Skiff: Various Privacy Failures
Disagree, their reputation is tied to their audit quality.
But I'm pretty sure in this case the scope was bad. Like they coukd have had audits on "Do I use OpenSSL well?" and then misrepresent that all their privacy claims were audited.
Now it seems like Skiff conveniently didn't allow Trail of Bits to publish their reports, they are usually here: https://github.com/trailofbits/publications/tree/master/revi...
Disclaimer, I have used Trail of Bits service in the past (and 2 other auditors for an security campaign on a blockchain, cryptography + networking product).

PyPI has completed its first security audit

They seem to not have analysed client-side of PIP itself, but I suppose there isn't anything you could say that isn't already obvious to everyone.

Thoughts on Skiff? What do you like? What would you want to see improve?
Audits are mentioned on the Trail of Bits website https://github.com/trailofbits/publications and the Skiff one https://skiff.com/transparency. Skiff has been externally audited 4 times.

Transparency at Skiff
Hi! I'm Skiff's CEO. We've had 3 security audits, including 2 from Trail of Bits - one of the best security auditing firms in the world https://github.com/trailofbits/publications. Skiff Mail is also open-source: https://github.com/skiff-org/skiff-mail as is our whitepaper https://skiff.com/whitepaper We've also been in the news quite a bit: https://www.theverge.com/2022/5/17/23075804/skiff-mail-email-privacy, https://www.wsj.com/articles/encryption-bans-what-is-this-russia-hacking-online-privacy-security-data-signal-whatsapp-emails-protection-11675436242 (I wrote this with our team!), https://techcrunch.com/2023/01/30/russia-skiff-block/, and more, even though we're only a year old. We collect no personally identifying information - not even IP addresses used - no backup emails, phones, etc. - no advertising, and we end-to-end encrypt BOTH email subject + body and don't have any metadata (time sent/received an exception). What can we do to share more of this with more people? We're a younger company but it's so important this is made public.

Fuzzing Around: Better Smart Contract Testing through the Power of Random Inputs
Fuzzing has been around for a while in traditional full-stack development, but a new class of tools is here that can apply fuzzing to smart contract testing in web3. Some of the fuzzing tools include the open source Echidna and MythX.

Smart Contract Audits with ConsenSys Diligence Fuzzing - Fuzzing as a Service
Fuzzing has been around for a while. Defensics and Burp Suite are some examples in the traditional development world. There are also several web3/blockchain fuzzing tools available, such as Echidna and Foundry. However, Diligence Fuzzing is fuzzing as a service and makes everything a little simpler to implement. Which in the end means better audits and more secure contracts. So let’s look into it in more detail.
- Echidna 2.1.1 released with fixes and reduced memory footprint!
