Claude sessions stolen, usage jumps 10 points

Anthropic says infostealer malware stole Claude login sessions; one subscriber’s usage climbed from 45% to 55% while no work ran on a $200-per-month plan, according to TechCrunch’s account. Anthropic invalidated sessions and refunded part of that account, but the episode leaves a builder-facing gap: shared agent spend needs session revocation and itemized usage, the same approval boundary highlighted by Claude’s checkout controls.
