MetaMask Security Monthly: September 2022

This month, a little news from the Lab and some scams to be aware of…

Security Laboratory

​Manchester Mark 1 Computer, 1948.

Endo

Big news in Endo is the latest attempt to refactor SES shim’s evaluator into a multilayered scope stack, also referred to as “quadruple backflip”. While it’s still in review, it’s looking good for inclusion in the next release. It addresses an issue of leaking the scope proxy and separates different concerns in global scope handling. There’s also a benefit to LavaMoat — it’s going to be able to use the unaltered SES shim when “quadruple backflip’ lands.

LavaMoat

  • Documentation refresh shipped
  • New ways to use lavamoat-node: a convenience helper for running commands from node_modules/.bin and a programmatic usage API.
