Strengthening our defenses against distillation attacks
Illicit distillation allows model developers to copy frontier AI capabilities without creating proportionally robust safeguards. Here, we describe how we’ve reduced the rate of distillation by more than 90%.
2026 Usage Policy update
We’re publishing a new version of our Usage Policy. In this post, we summarize the changes we’ve made.
Detecting and countering misuse of AI: September 2026
Over the past eight months, our Threat Intelligence team identified and disrupted operations in which threat actors tried to use Claude for malicious activity. In this report, we share case studies from those operations and describe how malicious use of Claude has evolved since our previous threat reports in 2025.
What we learned mapping a year’s worth of AI-enabled cyber threats
As AI changes how cyberattacks happen, how well do the security community's frameworks hold up? A new report maps attacks onto MITRE ATT&CK.
Mapping AI-enabled cyber threats: Insights from the LLM ATT&CK Navigator
We’ve spent the past year investigating how threat actors are weaponizing AI to conduct cyber operations. Today, we’re sharing a new analysis that maps these real-world attacks onto the MITRE ATT&CK framework.
An update on our election safeguards
We explain what we’re doing to ensure Claude plays a positive role in the US midterms and other major elections around the world this year.
Reverse engineering Claude's CVE-2026-2796 exploit
This post dives deep into how Claude wrote an exploit for one of the vulnerabilities it found in Firefox.
Detecting and preventing distillation attacks
We have identified industrial-scale campaigns by three AI laboratories—DeepSeek, Moonshot, and MiniMax—to illicitly extract Claude’s capabilities to improve their own models.
Disrupting the first reported AI-orchestrated cyber espionage campaign
In September 2025, we detected and disrupted a highly sophisticated cyber espionage campaign. We’re sharing this case publicly to help others strengthen their own defenses.
Building AI for cyber defenders
We invested in improving Claude's ability to help defenders detect, analyze, and remediate vulnerabilities in code and deployed systems. This work allowed Claude Sonnet 4.5 to match or eclipse Opus 4.1 in discovering code vulnerabilities and other cyber skills. Adopting and experimenting with AI will be key for defeners to keep pace.
Detecting and countering misuse of AI: August 2025
We’ve developed safeguards to prevent the misuse of our models, but malicious actors are actively attempting to find ways around them. Today, we’re releasing a report that details how.
Building safeguards for Claude
How Anthropic's Safeguards team protects users, from policy and pre-deployment evaluations to real-time classifiers.
Detecting and countering malicious uses of Claude: March 2025
This report outlines several case studies on how actors have misused our models, as well as the steps we have taken to detect and counter such misuse.
