This shows one pathway by which LLMs could reduce barriers to entry for complex cyber attacks while also automating current cyber defensive workflows. Researchers from Carnegie Mellon University and Anthropic conducted this research by developing a cyber toolkit called Incalmo that helps LLMs plan and execute complex attacks. [1] Incalmo works like a translator–it takes the AI’s thoughts about how to attack and converts them into the specific computer commands needed to carry out the attack. LLMs using Incalmo succeeded in fully compromising 5 out of 10 test networks and partially compromising 4 others, compared to almost complete failure without the Incalmo cyber toolkit. Success entailed orchestrating a complex sequence of steps, including gaining initial network access, lateral movement..."},"evidence_pages":[],"related_signals":[{"id":"9caf7d39-0d96-42d0-8b59-e72f7e502ec4","url":"https://onlylabs.fyi/signals/9caf7d39-0d96-42d0-8b59-e72f7e502ec4","source_url":"https://www.anthropic.com/research/economic-index-june-2026-report","title":"Economic Index June 2026 Report","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-06-26T23:50:17+00:00","first_seen_at":"2026-06-26T16:00:32.297045+00:00","date_source":"sitemap.lastmod"},{"id":"6c78c028-3ab4-4b33-86f7-d86c8ba9e3ba","url":"https://onlylabs.fyi/signals/6c78c028-3ab4-4b33-86f7-d86c8ba9e3ba","source_url":"https://www.anthropic.com/research/agents-in-biology","title":"Agents In Biology","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-06-08T00:00:00.000Z","first_seen_at":"2026-06-09T02:17:26.339488+00:00","date_source":"page.visible_date"},{"id":"e4fbfcdd-15b4-41b9-b011-fd83e7068ae9","url":"https://onlylabs.fyi/signals/e4fbfcdd-15b4-41b9-b011-fd83e7068ae9","source_url":"https://www.anthropic.com/research/making-claude-a-chemist","title":"Making Claude A Chemist","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-06-05T00:00:00.000Z","first_seen_at":"2026-06-09T02:17:26.339488+00:00","date_source":"page.visible_date"},{"id":"b8472bfd-c32b-4d72-ae98-d8a4f1a1278f","url":"https://onlylabs.fyi/signals/b8472bfd-c32b-4d72-ae98-d8a4f1a1278f","source_url":"https://www.anthropic.com/research/exploit","title":"Exploit","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-03-06T00:00:00.000Z","first_seen_at":"2026-06-17T20:00:31.646229+00:00","date_source":"page.visible_date"},{"id":"5f0f346c-0718-4d81-a174-d18cae51efa3","url":"https://onlylabs.fyi/signals/5f0f346c-0718-4d81-a174-d18cae51efa3","source_url":"https://www.anthropic.com/research/critical-infrastructure-defense","title":"Critical Infrastructure Defense","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2026-01-08T00:00:00.000Z","first_seen_at":"2026-06-17T20:00:31.646229+00:00","date_source":"page.visible_date"},{"id":"b8ad5d26-1905-4d23-a2e0-c2c477cbb462","url":"https://onlylabs.fyi/signals/b8ad5d26-1905-4d23-a2e0-c2c477cbb462","source_url":"https://www.anthropic.com/news/core-views-on-ai-safety","title":"Core Views On Ai Safety","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"anthropic","name":"Anthropic","category":"frontier-lab"},"occurred_at":"2023-03-08T00:00:00.000Z","first_seen_at":"2026-06-09T02:17:26.339488+00:00","date_source":"page.visible_date"}]}
