Bank of America hires 1,000 contractors to fix AI-exposed software flaws
Bank of America has become the first major bank to publicly quantify the cost of defending against AI-driven cyber threats, specifically those exposed by Anthropic's 'Mythos' AI model. The bank is hiring 1,000 contractors to support 3,000 internal staff in patching vulnerabilities, contributing to third-quarter costs of 'a couple hundred million plus', blended with anti-money laundering fixes. CEO Brian Moynihan's figures highlight the dual-edged nature of AI: while defense costs are high, the bank's 130 internal AI projects are projected to generate $700 million in savings by 2027. This development underscores a growing disparity, as most banks cannot fund such a large-scale response, making vendor contract terms critical. The article also covers OpenAI UK's 2025 accounts, revealing the high cost of frontier AI talent, and Citibank's decision to block AI agents, following JPMorgan's lead, to protect customer accounts.
This news is important because it reveals the real-world financial and operational impact of advanced AI models like Mythos on large enterprises, highlighting the cost of defending against AI-enabled vulnerabilities.

Banks Alarmed by Anthropic's Mythos AI Model
European banks and financial regulators are reviewing risks after Anthropic unveiled its new AI model, Mythos, which reportedly can identify cybersecurity vulnerabilities in code and systems. Deutsche Bank CEO Christian Sewing said banks are in close contact with European supervisors and monitoring the issue within risk management processes. Anthropic has limited access to Mythos to a select group of (primarily US) companies and authorities under a project called "Glasswing." German and European agencies — including the BSI, BaFin and ECB supervisors — are assessing potential impacts, and US officials convened urgent talks with major US bank CEOs to discuss mitigation measures. Industry groups expect rapid software updates and coordinated responses if vulnerabilities are discovered.
Anthropic Unveils Ten AI Agents for Finance
Anthropic CEO Dario Amodei warned on May 5, 2026 that the company’s Mythos model has uncovered tens of thousands of software vulnerabilities, creating a limited six- to 12-month window to patch issues before comparable AI capability spreads. Speaking at an Anthropic financial‑services event where he shared the stage with JPMorgan Chase CEO Jamie Dimon, Amodei said most discovered vulnerabilities remain unpatched and that restricted access to Mythos is necessary to limit misuse. At the same event Anthropic unveiled a suite of 10 AI agents for banking and back‑office work, announced a unified Microsoft Office integration, and said its model Claude Opus 4.7 leads benchmarks for financial analysis. Amodei urged automotive-style safety guardrails and framed the moment as a danger that, if managed correctly, could yield long‑term benefits.
OpenAI Partners with Customers Bank to Automate Finance
Customers Bank has signed a multiyear partnership with OpenAI to embed OpenAI engineers at the regional lender and co-develop AI tools to automate lending, client onboarding and back-office workflows. CEO Sam Sidhu disclosed that his prepared earnings-call remarks were delivered by an "AI clone," and said the bank aims to improve its efficiency ratio from about 49% to the low 40s and lift returns starting in 2027. Customers Bank expects to deploy AI agents across lending, deposits and payments within six to 12 months, potentially cutting commercial loan timelines from 30–45 days to about seven days and reducing complex account openings to under 20 minutes. OpenAI CRO Denise Dresser said the company is proud to support the bank's move toward a more intelligent operating model.
