7-Eleven confirms ShinyHunters breach of 600,000+ Salesforce franchise-application records — same campaign as Instructure, Vimeo, Wynn Resorts, Vercel, Medtronic
7-Eleven, Inc. confirmed on 2026-05-18 that an unauthorised third party accessed systems storing franchisee documents on 2026-04-08, in a breach claimed by ShinyHunters on or around 2026-04-17 (SecurityWeek, 2026-05-18; Security Affairs, 2026-05-18). ShinyHunters listed over 600,000 Salesforce CRM records covering personal and corporate data from franchise applications, initially demanding a ransom with a 2026-04-21 deadline and then offering the data for sale at $250,000 on a hacker forum. 7-Eleven filed a Maine Attorney General notification dated 2026-05-01 confirming 24 months of IDX identity-theft protection for affected individuals (Maine AG breach notification, 2026-05-01). The Maine filing lists only 2 Maine residents but the ShinyHunters claim covers 600,000+ records globally. SecurityWeek attributes the broader campaign — Instructure (Canvas), Vimeo, Wynn Resorts (21,000 employees), Vercel and Medtronic among confirmed co-victims — not to Salesforce-product vulnerabilities but to phishing, third-party-integration abuse, and customer-side misconfiguration of Salesforce Connected Apps.
Why it matters to us: ShinyHunters is the same actor that hit Instructure last week, with the broader Salesforce-targeting campaign continuing across sectors. The campaign vector is identity-side rather than Salesforce-product-side — Connected App OAuth grant abuse, phishing of admin sessions, mis-scoped third-party SaaS integrations. EU/CH public-sector and finance tenants using Salesforce for partner / supplier / case-management data should audit Connected App OAuth grants (particularly to third-party AI SaaS integrations), enable Salesforce Event Monitoring with alerts on bulk Report Export events and high-volume SOQL API calls, enforce IP-range / Trusted-IP session policies, and consider Salesforce Shield field-level encryption for PII.

7-Eleven confirmed a breach after ShinyHunters claimed theft of over 600,000 Salesforce records and franchisee data
The intrusions resulted from phishing, abuse of third-party integrations, or misconfigurations, rather than vulnerabilities in Salesforce products
ATT&CK mapping
3 techniques mapped from the cited reporting · MITRE ATT&CK v19.2
Initial Access TA0001
T1078.004Valid Accounts: Cloud Accounts
Valid accounts in cloud environments may allow adversaries to perform actions to achieve Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Cloud accounts are those created and configured by an organization for use by users, remote support, services, or for administration of resources within a cloud service provider or SaaS application. Cloud Accounts can exist solely in the cloud; alternatively, they may be hybrid-joined between on-premises systems and the cloud through syncing or federation with other identity sources such as Windows Active Directory.
Persistence TA0003
T1078.004Valid Accounts: Cloud Accounts
Valid accounts in cloud environments may allow adversaries to perform actions to achieve Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Cloud accounts are those created and configured by an organization for use by users, remote support, services, or for administration of resources within a cloud service provider or SaaS application. Cloud Accounts can exist solely in the cloud; alternatively, they may be hybrid-joined between on-premises systems and the cloud through syncing or federation with other identity sources such as Windows Active Directory.
Privilege Escalation TA0004
T1078.004Valid Accounts: Cloud Accounts
Valid accounts in cloud environments may allow adversaries to perform actions to achieve Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Cloud accounts are those created and configured by an organization for use by users, remote support, services, or for administration of resources within a cloud service provider or SaaS application.

Stealth TA0005
T1078.004Valid Accounts: Cloud Accounts
Valid accounts in cloud environments may allow adversaries to perform actions to achieve Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Cloud accounts are those created and configured by an organization for use by users, remote support, services, or for administration of resources within a cloud service provider or SaaS application.

Collection TA0009
T1530Data from Cloud Storage
Adversaries may access data from cloud storage.
Exfiltration TA0010
T1567.002Exfiltration Over Web Service: Exfiltration to Cloud Storage
Adversaries may exfiltrate data to a cloud storage service rather than over their primary command and control channel. Cloud storage services allow for the storage, edit, and retrieval of data from a remote cloud storage server over the Internet.
