, exploiting the trust organizations place in their Amazon Web Services (AWS) environments. The group known as Crimson Collective exemplifies this trend, using stolen or exposed AWS access keys to create new administrator accounts, reset database passwords, and steal massive volumes of data through legitimate API actions without deploying a single piece of malware. In a recent high-profile case, the group claimed responsibility for stealing over 570 gigabytes of internal GitLab data from Red Hat, later leveraging the company’s own cloud email service to deliver ransom demands directly from within its AWS environment. This approach, known as “cloud-native extortion,” represents a growing shift from endpoint ransomware toward attacks that exploit built-in cloud functionality rather than vulnerabilities or exploits. Because these operations rely on normal administrative actions, creating snapshots, exporting data, and sending messages, they often evade traditional security monitoring and leave limited forensic evidence. The result is a fast-moving, low-visibility form of data theft that can compromise entire cloud estates in hours. Organizations that depend heavily on long-lived credentials, permissive IAM policies, or unmonitored export capabilities face heightened exposure and must act now to enforce least-privilege access, continuous monitoring, and tighter identity governance to reduce the likelihood of similar breaches.

Key Findings:

  • Crimson Collective’s operations demonstrate a fundamental evolution in cyber extortion; attackers now weaponize AWS’s own administrative tools and APIs to steal or encrypt data entirely within the cloud environment, eliminating the need for malware or external infrastructure.
  • These attacks exploit weaknesses in identity governance, using long-lived credentials, excessive permissions, and unmonitored exports to gain full control of cloud accounts while appearing as legitimate activity.
  • Logging and monitoring gaps across AWS regions allow adversaries to disable visibility, manipulate configurations, and erase forensic traces, leaving defenders blind during and after an intrusion.
  • The Red Hat breach illustrates how ransom delivery through internal AWS services, such as SES, amplifies reputational and operational impact by turning trusted systems into extortion channels.
  • Immediate action: Focus on eliminating long-lived credentials, enforcing MFA and least-privilege roles, and restricting high-risk API functions like snapshot exports and SSE-C encryption. Organizations must also ensure continuous, immutable logging across all regions and disable or tightly govern services such as SES that can be weaponized for ransom delivery.

1.0 Threat Overview

1.1 Historical Context

The current wave of AWS-focused extortion campaigns reflects a clear shift in how cybercriminals exploit the cloud. Early cloud incidents were largely opportunistic, where attackers scanned for misconfigured storage buckets or public keys left in source code. Those attacks typically aimed for data exposure or crypto mining, not ransom. That changed in late 2024 and early 2025 when threat actors began realizing they could weaponize AWS’s own management features for financial gain. The first sign of this evolution appeared with Codefinger, a group that encrypted Amazon S3 data using AWS’s built-in Server-Side Encryption with Customer-Provided Keys (SSE-C). Instead of deploying malware, they used legitimate API calls to lock down victims’ files and demand payment for the decryption keys. Within months, Crimson Collective expanded on that approach, pivoting from encryption to data theft and extortion by exfiltrating information through snapshots and exports while sending ransom messages from inside the victim’s cloud account. This evolution signals the rise of cloud-native extortion, where attackers no longer need custom code or zero-day exploits. The Red Hat incident, where Crimson Collective claimed to have stolen 570 gigabytes of source code and project data, demonstrates that these attacks have moved from theory to reality and that cloud infrastructure is now the primary battlefield.

1.2 Technique Breakdown

Attackers are exploiting valid AWS credentials and normal management APIs to move quickly and quietly inside cloud accounts. Rather than planting malware, they perform sequences of legitimate actions that together produce the same result: bulk access to data, rapid staging for exfiltration, and convincing extortion messages sent from the victim’s own environment. This method leaves few endpoint traces and can complete in hours when logging and guardrails are weak.

2.0 Preconditions for Exploitation

These are the specific weaknesses attackers rely on to turn ordinary cloud functions into an extortion pipeline. When one or more of these conditions exist, the risk of rapid, high-impact data theft rises dramatically.If any of these conditions are present, treat the account as high risk and prioritize immediate controls such as rotating credentials, tightening permissions, pausing snapshot/export capabilities, and verifying multi-region logging.

AWS Security Weaknesses
Long-Lived or Exposed Credentials
Critical Risk
API keys and credentials that last for months or are accidentally committed to public code repositories make it trivial for attackers to log in as legitimate users.
Exploitation Impact
Attackers scan public repositories and data leaks for exposed credentials, gaining immediate authenticated access without requiring exploitation of vulnerabilities.
Mitigation Strategy
Implement credential rotation policies, enforce short-lived tokens, use secret scanning tools, and mandate credential vaulting for all API keys.
API Keys Credential Exposure Code Repositories Credential Rotation
Over-Privileged Identities
Critical Risk
Users, service accounts, or roles that have broad permissions allow an attacker who gains access to move from read-only actions to full control without additional obstacles.
Exploitation Impact

Cloud-Native Extortion Model
Crimson Collective represents a new class of cloud-native extortion actors that rely solely on identity abuse and control-plane manipulation. Their campaigns require no malware, exploit no zero-days, and rely entirely on mismanaged credentials and permissive IAM policies. The speed, stealth, and use of legitimate AWS tools make them a high-priority threat to any organization with incomplete cloud governance.
No Malware No Zero-Days Legitimate APIs Only Identity-Based

4.0 Risk and Impact

Crimson Collective represents a critical escalation in how threat actors target cloud infrastructure. By exploiting valid AWS credentials and legitimate management APIs, they bypass traditional endpoint security and perimeter defenses entirely. The result is a form of extortion that operates within trusted cloud environments, using the victim’s own infrastructure to stage, steal, and ransom data. This method eliminates the need for malware, shortens attack timelines to hours, and leaves few traces if logging is incomplete. The primary risk is total loss of control over cloud-hosted data and systems, without a single server being “hacked” in the traditional sense.

