Anthropic confirmed infostealer malware hijacking Claude login sessions to drain usage. The company forcibly logged out affected users, removed their payment methods, and refunded unauthorized charges. The malware copies browser cookies and credentials, so two-factor authentication does not stop it. One Reddit user reported infection from pirated games.
Anthropic's annualized revenue has surpassed $65 billion, about seven times the figure at the end of 2025. Preliminary second-quarter sales exceeded $11.5 billion, more than 14 times the year-ago period. Growth is driven by the coding agent Claude Code and enterprise adoption through major clouds. The company is expanding computing infrastructure to meet demand.
Anthropic released results from an unreleased research version of Claude attempting the Riemann hypothesis. Claude failed to prove the conjecture itself but derived a new lower bound: at least two thirds of the zeta function's nontrivial zeros lie on the critical line, with an optimized figure around 67.25 percent. The previous bound stood at roughly 41.7 percent. The human operator mainly encouraged Claude with phrases like "keep going" and "believe in yourself".
Anthropic has created a new technology called J-Lens that allows observation of the internal processes of large language models. Applied to Claude Opus 4.6, J-Lens reveals a 'J-space' where upcoming output words emerge. When the model decides to fabricate information, the words 'panic' and 'fake' repeatedly appear in this space.
