The most common AI use was preparation, with 67.3% of accounts using AI for tasks like malware creation. But the study found a clear shift: AI-assisted phishing dropped 8.6% while AI use for identifying valid accounts inside compromised networks rose 8.9%. Attackers classified as medium risk or higher jumped from 33% in the first six months to 56% in the second six months.\u003c/p\u003e\u003cp\u003eAnthropic also reported that traditional risk indicators no longer work. The least skilled attackers used an average of 16 techniques, while the most skilled used about 20, and the platform used showed no correlation with risk level.
