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 November 2024, the threat actor Nam3L3ss published employee-directory data on BreachForums drawn from the 2023 MOVEit Transfer (Cl0p) mass-exfiltration, including roughly 288,297 rows attributed to Bank of America dating to May 2023. Exposed fields are employee-oriented: full names, job titles, internal cost-center codes and names, phone numbers and business email addresses. This is a repost of MOVEit-era corporate directory data, distinct from the separate Infosys McCamish third-party breach that exposed about 57,000 BofA customers' identity and financial data.

About Bank of America
Bank of America is one of the largest US banks and a globally systemically important financial institution, headquartered in Charlotte, North Carolina. It provides consumer and commercial banking, wealth management (Merrill) and investment-banking services to individuals, businesses and institutions worldwide.
Why They Hold Your Data
This record concerns Bank of America employee-directory data rather than customer financial records: names, job titles, internal cost-center codes and names, phone numbers and business email addresses of the type held in corporate HR/directory systems, exposed through a third-party file-transfer compromise.
Recent Developments
In November 2024 the actor Nam3L3ss posted employee-directory datasets on BreachForums, including about 288,000 Bank of America rows, sourced from the 2023 MOVEit (Cl0p) mass-exfiltration and dating to May 2023. This is separate from the Infosys McCamish incident that exposed roughly 57,000 BofA customers' data.

Breach Impact
Because the data is corporate directory information rather than customer identity or financial data, the primary harm is to employees and the bank's internal attack surface: detailed org hierarchies and contacts enable highly targeted social engineering against a major bank. Its re-release in 2024 extends the useful life of the 2023 MOVEit exfiltration.
Exploitation & Downstream Threats
• SIM swap attacks where phone numbers are present | • Targeted phishing campaigns using exposed email addresses
Principal Risk Advisory
What this means for a principal
A financial-institution breach: account, wealth or payment data supports direct fraud and highly credible financial-impersonation scams. 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).
N
Threat Actor: Nam3L3ssConfidence: Medium-High
Motivation: Financial, reputation
A forum actor tied to the release of datasets believed to originate from the MOVEit campaign, including employee data from large organizations. Public reporting frames Nam3L3ss as a post-compromise leaker or distributor rather than necessarily the original intruder.
