Please follow Unstoppable Wallet and thank them for being reproducible via their Twitter!
The following Analysis is not a full code review! We plan to make code reviews available in the future but even then it will never be a stamp of approval but rather a list of incidents and questionable coding practice. Nasa sends probes to space that crash due to software bugs despite a huge budget and stringent scrutiny.
Do your own research!
Try out searching for "lost bitcoins", "stole my money" or "scammers" together with the wallet's name, even if you think the wallet is generally trustworthy. For all the bigger wallets you will find accusations. Make sure you understand why they were made and if you are comfortable with the provider's reaction.
The Analysis ¶
Here we test if the latest version can be reproduced, following the known procedure expressed in our test script:
===== Begin Results ===== appId: io.horizontalsystems.bankwallet signer: c1899493e440489178b8748851b72cbed50c282aaa8c03ae236a4652f8c4f27b apkVersionName: 0.23.0 apkVersionCode: 54 verdict: reproducible appHash: 48c001371aefcf74a39202965b84b5cccdeea6897d03eece3989ac4017d46d95 commit: fe15c675ff8076eb6216e8653358f0bc8501a316 Diff: Only in /tmp/fromPlay_io.horizontalsystems.bankwallet_54/META-INF: MANIFEST.MF Only in /tmp/fromPlay_io.horizontalsystems.bankwallet_54/META-INF: RELEASEK.RSA Only in /tmp/fromPlay_io.horizontalsystems.bankwallet_54/META-INF: RELEASEK.SF Revision, tag (and its signature): ===== End Results =====
which is what we want to see to give this wallet the verdict: reproducible
Thank you to Horizontal Systems for repeat donations
The binary provided was reproducible from the code provided.
As part of our Methodology, we ask:Does the binary we built differ from what we downloaded? If not, we tag it Reproducible
If we can reproduce the binary we downloaded from the public source code, with all bytes accounted for, we call the product reproducible. This does not mean we audited the code but it’s the precondition to make sure the public code has relevance for the provided binary.
If the provider puts your funds at risk on purpose or by accident, security researchers can see this if they care to look. It also means that inside the company, engineers can verify that the release manager is releasing the product based on code known to all engineers on the team. A scammer would have to work under the potential eyes of security researchers. He would have to take more effort in hiding any exploit.
“Reproducible” does not mean “verified”. There is good reason to believe that security researchers as of today would not detect very blatant backdoors in the public source code before it gets exploited, much less if the attacker takes moderate efforts to hide it. This is especially true for less popular projects.
