The Breach Risk Index (BRI) is a proprietary 0–100 score rating how dangerous a breach is right now, based on how recently the data has been circulating on the dark web and how valuable it is to attackers.
Breach Summary
In September 2021, a publicly accessible PostgresSQL database belonging to the Playbook service was identified. Run by VC firm Plug and Play Ventures, the database had been exposed since October 2020 and contained more than 50 thousand unique email addresses along with names, phone numbers, job titles and passwords stored as PBKDF2 hashes. It took more than 2 weeks after being notified of the exposed data to properly secure it.

Breach Impact
The exposure of credentials alongside personal data heightened account-takeover and reuse risk for Playbook users and drew scrutiny of its data protection.
Exploitation & Downstream Threats
• Credential stuffing against reused passwords across other platforms | • SIM swap attacks where phone numbers are present | • Targeted phishing campaigns using exposed email addresses | • Employment-based social engineering using job and employer data | • Social media account targeting and impersonation
Principal Risk Advisory
What this means for a principal
A consumer-service breach: contact and account data supports phishing, account takeover and profile enrichment. For a high-profile principal the main risk is credible impersonation and enrichment of existing exposure.
What You Should Do
- Reset any reused passwords and enable MFA on email first, then financial accounts.
- Guard against SIM-swap and vishing: add a carrier port-out PIN and verify any 'support' calls independently.
- Do not use unofficial 'am I affected' lookups; several are themselves harvesting operations.
How ObscureIQ Can Help
- Corpus confirmation: determine whether and where the principal (plus household and staff) appear in this dataset and which specific fields are exposed for them.
- Exposure mapping and footprint neutralization: cross-reference against broker-available data and suppress still-removable elements, prioritizing address and phone, since this record re-seeds broker networks.
- ThreatWatch tuned to this incident's identifiers and misuse pattern (impersonation and targeting patterns, not generic credential monitoring).
