Solflare Crypto Wallet Vulnerability - "xpass exploit"

[cyclone]

@blandy Thanks! Hopefully Solflare users will transfer their crypto to a secure wallet before a threat actor exploits this in the wild.
@oe3p32wedw That is correct. The encryption function Solflare used is similar to Phantom, which is secretbox with pbkdf2-sha256 KDF. To clarify, the encryption function is secure, but the vulnerability is what Solflare did after the encryption function.

Cyclone, this very much annoys me. How could you do this? I found this vulnerability and I had ALREADY reported it.

I independently found the vulnerability while reverse engineering the encryption function, wrote the solflare_pwn toolkit, and reported the vulnerability on Feb 12 to Solflare with a followup email on Feb 15. All of this with timestamps is disclosed on my post above.

This is the 2nd time rickyc2024 has publicly taken credit for my solflare_pwn toolkit and my work on this project. To once again clarify, he has nothing to do with solflare_pwn or me discovering the vulnerability.

I can confirm I've worked with @cyclone and also have a working C# copy of the decrypter and also the vulnerability.

Nice work @cyclone

@cyclone will you create versions of these for firefox aswell?

@dawp9duhn9gom
I can port the toolkit to Firefox if there is enough interest. However, I generally do not write tooling for Firefox due to the very low global usage only being approx 2%, while Chrome based browsers dominate the global usage at over 70%.
