> AMD is in the process of responding to the claims, but was only given 24 hours of notice rather than the typical 90 days for standard vulnerability disclosure. No official reason was given for the shortened time. 90 days is not a standard. Nothing was shortened. People are allowed to publish their research whenever they like. Vendor advance notification is optional. Full, immediate disclosure is responsible.

"Full, immediate disclosure is responsible." says who?

Me.

Not allowed to say that here.

>All of the exploits require elevated administrator access, with MasterKey going as far as a BIOS reflash on top of that. CTS-Labs goes on the offensive however, stating that it ‘raises concerning questions regarding security practices, auditing, and quality controls at AMD’, as well as saying that the ‘vulnerabilities amount to complete disregard of fundamental security principles’. This is very strong wording indee…

Yeah it's suspicious. The website[1] has many fancy infographics, marketable names and fear mongering but you have to dig into the whitepaper[2] to find any details about the actual vulnerabilities. And even then it starts only on page 8 of 20 and you discover that it's vulnerabilities targeting the secure boot infrastructure and you need local admin to exploit them. It's not good but it's not a new Spectre or Meltdo…

It's possibly even more nefarious than that: 1) execute a series of puts on AMD, 2) release exploit 3) profit. If you execute an option with a far time horizon and give the company enough time to mitigate their vulns, then I think this is not an irresponsible thing to do (as it incentivises the company to actually do something), but with 24 hours notice...

A few (far from all!) software vendors realistically might be able to respond and issue a patch in 24 hours. But a hardware vendor cannot. See Intel's recent debacle [1] for what happens when a silicon vendor rushes a security fix out of the door without going through a proper multi-week QA cycle.

Hiring a PR firm before disclosing to the vendor is not responsible. Briefing select press before disclosing to the vendor is not responsible.

24hrs notice is unheard of. Who works for CTS-Labs? Attaching your name to a company like that should disqualify you from any future jobs in the security space.

They seem to have 3 employees on LinkedIn. The co-founders, at least, seem to have listed experience in security & security consulting.

And the users downstream of bugs that are made more widely vulnerable--because, as anyone who saw how, as an example, previously rare MitM attacks became commonplace after Firesheep etc. were publicized, obscurity is in fact a component of security--are...?

Well, fuck 'em, I guess.

Responsible disclosure, contrary to the super-cool leet kid notions expressed by people with who choose to exhibit an underdeveloped social conscience, is not doing a solid for the companies who have vulnerabilities. It's for the users who consume things. Security researchers are effectively taking upon themselves a role of public service. That comes with responsibilities to the public, not to AMD or whoever.

Meanwhile, this crew looks like they briefed the media before telling the vendor, which is all kinds of fucked.

Politeness is optional too, but people still prefer to not be needlessly rude. It is quite normal to balance doing your job with trying to reducing harm to users who had nothing to do with this.
