Security is an exercise in managing risk. Reviewing the common root causes of security incidents is an effective way to guide prioritized remediation efforts.
This repository seeks to index all publicly disclosed AWS customer security incidents with a known root cause. It will exclude incidents involving exposed data stores (e.g S3 bucket leaks, exposed managed or hosted databases). Those incidents are already well understood, and examples can be found cataloged in places like nagwww's s3-leaks repo, upguard's reports, hackmeggedon's annual rollup reports (2022) and Corey Quinn's LWIAWS S3 Bucket Negligence Award.
It also excludes incidents impacting individuals, such as the periodic reports of cryptomining due to compromised credentials. 1 2 3
This repository is in no way intended as a criticism of the listed companies. In the spirit of blameless postmortems 1, our goal is to learn from incidents without an atmosphere of blame.

| AWS: 2022 re:Inforce session on ransomware h/t Rich Mogull | ransomware is a common problem for AWS customers, stemming from two common exploit vectors: A traditional ransomware attack against instances in AWS. The attacker compromises an instance (often via phishing a user/admin, not always direct compromise), then installs their malware to encrypt the data and spread to other reachable instances. This is really no different than ransomware in a data center since it doesn’t involve anything cloud-specific. The attacker copies data out of an S3 bucket and then deletes the original data. This is the most commonly seen cloud native ransomware on AWS. |

| Datadog: State of AWS Security 2022 | N/A |
| ENISA Threat Landscape 2022 | Cybercriminals target cloud services mostly in the following ways. \n * Exploiting cloud vulnerabilities: virtualisation infrastructure has been increasingly targeted (e.g. VMWare vSphere and ESXi platforms) by cybercriminals and especially by ransomware groups. • Using cloud services for hosting their infrastructure: cybercriminals take advantage of the highly scalable and reliable cloud infrastructure and use legitimate cloud services to bypass security controls by blending into normal network traffic. • Targeting cloud credentials: cybercriminals use social engineering attacks to harvest credentials for cloud services (e.g. Microsoft Office 365, Okta, etc.). • Exploiting misconfigured image containers cybercriminals increasingly target poorly configured Docker containers and Kubernetes clusters. • Targeting cloud instances for cryptomining (e.g. TeamTNT group): security researchers have identified a cloud-focused toolset from the TeamTNT group. • Targeting cloud infrastructure (e.g. Azure AD), cloud application programming interfaces (APIs), and cloud-hosted backups by ransomware groups to infiltrate cloud environments and increase impact. |

Server-side request forgery is a class of attack that is not cloud or AWS specific. However, the existence of cloud metadata services, such as IMDS in AWS, have historically allowed for a substantial straightforward impact when SSRF is achieved on a cloud hosted application. For that reason, we include this list of SSRF attacks against AWS environments.
