As a result of a Chromium vulnerability affecting all launched variations of the Mist Browser Beta v0.9.3 and under, we’re issuing this alert warning customers to not browse untrusted web sites with Mist Browser Beta presently. Customers of “Ethereum Pockets” desktop app will not be affected.
Affected configurations: Mist Browser Beta v0.9.3 and under
Chance: Medium
Severity: Excessive
Malicious web sites can doubtlessly steal your personal keys.
As Ethereum Pockets desktop app doesn’t qualify as a browser — it accesses solely the native Pockets Dapp — it isn’t topic to the identical class of points current in Mist. For now, it is strongly recommended to make use of Ethereum Wallet to handle funds and work together with good contracts as a substitute.
Mist Browser’s imaginative and prescient is to be an entire user-facing bridge to the ethereum blockchain and set of applied sciences that compose the Web3. The browser paves a big path for the subsequent Net our ecosystem is proudly constructing.
Safety-wise, making a browser (an app that masses untrusted code) that handles personal keys is a difficult job. Over the course of the final 12 months, now we have had Cure53 conduct an intensive safety audit of Mist, and vastly improved the safety of each the Mist browser and the underlying platform, Electron. We have promptly mounted discovered safety points.
However that’s not sufficient. Safety within the browser area is a unending battle. The Mist browser relies on Electron, which relies on Chromium. Every new Chromium launch fixes quite a few safety points.
The layer between Mist and Chromium, Electron, is a undertaking led by GitHub that goals to ease the creation of cross-platform purposes utilizing JavaScript. Lately, Electron hasn’t saved updated with Chromium, resulting in an growing potential assault floor as time passes.
A core downside with the present structure is that any 0-day Chromium vulnerability is a number of patch-steps away from Mist: first Chromium must be patched, then Electron must replace the Chromium model, and at last, Mist must replace to the brand new Electron model.
We’re analyzing how we might cope with Electron’s not-so-frequent launch schedule, to scale back the hole between Chromium variations we use. From preliminary research, Brave’s Muon (an Electron fork) follows Chromium updates carefully and is one potential possibility. The Courageous browser, which additionally comprises a cryptocurrency pockets integration, has the same threat-model and calls for for safety as Mist.
An vital reminder: Mist remains to be beta software program, and you need to deal with it as such. The Mist Browser beta is supplied on an “as is” and “as out there” foundation and there aren’t any warranties of any variety, expressed or implied, together with, however not restricted to, warranties of merchantability or health of function.
Fast safety guidelines:

- Again up your personal keys — Cloud companies will not be the most suitable choice to retailer it.
- Don’t go to untrusted web sites with Mist.
- Don’t use Mist on untrusted networks.
- Hold your day-to-day browser up to date.
- Hold monitor of your Working System and anti-virus updates.
- Learn to confirm file checksums (link).
Lastly, we wish to thank the safety researchers that labored exhausting on reproducing and making invaluable submissions by means of the Ethereum Bounty program.
