Matching passage: T1530 Data from Cloud Storage. Tactics: collection. Description: Adversaries may access data from cloud storage. Many IaaS providers offer solutions for online data object storage such as Amazon S3, Azure Storage, and Google Cloud Storage. Similarly, SaaS enterprise platforms such as Office 365 and Google Workspace provide cloud-based document storage to users through services such as OneDrive and Google Drive, while SaaS application providers such as Slack, Confluence, Salesforce, and Dropbox may provide cloud storage solutions as a peripheral or primary use case of their platform. In some cases, as with IaaS-based cloud storage, there exists no overarching application (such as SQL or Elasticsearch) with which to interact with the stored objects: instead, data from these solutions is retrieved directly though the [Cloud API](https://attack.mitre.org/techniques/T1059/009). In SaaS applications, adversaries may be able to collect this data directly from APIs or backend cloud storage objects, rather than through their front-end application or interface (i.e., [Data from Information Repositories](https://attack.mitre.org/techniques/T1213)). Adversaries may collect sensitive data from these cloud storage solutions. Providers typically offer security guides to help end users configure systems, though misconfigurations are a common problem.(Citation: Amazon S3 Security, 2019)(Citation: Microsoft Azure Storage Security, 2019)(Citation: Google Cloud Storage Best Practices, 2019) There have been numerous incidents where cloud storage has been improperly secured, typically by unintentionally allowing public access to unauthenticated users, overly-broad access by all users, or even access for any anonymous person outside the control of the Identity Access Management system without even needing basic user permissions. This open access may expose various types of sensitive data, such as credit cards, personally identifiable information, or medical records.(Citation: Trend Micro S3 Exposed PII, 2017)(Citation: Wired Magecart S3 Buckets, 2019)(
Near-miss passage: T1213.005 Messaging Applications. Tactics: collection. Description: Adversaries may leverage chat and messaging applications, such as Microsoft Teams, Google Chat, and Slack, to mine valuable information. The following is a brief list of example information that may hold potential value to an adversary and may also be found on messaging applications: * Testing / development credentials (i.e., [Chat Messages](https://attack.mitre.org/techniques/T1552/008)) * Source code snippets * Links to network shares and other internal resources * Proprietary data(Citation: Guardian Grand Theft Auto Leak 2022) * Discussions about ongoing incident response efforts(Citation: SC Magazine Ragnar Locker 2021)(Citation: Microsoft DEV-0537) In addition to exfiltrating data from messaging applications, adversaries may leverage data from chat messages in order to improve their targeting - for example, by learning more about an environment or evading ongoing incident response efforts.(Citation: Sentinel Labs NullBulge 2024)(Citation: Permiso Scattered Spider 2023)
