- Credential and session theft — Phishing, stuffing, and OAuth token abuse recur across tech platforms.
- Cloud misconfiguration — S3 buckets, misconfigured APIs, and file shares expose data without a traditional "hack."
- Extortion without precise counts — Ransomware and leak-site actors often publish before victims confirm scope.
- Supply-chain spillover — npm, SDK, and CRM tenant breaches affect IBM customers even when corporate HQ databases stay intact.
