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 late 2025 and early 2026, the cyber-extortion group ShinyHunters (often operating under the moniker "Scattered Lapsus$ Hunters") targeted Harvard University, specifically compromising the Alumni Affairs and Development (AAD) department. The breach, which was initially disclosed by the university in November 2025 following a sophisticated "vishing" (voice phishing) attack, resulted in the exfiltration of a massive dataset.

Breach Impact

Exploitation & Downstream Threats
• Identity verification bypass using name + date of birth combination | • SIM swap attacks where phone numbers are present | • Targeted phishing campaigns using exposed email addresses
Principal Risk Advisory
What this means for a principal
An education-sector breach: student, staff and identity records support identity theft and targeted phishing. For a high-profile principal the main risk is credible impersonation and enrichment of existing exposure.
What You Should Do
- 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).
