Brinztech Alert: “InWebsiteBuilder” (Insurance B2B) Breached; 18k Agent PII, Profile Pics, & OAuth “Digital Fingerprints” Leaked

Dark Web News Analysis

The dark web news reports a highly targeted data breach against “InWebsiteBuilder,” a B2B SaaS platform for the insurance industry. The database, containing 18,047 records, is leaked on a hacker forum.

The victims are not end-users; they are the 18,047 insurance agents/agencies who use the platform.

Key details of the (CRITICAL) leaked data:

• Full PII: First Name, Last Name, Email, Username, Gender, Locale.
• “Digital Fingerprint” Data:
  • OAuth UIDs (e.g., the permanent Google/Facebook account ID).
  • OAuth providers (tells the attacker which service to target).
  • profile pictures (allows for perfect visual impersonation).
  • links (likely to the agent’s social media profile).

Key Cybersecurity Insights

This is a critical-severity supply-chain incident. The primary threat is not to the agents themselves, but to the thousands of clients/customers they service.

1. CRITICAL: The “OAuth Digital Fingerprint” Leak: This is the most severe threat. A password can be changed; an OAuth UID is permanent. An attacker now has the unchangeable unique identifier for an agent’s personal Google or Facebook account, plus their real name, email, and photo. This enables:
   • Perfect Impersonation: The attacker can create a new, fake email or social media profile that looks identical to the real agent (using their name and real photo) and is impossible to distinguish at a glance.
   • Targeted Social Engineering: The attacker knows exactly which platform to target (e.g., “I see you log in with Google…”).
2. IMMEDIATE Risk of Supply-Chain Insurance Fraud: This is the #1 goal of the attack. The attacker now has a verified list of 18,000+ active insurance agents.
   • Attack Scenario: The attacker (impersonating the agent with their real name/photo) emails the agent’s client list (found on the agent’s public site).
   • The Script (Spear-Phishing): “Hello [Client Name], this is [Agent Name] (see my photo!). We are updating our payment system for your policy. Please remit your next premium to this new account…” or “Please log in to our new client portal [phishing link] to review your policy documents.”
   • This will be used for mass insurance fraud, client poaching, and stealing the PII of the end-customers.
3. Implied Credential Stuffing Risk: The mitigation mentions “password reset.” This implies password hashes were also leaked. This is a standard, immediate threat. Attackers will “stuff” the (email + cracked password) combos into other sites.
4. Severe Regulatory Failure (USA): As a B2B service for the US insurance industry (a highly regulated financial sector), this is a severe data breach under state-level laws (e.g., NY SHIELD Act, CCPA).
   • The company is legally required to notify its 18k B2B clients (the agents) “without unreasonable delay.”
   • It must also report this breach to all relevant State Attorneys General.

Mitigation Strategies

This is a B2B counter-impersonation crisis.

1. For InWebsiteBuilder (The Company):
   • IMMEDIATE Investigation & Containment: Activate IR, find the vector (likely SQLi or exposed database) NOW.
   • MANDATORY: Notify B2B Clients (The Agents): Immediately notify all 18,047 agents. The warning must be transparent about the OAuth and profile picture leak and the specific, high risk of being impersonated by attackers to defraud their clients.
   • MANDATORY: Regulatory Reporting: Report to all relevant State Attorneys General and insurance regulators.
   • Force Password Reset & MFA: (As suggested) Force a password reset and immediately implement MFA for all agent accounts.
2. For Affected Insurance Agents (The Victims):
   • CRITICAL: Proactively Warn Your Own Clients. You must send an email to your entire client book now. Warn them that an attacker may try to impersonate you (using your real name and photo). State that you will never ask for credentials or payment changes over a new, unfamiliar email.
   • CRITCAL: Change Reused Passwords NOW. If you reused your InWebsiteBuilder password on any other site (email, bank, etc.), change that password immediately.
   • Lock Down Social Media: Set your Facebook/Google (or other leaked OAuth provider) profile to “private.” Be on HIGH ALERT for spear-phishing attempts on those platforms.
