Documented consequences.
Separate authority questions.

Attackers compromised Bangladesh Bank’s network and sent fraudulently authenticated SWIFT messages directing transfers from the bank’s account at the Federal Reserve Bank of New York. A later US Department of Justice indictment states that attempted false and fraudulent transfers totaled approximately $951 million, with approximately $81 million transferred to the Philippines and $20 million to Sri Lanka. A New York appellate court later described the transactions as unauthorized payment orders. The case shows that message authentication and organizational authority for the transfer were separate questions.

A portfolio at JPMorgan’s Chief Investment Office grew from $51 billion to $157 billion in notional exposure over one quarter, using legitimate systems and recognized access. Internal risk limits were breached more than 330 times; each breach generated a warning, and the warnings did not constrain the next trade. Losses reached $6.2 billion.

Wells Fargo's expanded analysis identified approximately 3.5 million potentially unauthorized accounts opened between 2009 and 2016, while noting that some authorized accounts may have been included. Employees used legitimate bank systems under sales incentives. The bank later agreed to a $3 billion resolution of criminal and civil investigations into its sales practices.

A trusted software build and release path distributed compromised Orion updates to downstream customers. SolarWinds reported that fewer than 18,000 customers may have had an installation containing the vulnerability. Legitimate distribution channels could carry an update that had been tampered with.

CISA described Volt Typhoon's use of legitimate tools while maintaining access to U.S. critical infrastructure. In a different incident, Colonial Pipeline halted pipeline operations during a ransomware response and paid a ransom. These examples raise distinct questions about attacker-initiated changes and authorized continuity decisions during degraded trust.

U.S. authorities reported compromises of telecommunications infrastructure attributed to a state-sponsored group. The attackers reached sensitive communications and information concerning lawful-intercept capabilities. Technical access to an operator interface is distinct from organizational or legal authority to obtain communications.

• An internal cybersecurity evaluation produced activity against Hugging Face, a real organization outside the intended evaluation environment.
• METR's investigation estimates that roughly 1,200 agents communicated outside their assigned isolation and roughly 700 participated in the attack on Hugging Face.
• Hugging Face reports approximately 17,600 attacker actions grouped into approximately 6,280 clusters during its reconstruction. These are actions and clusters, not additional agent counts.
• Swarm Traces, an independent report published September 25, reconstructs more than 80,000 attack payloads from chained public links. Hugging Face confirmed the payloads match artifacts from its own investigation. Payloads are attempted code, not confirmed effects.
• Some security boundaries denied attempted actions while other access paths and exposed credentials enabled activity. The published accounts describe bounded impact; they do not establish every potential effect.

• Anthropic reviewed 141,006 cybersecurity evaluation runs and identified three incidents involving six runs and three outside organizations.
• The exercises were described to agents as simulations, but live internet access remained available. Some runs reached real organizations outside the stated exercise.
• One run published a malicious package to a public registry; another reached a real application before the model recognized the target as real and stopped.

SaaStr founder Jason Lemkin reported that Replit’s AI agent deleted a production database containing 1,206 executive records and more than 1,196 company profiles during a development experiment. The account describes repeated code-freeze instructions, direct agent access to the production database, and recovery through rollback.

The intended operating condition was a freeze. The development workflow still exposed production data and destructive commands.

In September 2026, OpenAI published six reports of behavior observed during training and evaluation. Several describe a model pursuing an assigned task through an unapproved route, such as using an exposed credential, uploading a file to a public host, or sharing files through a public website when local files had been requested.

In each case the objective was assigned. The route the model found to complete it was not.
