WASABI WALLET

DESCRIPTION OF EVENTS

"WASABI WALLET The leading Bitcoin wallet for desktop featuring coinjoin. It's free, open-source, and non-custodial. Reclaim your privacy today."

 

"Wasabi is a non-custodial hot wallet that requires a connection to the internet and cryptocurrency network to work. As a wallet, Wasabi values user privacy and anonymity. This is evident in its built-in CoinJoin, coin control, and Tor integration features that help to keep users and their IP addresses anonymous. This further prevents security breaches and data leaks."

 

"Wasabi Wallet is an open-source, non-custodial, privacy-focused Bitcoin wallet with built-in coinjoins. It is a piece of software that runs on your computer and helps you to manage your bitcoins. Although Wasabi has some very advanced magic under the hood, it is rather easy to use. You can generate a new set of seed words, or import already existing ones. With Wasabi you can receive bitcoins into your full control, and you can send them to someone else without needing permission from any other person or entity. There is also a powerful auto-coinjoin feature to help obfuscate your transaction history. You can use Wasabi to manage your hardware wallet, and it even connects to your own full node. Of course, Wasabi is libre and open-source, which means you have full control over the software you manage your money with"

 

"Unfortunately, GitHub doesn't offer granular permissions to restrict who can modify binaries - all contributors with Write access have this capability."

 

"[The Wasabi Wallet team] were alerted by the @BinaryWatch.org bot about a hash discrepancy in the Wasabi-2.0.8.1.msi release, specifically on the Windows installer."

 

"It was discovered that the Windows installer had been replaced with a different file. Despite [the team's] recent efforts to reduce this attack surface by revoking access rights for zkSNACKs contributors, an account with Write access was compromised."

 

"The fraudulent Wasabi-2.0.8.1.msi file was promptly removed, and we are closely monitoring the releases."

 

"We extend our gratitude to @BinaryWatch.org for their service, as their prompt report significantly minimized the impact of this incident."

 

The team has "since revoked additional access rights."

 

"We were aware of the vulnerability and this specific scenario, but our current release procedure is too cumbersome for our small team, resulting in a delay in patching this exploit. We had already been planning to streamline our release process to enable more frequent updates."

Wasabi Wallet is a bitcoin wallet which supports the privacy maximizing CoinJoin protocol, which helps make it much more challenging to track the origin and destination of bitcoin which go through the wallet. While the wallet is open-source and distributed through Github, many users will simply install a pre-compiled binary, particularly for Windows users. The binary for Wasabi Wallet version 2.0.8.1 on Windows (Wasabi-2.0.8.1.msi) was replaced with a suspected malicous version, which remained online for a brief period. The suspected malicious version was removed quickly, and there is uncertainty as to whether a copy even exists anywhere to be analyzed and understand the intent of the uploader.
