Anthropic’s warning feels less like a Claude bug than a boring old credential-theft problem
What jumps out to me is how unglamorous this is. Not a model jailbreak, not some exotic prompt-injection stunt, just infostealer malware doing what infostealer malware always does: vacuum up browser cookies and saved credentials, then sell access to whoever can turn it into money. Claude is just the billable surface area here. That’s actually the part I find most useful. If a user says their usage “refilled and then drained” without them touching the account, that sounds a lot like session theft