For organizations with long-lived credentials, over-privileged IAM roles, or incomplete audit coverage, this threat poses a high likelihood of rapid data loss, business disruption, and reputational damage. Financial impact extends beyond ransom payments to include regulatory penalties, breach disclosure costs, and operational downtime. The reputational fallout from ransom messages sent through internal AWS accounts amplifies the erosion of public trust. Ultimately, the Crimson Collective campaign highlights that the weakest point in modern cloud security is not software vulnerability, but identity and governance failure.

5.0 Recommendations for Mitigation

5.1 Identity and Access Governance

  • Replace static IAM keys entirely with ephemeral tokens issued via AWS Security Token Service (STS) and set maximum session durations to under one hour. This breaks attacker persistence without requiring continuous credential audits.
  • Enforce organization-level SCPs that disable IAM policy modification outside a single administrative account, ensuring even compromised admins cannot escalate privileges laterally.
  • Integrate GitHub Advanced Security or TruffleHog scanning hooks directly into CI/CD pipelines to detect AWS key leaks in real time before deployment.
  • Deploy IAM Access Analyzer in continuous mode and auto-quarantine any role or key that suddenly gains new cross-account permissions.

5.2 Control-Plane Hardening

  • Configure CloudFormation StackSets with restrictive service control boundaries to prevent ad-hoc resource creation, such as snapshots or exports, outside of declared infrastructure templates.
  • Create API throttling policies for sensitive operations (snapshot creation, key management, export tasks) — unusual frequency becomes an immediate detection trigger.
  • Deploy region-deny policies: restrict data export to specific approved AWS regions; any cross-region data movement should generate a high-priority alert.
  • Enable automatic CloudTrail integrity validation using digest files — this detects tampering even if logs are modified or deleted.

5.3 Snapshot and Export Safeguards

  • Implement event-driven response playbooks: when a new snapshot or export task is created outside defined change windows, automation suspends the AWS account’s network egress until validated.
  • Require that all snapshot destinations reference KMS keys owned by the organization, not by individual IAM users.
  • Deploy AWS Macie to classify sensitive data and alert when those datasets appear in newly created or unrecognized S3 buckets.
  • Introduce snapshot immutability windows (e.g., 24–48 hours) during which snapshots cannot be shared or deleted — this delays exfiltration and increases response time.

5.4 Logging and Forensic Integrity

  • Store CloudTrail and Config logs in a dedicated security account with a separate root of trust, using AWS Organizations’ delegated admin feature; this prevents log tampering even if production accounts are compromised.
  • Implement real-time log streaming to immutable external storage (e.g., S3 with Object Lock or third-party archival) for redundant retention and tamper evidence.
  • Correlate API anomalies (IAM changes, snapshot exports, SES usage) through custom Security Hub insights — these combinations uniquely signal this threat’s activity chain.
  • Configure AWS Detective or your SIEM to alert on “first-time-seen” administrative API calls per user, an indicator of credential misuse.

5.5 SES and Communication Control

  • Use AWS Organizations SCPs to disable SES in all but pre-approved accounts — don’t rely on IAM policies alone.
  • Implement CloudWatch alarms for SES throughput spikes exceeding baseline thresholds, with automated suspension of email sending via API if triggered.
  • Configure DKIM and DMARC record checks to external validation tools that alert when AWS-originated emails deviate from corporate domains — a strong detection for internal ransom note delivery.

5.6 Strategic Actions for Executives

  • Commission an identity compromise simulation using a red team or cloud security provider to test whether your AWS governance can detect a Codefinger/Crimson-style intrusion.
  • Mandate that cloud risk reporting include credential exposure counts, privilege growth rate, and logging coverage ratios as key performance indicators.
  • Require MSSPs or incident responders under retainer to demonstrate response playbooks specific to AWS credential abuse, not just endpoint ransomware.
  • Allocate budget toward automated IAM hygiene enforcement tools — manual policy audits can’t keep pace with the attack speed of cloud-native extortion.

6.0 Hunter Insights

Crimson Collective’s recent campaign marks a transformative escalation in cloud-based cyber extortion, targeting AWS environments using stolen or leaked credentials rather than malware or exploits. By abusing legitimate AWS management APIs, including those for account creation, privilege escalation, data snapshotting, and exfiltration, Crimson Collective rapidly steals massive datasets and delivers ransom demands from within the victim’s infrastructure itself. This method allows the group to evade traditional endpoint defenses, erase forensic evidence, and bypass classic network-based detection by blending entirely with normal administrative operations.

Looking ahead, this "cloud-native extortion" technique is likely to proliferate, with more threat actors turning their attention to identity- and control-plane abuse as cloud adoption deepens across organizations. As attackers recognize the value of targeting core identity weaknesses, security gaps in IAM governance, long-lived credentials, and insufficient multi-region logging will continue to expose enterprises to rapid, large-scale data theft and extortion. Without urgent advances in identity hygiene, privileged account management, and continuous anomaly detection, enterprises can expect both the frequency and impact of such attacks to grow—potentially compromising entire cloud estates within hours and escalating the operational, financial, and reputational risks of cloud operations.
