Ask HN: What are the common ways in which security fails in agile development?

This all stinks of Lazarus:

https://en.wikipedia.org/wiki/Lazarus_Group

I've done incident responses for this exact type of attack multiple times. They've gotten much better organized lately and will often contact developers directly (over LinkedIn or WhatsApp) to run this type of attack. (Although, usually pretending to run a test for a job interview -- which is maybe why the author was confused about the code)

I think this was posted because the of the recent Npm malware fiasco. The malware monkey-patched native JS functions to replace strings that matched crypto addresses in certain the fetch, and XMLHttpRequest functions:

Considering there's no way to check whether a function is monkey-patched, this just tells me the JavaScript ecosystem was not designed with malicious actors in mind

I wonder if this was cyber sabotage....

Obviously just speculation but considering the escalating tensions between Russia, the EU and the US, I wouldn't be surprised if it were

I work in the security industry and use WIZ and while I do despise all of the buzzword acronyms this industry has come up with, CSPMs have been one of the few tools that have actually made my life significantly easier. Due to the nature of the industry I work in, there is a lot of regulation that we need to comply with, and CSPMs (and wiz in particular) gives us both observability and alerting for all of our resources in our cloud environments, including the configuration of the cloud environments themselves. I don't know how they managed to get a $32B offer so soon after coming out of stealth, but considering the amount of problems it solves for me and my team, I can see why they're doing well financially. We're definitely happy with the pain point the product fixes.

I can now say "I know for a fact we have x number of AWS/GCP/Azure accounts that are either not using our IdP or 2A, here's a list" without having to script across multiple cloud APIs

Similarly, I can say "here's a list of people that accessed x resource in the last y days". It really makes my life easier when I want to access metrics about my company's cloud environments

I'm not too familiar with the situation in Portland, but I have heard that programs which decriminalize drugs and provide care centers are not effective without existing social nets such as solid unemployment programmes and public health programmes that treated addicts can use to get themselves out of the socio-economic hole they got themselves into

Maybe the US is lacking in those programmes and is why the drug legalization programme is not effective in Portland?

I think your accidentally misinterpreting the law

As explaine by the article, counterfeiting involves pretending to be a product it's not. For example, if you sell your hypothetical channel bags as genuine channel bags instead of as generic, no-brand bags, then that would be counterfeiting because you're pretending they're something that it's not. Using genuine apple parts in third-party screens is more comparable to putting channel bag straps (which, yes, have the channel logo on them) into fake bags and selling them as generic, non-channel bags. Similarly, if you don't label the third party screen as "genuine apple", you're not infringing copyright.

  > Veilid is an open-source, peer-to-peer, mobile-first networked application framework, with a flagship secure messaging application named VeilidChat. Veilid is conceptually similar to IPFS + Tor, but faster and designed from the ground-up to provide all services over a privately routed network. The network also enables development of distributed applications without a 'blockchain' or a 'transactional layer' at their base. Veilid can be included as part of user-facing applications or run as a standalone server for power users who wish to help build the network.
I thought HN would find this interesting :)

Most likely they just mean that every time they register a new account, they get their backup yubikey out and add the account to it too

It's not possible to clone yubikeys

I find it kind of amusing that people still blindly follow their ideology without being pragmatic about things

If hardware doesn't (or barely) works with a free/libre implementation, why do they (gnuboot) refuse to use the proprietary binary blob and in the meantime start development on a better free version?

The lack of pragmatism astounds me

The technological implementation aspect is not generally what stops new ideas. And, I think the technical aspect comes after deciding how a CBDC will look like, since it depends on what you want to achieve with a CBDC.

Looking at the different aspects of topics like Privacy, Auditability and how the CBDC relations to the government will give you vastly different implementations of CBDC.

For example:

1) Privacy: is every transaction in the blockchain completely public? Is it only accessible to certain authorized parties? Is it private by default and only accessible with a "view" key like with Litecoin or Monero? All of these questions depend on what the goal of the goal of the currency is. Having a more private currency will make it harder to audit, but you probably do not want to make it completely public in the same way that you'd probably not want to make all your bank transactions public.

2) Considering auditability: How can you make sure then money in a transactions didn't come from illegal gains? If all transactions are completely private (even to the central bank), how do you do KYC and comply with AML regulation? Currently, banks do KYCs on every customer, but if the blockchain for the CBDC doesn't have access restrictions, who will do the auditing? Additionally, how would a tax collection agency like the IRS confirm that you're actually telling the truth about your transactions? They'll need to be able to access those transactions at some point too for audit purposes.

3) Considering the relationship with governmental power: does the government have the power to view every transaction at any time? What powers do they have in the blockchain? Are they the ones that develop the code?

Considering all these questions, you can start to get a relatively good idea for what a CBDC would look like: 1. There are probably some access restrictions since someone needs to do KYC. 2. The blockchain needs to be private by default, but accessible by anyone auditing.

Considering privacy, you could set up a system where authorized transaction processors (such as regional or national banks) are permitted to create wallets for their clients after doing KYC. The transactions could be private by default but have a key to allow the KYC provider to audit transactions an comply with audit requests.

Really cool use of the protocol and yubikey though! I didn't know yubikeys could be used like that.

Personally I'd rather not expose anything at all from my home network since it's easier to not have to think about keeping my reverse proxy up to date so I don't get pwned by a 0-day. AFAIK you can also use cloudflare's tunnels or tailscale's new funnels to access your internal network without needing to have tailscale or cloudflare's daemon installed in anything but one of your servers, but that also moved the root of trust to a third-party (unless you self-host your own tailscale infra! But that's also way more work)

Really cool project overall. I might try it out I know the future when I have a fully developed homelab
