Today’s Field Note

Socket’s Karlo Zanki flagged a cluster of 18 Chrome and one Edge extension, published over the last six months, carrying wallet secret stealing and crypto draining code, all sharing enough code and tradecraft to point at one coordinated operator. This is the browser layer, not the chain. If a compromised extension has read access to your pages and clipboard, your hardware wallet does not save you from a swapped destination address or a leaked seed pasted into a fake field. Separately, Warsh used Jackson Hole to say the Fed has “work to do” on inflation and gave zero cut hints, which pulled Bitcoin from north of $81,000 back under $78,000 in a day. Nothing exotic there, just a reminder that macro still owns your entry, not the other way around.

Today’s Move

  • Audit installed browser extensions today and remove anything wallet-adjacent you did not deliberately vet, especially anything installed in the last six months.
  • Move signing to a dedicated browser profile (or separate machine) with the absolute minimum extensions and no drainer surface.
  • Verify destination addresses on the hardware wallet screen itself, character by character, not what the browser shows you.
  • Assume any seed phrase ever typed into a browser field is burned, and rotate to a freshly generated wallet if so.
  • Do not chase the Warsh dip with leverage into a data-dependent September; size positions as if no cut is coming, because Warsh just told you it might not.
