T1586.003: Cloud Accounts
Adversaries may compromise cloud accounts that can be used during targeting. Adversaries can use compromised cloud accounts to further their operations, including leveraging cloud storage services such as Dropbox, Microsoft OneDrive, or AWS S3 buckets for Exfiltration to Cloud Storage or to Upload Tools. Cloud accounts can also be used in the acquisition of infrastructure, such as Virtual Private Servers or Serverless infrastructure. Additionally, cloud-based messaging services such as Twilio, SendGrid, AWS End User Messaging, AWS SNS (Simple Notification Service), or AWS SES (Simple Email Service) may be leveraged for spam or Phishing.[1][2] Compromising cloud accounts may allow adversaries to develop sophisticated capabilities without managing their own servers.[3]
A variety of methods exist for compromising cloud accounts, such as gathering credentials via Phishing for Information, purchasing credentials from third-party sites, conducting Password Spraying attacks, or attempting to Steal Application Access Tokens.[4] Prior to compromising cloud accounts, adversaries may conduct Reconnaissance to inform decisions about which accounts to compromise to further their operation. In some cases, adversaries may target privileged service provider accounts with the intent of leveraging a Trusted Relationship between service providers and their customers.[4]
Security context for executives and security teams

Executive priority
T1586.003: Cloud Accounts is an official MITRE ATT&CK technique. Glexia treats it as defensive behavior context for prioritizing monitoring, control validation, and response planning without using the object by itself as an attribution claim.
Technical view
Security teams should validate T1586.003: Cloud Accounts by reviewing the official ATT&CK relationships, mapped tactics (resource-development), supported platforms (PRE), and available local telemetry before making detection or mitigation decisions.
Likely telemetry
- Official ATT&CK relationships and object metadata
Detection direction
- Validate whether T1586.003: Cloud Accounts appears in your detection coverage and tabletop scenarios.
- Use the object to align executive risk language with SOC, incident response, and detection engineering work.
- Do not treat ATT&CK relationship context as attribution without corroborating evidence.
Mitigation priorities
- Map the object to existing controls and identify missing telemetry or response ownership.
- Prioritize mitigations that reduce exposure on the listed platforms and tactics.
- Review adjacent ATT&CK relationships before changing policy, detections, or reporting language.
Additional notes and limits
Baseline Glexia take generated from the official MITRE ATT&CK STIX object, source hash, tactics, platforms, and detection fields. It is safe to replace with a richer model-generated take for the same source hash later.
This baseline take is source-grounded and schema-validated, but it does not include environment-specific telemetry, incident evidence, or threat-intelligence corroboration.

Groups, software, and campaigns
G0016: APT29
APT29 is threat group that has been attributed to Russia's Foreign Intelligence Service (SVR).[1][2] They have operated since at least 2008, often targeting government networks in Europe and NATO member countries, research institutes, and think tanks. APT29 reportedly compromised the Democratic National Committee starting in the summer of 2015.[3][4][5][6]
In April 2021, the US and UK governments attributed the SolarWinds Compromise to the SVR; public statements included citations to APT29, Cozy Bear, and The Dukes.[7][8] Industry reporting also referred to the actors involved in this campaign as UNC2452, NOBELIUM, StellarParticle, Dark Halo, and SolarStorm.[9][10][11][12][13][14]
G0099: APT-C-36
APT-C-36 is a suspected South American threat group that has engaged in espionage and financially motivated operations since at least 2018. APT-C-36 has targeted government institutions and entities in the financial, energy, and professional manufacturing sectors across Colombia and other Latin American countries.[1][2][3][4]
C0040: APT41 DUST
APT41 DUST was conducted by APT41 from 2023 to July 2024 against entities in Europe, Asia, and the Middle East. APT41 DUST targeted sectors such as shipping, logistics, and media for information gathering purposes. APT41 used previously-observed malware such as DUSTPAN as well as newly observed tools such as DUSTTRAP in APT41 DUST.[1]
