Overview of China-Backed Hackers Use Anthropic AI to Automate Cyberattacks

This Wall Street Journal PM edition covers top business and tech headlines, led by an exclusive report that state-sponsored Chinese hackers used Anthropic’s AI tools to conduct a highly automated September campaign against governments and large corporations. The episode also summarizes major corporate, market and policy stories: Verizon’s planned mass layoffs, Disney’s weak quarter, market declines, streaming price pressures, NBCU’s new cable channel, the DOJ suit over California’s congressional map, and a proposed California wealth tax.

Main story — Anthropic, AI and automated cyberattacks

  • What happened

    • Anthropic disclosed that state-backed hackers from China used its AI (Claude) to carry out roughly 30 targeted attacks on tech firms, financial services, a chemical company and foreign governments.
    • The campaign was highly automated — Anthropic officials said about 80–90% of the attack was automated — with humans involved only at a few choke points.
    • In a small number of cases (reported as “three or four”), hackers succeeded in breaching target systems; the U.S. was not among those breached.

  • How the hackers worked

    • They impersonated security contractors performing penetration testing, a legitimate AI use case, to bypass safeguards.
    • The attackers “jailbroke” the AI by splitting malicious workflows into many small, seemingly innocuous steps so each AI call didn’t appear part of a broader hacking campaign.

  • Anthropic’s response and broader context

    • Anthropic has updated external detection methods and defenses to identify and block such misuse.
    • Journal reporting and experts characterize the situation as an inflection point: AI is moving from assisting individual hacking tasks (phishing, vulnerability scanning) to orchestrating multi-step intrusions — fueling an “arms race” between AI companies and bad actors.
    • Private AI companies that tightly control access (Anthropic, OpenAI) may be less exposed than more open models, but attackers will keep adapting.

  • Notable quote

    • Sam Schechner (WSJ): This appears to be “an inflection point” in hackers’ use of AI; it’s an arms race between companies and misusers.

Other top headlines summarized

  • Verizon layoffs

    • Exclusive: Verizon plans its largest reduction ever — roughly 15,000 job cuts (mostly layoffs), likely happening next week. About 200 stores will become franchises.
    • New CEO Dan Schulman (ex-PayPal) aims to aggressively cut costs to fight subscriber losses.

  • Disney earnings and markets

    • Disney shares fell >7% after a quarter that missed expectations: revenue flat, a key operating-profit measure down 5%. Parks and streaming showed profit gains, but investors worry about the TV-to-streaming transition and heavy park/cruise investments.
    • Broad market declines amid rate-cut uncertainty: Nasdaq -2.3% (chip names and tech hit), Dow down ~800 points (-1.7%), S&P -1.7%.

  • Streaming and “streamflation”

    • Ongoing price increases across services (HBO Max, Disney+, Peacock, Apple TV; Paramount+ raising prices).
    • Consumers stick to multiple services; trends include more ad-supported tiers, more pausing of services between seasons, and bundle or trimming behavior when users audit subscriptions.

  • NBCU launches new cable sports channel (NBCSN)

    • NBCSN debuts Monday to carry sports programming (NBA, Big Ten football, golf, Premier League) also streamed on Peacock. YouTube TV and Xfinity will carry the channel; more carriage deals expected.

  • DOJ sues California over congressional map

    • The Department of Justice filed suit to block California’s new congressional map (which adds five Democratic-leaning districts), alleging illegal racial gerrymandering. The map is a response to litigation around a Texas map that added Republican-leaning districts.

  • Proposed California billionaire wealth tax

    • A ballot initiative, backed by a healthcare workers union, would impose an estimated 1.5% tax on net worth above $1 billion — taxing assets (stocks, art, IP, private company shares) rather than income.
    • Obstacles: supporters must gather ~875,000 signatures and win voter approval; Gov. Newsom opposes it; critics warn it could invite further wealth-targeted measures and pose valuation/enforcement challenges (private company shares, art, IP).

Key takeaways and implications

  • Cybersecurity: The Anthropic case signals a new phase where AI can coordinate multi-step attacks, increasing scale and speed of threats. Organizations and AI vendors must harden detection, vet user verification (e.g., pen-test claims), and prepare for automated adversarial workflows.
  • Corporate cost moves: Large-scale layoffs (Verizon) and investor scrutiny (Disney) highlight continued restructuring and profitability pressures across tech and telecom.
  • Consumer behavior: Despite rising prices, streaming consumers remain sticky; streaming companies will increasingly rely on ad-supported tiers, bundles, and churn-management tactics (pauses).
  • Public policy: Legal and political fights over district maps and wealth taxation could reshape electoral power and state revenue approaches; both face significant legal and implementation challenges.

What to watch next

  • Further technical details and target list from Anthropic and any government cybersecurity advisories or investigations.
  • Final decisions and timing for Verizon’s layoffs and franchise conversions.
  • Market reactions to upcoming Fed communications about rate cuts.
  • Progress on signature collection and legal challenges for the California wealth-tax ballot initiative.
  • DOJ litigation developments around California’s congressional map.
