The Salesforce Supply Chain Crisis: How Qantas’s 5.7M Data Leak Exposes All Integrated Global Companies

Attackers didn’t need to break the core cloud. They abused the integrations around it—call-center platforms, connected apps, OAuth tokens, and partner access. The Qantas breach impacting ~5.7 million customers is a wake-up call for every enterprise wired into Salesforce or similar CRMs. This briefing maps the attack chain, shows where you’re exposed, and gives you a 30-60-90 plan to fix it.CyberDudeBivash Ecosystem:Apps & Services · CyberBivash (Threat Intel) · CryptoBivash · News Portal · Subscribe: ThreatWire

TL;DR — What Just Happened & Why It’s Your Problem

5.7M Qantas records leaked: personal data published after extortion tied to Salesforce customer ecosystems and a third-party servicing platform.
Not core-cloud break; integration abuse: attackers targeted customer-side instances, connected apps, vendors, and call-center platforms—then exfiltrated CRM data.
Global blast radius: multiple big brands reportedly affected; any org integrated to CRM with liberal OAuth scopes or partner access is at risk.

1) Attack Chain: How Integrations Became the Backdoor

Initial Access: Phishing/social engineering of support/vendor users; or token reuse in third-party contact-center/RevOps tools linked to Salesforce.
Privilege via OAuth: Over-permissive “Connected Apps” granted api, refresh_token, full, read/write on objects (Contact, Case, Lead).
Bulk Exfiltration: API-driven export (Bulk, REST, SOQL) from a partner IP or app; staging in external storage; extortion.
Publication & Fallout: Data posted after unpaid ransom; frequent-flyer data fuels phishing & account takeover campaigns.

2) Exposure Map: Where Your Salesforce Data Leaks

Call-center/outsourcers: mirrored CRM views, CSV exports, and agent desktops with cached tokens.
Connected Apps & Marketplaces: marketing/chat/bot tools with broad scopes or weak app-review.
RevOps syncs: data warehouses, BI, CDP pipelines with long-lived refresh tokens.
Over-shared roles: system administrators in partner orgs; SSO exceptions; IP allowlist gaps.
Shadow exports: reports scheduled to email/SFTP; unmanaged cloud buckets.

3) Detections — SIEM/CASB/CRM Audit (Pseudocode)

OAuth & Connected Apps

# New high-privilege OAuth consent on CRM
AuditLogs
| where AppPlatform == "Salesforce"
| where Event in ("ConnectedAppAuthorized","OAuthTokenIssued")
| where Scopes has_any ("full","refresh_token","api")
| summarize count() by AppName, User, Scopes, bin(Time, 1h)

Bulk/API Exports

# Abnormal REST/Bulk exports by non-service account
SalesforceApi
| where Operation in ("QUERY","BULK_EXPORT")
| summarize rows_out = sum(Rows) by User, SourceIP, bin(Time, 15m)
| where rows_out > 50000 and User !in ("svc_export","etl_bot")

Exfil via Cloud/Email

# Transcript/CSV/JSON to external domains
CASBHttp
| where Url has_any (".csv",".json",".zip")
| where DestinationDomain !endswith "yourcompany.com"
| summarize Bytes = sum(BytesSent) by User, DestinationDomain, bin(Time, 1h)
| where Bytes > 50MB

4) Mitigations — Policies, Scopes, Network & Vendor Controls

Default-Deny Connected Apps: Turn on admin consent workflow; allowlist apps; strip full/refresh_token unless justified; rotate secrets quarterly.
Partner Zero-Trust: Separate partner roles/profiles; IP allowlists; device posture rules; session timeouts; no shared accounts.
Export Guardrails: DLP on CSV/ZIP; quarantine external shares; watermark scheduled reports; disable email-to-CSV for sensitive objects.
Least-Privilege Objects: Create read-only views for vendors; deny access to PII fields not needed (DoB, loyalty balances, addresses).
High-Risk Object Watchlist: Contacts, Cases with PII, Loyalty/FFP tables, Bookings; set anomaly thresholds per object.
IR/Extortion Playbook: Evidence preservation, takedown/LE coordination, customer comms, phishing countermeasures, token/secret rotation.

5) CISO 30-60-90 Day Plan

Day 0-30 — Contain & Inventory

Inventory all Connected Apps & integrations; revoke unused; rotate secrets/tokens.
Lock partner access behind IP allowlists and device checks; disable legacy report emails.
Stand up detections above; block large external CSV/ZIP egress in CASB.

Day 31-60 — Harden & Monitor

Implement admin-consent workflow; tier scopes (api w/o refresh_token by default).
PII field-level security review; mask where possible; tokenize optional fields.
Tabletop “CRM exfil & extortion” with Legal/Comms; prepare customer-notification templates.

Day 61-90 — Assure & Audit

Quarterly partner audits; require app attestation & breach-notification clauses.
Board KPIs: # high-priv apps, token age, export volumes, partner incidents, MTTR.
Red-team: simulate OAuth abuse & bulk export from a partner IP; fix gaps.

FAQ

Was Salesforce “hacked” directly?

Public reporting emphasizes customer-side compromises (connected apps, vendors, tokens), not a core-platform breach. That’s why this is a supply-chain crisis.

What specific data was exposed at Qantas?

Names, emails, phone numbers, dates of birth, frequent-flyer numbers and related service data; no credit cards or passports per Qantas statements.

How should integrated brands respond now?

Block default external exports, re-consent apps, rotate tokens, enforce partner IP/device controls, and implement the detections above—then run an extortion tabletop within 30 days.
